TL;DR
Start slab lift in Alabama with an entity, a free EIN, a city or county business license, and general liability insurance. A state general contractor license is required once one undertaking hits $50,000 (Ala. Code § 34-8-1). Residential repair can pull in the Home Builders Licensure Board. Confirm current fees with those boards. Most driveway and patio lifts finish in a day. There is no official statewide price.
How do you actually start slab lift in Alabama?
You start with paper, not a foam rig. Form an Alabama entity or register a foreign one, pull a free EIN from the IRS, then buy the city or county business license where you hang your hat. After that, call two state boards with a one-page scope of work and ask whether your mix of driveways, patios, warehouse floors, and interior slabs needs their card. [6] [10]
Fees, exam names, and classification codes change. Confirm them on the board's current application. I would not order a proportioner until general liability is bound and you know which license, if any, the work triggers.
Most first-year slab lift Alabama operators live on residential concrete that settled over wet clay or bad fill. That is a local soils problem, not a national franchise story. Read the county soil survey before you promise a lift the subgrade cannot hold. [12]
The rest is ordinary contractor hygiene. Written proposals. Photos before you drill. A laser or optical level so you can prove the lift. A plan for the day a slab turns out to be a structural foundation with a cracked grade beam. That last one is how people wander into home-builder territory without meaning to.

Do you need a license for slab lift in Alabama?
Yes, you need local business paper on day one. A state contractor license depends on the job, the dollar amount, and whether the work is residential home improvement. Alabama does not issue a card that says slab lift.
The Alabama Licensing Board for General Contractors treats you as a contractor when you undertake construction, alteration, maintenance, repair, rehabilitation, remediation, or similar work "where the cost of the undertaking is fifty thousand dollars ($50,000) or more." That line is in Ala. Code § 34-8-1. [1] Acting in that capacity without the license is unlawful under Ala. Code § 34-8-2. [2]
An $8,000 driveway lift for a homeowner is not an ALBGC job by itself. Stack enough work into one contract, or take a warehouse floor that crosses $50,000, and it is. Do not split one undertaking into three invoices to dodge the threshold. Boards have seen that trick for decades.
Residential work has a second door. The Home Builders Licensure Board licenses residential home builders, and the statute covers construction plus repair, improvement, or reimprovement of a residence. Ala. Code § 34-14A-5 requires that licensing. [3] Exemptions live in Ala. Code § 34-14A-6 and have long included certain small undertakings and people already licensed as general contractors. The dollar figure in that exemption has been amended before. Confirm the current text with the board before you treat a patio as exempt. [4]
Every city and many counties still want a municipal business license even when no state construction board cares about your $4,200 mudjacking job. Pull that local license first. It is the piece a police officer or revenue clerk can ask for this afternoon.
Which Alabama board do you call first?
Call the building official in the city where the slab sits, then call ALBGC and the Home Builders Licensure Board with the same written scope. Do not ask Facebook which card you need.
ALBGC is the board for the $50,000-and-up contractor definition. It assigns classifications and a bid limit tied to your financial statement. Slab lifting is not a named classification on most older lists. Concrete, building, or a specialty class may fit. Send the board a short description (polyurethane injection or cementitious slurry, residential slabs, commercial floors, no new foundations) and ask them to name the class. Guessing the class on an application is how people stall. [1] [2]
The Home Builders Licensure Board is the board when the work is repair or improvement of a residence. An attached garage slab, a sunken interior floor, or a patio that is part of the dwelling package can land here even when the check is under $50,000. A parking lot at a tire shop does not. [3]
Already hold an ALBGC license? Ask HBLB whether that license covers the residential jobs you want. The exemption statute is written for that situation, but staff still have to apply it to your facts. [4]
Public work is a third stack. School, city, or ALDOT pavement lifting can add bid bonds, certified payroll, and a licensed prime. ALDOT publishes its own construction specifications for highway work. That book is not your residential driveway contract, but it is the document owners copy when they want "DOT-style" slab jacking language. [15]
For a side-by-side of what another Sun Belt state asks, how to start slab lift in Arizona and the slab lift license in Arizona pages help only as contrast. Do not import their classes into Montgomery.
How do you set up the company paper in Alabama?
File an entity with the Alabama Secretary of State, then get tax accounts. A domestic LLC certificate of formation has been $200 in recent SOS fee schedules. Confirm the current figure on the Secretary of State's business entity fee list before you card it, because the office can change a fee without calling you. [6]
I would form an LLC, not a sole proprietorship, if I planned to drill other people's houses. The LLC does not make you judgment-proof. It does keep the job from landing on your personal checking account by default. Skip the $1,200 online "we form it for you" upsell. The SOS portal is the actual filing.
Get an EIN from the IRS the same day. It is free on the IRS EIN application page. Anyone who charges you for an EIN is selling a form the government already gives away. [10]
Register for the Alabama taxes you actually owe. Most entities file the business privilege tax with the Department of Revenue. Statute sets a floor. The privilege tax "shall not be less than $100" under Ala. Code § 40-14A-22. Confirm the current form and due date on the Department's business privilege tax page. [7] [5]
Sales and use tax is where new concrete outfits get sloppy. Alabama generally treats contractors as the consumers of the materials they install into real property. You often pay tax when you buy foam, slurry cement, and rebar, and you do not add a separate sales tax line on a completed real-property repair the way a retailer would. The Department of Revenue's contractors guidance is the document to read, not a forum post. Selling leftover material off the truck as a retail sale is a different tax event. [8]
Add the municipal business license, a written contract template your lawyer actually reviewed, and a simple job folder (scope, photos, level readings, invoice). That is the paper path. Fancy branding can wait.
What insurance and workers comp do you need in Alabama?
Buy general liability before the first hole. Alabama does not hand you a contractor card just because you bound a policy, and the state does not publish a magic GL limit for slab lift. GCs and property managers will. $1 million per occurrence is the number I see demanded most often. Confirm what your first three target customers require so you do not buy the wrong endorsement twice.
Ask the agent for the additional-insured and waiver-of-subrogation wording those customers use. Polyurethane injection and cement slurry both create property-damage claims (overlift, stained carpets, a cracked tile floor you did not photograph). A cheap policy that excludes "your work" or pollution from chemical injection is a waste of money.
Workers' compensation is a head-count rule with sharp edges. Ala. Code § 25-5-50 says the article "shall not be construed or held to apply to any employer who regularly employs less than five employees in any one business." [9] Regularly is the word that bites people who run a busy summer crew. The Alabama Department of Labor runs the workers' compensation program and publishes employer guidance. Confirm your count with them if you use 1099 help who look like employees. [14]
Federal OSHA still applies to private construction in Alabama. The state is not a private-sector State Plan state. If you have employees, the silica rule for construction is live the moment you drill concrete. 29 CFR 1926.1153 is the standard. Wet methods, a shroud, or a vac is the boring version of compliance. Skipping it to save twelve minutes is how you buy a citation. [11] [13]
I would also carry hired and non-owned auto if employees run personal trucks to sites, and inland marine on the proportioner once you own one. Auto claims wreck more small contractors than foam chemistry does.
How much does it cost to start slab lift in Alabama?
Nobody publishes an honest statewide startup total. The closest real numbers are filing fees and statutory thresholds, not Instagram rig tours.
Paper is the cheap part. A domestic LLC has been $200 at the Secretary of State. Privilege tax starts at a $100 floor. A city business license might run tens or hundreds of dollars depending on the municipality and your gross receipts schedule. Confirm each current amount with SOS, Revenue, and the city clerk. Do not trust a blog fee table. [6] [7]
Insurance will outspend the filing fees. A new concrete repair outfit with a truck and a small crew often pays more for GL and commercial auto in year one than it pays every board combined. I will not invent a premium. Your agent prices the zip code, the claims history, and whether you inject isocyanate foam.
Tools split into two piles. Pile one is what I would buy first: a reliable used truck, a hammer drill or core rig, a generator, a 4-foot level plus a rotary laser, PPE, crack repair, and a camera. That pile keeps you able to bid and to document. Pile two is the plant. A cementitious mudjacking pump is the smaller capital bet. A dual-component polyurethane proportioner, hoses, and heated gear is the large one. Manufacturer training is worth it for the gun. It is not a state license.
Waste of money: franchise "territories" sold before you have pulled a Birmingham or Huntsville business license, national certification stickers Alabama boards do not recognize, and a brand-new box truck wrap. Get three paying jobs in one county first.
Want bid sheets that match how this work is actually quoted? SlabLiftPath sells a $149 one-time Mix + Bid-per-Sqft Kit at /start. Use it or a spreadsheet. Either beats guessing foam yield on a napkin.
How much does slab lift cost in Alabama?
There is no official Alabama price for slab lift. No board sets a per-square-foot rate. Anyone quoting a single statewide average is inventing a number.
Homeowners usually pay by the slab, by the square foot, or by the void. Polyurethane jobs often price higher per foot than cement slurry because the material costs more and the traffic-ready time is shorter. A small sunken patio or walkway can land from several hundred dollars into the low thousands. A dropped interior floor or a warehouse aisle is a different bid. Depth of the void, access, furniture, and whether you have to saw-cut or stitch cracks will move the number more than the county line will.
I would bid from measured lift area, estimated void thickness, and a waste factor for foam or slurry, then add mobilization. Do not copy a national "$8 a square foot" blog post onto a Mobile coastal fill slab and a Madison County clay slab. They do not behave the same. [12]
Commercial work should be unit-priced with a not-to-exceed or a daily rate for unknown voids. If the contract might cross $50,000, stop and check the ALBGC question before you sign. [1]
Give homeowners a written range, a note about conditions you cannot see until you drill, and a cap on extra material. The contractors who get yelled at are the ones who sold a fixed miracle from the curb.
How long does slab lift take in Alabama?
Most residential driveway, walk, or patio lifts are a same-day job. A two-person crew can drill, inject, and clean a typical homeowner slab in a few hours if access is easy and the void is not a mystery cavern.
Polyurethane foam often supports foot traffic in minutes once it expands and sets. That is chemistry, not a certificate of occupancy. Cementitious slurry (mudjacking) usually needs a longer wait before cars roll. I treat slurry as an overnight or next-day drive surface unless the mix and the weather say otherwise. Heat, rain, and a shaded north slab change those clocks. Nobody has a published Alabama cure study that I trust more than the material data sheet in your trailer.
Interior house slabs take longer on the clock even when the injection is fast. You move furniture, protect floors, and chase material that can travel. A warehouse night shift can cover more square feet because you are not stepping over toys.
Add board and permit time on top of field time when the job is structural or the city says so. Licensing and permit desks do not publish a guarantee. Confirm current processing with the board or building department. Do not promise a homeowner that "the city always turns this around in 48 hours."
If a slab is still moving because water is still running under it, lifting day is the wrong first day. Fix the downspout and the grade. Then lift.
Do you need a building permit for slab lift in Alabama?
Sometimes. Alabama leaves building permits to cities and counties. There is no statewide slab-lift permit form.
Call the building department for the address, not the county where your LLC sits. Unincorporated land and a city lot two miles apart can disagree. A floating backyard patio may get a shrug. A sunken interior house slab, a garage pulling away from the wall, or anything that looks like foundation repair often gets a permit and sometimes an engineer's note.
I would describe the method in one sentence. "Inject expanding polyurethane through drilled holes to re-support an existing slab on grade. No new footings." Vague words like "foundation work" make clerks escalate you into a full residential addition review.
Public sidewalks and anything in a right-of-way need the public-works desk more than the building desk. HOA rules are not law, but they can still stop you in the driveway Saturday morning.
Keep the permit card, photos, and as-built lift readings in the job file. The next buyer of that house will ask. So will the home inspector who does not understand foam.
California's permit culture is heavier than Alabama's. If you are comparing paper stacks, how to start slab lift in California shows a denser board structure. Do not copy it here.
What equipment is worth buying in year one?
Buy measurement and documentation first. A rotary laser and a notebook of before-and-after shots will settle more arguments than a shiny proportioner. Drill bits are a consumable. Budget them.
For material delivery, pick one method and get good. Cement slurry equipment is older tech, heavier, and messy. It is also more forgiving while you are still learning how Alabama fill behaves. Polyurethane gear is cleaner and faster to traffic, and it is less kind to sloppy yield math. Running both lines in month one is how you own two half-learned trades.
I would rent or demo a plant on the first few commercial bids if the manufacturer allows it. Owning a five- or six-figure rig that sits in a Prattville shop while you chase licenses is a bad year.
Skip the specialty truck body until the rig is paid for by jobs. A flatbed and ratchet straps look ugly and make money. Watch chemical storage rules for isocyanate components. Heat in an Alabama August trailer will ruin product and create a safety mess.
Training: take the manufacturer's injection class. Add an OSHA-10 if you have employees. Neither class replaces ALBGC or HBLB. Anyone selling you a "licensed slab lift technician" diploma as if Montgomery issued it is selling merch.
What Alabama soil and job mix should you plan for?
Plan for water and bad compaction before you plan for magic foam. North Alabama sits on carbonate rock. Sinkholes and throat collapses are a real geologic hazard, not a sales script. The USGS sinkhole overview is the plain-language primer. If the slab dropped because the ground opened, injection is not a cave-filling business unless you are staffed and insured for that. Send that one to an engineer. [16]
Central and parts of north Alabama also fight fat clays that shrink and swell with moisture. The house did not "settle one inch in July" because the foam wore off. The clay moved. Gutters, short downspouts, and beds piled against brick will undo a pretty lift. Keep water away from the foundation and the lift lasts.
The Gulf Coast adds fill, high water tables, and storm washout under driveways. Probe the void. Do not assume a uniform two-inch gap because the corner is down two inches.
NRCS Web Soil Survey is free and is the map I would open before I promised a subdivision's worth of driveways. [12]
Job mix that actually shows up: homeowner driveways and patios, storefront walks, pool decks (watch structural decks), and the occasional warehouse joint. Interior living-area slabs on grade are profitable and politically sensitive. One overlift under a tile floor can erase a month of patios.
Arkansas shares some of this Mid-South clay story. Their license path is still their own. Read slab lift license in Arkansas if you bid both states. Colorado's soils and boards are a different climate. Use how to start slab lift in Colorado only as a reminder that you cannot copy-paste a playbook.
What would I skip, and what would I do first?
I would do this in order. Entity and EIN. City business license. GL policy that actually covers injection. Written scope to ALBGC and HBLB. Soil homework on the first county I want to work. Then tools. Then marketing.
I would skip buying a territory, paying for a national association decal that no Alabama inspector asks for, and bidding structural underpinning on day one. Slab lift is not helical piles. When a grade beam is broken, you are in a different trade and a different license conversation.
I would also skip promising lifetime warranties on a clay site you have not drained. Offer a straight workmanship term you can honor.
Confirm every fee, exam, and processing note with the board that collects the money. This site is not a law firm and not a permitting desk. No one can honestly guarantee an approval date.

Frequently asked questions
Do you need a license for slab lift in Alabama?
You need a city or county business license to operate. A state general contractor license is required when one undertaking costs $50,000 or more under Ala. Code § 34-8-1. Residential home repair can also require a Home Builders Licensure Board license. Confirm your exact scope with both boards. Manufacturer training is not a state license.
How much does slab lift cost in Alabama?
No Alabama board sets a price. Small homeowner patios and walks often land from several hundred dollars to a few thousand, depending on void depth, access, and method. Polyurethane usually prices higher per foot than slurry. Commercial floors are bid separately. Get three local written quotes. Anyone citing one official statewide average made it up.
How long does slab lift take in Alabama?
Most residential driveways and patios are finished the same day, often in a few hours of on-site work. Polyurethane is commonly walkable the same visit. Cement slurry usually needs a longer wait before vehicles. Interior and warehouse jobs run longer because of access and furniture. Permit review, when required, is extra time you cannot honestly guarantee.
Can I lift slabs under $50,000 without an ALBGC license?
The ALBGC definition in Ala. Code § 34-8-1 keys off an undertaking of $50,000 or more. A single smaller driveway job is outside that definition. Do not split one project to stay under the line. Residential work can still need the Home Builders board. Cities still want a business license at any dollar amount.
Does the Home Builders Licensure Board cover driveway lifting?
It can, when the work is repair or improvement of a residence rather than a purely commercial slab. Ala. Code § 34-14A-5 requires residential home builders to be licensed. Exemptions in § 34-14A-6 have included small undertakings and licensed general contractors, but the text changes. Send HBLB your scope and ask. Do not assume a detached store walk is the same as a house slab.
Do I need an LLC to start slab lift in Alabama?
No statute says slab lift must be an LLC. Sole proprietors can pull local licenses. I would still file an LLC with the Secretary of State before drilling other people's houses. The domestic certificate of formation has been $200 in recent fee schedules. Confirm the current fee. Get a free EIN from the IRS the same day.
Is workers' comp required for a two-person slab lift crew?
Ala. Code § 25-5-50 says the workers' compensation article does not apply to an employer who regularly employs less than five employees in any one business. A true two-person shop is usually outside that article. Regular extra hires can change the count. Confirm facts with the Alabama Department of Labor. OSHA still applies if you have employees.
Do I charge Alabama sales tax on a slab lift invoice?
Often you do not add retail sales tax on a completed real-property repair. Alabama generally treats contractors as consumers of installed materials, so tax is paid when you buy foam or slurry cement. The Department of Revenue contractors page is the rule set. Selling leftover material at retail is different. Confirm your facts with Revenue before you print invoices.
What contractor classification do I pick for slab lift?
Alabama does not print a classification titled slab lift. ALBGC uses classes such as building, concrete, or specialty. Send the board a short method statement and let them name the class. Picking the wrong class on your own is how applications stall. Bid limits follow your financial statement. Confirm both items on the current application.
Can a Georgia or Florida contractor just come work in Alabama?
Not above the state thresholds, and not without local paper. Out-of-state firms still file with the Secretary of State as a foreign entity, pull municipal licenses, and meet ALBGC or HBLB when those statutes apply. Other-state cards are evidence, not a hall pass. Confirm reciprocity talk with the board. Do not start a $60,000 floor on a Georgia wallet card.
Do I need a permit to lift a patio in Alabama?
It depends on the city or county, not on a statewide patio rule. Many places ignore a simple floating patio lift and care a lot about interior house slabs or anything that looks structural. Call the building department for the job address. Work in a public right-of-way needs public works, more than a building permit.
Is manufacturer foam training an Alabama license?
No. Manufacturer classes teach you how not to wreck their chemical and how to run the gun. ALBGC and the Home Builders Licensure Board do not treat those certificates as a substitute for a statutory license. Keep the training card in the truck. Do not advertise yourself as "state licensed" on the back of a vendor diploma.
How do I confirm current Alabama board fees?
Use the live fee schedule or application on the Alabama Licensing Board for General Contractors site, the Home Builders Licensure Board site, the Secretary of State business entity fee list, and the Department of Revenue privilege tax page. Ignore old blog tables. This publication does not publish a fee the board can change tomorrow, and it does not promise processing times.
What insurance limits do Alabama GCs usually ask slab lift subs for?
The state does not set a slab-lift GL number. General contractors and managers commonly ask for $1 million per occurrence, additional insured status, and a waiver of subrogation. Some add pollution or auto requirements if you haul chemicals. Get the sample certificate they want before you bind a cheap policy their risk desk will reject.
