Foundation repair in the Birmingham area typically costs $4,500 to $20,000 to stop a settling or sinking foundation, while a single crack runs $250 to $800 and each helical pier runs $2,000 to $4,000 installed, according to HomeGuide's 2026 foundation repair and helical pier cost guides. The pier count and the depth to firm soil move the number most. NOAA's 1991 to 2020 normals give the Birmingham airport station 56.62 inches of rain a year, and clay that swings between soaked and dry is what shifts most footings here. BDry Alabama inspects the whole house before recommending anything, and the free inspection sets your exact price.

We are a local foundation repair and waterproofing contractor and we stand behind every job. You are not handed off to a subcontractor. Every job follows the same disciplined process:
The Birmingham area is wet in winter and spring and dry in early fall. NOAA's 1991 to 2020 climate normals for the Birmingham airport station put March at 5.66 inches of rain, the wettest month, and October at 3.34 inches, the driest, with 17.7 days a year that bring an inch or more. Clay soil swells when it is saturated and shrinks as it dries, so the footing that was pushed up in March can lose support by October. That yearly swing is why cracks tend to show up or widen in late summer and fall, and why a crack that looked stable in April is worth measuring again. A digital foundation scan from BDry Alabama records level readings across the house, so the next reading can be compared against a real baseline.
Foundation repair in the Birmingham area typically costs $4,500 to $20,000 for a settling or sinking foundation, according to HomeGuide's February 2026 foundation repair guide, which puts a single crack repair at $250 to $800 and bowed wall repair at $5,000 to $15,000. Helical piers, the most common fix for a dropping corner, run $2,000 to $4,000 each, so a three pier repair lands near $6,000 to $12,000 and a ten pier repair near $20,000 to $40,000. What moves a house from the low end to the high end is the number of piers, how deep firm soil sits, and whether a basement wall also needs bracing. BDry Alabama publishes no chart price; the free inspection ends with one written number.
HomeGuide's February 2026 helical pier guide puts residential helical piers at $2,000 to $4,000 per pier installed, with most homeowners paying about $3,000 per pier. The count depends on how much of the foundation has settled and how heavy that section is: HomeGuide's table runs from $6,000 to $12,000 for three piers to $16,000 to $32,000 for eight. A pier is a steel shaft with helical plates that is turned into the ground until it reaches load bearing soil, and because the installer reads the torque as it goes in, the capacity is verified during installation rather than assumed. BDry Alabama explains where each pier goes and why before anything is installed.
Mostly water moving through clay, and sometimes the ground itself. Clay subsoil swells when it is wet and shrinks as it dries, and NOAA's 1991 to 2020 normals give the Birmingham airport station 56.62 inches of rain a year with a dry early fall, so that cycle repeats every year. The Geological Survey of Alabama adds two local causes: "In Alabama, the most common causes of land subsidence are the development of sinkholes in areas underlain by soluble carbonate rocks or ground collapse above abandoned mines." The metro has both carbonate valleys and old coal and iron workings. Poorly compacted fill, tree roots and downspouts that dump water at the wall round out the list, and the inspection is how you learn which one is under your house.
It depends on its shape and whether it is moving. A thin vertical crack in a poured wall is often shrinkage from curing and may only need sealing. A stair step crack in brick or block, a horizontal crack across a basement wall, or one that widens or reopens after patching points to movement or soil pressure and deserves a measurement. HomeGuide's 2026 data puts crack repair at $250 to $800 per crack, done with epoxy injection for a structural bond or polyurethane injection for a flexible watertight seal. If water is pushing through, sealing alone will not hold, and the drainage has to be dealt with too. BDry Alabama checks the size, direction and activity of each crack before recommending anything.
A bowing wall is being pushed in by wet soil, so the fix is to hold it against that pressure with steel beams or carbon fiber straps anchored to the footing or the framing. HomeGuide's October 2025 guide prices steel or carbon fiber straps at $85 to $280 per linear foot and wall anchors at $80 to $150, which puts a typical 20 foot wall at about $1,600 to $11,000 depending on the method and how far it has moved. Walls with minor bowing are stabilized; walls that have moved a lot may need a different structural answer. BDry Alabama covers its wall support systems for the life of the structure against further inward movement, and pairs the bracing with drainage when water is the cause.
It is a set of level readings taken across the whole house instead of a look at one crack. BDry Alabama measures the floor every five feet from a zero point and turns the readings into a color coded map that shows which areas are stable and where the low points are. That map does three jobs: it shows where piers or supports belong, it gives a buyer, seller or home inspector real numbers during a sale, and it creates a baseline so a follow up scan can prove the repair held. Ask about it when you book your inspection; members of the BDry Elite Gold plan get one every year.
Usually because the framing under the floor has lost support: a girder that has settled, joists softened by years of damp air, or piers that were spaced too far apart when the house was built. BDry Alabama installs adjustable steel support posts on footings under the sagging beam, then adjusts them gradually so the framing is corrected under control rather than jacked all at once. HomeGuide's February 2026 sagging floor guide puts sistering a damaged joist at $150 to $325 per joist and major structural reinforcement at $4,500 to $20,000 or more. Floor support systems carry a two year warranty from BDry Alabama. If moisture caused the damage, sealing the crawl space afterward is what keeps it from coming back.
Often, yes. Poly lifting injects high density polyurethane foam under a settled slab through small holes; the foam fills the voids, lifts the slab back toward level and does not wash out. HomeGuide's November 2025 concrete leveling guide prices polyjacking at $8 to $25 per square foot, against $4 to $9 for traditional mudjacking, and notes the foam goes in through holes about 5/8 inch across and cures "in just 15 minutes." It suits driveways, sidewalks, patios, pool decks, garage floors and steps where the concrete itself is sound. BDry Alabama looks at why the slab sank first, because a slab lifted over soil that is still washing out will sink again.
Keep people and pets away from it first. The Geological Survey of Alabama tells homeowners to put a barrier around the hole, contact their insurance company, and consider a geologist, a geotechnical or civil engineer, or a foundation repair specialist to assess it; if it touches a public road, sidewalk or city drainage, call the city or county engineer. Do not fill it with trash or yard waste. Alabama's Cave Protection Law, in Title 9, Chapter 19, Section 4 of the Code of Alabama, makes it a misdemeanor to dump chemicals, refuse or other harmful material into sinkholes because they lead straight to groundwater. GSA also notes that a ground depression can have non geologic causes, such as leaking water or sewer lines, abandoned wells, septic tank collapse or buried construction material. BDry Alabama can check whether the house itself has moved.
It depends on the system, and the terms are published. Helical piers are covered for the life of the structure against further vertical settlement. Wall support systems are covered for the life of the structure to prevent inward wall movement. Floor support systems are covered for two years. If you sell the house, BDry Alabama must be notified within 60 days of the sale, and the new owner receives two years of coverage, with extended coverage possible after an inspection. The warranty does not cover flooding, extreme weather, or damage to belongings, and it can be voided if the installed system is altered without approval. Gold members of the BDry Elite plan get free warranty transfers.
Usually not. HomeGuide's February 2026 foundation repair guide says foundation repair "is usually considered part of regular home maintenance and is not covered by homeowners insurance," with the exception of damage from a covered event such as a burst pipe or a fire. Gradual settlement from soil that swells and shrinks is the kind of damage that maintenance language is written for, so read the exclusions and any endorsements in your own policy before assuming either way. If you do file a claim for a sudden loss, a digital foundation scan and dated photos give the adjuster measurements instead of descriptions, and BDry Alabama can provide both.
Yes. BDry Alabama offers two lenders, and terms depend on credit approval. Through GreenSky there is a 15 month promotional plan with no interest if paid in full within 15 months, and fixed rate plans of 7.99 to 19.99 percent APR for up to 120 months. Through Upgrade there are fixed monthly plans, including a 7 year plan at 9.99 percent APR with no early payoff penalty and a 5 year plan at 8.99 percent APR. For a $12,000 pier job that is the difference between waiting another wet season and stopping the movement now. The inspection and the written price come first, so you know the amount before you apply.
Call BDry Alabama at 205 942 1976 or send the form, Monday through Friday from 7 in the morning to 6 in the evening. A photo of the crack or the door that sticks helps, but you do not need to know what is wrong. At the visit we check the cracks, the doors, the floors and the drainage, and explain what is moving and why. You leave with the repair method, the pier or brace count, and one written price, and there is no pressure to decide on the spot. If a structural engineer's letter is needed, which HomeGuide prices at $500 to $3,000, we say so at the visit rather than after you sign.
Most sinking concrete slabs are fixed with polyurethane foam lifting, which costs $8 to $25 per square foot according to the typical cost table on this page, and a driveway, patio or walkway is usually done in one day. The crew drills holes about 5/8 inch wide and injects expanding foam under the slab. The foam fills the voids and raises the slab back to level, then the holes are patched. The foam usually cures enough to walk on within about 15 minutes. The price depends on how big the slab is, how far it has dropped, how large the empty space underneath is, and how easily equipment can reach it. If the slab sank because the soil under the house foundation is failing, lifting the slab alone will not hold. That job becomes a settling foundation repair, listed at $4,500 to $20,000 on the same table, and it sometimes needs a structural engineer report at $500 to $3,000. Fixing gutters and grading first keeps water from washing out the soil under the slab again, and BDry Alabama does the poly lifting and drainage work with its own crews.
Foundation repair in Alabama typically runs $4,500 to $20,000 to fully repair a settling or sinking foundation, according to the typical cost table on this page, while sealing a single crack with epoxy or polyurethane injection costs $250 to $800. The biggest driver is how many helical piers the house needs, since the same table puts each pier at $2,000 to $4,000, so a corner that settles and needs four piers lands in a very different tier than a full side that needs ten. Bowing basement walls are priced by length: $85 to $280 per linear foot, or $1,600 to $11,000 to brace a typical 20 foot wall with steel or carbon fiber straps. Lifting a sunken slab with polyurethane foam runs $8 to $25 per square foot. If a lender, insurer or permit office asks for a structural engineer report, add $500 to $3,000. Crawl space access, landscaping over the repair line and soil conditions also change the labor. BDry Alabama performs this work with its own crews.
Foundation repair in Montgomery, AL typically costs $4,500 to $20,000 for a settling or sinking foundation, according to the typical cost table on this page. The number moves with how many piers the structure needs, since helical piers run $2,000 to $4,000 each in that table, and with how much of the home has settled. A bowing wall braced with steel or carbon fiber straps runs $85 to $280 per linear foot, or $1,600 to $11,000 for a typical 20 foot wall. Injecting an individual crack costs $250 to $800, and a sunken slab lifted with polyurethane foam costs $8 to $25 per square foot. A structural engineer report, $500 to $3,000 when required, adds to the total. Most residential pier jobs take 1 to 3 days of crew time. Insurance coverage depends on the policy and the cause of damage, and any claim is between the homeowner and the insurer. BDry Alabama's own crews inspect and document the damage and perform the repair.
Helical pier installation typically costs $2,000 to $4,000 per pier, according to the typical cost table on this page, and most settling foundations need several piers rather than one. Piers are usually spaced about 6 to 8 feet apart along the affected wall, so a 30 foot section often takes 4 to 6 piers, which is why a full settlement repair runs $4,500 to $20,000 on the same table. The per pier price climbs with the depth to load bearing soil, since every extra shaft extension adds steel and labor. Access changes the number too: interior piers cut through a slab, tight crawl spaces, and decks or landscaping near the footing all add excavation time. When a lender, insurer, or city requires a structural engineer report, the typical cost table on this page lists that at $500 to $3,000. Most residential pier jobs take 1 to 3 days of crew time. BDry Alabama installs helical pier systems with its own crews and sets the pier count after measuring the settlement on site.
Foundation repair in Decatur, AL typically runs $4,500 to $20,000 for a settling or sinking foundation, according to the typical cost table on this page. Helical piers cost $2,000 to $4,000 each by that same table, and most residential pier jobs take 1 to 3 days of crew time. Smaller fixes cost far less: crack injection is $250 to $800 per crack, and a bowing wall braced with steel or carbon fiber straps is $85 to $280 per linear foot, or $1,600 to $11,000 for a typical 20 foot wall. Sunken concrete slabs lifted with polyurethane foam run $8 to $25 per square foot, and a driveway, patio or walkway is usually finished in one day. The number moves with how many piers the home needs, how far it has settled, the length of any bowing wall, and whether a structural engineer report, listed at $500 to $3,000 in the same table, is required. BDry Alabama's own crews perform the work after inspecting the home and documenting the damage.
Sagging, uneven floors in an Alabama house usually come from one of two causes: failing supports under a crawl space floor, or a settling foundation. A full settling foundation repair runs $4,500 to $20,000 according to the typical cost table on this page. Over a crawl space, the usual causes are beams spaced too far apart, piers that have sunk, or joists softened by rot from damp air. Those are fixed with adjustable steel floor supports and wood rot repair. When the foundation itself is moving, piers are driven down to stable soil. The same table lists helical piers at $2,000 to $4,000 each, so a job needing 5 piers and one needing 12 are very different in cost. A structural engineer report, when one is required, adds $500 to $3,000 according to that table. The price also depends on how many feet of beam need support, how much wood has rotted, and whether moisture control or crawl space encapsulation is needed to keep the rot from coming back. BDry Alabama does this work with its own crews.
