Foundation crack repair in the Birmingham area typically costs $250 to $800 per crack when the crack is not structural and can be sealed by injection, and $1,000 to $5,000 or more for minor structural cracks such as horizontal or stair step cracks, according to HomeGuide's July 2025 foundation crack repair guide. Epoxy injection bonds a stable crack back together; polyurethane stays flexible and seals out water. The shape of the crack, its width and whether it is still moving decide which repair it needs. BDry Alabama inspects the size, direction and activity of each crack before recommending anything, and the inspection is free.

A crack is priced by what it means, not by its length. These are typical installed ranges from HomeGuide's July 2025 national guide, not quotes; whether your crack is cosmetic, leaking or structural is what a free inspection settles.
| Crack type or repair | Typical installed range |
|---|---|
| Hairline, vertical or diagonal crack, injected | $250 to $800 per crack |
| Structural crack, minor (horizontal or stair step) | $1,000 to $5,000 or more |
| Structural crack, major foundation problem | $10,000 to $30,000 or more |
| Carbon fiber strips over a cracked wall | $900 to $2,000 per crack |
| Structural engineer, when required | $500 to $3,000 |
| Interior drainage when a crack keeps leaking | $4,000 to $17,000 |

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:
Many cracks here are not fixed in size. NOAA's 1991 to 2020 climate normals for the Birmingham airport station put the wettest month in March at 5.66 inches of rain and the driest in October at 3.34 inches, and clay subsoil swells and shrinks right along with that cycle. A crack can look tight in spring and noticeably wider by early fall. That is why a single look is not enough to call a crack stable. Mark both ends with a pencil, write the date beside them, and photograph the crack with a coin or ruler for scale; if the line grows past the marks or the gap widens over a few months, the crack is active, and active cracks are the ones that point to movement underneath.
Together, those two signs usually mean part of the foundation has moved, not that the drywall is simply old. When a section of the footing settles, the framing above it twists slightly, so door frames go out of square and doors rub, swing open or will not latch, while cracks open at the corners of doors and windows where the wall is weakest. HomeGuide's July 2025 foundation crack repair guide lists cracks accompanied by doors or windows that will not close among the warning signs that need prompt professional evaluation, along with cracks wider than 1/8 inch. Check whether the cracks run diagonally from door corners, whether floors slope toward the same side, and whether brick outside shows stair step cracks. If several line up, the house needs level readings, which BDry Alabama takes every five feet with its digital foundation scan.
For a crack that is not threatening the structure, typically $250 to $800 per crack, according to HomeGuide's July 2025 foundation crack repair guide. That covers professional injection, where epoxy or polyurethane is pumped into the crack under pressure so it fills the full depth of the wall rather than just the surface. The price goes up when the crack is a symptom: HomeGuide puts minor structural crack repairs at $1,000 to $5,000 or more and major ones tied to foundation failure at $10,000 to $30,000 or more, because the cost then is in piers, wall reinforcement or drainage, not the crack itself. Several small cracks on the same wall are often handled in one visit. BDry Alabama publishes no chart price; the free inspection identifies which kind of crack you have and ends with one written number.
It depends on whether the crack is still moving and whether it leaks. HomeGuide's July 2025 guide explains that epoxy works best for stable, non moving cracks, hardening to become stronger than the surrounding concrete for a permanent structural repair. Polyurethane stays flexible after curing, which suits cracks that open and close with the seasons and cracks that let water in. Both are injected, and both typically fall in the $250 to $800 per crack range. In clay soil that swells through a wet March, which NOAA's 1991 to 2020 normals put at 5.66 inches of rain at the Birmingham airport station, and shrinks by fall, many basement cracks move a little every year, which is where a flexible seal earns its keep. BDry Alabama uses both, choosing epoxy for structural bonding and polyurethane for flexible waterproof sealing.
Direction, width and movement are the three things to read. Horizontal cracks across a basement wall are the most concerning, because they usually mean soil outside is pushing the wall inward. Stair step cracks along the mortar joints of block or brick point to settlement or uneven stress. Vertical and diagonal hairline cracks in poured concrete are common and often come from shrinkage as the concrete cured. HomeGuide's July 2025 guide treats horizontal cracks longer than 12 inches, cracks wider than 1/8 inch, cracks with water coming through, and several new cracks appearing at once as signs that need prompt professional attention. A crack that comes back after it has been patched is also telling you the cause is still there. BDry Alabama measures each crack's size, direction and activity before calling it cosmetic or structural.
Often, yes. Concrete shrinks as it cures, and thin vertical hairline cracks in a poured foundation are common, especially in newer homes, without any problem in the soil. HomeGuide's July 2025 guide calls cracks under 1/8 inch often cosmetic, but it still recommends monitoring and sealing them, and suggests dealing with hairline cracks within a year so water does not start using them. The easy check is to mark each end with a pencil and date it, then look again after a wet season and a dry one. If the crack stays inside the marks and stays dry, it is likely stable. If it grows, widens, or shows a damp streak after rain, it is active, and an active crack, even a thin one, is worth having measured.
Because saturated soil outside the wall is pushing water through the path of least resistance. That pressure, called hydrostatic pressure, builds fastest on heavy rain days, and NOAA's 1991 to 2020 normals give the Birmingham airport station 17.7 days a year with an inch of rain or more. Damp streaks or active dripping through a crack after rain mean groundwater has found a way in. Polyurethane injection seals the crack through the full wall thickness and stays flexible, and HomeGuide's July 2025 guide puts injection at $250 to $800 per crack. If water pressure outside is the real driver, though, short downspouts, poor grading or a high water table may need correcting too, or the water will look for the next weak spot. BDry Alabama checks the drainage at the same visit.
You can seal a small, dry, cosmetic crack yourself, but there are two catches. Store bought patching compound on the surface does not fill the crack through the thickness of the wall, so water under pressure often comes back around it, and a patch can hide a crack that is still moving. If you have patched the same crack before and it reopened, the cause underneath has not been addressed. Professional injection, which HomeGuide's July 2025 guide prices at $250 to $800 per crack, pumps epoxy or polyurethane into the full depth of the crack under pressure. Before patching anything, mark the ends and date them so you can tell whether it is growing. A horizontal crack, a stair step crack or one wider than 1/8 inch should be looked at before it is covered up.
It depends on the type. HomeGuide's July 2025 foundation crack repair guide says horizontal cracks require immediate attention, vertical cracks should be repaired within 6 months or sooner, and hairline cracks can wait but should be addressed within a year to keep water out. Cracks that leak move up the list, because water that sits against framing, drywall or stored belongings causes damage on its own, and the EPA notes that materials dried within 24 to 48 hours usually will not grow mold, so water that sits longer is the real risk. A crack paired with doors that will not close or a floor that has started to slope also should not wait. Early crack repair is usually simpler and cheaper than repairing the larger damage that can follow, and BDry Alabama offers the inspection free so the timing decision is made on facts.
Unrepaired ones can. HomeGuide's July 2025 guide notes that unrepaired foundation issues can reduce a home's value, while properly documented professional repairs often have minimal impact on resale. The word that matters is documented. A buyer's inspector will flag a horizontal or stair step crack, and a fresh patch with no paperwork invites the question of what is being hidden. Keep the written scope, the date of the repair and photos of the crack before and after. If the house was measured, the numbers help too: BDry Alabama's digital foundation scan records level readings every five feet in a color coded report that can support real estate decisions. HomeGuide also reminds homeowners that most insurance policies exclude cracks from settling or soil movement, so the repair is usually paid out of pocket.
Call BDry Alabama at 205 942 1976 or send the form, Monday through Friday from 7 in the morning to 6 in the evening. The inspection is free. A photo of the crack with a coin or ruler beside it helps, along with a note on whether it leaks after rain or has been patched before. At the visit we measure the size, direction and activity of each crack, check the doors, floors and drainage that show whether the house is moving, and tell you plainly whether the crack is cosmetic or structural. You get one written price, with financing options if you want them. For context, HomeGuide's July 2025 guide puts a professional foundation inspection at $400 to $750 nationally.
Yes, most basement wall cracks can be repaired from the inside by injection, with no digging outside. Injection pumps epoxy or polyurethane into the crack under pressure, so the material fills it through the wall instead of coating the surface. HomeGuide's July 2025 foundation crack repair guide prices crack injection at $250 to $800 or more per crack, and says epoxy suits stable cracks while polyurethane stays flexible for cracks that move with the seasons. Carbon fiber strips, at $900 to $2,000 or more per crack, also go on from the inside to keep a cracked or bowing wall from moving further. Inside repair has limits. A horizontal or stair step crack points to soil pressure or settlement, and HomeGuide notes wall anchors, one common fix for that, require significant excavation outside. BDry Alabama checks the size, direction and activity of each crack before choosing between injection, wall reinforcement and other repairs.
