Foundation Crack Repair in Denver
Poured concrete basement walls across Denver often develop cracks as clay soils swell and shrink with the seasons. Many are shrinkage cracks that only need sealing, while wider, stair-step or horizontal cracks can point to movement. A local foundation repair specialist can tell you which kind you have and whether injection is enough.
Signs you may need this
- Water or damp spots along a basement wall crack after rain or snowmelt
- A crack that is wider at one end or has grown since you first noticed it
- Efflorescence, a white powdery residue, along a crack line
- Diagonal cracks running from basement window corners
- Cracks you want documented and sealed before listing your home
How it usually works
- 1
Evaluate the crack
The contractor measures width, checks for offset and looks for signs of active movement or water.
- 2
Prepare the surface
The crack face is cleaned and injection ports are set along its length.
- 3
Inject the crack
Epoxy is typically used for dry structural cracks, and flexible polyurethane for cracks that leak.
- 4
Cure and finish
After the material cures, the surface seal and ports are removed or ground smooth.
What affects the price
Typical range: $350 - $950 / crack. Your exact price is set after an on-site look.
Number and length of cracks
Most pros price per crack or per foot, often with a minimum charge per visit.
Epoxy vs. polyurethane
The right material depends on whether the crack is dry, leaking or still moving.
Access
Cracks behind drywall, framing or built-ins add removal and patching cost.
Underlying movement
If the wall is moving, the contractor may recommend bracing or piers in addition to sealing.
Questions homeowners ask
Are hairline cracks in a Denver basement normal?
Thin vertical shrinkage cracks are common in poured concrete walls. A pro will look at width, offset and water to decide whether sealing is all that is needed.
Can I seal a foundation crack myself?
DIY kits can work on small dry cracks, but a leaking or widening crack is worth having evaluated, since sealing does not stop movement.
How long does crack injection take?
A typical job is often finished in part of a day, depending on how many cracks there are and how easy they are to reach.
