How we fix it
Our approach
Read the crack
Width, direction and whether the two sides are offset tell us if it is a simple leak or a sign of movement. We explain what we see in plain terms.
Seal it through the wall
The crack is injected so the seal runs the full thickness of the wall, not just the surface you can see.
Reinforce where needed
Cracks that have moved can be reinforced across the face of the wall to help hold the repair.
Fix what fed it
If a downspout or grading is soaking that section of wall, we will point it out and quote the drainage fix alongside the repair.
Common questions
Foundation Crack Repair FAQ
Is every crack a structural problem?
No. Thin vertical cracks in poured walls are common and are often only a water problem. Wide, horizontal or stair-step cracks deserve a closer look. We will tell you which kind you have.
I am buying or selling the house. Can you look at it quickly?
Yes. Tell us it is a real-estate deadline when you request the estimate and include the inspection note if you have it.
Can I just caulk it?
Surface caulk and hydraulic cement tend to let go because the crack keeps moving with the seasons and water still sits inside the wall. A through-wall seal lasts because it fills the crack itself.
