If you notice cracks in walls, doors that stick, or floors that slope, your foundation may be sending a warning. Ignoring it can lead to bigger damage and higher repair bills. Below you’ll find the most useful steps to check, fix, and keep your foundation solid.
Start with a quick walk‑around. Look for horizontal cracks in brickwork, vertical cracks wider than a hairline, and gaps where the sill plate meets the floor. Inside, check for doors that won’t close all the way and floorboards that bounce when you step on them. If you see any of these signs, write them down and measure the cracks with a ruler.
Next, test for moisture. Damp spots on basement walls or a musty smell often mean water is seeping in, which can weaken concrete over time. Use a garden hose to spray the outside wall near the crack; if the moisture spreads inside, you have a drainage issue that needs fixing.
For small vertical cracks, a concrete epoxy filler works well. Clean the crack, apply the epoxy with a putty knife, and smooth it out. Let it cure for the time the product says (usually a few hours) and you’ll have a seal that stops water from entering.
If the floor is sloping, check the soil around the foundation. Adding a few inches of compacted gravel can improve drainage and reduce pressure on the walls. Make sure the ground slopes away from the house at about a 5% grade.
Another quick win is gutter maintenance. Clogged gutters force rainwater down the walls, which can push soil and cause settling. Clean the gutters twice a year and add downspout extensions that carry water at least six feet away from the foundation.
When cracks are wider than a quarter inch or you see bowing walls, it’s time for a more involved repair. Professional options include piering (driving steel piers deep into stable soil) and slab jacking (injecting grout underneath a sunken slab). Both methods restore level and strength but require a specialist.
Before hiring anyone, get at least two written quotes and ask for references. A reputable contractor will inspect the site, explain the cause, and show you a clear plan with costs broken down.
Finally, keep an eye on the fixes. Re‑measure cracks after a month and after heavy rain. If they keep widening, the problem may be deeper, and a structural engineer should evaluate the house.
Fixing foundation issues doesn’t have to be a nightmare. Spot the signs early, tackle the easy fixes yourself, and bring in pros for the big jobs. With these steps you’ll protect your home, avoid costly surprises, and keep the foundation solid for years to come.
