Foundation Fix: What Every Homeowner Should Know

Noticed a crack in the wall or a sagging floor? Those are the tell‑tale signs that your foundation might need attention. Ignoring the problem can cost you more down the road, but you don’t always have to call a contractor the first time. Below you’ll find easy steps to spot trouble, decide if a DIY fix will do, and know when it’s time to bring in a professional.

Spotting Problem Areas Early

First, walk around the outside of your house. Look for gaps between the brick and the ground, leaning chimneys, or water pooling near the foundation. Inside, check for doors that stick, windows that won’t stay open, or walls that develop hairline cracks at ceiling level. Those cracks often start small but can widen if moisture gets in.

One simple test is the “penny test.” Place a penny on the floor; if it rolls toward a crack, water is probably seeping in. Also, run a level on the floor. If it tilts more than 1/8 inch over a six‑foot span, the slab may be shifting.

DIY vs Professional Fixes

For hairline cracks that don’t move, a DIY epoxy injection works well. Clean the crack, apply a low‑viscosity epoxy, and let it cure for 24 hours. This seals the gap and stops water from entering. You can buy epoxy kits at most hardware stores for under £30.

If you find larger cracks (over 1/4 inch) or notice the foundation settling, bring in a structural engineer. They’ll assess soil type, drainage, and load‑bearing walls. Professional solutions might include underpinning, pier installation, or installing a French drain to reroute water away.

When it comes to cost, DIY fixes usually run between £20 and £150, depending on materials. Professional repairs can start at £1,500 for simple pier work and go up to £10,000 for extensive underpinning. Getting a few quotes and comparing them with a clear scope of work saves you from surprise fees.

Before you start any work, check local building regulations. Some areas require a permit for foundation alterations, especially if you’re adding piers or altering load‑bearing walls. Skipping this step can lead to fines or having to undo the work later.

Finally, maintain good drainage around your house. Keep gutters clean, slope the soil away from the foundation by at least one inch per foot, and consider a gravel strip at the base of the wall. Good drainage reduces the pressure that pushes against the foundation and keeps future cracks at bay.

In short, watch for cracks, test for moisture, and decide quickly whether a simple seal or a professional overhaul is needed. Acting early keeps repair costs low and protects the safety of your home.
