Foundation Repair: Quick Fixes and When to Call the Pros

If you notice uneven floors, doors that stick, or cracks in walls, your foundation might be sending a warning. Ignoring these signs can lead to bigger problems, but you don’t always need a huge budget to start fixing them. Below are practical steps you can take right now, plus tips on when a professional should take over.

Spot the Signs Early

Walk around the outside of your house and look for vertical cracks in the brick or concrete. Inside, check for hairline cracks around windows and doors, and see if the floor feels spongy in one spot. A simple test is to place a level on the floor; if it tilts more than a millimeter, the slab may be shifting.

Also, pay attention to moisture. Water pooling near the foundation can soak the soil, making it expand and push against the walls. A soggy yard after rain is a red flag.

DIY Repairs You Can Do Today

For small, non‑structural cracks (less than a quarter inch), clean the crack with a brush, apply a concrete repair filler, and smooth it with a putty knife. Let it cure according to the product’s directions—usually 24 hours.

If you have sticking doors, sand the bottom of the door or install a door sweep. This helps reduce pressure on the frame, which can otherwise worsen a crack.

Improving drainage is a cheap but effective fix. Add a slight slope away from the house using soil, or install a French drain if water consistently gathers near the foundation.

When the cracks are wider than a quarter inch, or you see bowing walls, it’s time to call a foundation specialist. These issues usually mean the structure needs reinforcement, which DIY methods can’t safely handle.

Hiring a pro doesn’t have to break the bank. Get three quotes, ask for a written inspection report, and check if the contractor is licensed for foundation work. Many companies offer a free assessment and can suggest the most cost‑effective solution, whether it’s piers, carbon fiber straps, or slab jacking.

Prevent future damage by keeping the ground around your house dry, fixing leaky gutters, and scheduling a professional inspection every few years if you live in an area with expansive soil.

Remember, a solid foundation protects everything else in your home. A little early effort—spotting cracks, cleaning drainage, fixing small gaps—can save you from a costly repair later. Stay observant, act fast, and don’t hesitate to bring in an expert when the damage looks serious.
