Noticing cracks in walls or doors that won’t close properly? Those are classic hints that your house’s foundation might be moving. Ignoring them can lead to bigger, costlier problems. Let’s unpack what to look for, quick fixes you can try, and when it’s time to bring in a professional.
First off, walk around your home and check for uneven flooring, bow‑shaped walls, or gaps around windows. Inside, pay attention to doors that stick or windows that jam. Outside, look for soil that has shifted, water pooling near the footing, or cracks in the foundation itself. These clues often appear before any major structural damage occurs, giving you a chance to act early.
If the issue seems minor, start with simple drainage fixes. Make sure gutters direct water at least six feet away from the house and add downspouts where needed. Installing a French drain around the perimeter can also keep moisture away from the footing. For small cracks, clean the area, fill with a polymer‑based sealant, and let it cure. This won’t stop a serious shift, but it can stop water from getting in and worsening the damage.
Another quick win is to level interior floors with self‑levelling compounds. This helps keep furniture stable and reduces stress on the foundation. Just follow the product instructions, spread the mix, and let it set. Remember, these are temporary measures – they buy you time while you plan a longer‑term solution.
If you suspect soil movement, consider a simple soil stabilization technique: compact the soil around the foundation with a hand tamper or a small plate compactor. This works best in dry conditions and when the soil is loosely packed. Again, it’s a stop‑gap, not a permanent fix.
When the cracks are wider than a quarter inch, or you see large gaps forming, DIY stops being safe. Those signs usually mean the structural integrity is compromised and you need a qualified foundation specialist.
Professional foundation repair can vary a lot. Basic piering or slab jacking might start around £1,500, while extensive underpinning can climb above £10,000. Costs depend on soil type, house size, and severity of movement. Get at least three quotes, ask each contractor to explain the method they’ll use, and check for guarantees.
Many insurers won’t cover foundation work unless it’s caused by a sudden event like a burst pipe. That’s why it’s smart to address drainage problems early – it can keep you from paying for large repairs later.
Before signing a contract, verify the company’s credentials. Look for certifications such as the Structural Stabilisation Association (SSA) or equivalent, and ask for references from recent jobs. A reputable pro will also do a thorough assessment, including soil testing and a written report outlining the issue and proposed solution.
After repairs, keep the foundation healthy by monitoring moisture levels. Install a moisture sensor in the crawl space, and keep the ground around your home sloped away at a 5% grade. Regularly clean gutters and check for any new cracks each year, especially after heavy rain or winter freeze‑thaw cycles.
Finally, stay proactive. Small maintenance tasks—like sealing exterior walls, fixing leaky pipes promptly, and avoiding heavy loads on the basement floor—can extend the life of the repair work and keep your home stable for years.
Fixing a foundation isn’t glamorous, but catching issues early and knowing when to call a pro can save you a lot of stress and money. Keep an eye on the signs, try the quick fixes, and don’t hesitate to bring in experts when the problem outgrows DIY solutions.
Fixing a crack in a house foundation can vary in time depending on the size and severity of the crack. Minor fixes might be done in a day, while more severe cracks can require weeks of attention and careful work. It's crucial to consider the right repair methods and the expertise of the professionals involved. Safety and ensuring the integrity of the house are top priorities. With thorough assessment and planning, foundation repair can be managed efficiently.
