Foundation Repair questions, answered by experts

Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

It’s usually not an immediate safety risk to live in a house with foundation problems, but you don’t want to let those problems persist. Most foundation issues don’t lead to a house’s sudden collapse, but they can lead to health issues like mold growth and pest intrusion, as well as problems like uneven floors or rotten beams and joists, which can pose injury risks and be costly to fix.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.
