Foundation Repair questions, answered by experts

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

Yes, foundation problems can cause ceilings to collapse or even your whole house to crumble. Left unaddressed, natural sinking can build up and eventually harm your home’s supporting structure, such as walls, beams, and frames. Your basement ceiling may be the first place to look for signs of a ceiling collapse caused by foundation problems.
