"Hired them for a basic residential addition foundation job and they completely screwed up every step of the process. They don’t know how to read plans or pour straight out flat foundations. They don’t pay their subs which is coming back on us now. They won't respond to any communications. A lien has now been filed on the project because of their lack of payment. Shocked at their ineptitude. Very friendly people, but they should not be construction business owners."

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.

Most building departments will require that a certified and licensed foundation repair professional or a structural engineer pull permits for foundation repair, so homeowners usually cannot pull them themselves. This helps ensure that an experienced professional completes all structural work on your home. Minor repairs that are technically DIYable often won’t require permits, but it’s still a good idea to hire a professional to carry out foundation repairs.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

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.
