"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

Foundation Repair questions, answered by experts

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

No, foundation repair is not usually covered by home insurance. Most home insurance companies typically consider foundation repair as part of your home maintenance, so they won’t cover the cost. However, foundation damage is sometimes caused by covered events such as a burst pipe or a house fire. In these cases, repairs may be covered.

Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
