"I rate the job of cleaning our power washing our exterior house (great care to not damage the older painting, but cleaned the grime and dirt), and our walkways and driveways. Jon is a lovely man who was very prompt, estimate the time for the job perfectly, and left our old home and exterior in much better than I thought it might look.

Foundation Repair questions, answered by experts

Yes, you can fix a block foundation. It’s important to address the issue immediately and have a foundation repair professional understand the severity of the issue and determine the best course of action. If the wall collapses before the foundation is repaired, then you’ll have to reassess your entire foundation.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Ensures structural stability and long-term safety of the building.

Most homeowner’s insurance policies will cover the cost of slab leak repair that results from a natural disaster, like an earthquake or a severe flood, or from a tree falling on your home. Damage from frozen pipes in your slab is also typically covered. However, your policy is unlikely to cover the repair if an invading tree root causes the damage or if it’s a pinhole leak that results from corrosion. You should contact your insurance provider for a full run-down of what they cover.

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.
