"This was a very involved plaster repair and remediation job, in a very old house. Grady is the only person (or company) who was willing to take on the job and drive all the way from Pennsylvania to our home in Northern Virginia. There are very few people who do this kind of work anymore (we really searched) and he is an expert in his field. We needed to work around his schedule, because he is in demand in the tri-state area, so it took awhile to schedule the work to begin... but it was worth it."

"Ryan proved to be a professional in every way. His gave a fair and what I felt was an on-point quote and was here when he said he would be. My front porch was cracked, caving in and separating from the house, so the present slab had to be removed and the railings around the porch as well. He was through and completely in tune with what we discussed. The whole job was done and complete in 5 days- that included curing and set up time with cement drying. Yes, I would use Ryan again and we are already discussing the next project. I found Ryan on Angi website and I am very happy he was available to do the project. Thank you Ryan!!!!"

Foundation Repair FAQs, answered by experts

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.

Yes. Foundation walls are always load-bearing.

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.
