"On time. On budget. We had an interesting conversation over their contract but the owner worked with me to come to an equitable modification we could both live with. There was a part of the work bracing joist that was cut out for the toilet drainpipe that was not done correctly. Once I reported it, I was told I was correct and that they would have someone back to fix it correctly. All that happened as they said it would. No big job ever goes perfectly. These folks stood by their sales pitch and took care of everything very professionally"

"We were disappointed to learn that the home we recently purchased had major mold issues in our crawlspace. We learned after several estimates that the crawlspace issue had not been properly addressed, after we noticed significant moldy, musty odors in our bathroom.
An inspection of the crawlspace revealed the need for immediate mold remediation and repair of our space. We contacted and received estimates from four crawlspace companies, and were far and away impressed the most with Crawl Space Doctor, which now has an office/operation in Charlotte (their address still shows as Savannah, GA).
The owner of the company, Greg McBride visited our home, explained their services, and gave us a very competitive estimate for the work. In addition the materials he offered were of higher quality with being priced at either the same or slightly lower price than all other estimates.
Greg also offers a world-class guarantee, and offers an annual recheck of the work at no cost; he also made a minor repair of the crawlspace dehumidifier at no cost to us.
Greg's crew arrived on time, along with Greg, who regularly returned to check in on the work and his crew's progress. His gentlemen worked extra hours, and did a world-class job throughout the job.  Greg periodically checked in with us, to explain the job status/progress, and answered all our questions.  He obviously knows his business, and also joined with his crew in the crawlspace periodically, to check on the work and their progress.
We researched our options carefully, received 4 estimates from leading companies. Greg and Crawl Space Doctor were far and away the most impressive.
We enthusiastically recommend Crawl Space Doctor should you need work in your crawlspace.

"They did a great job. They solved all the problems I had with the chimney and it’s been working perfectly ever since. They also fixed a problem on the roof around the chimney; they replaced the wood around the chimney with a material that would never rot, so they fixed it even better than it was before. It took them a couple of days to do the work. They took care of all the cleanup as well. We've been real happy with them."

Foundation Repair FAQs, answered by experts

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.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.

Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.
