"Would be 5 stars based on the crew, but we had problems with the lead up to the job, which started 3 weeks late based on the salesman not understanding the scope of work and promising something that wasn't possible. The Friday before work was supposed to start, Gustavo (the supervisor) came to look at the job and let me know it would not be able to be accomplished the way we wanted. He worked with the Engineer (Scott) to figure out a way-ahead. Once the plumbers moved some interferences, the crew started. Eduardo (foreman) and his team (Jorge and Hector) did an expert job. They communicated each step of the way, were respectful of the inside of the house, took no shortcuts, and cleaned exceedingly well at the end of each day. These guys were top-notch! The best of the best! We were able to accomplish the first three of our goals: 1. Stabilize the house 2. Gain room in the basement. 3. Get lift to make the house [more] level. 4. Recover the existing beam for use over our fireplace."

"Terrible company. They are not upfront about cost of services and tack on additional fees without informing you. This is a company that is only after the money and hook you into a contract. The product is not even very effective. I have watched them perform the service via my home security system while I have been away and the yard guard is a joke. They casually apply it around the perimeter of your home, but isn't it intended to guard your entire yard? This company is a joke. Never again."

We are a full service basement, crawl space and foundation repair contractor. Rated A+ by the Better Business Bureau we have repaired over 40,000 homes and structures in Virginia, West Virginia, Tennessee, and North Carolina over the past 40 years. We are fully insured and licensed. Angie's List members receive a free consultation and inspection. We have worked in all types of locations, including residential and commercial locations, government agencies, colleges, hospitals, churches, and condo associations. We provide a lifetime transferable warranty, carry a Class A Contractor's License and we're fully insured.

"Should be called "Steal-tite". Company came out to give estimate in MAY 2019. Said they couldn't do the job until December, but we weren't having any leaks by June, so we went ahead and signed contract, sent in $800 deposit. Well, we ended up buying another house and decided not to have the work done. This was about October. Tried to call Seal-tite several times, always get the "answering service" and they never call back. Finally found the card of the engineer who quoted our estimate, Curt Giantonio. He said too bad so sad for our deposit, and that we had no recourse to get the money back. I realize the contract said the deposit was non-refundable. But the company could have been courteous, understood the situation, and refund my deposit even though legally they don't have to. Instead they've chosen to keep my money for zero services rendered. I could understand them keeping a portion to cover the travel costs of the engineer who came on site to give the estimate, but there's no way that is anywhere near $800. Greedy company that obviously doesn't care about people."

Basement Waterproofing questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.
