"He had a cancellation and was able to come out the day I called. He verified that we actually didn't have mold growing in the one area. Since that area was connected to an indoor hot tub room, he checked the tub room just to verify that all was ok in there. He gave me some tips on preventing mold in that tub room and informed me about some other areas to watch (as this was in the basement and we have had water get inside with heavy rain) and I asked him about some marks on my basement ceiling. He was very knowledgeable and helpful. Will definitely be calling if need for future services."

Basement Waterproofing FAQs, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
