"I contacted Fausto from Tigasi Insulation to discuss a project in my basement. He arrived on time, and from the beginning, I could tell that he was a professional who takes pride in his work. At the end of the job, Fausto personally asked me to inspect the work that had been completed. I was very impressed with the quality of his work and the excellent job he did. I highly recommend Fausto and Tigasi Insulation to anyone looking for professional and reliable service. Thank you, Fausto, for the great work!"

"When it rained my basement would get 2-3 inches of water. Tim and his team redirected all of the drain pipes (5 in all), reshaped the slope of the land surrounding my house, planted grass seed, and left the yard spotless. Now my basement is drier than Arizona in mid-July. These guys are pros, they finished in a day. It was a pleasure to see these men work! Their price was more than fair. You can't go wrong with DIGGS! Thank you, Tim!"

"Dean and his crew were professional, reliable, extremely neat/clean and went above and beyond, often, to make the sure work was completed to my satisfaction. They did small things not even required to make sure the entire basement area was much more than even expected. The basement has never been so dry in the 40 years I have lived here. I would hire them again in a heartbeat."

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

Basement Waterproofing FAQs, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.
