"Had huge foundation problems at a project of mine on the waterfront. We used terrafirma to both waterproof the entire basement AND lift the foundation. 10/10 would recommend. extremely communicative, very knowledgeable, and even brought a crew in from Oregon to help us stay on schedule. Oscar and jorge got the job done extremely quickly and Seth was fantastic as my project manager."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

Basement Waterproofing questions, answered by experts

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, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.
