We are a family owned business and for over 27 years we have proudly helped countless families with their waterproofing troubles. Whether dealing with a Wet basement, crawl space, or a damaged foundation, waterproofing can be a worrisome problem to most people. Ernest Waterproofing is here to give you and your family an ease of mind when dealing with water damage. Statement from our proud owner: " I believe that a good home is built with trust, love, hard work and dedication. These are traits that have been passed down in my family from generation to generation. I believe that a respectable business is built with the very same foundations. My goal is to expand the longevity of your home and more importantly keep your home safe from water damage. We do this by providing impeccable workmanship and providing an earnest commitment." - Ernest Velasquez

"Ernesto & his team provided great expertise and quality workmanship throughout a French drain and sump pump installation. When a small pool of water appeared in my furnished basement, Ernesto quickly diagnosed the groundwater infiltration issue and started the project inside 2 days. When we found a leaky pipe that was compounding the problem, he had a plumber on-site within hours to support the additional fix, and later on, connected us with quality support for the drywall and painting recovery. The situation could have been a mysterious nightmare, but Ernesto shed light on the problems and solved them in short order."

Ali, who came out to do the original estimate, explained the problem with the old drainage system clearly, which was resulting in moisture in one of the walls of my townhouse.

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
