"Groundwork’s did a great job on our house. Luis G was an amazing Forman with Ken H and Mark P all waterproofed under our house. They worked quickly, efficiently and thoroughly left all areas in tact and clean. Luis communicated very clearly about the all aspects of the job until it was completed."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

Basement Waterproofing questions, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.
