"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."

"It was great luck that Jason of J Drains was working on a job near my home and was able to come by after he finished that job to check my hot water heater. He fixed it right away because he spotted what was wrong quickly. Jason was very professional and polite. I recommend this company!"

Basement Waterproofing questions, answered by experts

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.
