"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!"

"Integrity waterproofed the roof of my floating house to create large deck space and some months later waterproofed the new decks around my house, both times using an epoxy based product called Deck 70. They are easy to work with, very pleasant to have around the house, and do top quality work. I cannot praise them highly enough. Top notch people doing top notch work."

"The company called us the day after the earthquake, offering to come and do a free check in the crawlspace to be sure there is no damage or places needing repair in the liner after the quake. I phoned them yesterday to make the appointment and they came out today. And there is no damage or repairs needed, and the liner held up, still attached to the foundation cement stones and pillars. I felt this was very thoughtful of them to remember us. Since we installed the product a year ago, they have helped us feel comfortable that the product is doing what it is supposed to do. They also came out during the rains (however brief) in late February and checked that everything was still dry (not that we had flooding or ground water tables rise, but we were concerned that rain might have been coming in from the side vents in the house siding to the crawlspace). It was dry and everything looked good, so we determined that no more work was necessary to close up the house's side vents. That was money and time saved. ...Professional company and good people.

Basement Waterproofing FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.
