Customers say: Quick response

"Marc and his team did an amazing job waterproofing our foundation and installing new foundation drainage for our home. It was a huge task, including the removal of an existing deck, which they then rebuilt better than it was before, and the removal of an existing retaining wall, which was beautifully rebuilt with stone. Marc took the time to explain the process and answer our questions. He and his team were out there working hard every day until the job was complete. Our basement is now dry, and we feel confident that it will stay that way. Thank you!"

"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

Basement Waterproofing FAQs, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

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.
