"Fausto and his team did an amazing job ripping out old fiberglass and installing new spray in. They also made a custom drywall cover for the exposed pipes. All done in 1.5 days. Less expensive than the comp. Would use again. Great to work with."

"When it rained my basement would get 2-3 inches of water. Tim and his team redirected all of the drain pipes (5 in all), reshaped the slope of the land surrounding my house, planted grass seed, and left the yard spotless. Now my basement is drier than Arizona in mid-July. These guys are pros, they finished in a day. It was a pleasure to see these men work! Their price was more than fair. You can't go wrong with DIGGS! Thank you, Tim!"

"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!!"

"I ve used Newburgh Plumbing and Heating several times for various reasons, usually on rehab projects. Most recently though, I had to call him for a backup at my house, on a Saturday evening, in the snow. I am not kidding. John arrived within the hour and cleared the blockage, and while it was not the cheapest, it was his response time and proficiency that would lead me to recommend NPH to others."

Basement Waterproofing FAQs, answered by experts

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

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.
