"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"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!"

"Dean and his crew were professional, reliable, extremely neat/clean and went above and beyond, often, to make the sure work was completed to my satisfaction. They did small things not even required to make sure the entire basement area was much more than even expected. The basement has never been so dry in the 40 years I have lived here. I would hire them again in a heartbeat."

"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

Basement Waterproofing FAQs, answered by experts

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

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.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.
