"They came out & explained how they were going to resolve the drainage issue from our basement & lawn. We were surprised at the depth of work they had done to ensure that this issue was resolved for the new owners. They did as they said they would do per the estimate. These guys worked so hard & got rained on a good bit of the day, yet that didn't stop them from completing the job. They went above & beyond. It has been over a month now & we are very pleased to see no drainage issues. Thanks Waterproofing One for coming to our rescue! Dave & Lisa"

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"Every phase of the basement waterproofing project was first-rate. Through sketches, the inspector/technician took the time to explain how a sub-floor pressure relief system works. In a knowledgeable and professional manner, he designed the system for our basement and presented a detailed project proposal with drawings. An affordable cost estimate was reached. Also, financing guidance was given to obtain a deferred interest loan. Three days later, the construction crew arrived to begin installation of the system. They were attentive to specific concerns and answered all questions completely and politely. Through discipline and hard work, they completed the job in two days, one day ahead of schedule. Upon completion, including a thorough clean-up, a tour was given of the newly installed system. Dry Tech Waterproofing Systems is a high quality and efficient company that I will highly recommend to family, friends, neighbors, and others."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Wilmington, DE

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
