"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"Contacted Mark within 3 days he was at my home and providing a detailed quote. Might seem small but he was the only one out of 4 contractors who actually measured the space to provide an accurate and detailed estimate. He while discussing what I wanted with me made many recommendations and even mentioned ways to get the job done but at a lower cost. He had the estimate to me within 2 days and it was super detailed and broken down with 3 different ways to complete it. He was on time daily as was his crew. Work areas were cleaned daily. He closed up a broken window for us, redid a dirt floor with drainage and concrete, repointed and waterproofed our basement foundation, ripped out and fully replaced basement access stairs. He even noticed a window that was broken we didn’t and closed it up for no charge. He added a drain to the exterior steps at no charge wasn’t in contract he just knew it was needed, the steps he replaced had asphalt around them and he even repaired the asphalt at no c"

"I contacted John as I have a fair amount of water coming in my basement. He promptly came out for a visual inspection and set up a time to do a physical inspection while he was with us. His team worked quickly and efficiently. Once they dug down to the bottom of the foundation, John was able to explain the issues at hand to me and work within my budget to get the job done to the best of their ability. His team worked quickly and cleaned up their site better than it was when they found it."

"DryZone Basements kept me up to date on my Appointment, called the morning of, arrived on time, checked in with me at the beginning to review scope of work, set up a dust barrier, two (2) workers and the job lead, worked hard throughout the time here. The lead would check in with me in intervals, they were open to answering any questions. Upon finishing, the lead took me around the whole job, explained the work, and allowed me to ask any questions, and provided me responses, and cleaned up the work area very well. Hopefully, we will never have to use, but definitely worth the piece of mind. Thank you."

"Dave was extremely helpful and super nice (and patient). We had some delays in our overall project and he continue to connect with me via phone and check in. The work in the basement was done quickly and neatly. I am so impressed with the Watchman team from Doreen in the office, Dave and the person who did the installation. You will not be disappointed with Watchman!!!"

"I highly recommend Custom Coating. My mahogany deck hasn t looked so good since it was installed over 15 years ago; they power washed, sanded and stained it back to looking new. The only drawback was this high heat and humidity which made drying process slow. I would have them come for maintenance next time but in early spring."

Basement Waterproofing FAQs, answered by experts

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
