"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"These guys are excellent! Kyle originally came to fix a shower pipe and garbage disposal. We ended up needing more immediate assistance with our water heart & boiler and he was able fit us in to his schedule quickly and did excellent work. The project was more complicated than anticipated, but Kyle and his guys stayed until the job was done to perfection. Cannot thank them enough!"

"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."

"I can't say enough about Watchman Waterproofing and the owner Dave. I got a few estimates for a drain because of water coming into my basement and decided to go with this company based on speaking with the owner Dave (Great Personality) and a fair price. He was very through walking me through each step of the process and didn't try to sell me something I didn't need. I needed to have the work done as soon as possible as I'm in the process of moving and with all the rain we've had and the rest of the week was not looking good with more rain to follow. He told me they were extremely busy and wouldn't be able to squeeze me in for a couple of weeks.The other company could start in a few days and their price matched Watchman by a hundred dollars. The next morning I get a call from Dave and he told me they had a cancellation and could start the work the immediatley I was thrilled! The crew showed up and they were very professional from start to finish. Great Company and fantastic owner!!! Thanks Dave :)"

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

Basement Waterproofing questions, answered by experts

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

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