"I highly recommend this contractor. They were highly professional in every way: they always came just when they said they would, they did exactly what they said they would, they were great at solving problems that arose during the basement waterproofing project, and they did a really good job of keeping us informed multiple times a day about the progress of the project. The crew that handled our project was outstanding. We were especially appreciative of the work done by the foreman, Dan. Just great all around work."

"Woodford brothers did a great job waterproofing my basement. There estimate was right on par with other companies and actually a bit lower. The workers were very professional and very respectful of my property and house. Shoutout to Hunter who answered all questions thoroughly and didn’t mind at all how many I had as he was working! They showed up on time and worked all day, barely taking breaks. And so far, and we’ve had a few rainy days, we have had no water in our basement. I would not hesitate to recommend Woodford Brothers."

"Sergiy and his team did a phenomenal job with our basement project. The level of workmanship was outstanding. The team of workers was reliably on time and always courteous and respectful. They handled every little detail of the construction - framing, electric, sheet-rocking, installations, flooring, painting, and more. Also, Sergiy took great care to consult with us about every design consideration, and offered great practical solutions. We highly recommend My Town, and will definitely hire them again for our next project!"

"My rear facade wall was falling apart, there was apparent deterioration, cracks falling apart. I was recommended to High Tech by our community board. Scaffold was used for this project. They chipped out the 4-story facade and applied wire-mash. First coat of cement was for curing and the second coat was  the finishing coat. The finishing coat was very finely re-finished. The back-wall was waterproofed with thoro-coat.  My roof was leaking as well at multiple places, bubbles had been formed with water seeping in, leaving into my kitchen. The weather was very rainy and stormy at that time and thanks to High Tech they repaired my roof by placing a new layer roof on top of the existing roof and stopped the leak. High Tech remains as one of the top recommended company in our community board."

Basement Waterproofing FAQs, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
