"If you want to have your foundation waterproofing job done the right way, then I recommend that you have Dani and Sealtech Waterproofing take care of the project for you. They are extremely honest, hardworking, skilled and professional. When I had their work inspected by the County Building Department, the inspector termed their quality of work as "outstanding". After waterproofing I also had them backfill the foundation which was also performed to the same high standards. Everything was completed at a cost that was more than fair. I first contacted Sealtech because of the good reviews I had read about them, but now I'm happy to make the same kind of recommendation based on my own personal experience."

"I will start by saying that the work they did waterproofing our basement looks good, and I am hopeful that it has fixed our problem. We've had a good bit of rain recently, and so far, so good. That, of course, is the most important thing. That said, I chose this company, even though they were on the high range of the quotes I received, because I did not mind paying more for a professional experience and great customer service. I was disappointed with this aspect of the experience. The day they were scheduled to begin they never showed up, and I ended up calling them three times that day. The woman in the office was responsive, but she said that they did not know where they were. The next scheduled appointment was for the morning, and they did not end up coming until 2pm, again without any communication. Both instances were due to car issues, but a phone call to keep me updated would have been appreciated to allow me to better plan my day. When they did start the work the crew leader was friendly and appeared to know what he was doing, but he offered little information about the job unless I asked. Prior to the work being done, I also had to keep after the sales representative to put their warranty in writing. Twice he promised to email it to me, and only after contacting him a third time did he send it through. If I had not paid so much (over $11,000) I would have given them another star, but at this price point my expectations were high."

"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

Basement Waterproofing questions, answered by experts

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.
