"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

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

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.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.
