"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."

"Crawl Space Jam did an incredible job of encapsulating and waterproofing our crawlspace! Throughout the project, Chris Venzon-owner, continued to provide progress reports, before and after photos, and to make us aware of any operation that might create noise (critical as one of us works from home). Chris even went beyond the scope and replaced the door to our crawlspace to ensure everything was sealed well. We would highly recommend Chris and Crawl Space Jam to help you with your crawlspace concerns!"

Basement Waterproofing questions, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

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.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.
