"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"From initial call for an estimate, home visit with estimator, time frame awaiting service to be done and finally the end result - fantastic.  Attentive appointment maker, knowledgeable estimator, courteous calls to remind of service pending, professional workmanship day of service.  Couldn't have asked for better service.  The best part was our recent rain storms that put our basement to the test 8 months after waterproofing/crack repair.  No water anywhere in the basement.  Thank you Atlas!  We have referred others to your service.

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

"We called Patrick to fix a sewer smell in our basement. After digging out a section of the floor, he found a pipe installed by the previous owner that had never been correctly attached to the sewer main. He and his crew worked on a Friday and Saturday to fix the issue. They jackhammered out the floor, dug up the old pipe and replaced it. Patrick was very attentive and showed me all the steps he was taking, carefully explaining everything that needed to be done. Cleaned up afterward and finished the job without issue. Highly recommended."

"Frank did an amazing job during our plumbing crisis. Our basement sewage ejector pump had burned out, causing a backup of waste. Frank and his brother heroically cleared out the waste and replaced the pump with a model better suited for the job. They were quick, friendly, and transparent through the entire process and their pricing is fair and straightforward. I definitely recommend calling Frank and SewerServ for any plumbing needs."

Basement Waterproofing FAQs, answered by experts

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.
