"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"Paradigm Home Solutions hit a home run in every respect. Complete waterproofing of a wet 600SF basement with French drains and two new pits with sump pumps. Since then the basement has been completely dry. This was part of a whole house remodel: structural, electric, plumbing, gas, etc. Paradigm stands out as the best contractor we dealt with through this entire project. Bob and Andy answer their phones without fail, their crew showed up on the scheduled days, worked hard (real hard) for 2 days straight in the July heat, and made no shortcuts or excuses. When we had a couple of simple questions a few weeks later Bob picked up the phone immediately. I wish all contractors demonstrated this sort of quality, commitment and communication."

"I'm not fully moved into the home yet, but I will update when I am there permanently. The crew was very professional, worked diligently, cleaned up after every day of work (three day job--french drain expansion, two additional sump pumps installed, window drains into the sump pumps, pretty extensive job)."

"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."

"Drytech contacted me about my inquiry for a drain system in my driveway. We set up a date and time. The company called the day before â to confirm the time. The representative arrived on time. We discussed the issues w/ my driveway, and my concerns. After discussions he told me that I probably did not need a drain system. While he did not complete any work for based (because of his honesty) I was impressed with his questions, the time he spent with me and how pleasant he was. He left me his card and informed me what issues to look for."

"This company was very organized from estimate to installation. The men they sent to complete the job: Caleb Haywood, Christian Garcia and Noah Jones were AWESOME. They worked on our job for a long time and they were professional from the minute they got here to the minute they left. They encapsulated our crawl space and it looks so so good. They cleaned up the yard and everything so well there was not even a tiny piece of material left. We would recommend the company and these installers to anyone which is rare anymore! Great job guys … thank you."

"My basement was getting wet every time it rained.. I called and was able to have an inspector come out right away for a free estimate. Everyone was so nice and very professional. I now have a dry basement! I would highly recommend them if you are in need of any waterproofing or foundation services!"

"Mike just left our house where he installed a new diverter valve, replaced the pipe for the tub drain and put in my new cast iron tub (a whopping 400 lb monster). He was great! A real pleasure to work with. We've been burned quite a few times by various contractors over the past year, so having someone like Michael come in and get the job done without drama or being hassled was a blessing. I am keeping his card for future reference and will be giving his name to friends and family if they need plumbing/heating services- and I hope they do because I would love to give him more work!"

Foundation Drain Installation FAQs, answered by experts

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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.

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.
