"Did a great job, thorough, good cleanup and were careful not to make a mess on our main floor. Came back afterwards to flash the french drain to see if that helped reduce our radon levels. Really nice guys, would highly recommend."

"The representative from Basement Systems showed up right on time and got right to work taking measurements and asking questions about the space where the work was to be done. When he was done, he came back upstairs and presented very detailed drawings of the proposed work, which included a perimeter drainage system with redundant sump pumps in a newly-dug pit, which would feed into a pop-up outlet in the back yard. The sales pitch was similar to the others we had seen, where we were educated on how water gets into the basement, understanding hydrostatic pressure against the home's foundation, and where water wants to go.
A few days after receiving the quote, we asked for him to come back and give us a quote for a gravity-fed system, rather than a sump-pump system. He stopped over within the same day, I believe, and took measurements, and called me at work right from my back yard.
The price for the system was nearly the lowest of any others we had gotten, though we ended up not going with them because they were unwilling to do a gravity-fed system to the back of our property, as it did not have sufficient grading. The system itself seems to have a smaller channel than that of other basement waterproofing solutions, but it seemed like it would be adequate to me.

Customers say: Quality work

"We had a great experience working with James and his team to install a patio in our backyard. James helped us understand the different available materials and methods for installation, and he was transparent about pricing. He even encouraged us to come to the masonry supply store with him to see the stones in person to make sure we liked what we were getting. James and his team also helped us solve some drainage issues in the backyard, repaired our side stairs and replaced the stucco, and fixed some issues with our front walk. Even when unexpected scenarios came up, they were handled thoughtfully and efficiently. Everyone was very friendly and worked really well together. It's very clear James cares a lot about his work, and he wanted us to be happy with the result. Overall everything went faster than I expected and looks beautiful!"

"Willie from G&R Landscaping was very professional, and did an incredible job on my property. His attention to detail was like no other, and his work was exactly as we discussed. He installed a belgium block border on my driveway, and his work was extremely neat and clean. Willie also put top soil/seed in a section on my yard, and cleaned out brush and leaves behind my shed and completed everything perfectly. Willie is very responsive and willing to listen and give advice about anything landscape related. His price is very fair and he keeps the customer in mind throughout the whole job. I would recommend him to anyone."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

"Very prompt service. They came right on time. Explained consequences of clearing drain. They did everything to keep the bathtub and floor clean. I would hire again for plumbing needs! Price was great and they will come back if I experience another clog within the year."

Foundation Drain Installation FAQs, answered by experts

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Whether professional drainage installation is covered by insurance depends on your specific policy and the circumstances. In some cases, homeowners insurance may cover the cost if drainage problems pose a risk to your home's foundation or structural integrity. However, it's essential to review your insurance policy, understand the terms and conditions, and consult with your insurance provider to determine if your particular situation qualifies for coverage. Coverage may vary, so it's crucial to clarify the details with your insurer.
