"Everything went perfectly and was done in a timely manner. I have no water in my basement and the drain is working well. I greatly appreciated that there was mess left to clean up when they were done."

"Excellent all around experience!!!!!!!! After a series of storms and gradual water soaking our basement carpet several times, I finally called Waterproofing One in April, 2017 after seeing their ad several times on our St. Basil's church bulletin. I spoke initially with the owner-Joe who was helpful and he dispatched Dave Cook who came over within an hour. Dave Cook has been in this business and related utility engineering previously for over 30 years and really knows his stuff. Dave was extremely thorough, spending time in the basement, looking at some pictures I took of the damage and spent a considerable amount of time walking around the exterior of my property and reviewing the landscaping where most problems start. Dave wrote up a report of what work was needed including extending downspouts, recommending we have our contractor add a louvered door at the top of the steps for aeration (a great idea given no windows in basement) , waterproofing the well water closet walls, spraying impacted area for potential mold, and installing a new French drain and sump-pump system with battery backup. Gene and his crew then came over on May 17, 2018 and performed the construction and installation work and did a great job. Those guys worked extremely hard in what is inherently a muddy line of work and were very courteous, professional and left the basement very clean. Gene took extra time to show us exactly what they were doing as they drilled holes into the lower cinder block walls, laying of the perforated pipe and some of the damp mold on the wooded studs he extracted at the impacted area. We paid exactly what Dave originally quoted! Dave Cook came back checked on things and made some other recommendations including adding stones around the foundation outside and in holes to avoid soil erosion and soften the acceleration of rain water into the ground. Once the work was finished and our carpenter redid the walls and painting, We had subsequently refinished the basement with high end vapor/mold resistant padding from Mohawk and a quality polyester carpet. 15 months later and here we are on September 30, 2019 after 50+ rain storms since installation and NO WATER nor Mold issues in the basement!!! We are really enjoying our basement again thanks to WATERPROOFING ONE!!!! 5-STARS!!!!!!!!"

"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"The foreman, Roberto and his crew, Alun and Jose did an excellent job installing push piers to stabilize our foundation. They did a super job of resolving an unexpected problem that was encountered with a footer under a slab portion of the foundation. These men are a valuable asset to your company."

"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)."

"Because of the great service from Best Buy I feel compelled to update my review below. My situation was complicated. A spring runs continuously under our slab, there was water in several places within our finished basement, and there was a leak under a supporting I beam. Best Buy, unlike other companies, warrants the entire floor, not merely the area around their work. This warranty is invaluable as my experience demonstrated. Andrew, the owner, and his crew came out at least 5 times, sometimes on short notice, once on Sunday, to figure out how to solve all of the complicated issues. They had to build a perimeter drain, a lateral drain, and a speed drain and they had to epoxy around the supporting beam. On one occasion I called because there was a damp spot in one place, but Andrew pointed out several others that I'd missed. Of course, it wasn't in his interest to do so as it required more work. I highly recommend Best Buy!"

"$9,500 I was quoted for my concrete driveway and porch to be removed and a new concrete driveway and pad poured. I needed a culvert installed under the foot of my driveway for rain water drainage, it was agreed that a 4" pipe would work. When the crew came out to do the work, the demolition part went very smoothly but when it came to the drain I was told I needed an 8" pipe. The trench was dug for it including digging an 8" deep by 1 foot around hole in my nabors parking pad. Than I was told the grading was wrong. I told him water wasn't draining because the trench he dug for the 8" pipe he suggested was below the rest of the drain lines and the water will not flow untill it was leveled back out. He argued with me about it for about 3 hours wile the concrete was starting to be poured. After his own workers and I told him the 8" pipe would not work, we went back to the originally quoted 4" pipe and everything drained fine. After the concrete was completed the work looked great."

Foundation Drain Installation FAQs, answered by experts

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.

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.

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.
