I originally hired Basement Waterproofing, Inc (BW) back in the Spring of 2010. I absolutely LOVED their work, but was not an Angie's List member back then. However, a couple months ago (almost three years later), I called BW to see if they would cover a minor issue under their warranty. Being so minor, I was skeptical they would do it. However they came to my house within the week, and fixed the problem at no cost. For this, they are getting an excellent review, as they deserve. The primary reason I hired this company was their warranty. Not only is it "lifelong," but the warranty is transferrable to future owners! (This will be a selling point when I put my house up for sale, and may help me get some of my money back.) BW was the only company to offer me any warranty, and this one was transferrable, too. Sure enough, three years later I got to test this warranty, and now know that they stand behind it. My original problem, back in 2010, was that I had water seeping into my basement through the walls and floor. I was getting small puddles all over my basement, and eventually started getting mold. As soon as I saw a strange mushroom ( !!) growing in my basement, I called in some contractors. Upon further inspection, my wife and I also discovered that at least $500 worth of our belongings were even destroyed by unseen water seeping through the floor and walls they sat against. I called three contractors. Two wanted to dig up my yard, including the front, to refinish/waterproof the exterior of the basement walls. Not only would this mess have destroyed my landscaping, but it was almost ten thousand dollars! And despite all of this cost, they could not guarantee that my basement would be dry! (In fact, it wouldn't be, as part of the problem was UNDER the basement floor, too - a fact that only BW discovered.) BW did these "injections" into the ground around the exterior of my basement, that keeps water away from the walls. No mess!! They also created an internal drainage system to deal with the water from under the basement floor (a problem that would NOT have been addressed by the $8-9000 work with the other contractors). My basement has been bone-dry ever since, and I only payed around $3500. BW is a knowledgable company that did great work, and saved me a lot of money and headaches. I couldn't be more satisfied.
