Basement waterproofing and foundation repair company. Family operated since 1957 with over 500,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.
"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"Handymanny's window well crew in Colorado -was super nice and professional. They arrived on time and were ready to start working immediately. I took them around the property to show them the windows I wanted done and there was dog poop in my yard. I told them I would pick it up asap. They offered to do it but I didn't let them. I couldn't believe they offered to do it. Thats some great customer service. I had to go and left a check for them with my son, but they worked with me on a last-minute addition and when I returned, the job was well done and as I expected. My son stood on it and it was very strong. These egress window well covers will help protect my window ell from filling up with water during rain and hail storms. I highly recommend this company. I will be calling them back to do one more window well in the future."
