"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."

Basement Waterproofing questions, answered by experts

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.
