Durable aluminum gutters, downspouts, & gutter guards in Andover

Creating a dry, secure property starts with having the best gutter system. If you have leaky gutters that easily clog or sag under heavy loads, then the water that spills over can ruin roofing, siding, landscaping, and even seep into the home or building through the foundation. That is why Thrasher offers the Gutter Shutter system, guaranteed to never clog, sag, or pull away.

Carrie S. hated that her driveway had created a nasty bump due to settling concrete. She had to drive her car each time over the bump and was looking for a driveway repair solution that didn’t require replacing the whole driveway or have mismatching pieces of concrete. She saw a Thrasher advertisement and decided to give us a call.

System Design Specialist Austin Ure went out to the home to see what we could do to fix the problem. We were able to stabilize the concrete by using PolyLevel and NexusPro to lift the concrete back up flush to the garage. Carrie was not only impressed with the work, but the crew that came out to her home was friendly, professional and completed the project on time!
