SNJ Seamless Rain Gutters is a seamless gutter installer that says it has been in business 20 years and backs its installations with a 5-year workmanship warranty. It holds a 4.7-star Google rating from 47 ratings. A homeowner who hired SNJ recently said Steve gave an estimate within 48 hours, the crew installed the gutters in early spring, and Steve stopped by later to advise on water flow behind the house. A recent customer said two installers handled a 140-year-old farmhouse with many roof angles in Dalton, New Hampshire, at a price they were happy with. A recent customer said the company came back and repaired a section of gutter the homeowners had damaged themselves. A recent customer gave 1 star, saying they were quoted in the spring, told to expect a one-to-two-month wait, and still had no gutters by mid-October after repeated rescheduling. In a 2025 review, a customer said they paid $4,100 for a June 2023 installation, a downspout fell several months later, and Steve twice said he would come make repairs but never showed. In a 2024 review, a customer said an installation was cancelled on the day twice and then became a no-show. In a 2025 review, a homeowner said Steve dug up old drainage pipes to address water seeping into their basement. In a 2025 review, a homeowner said the crew installed gutters and wrapped their fascia and followed up afterwards. In a 2023 review, a homeowner said Steve and his crew stayed late to finish gutters along challenging old eaves, which stopped splashback on the siding and water in the cellar.
I had an extremely frustrating experience with SNJ Gutters. I was quoted in the spring and told to expect a 1–2 month wait. It’s now mid-October, and I still don’t have gutters installed. After an initial installation attempt, I addressed the additional fascia work they identified, but they’ve continued to reschedule without following through. After months of delays and repeated cancellations, I cannot recommend them. I hope others have a better experience than I did.
Seamless gutter install on the front of the house look great and professionally done! Great communication from start to finish. I highly recommend SNJ and I will be hiring SNJ in the future to install on the back of the house!
I will recommend them time and time again! They came out and had our gutters done very quickly. They did an amazing job. So well, that our neighbors even had theirs done by this same company. We ended up damaging a small section of the gutter near our driveway (our fault) and they came out and repaired it for us. Awesome guys, awesome service.
Steve and SNJ Gutters are a responsive, professional, quality-forward operation. I contacted SNJ last fall, and they provided an estimate to install gutters around our home within 48 hours. We agreed on price at that time and they arrived in early spring to install the gutters. High quality materials and professional installation. When we had a follow up question/advice on water flow on the backside of the house, Steve stopped by to provide insight and guidance. Best of all the gutters—once installed—give a polished, finished look to the house. Five stars. Highly recommend. Thanks Steve!!!
SNJ Seamless did an excellent job on my house in Dalton, NH. Two clever guys showed up and took care of a 140 year old farmhouse with a lot of weird roof angles. I was also happy with the price.
