Shannon Gutter Services

Joe Morrissey started Shannon Gutter Service in Watertown in 1997, and he's still the one running it — a small, owner-operated outfit that cleans and installs gutters for homes around the area. Its own site promises the kind of personal touch a bigger company skips, treating every house the way they'd treat their own. Every rating this company has picked up online lands at 5 stars — Google, Angi, and Birdeye's ranking of Watertown gutter companies all agree. That's a real pattern across separate platforms, not a single lucky reviewer, but none of them carry much weight in numbers: two ratings here, six there, not hundreds. The Better Business Bureau lists 29 years in business but hasn't rated it at all, accredited or not. One thing worth asking about directly: a blog post from mid-2026 reports that a worker connected to the company died in a fall from a ladder on a job in Waltham. It isn't a complaint about the gutter work itself, but it's the kind of safety and insurance question worth raising before signing anything. Its Angi profile is also upfront that it doesn't offer warranties or emergency service — a burst gutter at 2 a.m. isn't their call, and don't expect paperwork backing the work afterward. For a small, routine gutter cleaning or installation job in Watertown, the track record — thin as it is — points toward a contractor who shows up and does what he says. Confirm insurance and safety practices given the reported incident, and set expectations on timing and any guarantee before booking.
