Gutter Giant is a family-owned seamless gutter company based in Manchester, New Hampshire, run by owner James Haley since 2021. We install, repair, guard, and maintain gutters for homes and businesses across New Hampshire, Southern Maine, and Massachusetts.
We are not a national chain and not a side gig. Gutters are what we do, and we hold a 5.0 rating from 120 Google reviews from the neighbors who have had us on their roof.
Who we are
Gutter Giant started in 2021 with a simple idea: do gutters right, treat people straight, and stand behind the work. We are family-owned and run out of Manchester, so when you call, you are talking to the people whose name is on the truck, not a call center three states away. That is the whole difference. We live where we work, and our reputation is the neighborhood we work in.
What we stand for
Every gutter company will tell you they are honest. Here is what that actually looks like on a job with us.
| Our commitment | What it means on your job |
|---|---|
| Repair before replace | If a repair will do it, we say so, instead of selling you a new system. |
| An honest quote | A firm, written price after we see the roof, with no surprise add-ons. |
| Done in a day | Most homes are finished, cleaned up, and back to normal the same day. |
| Backed for life | Our installs are warranted for as long as you own the home. |
| We answer | You reach the people who did the work, not a ticket queue. |

What we do
Gutters are the whole business, start to finish. We handle seamless installation, micro-mesh gutter guards, repair and replacement, cleaning and maintenance, downspouts, fascia and soffit, and commercial work. If it has to do with keeping water off your house, it is what we do all day.
Where we work
We are a New Hampshire company first. From Manchester we cover the state and reach into Southern Maine and Massachusetts. We know what a New England winter does to a gutter, because we live through the same one, and we size and install for it.
