Len Gibely Contracting is a North Shore Massachusetts exterior-improvement contractor working on roofing, siding, carpentry, windows and doors, gutters, and decks, based in Peabody and self-reported as serving property owners since 1972. The company holds an active, registry-verified Massachusetts home-improvement-contractor license and carries a BBB A+ grade. Owner Brian Dobbins is named and credited individually across dozens of reviews from 2017 through 2026, and a recurring, specific pattern stands out: several reviews describe the company being called in to fix problems a previous contractor left behind, including a rubber roof that had been poorly installed and was leaking, siding and trim that failed due to earlier substandard work, and roof board rot that other companies had missed during their own inspections. Some customers describe using the company repeatedly over a decade or longer, and reviews consistently note thorough daily cleanup, including crews sweeping driveways for stray nails and screws. Aggregate scores are outstanding: a BBB A+ grade, 5.0 stars on Google from 150 ratings, 4.9 stars on HomeAdvisor from 230 ratings, and 5.0 stars on both Houzz and BuildZoom. There's little of substance to flag — recent activity shows 24 reviews in the last six months with none negative, consistent with the broader history. For roof replacement and repair, window and siding replacement, deck building, and general exterior carpentry on the North Shore, the reviews describe a licensed, long-established, owner-led operation with an unusually deep and consistent track record.
We had a great experience with Len Gibely and with Brian Dobbins right from the get go. We had a huge bay window that needed replacement. The old window was constructed as a bay window but was put together from 3 parts. Now we actually have a real humungous bay window. Carpenters that work there are amazing, just a different level, from covering everything inside and outside to how they worked and cleanup just a pleasure to see. Ended up we had rotted siding around the window as well and we got that replaced as well. Overall price was very reasonable and it was done quickly. The teamwork there I have never seen before from cleanup crews to carpenters to siding and roofing is like I said a whole different level. We will definitely hire them again.
Had a great experience from roof quote to completion of roof replacement. Everyone I interfaced with was informative, responsive and professional. The crew on-site were productive and considerate with my concern regarding landscape. Little details regarding ice dam concerns were addressed and had the chimney re flashed which looks awesome. No damage to plantings and clean up was excellent. I am happy to recommend Len Gibley for your project.

Len Gibley Contracting recently completed a full renovation of the exterior shell of the house and detached barn. We replaced the siding, trim windows, roof, rebuilt the sill, some framing and constructed a new deck. All low maintenance materials, including Azek Trim, Hardie Board siding, metal roof, composite deck and railings. Brian and his crews were professional and courteous. All communication and responses to questions were timely and helpful. I can recommend them without hesitation.
