CertainTeed 5-Star Siding Contractor. Google Guaranteed. 150+ five-star reviews.






Siding a building in Somerville means working in conditions most contractors avoid. Zero lot lines, shared walls, scaffolding three stories up with the next building inches away, and tenants living in the building throughout the project. The siding has to be right — but the logistics have to be right first.

Posted on Curtis MatthewsTrustindex verifies that the original source of the review is Google. Our house in Danvers needed new siding and trim, and this was not an easy project. There were surprises once the old siding came off, but John walked us through everything calmly and professionally. The final result looks incredible and feels built to last.Posted on Joshua DixTrustindex verifies that the original source of the review is Google. Very professional operation. Clear contract, good communication, and high-quality work. Our new roof looks great and the flashing details are far better than what we had before.Posted on Imani YussifTrustindex verifies that the original source of the review is Google. We’re in Marblehead, close to the water, and needed exterior work that could actually stand up to the elements. D&G Exteriors replaced our roof and trim, and the difference in quality compared to previous work on the house is obvious.Posted on Miguel RojasTrustindex verifies that the original source of the review is Google.

We live right on the ocean in Gloucester, and the weather absolutely beats up our house — constant wind, salt spray, storms rolling in off the water. After years of patching things, we finally decided to hire D&G Exteriors for a full roof replacement and some badly needed trim repairs. I’m so glad we did. Working on a house this close to the shoreline is no simple job. The crew had to deal with strong winds almost every day, and once they pulled the old shingles off, we found sections of the roof deck that were softened from years of salt exposure. John didn’t overreact or try to turn it into a huge problem — he showed us the damage, explained what needed to be replaced, and kept everything straightforward and fair. Despite the tough conditions, the team worked cleanly and efficiently. You could tell they were used to handling challenging environments. They installed new CertainTeed shingles, repaired the compromised areas, and replaced all the rotten fascia and trim with PVC so we won’t have to worry about it again. The house looks incredible now — sharper lines, cleaner edges, and a roof that finally feels like it can handle a real coastal storm. The best part was how professional the whole process was. They kept the site tidy even with the wind constantly blowing debris around, communicated every day, and never left us guessing about what was happening next. If you live anywhere near the water and need roofing or exterior work, D&G Exteriors is absolutely the company you want. Five stars, without hesitation.Posted on brian haskinsTrustindex verifies that the original source of the review is Google. We’re in Ipswich, and hired D&G Exteriors to replace our roof and correct a long-standing issue around a valley that had leaked during heavy rain for years. Previous repairs never fully solved it. John identified the problem immediately, reworked the flashing detail, and rebuilt that section properly instead of just patching it again. Since the replacement, we’ve been through multiple hard storms with zero issues. The roof looks great, but more importantly, the problem is finally gone. Very happy with the work and the attention to detail.
Somerville’s buildings are overwhelmingly pre-war — original clapboard, asbestos shingles, early aluminum, and first-generation vinyl that’s past its useful life. Each era left different wall conditions behind. We handle all of them.

Full vinyl siding on a typical single-family runs $40,000–$50,000. Hardie and Everlast composite start around $65,000 and go up with trim scope. Triple-deckers are significantly more due to three stories of wall area, scaffolding requirements, and tenant coordination — expect $80,000+ for a full triple-decker reside with premium materials. Complete projects include removal, sheathing inspection, weather barrier, new siding, and PVC trim.
Vinyl is the most affordable — low maintenance, wide color range, solid performance when installed properly. Hardie fiber cement is more substantial, resists impact, and holds its appearance longer. Everlast composite is our primary premium option — factory-finished, fade-resistant, with strong warranties. In Somerville’s competitive real estate market, many owners investing in a reside choose Hardie or Everlast for the curb appeal and long-term value.
Yes — and in Somerville, that’s the majority of our siding work. Three stories of scaffolding, zero-lot-line access planning, tenant coordination, and maintaining weathertight conditions on an occupied building are all standard. We work section by section, floor by floor, and manage the project so residents can continue living in the building throughout.
Most single-family projects take 2–3 weeks. Triple-deckers take 3–5 weeks depending on building size, material choice, and trim scope. Somerville’s access constraints can add time compared to suburban projects, but we build that into the timeline from the start. Clear schedule at signing.
Yes — and on Somerville’s pre-war buildings, there’s almost always something. When we strip old siding, we inspect every square foot. Rot, water damage, and insect damage get repaired before the weather barrier and new siding go on. The sheathing condition behind a 100-year-old triple-decker is never a guarantee.
We strongly recommend it. Old wood trim on Somerville’s pre-war buildings is typically rotted behind the surface even when it looks acceptable from the street. Cellular PVC won’t rot, doesn’t need painting, and gives the exterior a clean, premium finish. On a triple-decker, new trim across all three floors is what ties the whole project together visually.
Yes. With the old siding off and sheathing exposed, it’s the ideal time for continuous exterior insulation. Somerville’s pre-war buildings have minimal wall insulation, and many triple-deckers have balloon framing that allows air to move freely through the wall cavity. Adding exterior insulation during a reside can make a significant difference in heating and cooling costs across all units.
