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. John took the time to explain things without talking down to us, which we really appreciated. The siding project went smoothly and the house looks brand new.Posted on Isaiah TuckerTrustindex 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.
Salem properties range from historic colonials to triple-deckers to newer condos — each with different yard sizes, access challenges, and design needs. We handle all of them.

Most composite deck projects in Salem range from $20,000 to $50,000 depending on size, complexity, and materials. A 16′ × 12′ basic composite deck runs $18,000–$28,000. Multi-level decks, integrated features (seating, lighting, drainage systems), and custom railings increase the cost. We provide a detailed quote based on your specific project.
For Salem’s coastal location, composite is the clear winner. Pressure-treated wood rots, warps, and splinters in salt air — most homeowners see significant decay after 8–12 years. Composite decking resists salt corrosion, won’t rot, doesn’t need annual sealing, and lasts 25+ years with minimal maintenance. It costs more upfront but saves thousands in repairs and replacement.
Most composite deck builds take 1–3 weeks depending on size, complexity, and weather. A standard 16′ × 12′ deck typically takes 2 weeks. Multi-level decks or those with extensive custom details may take 3–4 weeks. We give you a realistic timeline during the consultation.
Yes. The City of Salem requires a building permit for any deck. We handle the permit application with the Salem Building Department at City Hall. An inspector will visit during construction to verify proper ledger board attachment, joist spacing, and railing compliance. This is included in the project.
We start by understanding how you plan to use your deck — entertaining, quiet sitting area, outdoor dining, hot tub, kids’ play area. Once we understand your goals, we assess your property — lot size, sun exposure, drainage, access, and the condition of your home’s rim board. You see detailed plans before any construction begins.
We install composite railings (match your decking, zero maintenance), aluminum railings (modern look, lightweight, durable), and cable railings (open feel, great for water views). Each system meets Salem’s building code. We can mix materials to match your aesthetic — railings are detailed during the design phase.
Absolutely. Many Salem properties have small yards, especially in dense neighborhoods and older colonial areas. We use L-shaped decks, multi-level designs, picture-frame borders, integrated seating, and strategic layouts to maximize usable outdoor space. The design phase is where this happens.
We’re a Trex Certified Installer and TimberTech Pro contractor — trained and vetted by the manufacturers. We’re also Google Guaranteed, BBB Accredited with an A+ rating, and NRCA Affiliated. We carry full liability insurance and provide manufacturer warranties on all composite decking materials.
