Lynnfield is a town of well-maintained, higher-value homes — colonials, raised ranches, and split-levels built from the 1950s through the 1990s on generous suburban lots. When the original windows reach end of life, homeowners here expect a replacement that matches the quality of the home — not a quick swap with builder-grade product and caulk over the trim.

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.
Lynnfield homes were built across several decades, which means different window types, frame conditions, and installation needs depending on the era. Homes near Lynnfield Center from the 1950s–60s often have original wood windows with deteriorated sills. Later builds in South Lynnfield typically have aluminum or early vinyl that’s drafty and outdated. We handle all of them.

Most whole-home window replacement projects in Lynnfield range from $25,000 to $65,000+ depending on the number of windows, frame type (vinyl, fiberglass, wood), and whether you need full-frame or insert installation. Individual window replacements typically run $800–$2,500 per opening installed. Homes with rotted frames or non-standard sizes are on the higher end. We provide a detailed written estimate after measuring on site.
It depends on the condition of your existing frames. If the wood frame is solid, square, and dry, an insert window saves time and cost. If the frame shows rot, water damage, or has been patched repeatedly, full-frame replacement is the better long-term investment. Many 1950s–60s Lynnfield homes with original wood windows need full-frame — we inspect every opening and give you an honest recommendation.
We install Andersen, Marvin, and Pella for homeowners who want premium fiberglass or wood-clad options. For high-quality vinyl, we work with Harvey and Mathews Brothers. We help you choose based on your goals — energy performance, aesthetics, maintenance preference, and budget. We bring sample profiles to the consultation so you can see and feel the difference.
Most whole-home window projects take 3–5 days of on-site work depending on the number of openings and whether it’s full-frame or insert installation. Individual window replacements can be completed in a day. We stage materials carefully on Lynnfield’s well-maintained properties and protect landscaping, flooring, and interior spaces throughout the project.
Yes — most Lynnfield homeowners see a noticeable improvement, especially those replacing original single-pane or early double-pane windows from the 1960s–80s. Modern low-E coated, argon-filled double- or triple-pane windows significantly reduce heat loss in winter and heat gain in summer. We select the glass package based on each window’s orientation and exposure for the best performance.
We recommend it in most cases, and most Lynnfield homeowners choose to include trim. If the existing wood casing is rotted, cracked, or deteriorated, we replace it with cellular PVC that won’t rot or need repainting. Clean exterior trim finishes the job properly and protects the window installation from water intrusion at the edges.
Yes. The Town of Lynnfield requires a building permit for window replacements. We handle the permit application, schedule inspections, and make sure everything meets current energy code. You don’t need to coordinate with Town Hall — that’s included in the project.
