Posted on Bradford JonesTrustindex verifies that the original source of the review is Google. We had been in our home a long time and exterior was due for serious updates. Roof was from the early 90s, siding was peeling in layers, and the windows were old vinyl with seal failure and had no insulation. We kept putting it off until a neighbor recommended John. He spent over an hour walking the property with us on the first visit, pointing out things we hadn't even noticed, including a section where moisture had been getting behind the siding for years. He didn’t pressure us, just a clear explanation of what was going on and what it would take to fix it right. We ended up doing everything. Full roof, new siding, all new windows, and complete trim. The crew showed up early, kept the property clean (and cleaned up after), and communicated well throughout. When they found more damage than expected behind one wall, John called same day with pictures and options before moving forward. The transparency was both refreshing and important. It's been about a year and a half and everything still looks and performs exactly as it should. Heating costs dropped noticeably and was especially apparent this year. We live on a main street and the noise in our front bedrooms is gone. The house legitimately looks like a completely different property. If you're in the north shore area thinking about exterior work, get a quote and talk to John. You'll see the difference.Posted on Roman CooperTrustindex verifies that the original source of the review is Google. We have a big old farmhouse out in Boxford with a roof that probably should've been replaced five years ago. Finally pulled the trigger and called D&G Exteriors. John came out, looked everything over, and gave us a quote that was fair and detailed. Crew did the whole tear off and install in three days. No complaints at all.Posted on Parker SimmonsTrustindex verifies that the original source of the review is Google. I’m so impressed with the service I received.

Many Swampscott homes were built in the early-to-mid 1900s with single-pane or early double-pane windows that are well past their useful life. Upgrading to modern, high-performance windows can dramatically improve comfort, reduce energy costs, and protect your home from moisture damage.

Window replacement costs vary based on window type, frame material, glass package, and the condition of your existing openings. A standard double-hung vinyl replacement might start around $800–$1,200 per window installed, while premium fiberglass or wood windows with full-frame replacement and PVC trim can run $1,500–$3,000+ per opening. We provide detailed quotes after an in-person inspection so you know exactly what you’re getting — no surprises.
It depends on the condition of your existing frames. If your wood frames are rotted, water-damaged, or out of square, full-frame replacement is the right call — it lets us install new flashing, insulate the cavity, and start fresh. If your frames are solid and square, insert (pocket) windows can save cost while still giving you a major performance upgrade. We’ll inspect and recommend the right approach for your situation.
We work with several premium manufacturers and aren’t locked into any single brand. This lets us recommend the right product for your home, budget, and performance goals rather than pushing whatever earns us the highest margin. During your consultation, we’ll walk you through the options and explain the trade-offs in plain language.
Not always, but in Swampscott’s coastal environment, we often recommend it. Wood trim near the ocean deteriorates faster than inland, and if your trim is soft, cracked, or pulling away, it’s smarter to replace it with PVC during the window project than to come back later. We’ll assess your trim condition during the inspection and give you an honest recommendation.
Most whole-home window projects take 2–5 days depending on the number of openings and scope of work. A single window replacement can often be completed in a few hours. Full-frame replacements with trim work take longer than insert replacements. We’ll give you a timeline estimate in your proposal and keep you updated throughout the project.
Significantly, especially if you’re replacing single-pane or early double-pane windows. Modern low-E glass with argon or krypton fills can cut heat loss through your windows by 30–50%. We also insulate the window cavity and properly seal the installation, which eliminates drafts that older windows are known for. Many homeowners notice the difference in comfort immediately — the energy savings follow on your next heating bill.
