Golden Group has installed replacement windows across MetroWest, Greater Boston and Central Massachusetts since 2013. We install Marvin, ProVia and Pella windows, usually with triple-pane glass, and we recommend full-frame replacement because it is the most reliable way to insulate and waterproof the opening. Our own crews do every installation, and each one carries a 10-year workmanship warranty.

When repair makes more sense. Not every tired window needs replacing. A single fogged glass unit can often be replaced on its own, and broken sash cords can be restrung. Original wood windows in good shape, especially in a historic district, can sometimes be restored and paired with storm windows. We don't do standalone window repairs, but if repair is the better answer for your house, we will tell you.
We are not tied to one manufacturer, so we can recommend the window that fits your house and budget. We install three brands:
| Brand | Frame material | Good fit for |
|---|---|---|
 | Ultrex fiberglass, or wood interiors with fiberglass or aluminum-clad exteriors, depending on the line | Wood interiors, dark exterior colors, custom sizes and historic profiles |
 | Vinyl; the Aeris line adds a real-wood interior | Low maintenance and strong energy performance at a lower price |
 | Vinyl, fiberglass or wood, depending on the line | Homeowners who already prefer Pella |
Vinyl or fiberglass? Vinyl is a sensible value choice for many Massachusetts homes and performs well with triple-pane glass. Fiberglass costs more, expands and contracts at nearly the same rate as glass, and is the usual pick for dark exterior colors; if you want dark vinyl, check what its warranty says about color, in writing. Our guide to frame materials and glass for New England compares them in detail.
Book an AppointmentENERGY STAR rates windows by climate zone, and Mass Save requires the Northern-zone ratings, so those are the numbers for a Massachusetts home. Look for them on the window's NFRC label:
| Rating level | U-factor (lower insulates better) | SHGC (solar heat gain) |
|---|---|---|
| ENERGY STAR 7.0, Northern zone | 0.22 or lower | 0.17 or higher |
| ENERGY STAR Most Efficient, Northern zone (needed for the Mass Save rebate) | 0.20 or lower | 0.20 or higher |
ENERGY STAR also certifies Northern-zone windows at U-factors of 0.23 to 0.26 when the SHGC is higher: 0.35 or more at 0.23 and 0.24, and 0.40 or more at 0.25 and 0.26.
Three checks for any quote, including ours:
Most of our installs use triple-pane glass, which is usually what it takes to reach the Most Efficient level. Whether a specific window qualifies still depends on the exact product and size, so check it against the Mass Save list before you order.
Book an AppointmentWe recommend full-frame replacement for most homes. Taking the old window out down to the rough opening lets us inspect the framing, repair hidden rot, and flash and seal the new window into the wall. That is the most reliable way to insulate the opening and keep water out, and it matters most when new siding is going on at the same time. We also install inserts: when the existing frames are solid, square and dry and no siding work is planned, an insert can be a sound, lower-cost choice.
| Full-frame (what we recommend) | Insert (pocket) | |
|---|---|---|
| What comes out | The whole window and its trim, down to the rough opening | Old sashes, stops and parting beads; the original frame, sill and trim stay |
| Hidden rot | Found and repaired | Can stay hidden behind the new window |
| Flashing and air sealing | New, tied into the wall's weather barrier | Limited to the joint between old frame and new window |
| Glass area | Same as today, and you can change size or style | Slightly smaller, because a new frame sits inside the old one |
| Cost and time | More | Less |
We check every frame first and tell you which method fits each window. The full comparison, including how much glass an insert gives up, is in Full-Frame vs. Insert Window Replacement.
Our own crew installs every window to the manufacturer's instructions. On a full-frame job:
Take it down to the opening. We remove the old window and trim and check the framing for rot. In pre-1978 homes, this happens under lead-safe containment.
Repair and prepare. We fix any damaged framing, make the opening square and level, and protect the sill so any water drains out.
Set and flash. We set the new window and flash it into the wall's weather barrier, so water is directed out instead of in.
Insulate and seal. We fill the gap around the window with insulating foam and air-seal it to stop drafts.
Finish and walk through. We install the trim, test every window with you, and clean up.
On an insert job, the old frame stays: we remove the sashes, check the frame, set the new window inside it, and insulate and seal the joint.
Every house is different, so we price each job after a free in-home visit and give you a written quote. What drives the price:
For a regional benchmark, the 2025 Cost vs Value Report puts the average New England window replacement project at $21,922 for vinyl and $27,226 for wood, with 71.2 and 69.7 percent of the cost recouped at resale.
Rebates in 2026. The federal 25C window tax credit ended December 31, 2025. Mass Save pays $75 per window when you replace single-pane windows with ENERGY STAR Most Efficient windows bought in 2026. You apply to Mass Save directly. Your existing windows must be verified during a Mass Save Home Energy Assessment before installation (an older rebate form said before purchase, so schedule it before you order), and you must complete the weatherization the assessment recommends. Applications for 2026 purchases are due February 28, 2027. Details: our Massachusetts window rebate and tax credit guide.

Most of our window work happens alongside a siding project, and that is the best time to do it. Each new window is flashed and lapped into the new weather barrier, instead of being sealed against old housewrap no one can see, and one crew, one permit and one schedule cover the whole wall. We also do window-only projects. See our siding options and roofing.
Workmanship: 10 years. Our installation is covered for 10 years.
Product: from the manufacturer. Marvin, ProVia and Pella each warranty their own windows, and terms vary by brand and product line. Ask us for the warranty that covers the exact windows in your quote.
Most of our window work happens alongside siding projects. A few recent exterior projects from around Massachusetts:

We would rather point you to the right company than sell you the wrong job. Here is where we draw the line.
For repairs, a window repair specialist will serve you better.
It depends on the brand, glass, size, installation method and the condition of the openings, so we price each job after a free in-home visit. For a regional benchmark, the 2025 Cost vs Value Report puts the average New England project at $21,922 for vinyl windows and $27,226 for wood. Full-frame installation and triple-pane glass both add cost.
Installation is quick: a recent whole-house job took our crew three days. Before that, allow several weeks for custom windows to be built after you sign.
Both. We recommend full-frame for most homes, because removing the old window down to the framing lets us find hidden rot and flash the new window into the wall. When the existing frames are solid and no siding work is planned, an insert can be a sound, lower-cost choice, and we install those too.
Generally, yes. State guidance lists a building permit and a Construction Supervisor License for window replacement, plus Home Improvement Contractor registration for work on owner-occupied homes of one to four units. We pull the permit as part of the job.
There is no federal credit: the 25C window tax credit ended December 31, 2025. Mass Save pays $75 per window when you replace single-pane windows with ENERGY STAR Most Efficient windows bought in 2026, with your existing windows verified during a Home Energy Assessment before installation; schedule it before you order. You apply to Mass Save directly, and applications are due February 28, 2027.
Look for a whole-window U-factor of 0.22 or lower, the ENERGY STAR 7.0 Northern-zone level. For the Mass Save rebate you need ENERGY STAR Most Efficient: 0.20 or lower, with an SHGC of 0.20 or higher, which usually means triple-pane glass.
Yes. Assume lead paint until a test says otherwise. A contractor replacing windows in a pre-1978 Massachusetts home must hold a state Lead-Safe Renovation Contractor license and follow lead-safe containment and cleanup; EPA certification alone does not count here. Golden Group holds that license.
Marvin, ProVia and Pella. ProVia windows are vinyl, Marvin offers fiberglass and wood, and Pella offers vinyl, fiberglass and wood. We are not tied to one manufacturer, so we recommend what fits your house and budget.
No. Our own crews install every window.
Our installation carries a 10-year workmanship warranty. The window itself is covered by its manufacturer's warranty, which varies by brand and product line.
Not by us. We don't install windows in winter, the same as our siding and roofing work. Most of our window projects go in alongside new siding, so we schedule them for the building season. A winter consultation means your quote is ready before the season starts.
Yes, and that is the best time to do it. Each new window is flashed straight into the new weather barrier, and one crew, one permit and one schedule cover the wall.
