When most people think of Giannini Roofing, they think of expert roof installations and trusted local service across the South Shore. But what many homeowners don’t realize is that Giannini Roofing & Siding also brings that same high level of craftsmanship, honesty, and family-rooted care to window installations and repairs. Whether you’re looking to improve energy efficiency, enhance curb appeal, or finally replace drafty, outdated windows, Giannini is the name you can trust for exceptional window solutions in Whitman, Abington, Rockland, Cohasset, and surrounding areas.
More Than Just Roofing—A Complete Exterior Solution
Your windows play a crucial role in the look, comfort, and performance of your home. At Giannini, we understand that high-quality windows are more than just a cosmetic upgrade. They’re essential to your home’s insulation, natural lighting, weather resistance, and even safety. That’s why our experienced team approaches every window project with the same precision and pride we bring to our roofing jobs.
As a family-owned and operated business with over 20 years of experience, Giannini Roofing & Siding offers a full range of residential window services—from full replacements to targeted repairs, weatherproofing, and custom installations. And because we’re based right here in the South Shore, we know exactly how to prepare your home for the unique challenges of New England weather.
Energy Efficiency That Pays Off
Let’s face it—heating and cooling costs in Massachusetts can add up fast, especially if your windows are old or poorly sealed. Giannini offers high-performance replacement windows that not only elevate your home’s look but also help reduce your monthly utility bills.
Through strategic upgrades like weatherstripping and advanced sealing, we eliminate drafts, prevent heat loss, and keep your indoor temperature consistent year-round. Our team specializes in installing windows that meet or exceed energy efficiency standards—protecting your investment and improving your home’s long-term performance.
Stylish Options to Fit Every Home
Whether your home leans traditional, coastal, or modern, Giannini offers a variety of window and door options to complement your exterior style:
- Bay & Bow Windows: Choose from classic three-pane bay windows or expansive five-pane bow windows to add depth, light, and architectural interest to your living space. These versatile systems not only increase natural light but also create cozy seating nooks or storage areas inside.
- Front Entry Doors: Looking to refresh your home’s curb appeal? We offer fiberglass, steel, and wood entry doors, customizable with paint or stain options to suit your taste. A new door isn’t just an aesthetic upgrade—it’s an energy-saving, security-boosting solution.
- Seal & Weatherstrip Services: Small changes can make a big difference. Our team ensures all window and door edges are tightly sealed and weatherstripped for maximum protection against wind, rain, and temperature swings.
