What We Install & Repair
Your windows and doors do more than frame a view — they carry your home's insulation, security, and curb appeal. Old, worn-out windows and doors let heat escape, drive up utility bills, and make a house look tired. Senco Home Services provides replacement window services and door installation for homeowners across Tewksbury, MA and the surrounding towns, with custom-fit window replacement and entry door installation built to last.
Energy-Efficient Replacement Windows
We install Energy Star-certified replacement windows and Energy Star new construction windows, which cut drafts and lower heating and cooling costs compared to older, worn-out glass. Styles include classic double-hung, casement, awning, hopper, bay and bow, and garden windows, available in vinyl, fiberglass, wood, and composite materials depending on the manufacturer. Every window is custom-fit to your home's existing openings, so there are no drafts or gaps around the frame.
Entry, Storm & Patio Doors
Beyond windows, we install wood, fiberglass, and steel entry doors, plus storm and sliding patio doors — most through the same Harvey, Andersen, and Pella lines we use for window replacement, so your doors and windows can match. A new entry door is one of the fastest ways to improve both security and curb appeal in a single afternoon.

We had an excellent experience with Senco. Chris was amazing! He was professional, patient, explained things clearly and answered all our questions. He always returned our phone inquiries. He and his workers went above and beyond our expectations. His crew replaced our roof in one day. Clean up was great. We also had Senco remove the ice dams prior to having the roof replaced. Once again, Senco's pricing was fair, the crew was hard working and responsive to any concerns we may have had. I highly recommend this company and would use them again.Elaine Levine · Google Review
Senco did many homes in my neighborhood. I recognized their competence, honesty and quality right away and knew I had to have the Senco team on my roof too. Very satisfied with all aspects of the demolition and installation which was quite complex. Replaced facia boards with AZEK, new gutters, and a new roof. Thanks again Senco!! Excellent job!!Jim O. · Google Review
Owner, Chris, was extremely knowledgeable and very professional. He always responded promptly to our questions and we always felt we were important to him. His crew worked so great together, like they never had to ask each other for anything, they just knew what was next. The job was started earlier than planned and everything was done above and beyond what one would expect. We would, and have, already recommended Senco Home Services to other homeowners and look forward to having him back to replace our old windows. Thank you, Chris, for making this an easy decision for us and for providing quality workmanship. Stephen and Melissa Spinosa in BurlingtonJenna Spinosa · Google Review

Windows & doors questions
How much do replacement windows cost in Massachusetts?
It depends on the number of windows, the size and style you choose, and which manufacturer you go with — Harvey, Andersen, and Pella all price differently. We don't quote a number without seeing your home, so we offer a free, no-obligation estimate for an honest price on your specific windows or doors. Financing is available either way — see your financing options.
What's the difference between Harvey, Andersen, and Pella windows?
All three are trusted manufacturers we install every day, but they're built differently. Harvey windows are known for durability and low maintenance with some of the best energy efficiency in the industry. Andersen builds from its own Fibrex composite — twice as strong as vinyl — in a wide range of colors and styles. Pella offers the most material choice, with vinyl, fiberglass, and wood frame options plus matching entry and patio doors. We'll help you pick the right fit for your home and budget.
Do you install entry doors and storm doors, or just windows?
Both. Beyond replacement windows, we install wood, fiberglass, and steel entry doors, plus storm and patio doors — most of it through the same Harvey, Andersen, and Pella lines we use for windows, so your doors and windows can match.
Are your replacement windows Energy Star certified?
Yes. We install Energy Star-certified replacement windows and Energy Star new construction windows, which cut drafts and can lower your heating and cooling costs compared to older, single-pane or worn-out windows.
Do you offer financing for window and door replacement?
Yes. Through our lending partner GreenSky, you can finance windows and doors with 0% financing for 12 months (no interest, no payments), plus longer 10- and 15-year plans with rates from around 4.99% if you'd rather spread out a bigger project. The credit check is a soft pull and won't affect your score. See your financing options.
How long does a window or door installation take?
Most single window or door replacements are custom-fit to your existing opening and completed in a day. Larger projects with multiple windows or doors take longer — we'll give you a clear timeline during your free estimate.
