Six years running as a Best Pick Certified Pro is the credential Window Nation of Boston leads with — window, door, siding, and roofing installs out of Norwood, Massachusetts, part of a company that says it has operated nationally since 2002. Its BBB profile describes the Boston-market branch as locally started in 2020, covering Massachusetts, New Hampshire, and Rhode Island. Recent customers describe fast, professional crews: a July 2026 review called the process from estimate to installation quick, and an April 2026 review from a repeat customer praised the windows and front door and called the sales rep knowledgeable. Across platforms, Best Pick Reports gives the Boston market a 4.7-star average from 806 ratings and Thumbtack shows 4.6 stars from 75 reviews for the branch. It hasn't all gone smoothly: one review describes a window and screen order that ran more than two months behind schedule, with the delay communicated only the morning of installation, and another describes being offered a referral gift certificate while still deciding on an estimate. A reasonable call for a window, door, or siding replacement — ask about manufacturing lead times up front, and get any promotional incentives in writing before signing.
“This dispute between two window installation companies concerns alleged infringement of a trademark held by plaintiff L&P Boston Operating, Inc., d/b/a Window World of Boston (“plaintiff” or “L&P”). L&P claims that defendant Window Nation, LLC (“defendant” or “Window Nation”) has infringed and diluted its trademarked phrase, “House Full of Windows Installed”, through commercial use of similar terms. ... L&P is a Massachusetts corporation that sells and installs replacement vinyl windows, siding, doors and other home improvement products and services. It became the local franchisee of the natio”
Here’s what happens when you tell your Window Nation rep that you do not want to purchase on the spot and still would like to get other estimates. Sam was at my house and after going over everything he gave me his quote. I said he was the first company I had over to give me a quote and I wanted to get their estimates before making a decision. He asked what price would get me to commit today which I gave to him. He made a call to the office and they came back with a lower price but still not my price I told him. I thanked him for the time and said I would be in touch after I got some other quotes. He turned very sour, grabbed all his things and stormed out of the house and slammed my front door in my face as I was quickly following him out. It was so forceful that he damaged the door handle and dented the door itself. It’s all on camera. I’m sure their windows are nice but you can’t have representatives acting so childish when you don’t buy right on the spot. I called Window Nation to make a complaint. They are offering to replace the door handle and patch/paint the door. Still not a very enjoyable interaction with them.
Window Nation was professional, reliable, and top notch. From our first estimate appointment straight through to the follow up after the windows were installed, we had a great experience. We could not believe how fast the crew was installing our windows and they did a fantastic job. Would recommend to my family and friends
I cannot recommend this company highly enough. I am a second time customer and I have been extremely impressed with the quality of the the windows and front door that I purchased. The sales representative Joe Njajar was so knowledgeable about the products and very accommodating with his schedule. The installation team did a fantastic job as well. I definitely will be recommending this company to everyone who needs new doors and windows!
Nice reps. Decent price for some really nice windows.
I spent the weekend with my cousin who works for your company during the Thanksgiving week. I would absolutely love for your company to come to me so that I can have my 3400 square-foot home redone with windows and doors.
