What we write about, and why
Every post here answers a question Manchester property owners actually ask before they hire anyone — what work costs, which materials are worth the upcharge, how long a job really takes, and the shortcuts that look fine for two years and then do not.
The writing comes from the same people doing the work in Manchester, NH and the New Hampshire Merrimack Valley, which is why the numbers are specific and the advice sometimes tells you not to spend money.
Need help now rather than reading
Skip the articles and go to the page for what you need — each one covers pricing, scope and how to start:
- Energy-Efficient Windows in Manchester — Manchester sits in Climate Zone 5A, where the adopted energy code asks a replacement window for a U-factor of 0.30 and asks nothing whatsoever about solar gain. That is the entire number.
- Vinyl Replacement Windows in Manchester — Vinyl is the right answer in more Manchester openings than its reputation suggests, and the reason has little to do with price. An insert unit slides inside the frame you already own, which means the painted casing, stool and apron mostly stay where they are.
- Fiberglass Windows in Manchester — Fiberglass earns its premium in full-frame work, which is exactly the situation this site spends most of its time talking people out of. That is not a contradiction, but it does mean the recommendation here is narrower than a manufacturer would like.
- Wood & Clad-Wood Windows in Manchester — This is the highest-disturbance product on the site and the page where you should read the scope most carefully. A clad-wood unit is beautiful, it belongs on a great many Manchester houses, and installing one takes apart more painted material than anything else we do.
- Aluminum Windows in Manchester — We do not recommend aluminum windows for houses in Manchester and this page exists to explain the refusal rather than to sell around it. The material has a real place here, and it is on commercial buildings rather than on the street where you live.
