What we write about, and why
Every post here answers a question Portland 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 Portland, ME and Greater Portland and the Casco Bay towns, which is why the numbers are specific and the advice sometimes tells you not to spend money.

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 Portland — This is the page where we argue you should spend the money somewhere else. If you are looking at windows because your heating bill hurts, Maine's own efficiency program has already told you where the return is, and it is not here.
- Vinyl Replacement Windows in Portland — Vinyl is the most common replacement window in Greater Portland and, by a wide margin, the one most likely to arrive at your house uninvited. Those two facts are connected, and the connection is the reason this page starts where it does.
- Fiberglass Windows in Portland — Fiberglass is sold on a thirty-year argument. That is a fair argument to make about the material and a much harder one to make about the transaction, because in Maine there is no license file anybody can look up in thirty years to find out who did the work.
- Wood & Clad-Wood Windows in Portland — Clad wood is what people buy when the house deserves it, and it is also the product most likely to turn a window order into an alteration. Understanding why that distinction matters in Maine is the difference between a smooth job and an expensive surprise.
- Aluminum Windows in Portland — Aluminum has a place in Portland and it is not on a house. We are not going to spend a page refusing to sell it.
