Portland ME Window Replacement provides professional double-hung windows in Portland, ME for residential and commercial properties across Greater Portland and the Casco Bay towns. Almost every original window in Portland's older neighborhoods is a double-hung, and almost every whole-house quote you receive will price them as a single number. Price them per opening instead. That one change tells you more about a bidder than anything else you can do in an hour.
Here is why it matters in this state particularly. The Home Construction Contracts Act caps the down payment on a residential job at one third of the contract price. On a single opening that is a modest figure. On a twenty-two window package it is a large prepayment handed to a firm with no license file standing behind it anywhere.
Per-opening pricing also exposes the openings that should not be replaced at all. A tall parlor double-hung with sound old-growth stiles and a broken cord is a two-hour repair with a length of rope and a little glazing putty. Buried inside a whole-house average it disappears completely, and you pay replacement money for a rope.
The mechanics are worth understanding. Original units run on weights in a pocket beside the jamb. Modern ones run on spiral or block-and-tackle balances built into the frame itself. Converting from one to the other means the weight pockets get filled or simply abandoned, and a pocket insert narrows the visible glass by an inch or two on each side of the opening.
That narrowing is where double-hungs collide with egress. Bedroom openings have a minimum clear area to meet and a maximum sill height above the finished floor, and an insert reduces the clear opening in both directions at once. We measure the clear dimensions before ordering rather than afterwards, and we will tell you in writing if a sleeping room fails.
Fire and life-safety requirements are the one part of this that does not depend on the size of your town. Section 9725 keeps the fire and building-related codes and standards in force in their entirety alongside the Maine Uniform Building and Energy Code. Enforcement of the energy chapter may be optional below 4,000 residents. Life safety was not written that way.
For a house on the peninsula the practical answer is nearly always a mix. Repair the sash worth repairing, insert where the jamb is sound and square, and go full-frame only where the frame itself has gone. Any bidder who returns one product for every opening in a hundred-year-old house has not actually looked at the openings.
We walk the house with you, mark each opening as repair, insert or full-frame on the estimate with the reason beside it, and let you accept the lines separately. You are allowed to do half the house this year and the rest when it suits you.
Our licensed and insured team brings the right materials and equipment to every job — a like-for-like sash swap that never disturbs the rough opening, full-frame replacement taken back to the framing at the jamb, an insulated glass unit reglazed into the sash already on the building, warm-edge spacer stock named by type on the purchase order, a certified whole-unit label left on the pane until sign-off, low-expansion foam packed into the shim gap in place of rope insulation — and backs the work with a written workmanship warranty. We serve Portland and nearby communities including South Portland, Biddeford, Scarborough, Brunswick.

Materials, equipment and how we do double-hung windows
The difference between double-hung windows that lasts and double-hung windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with a like-for-like sash swap that never disturbs the rough opening, full-frame replacement taken back to the framing at the jamb, an insulated glass unit reglazed into the sash already on the building, warm-edge spacer stock named by type on the purchase order, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Portland job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Greater Portland and the Casco Bay towns means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Portland Chooses Portland ME Window Replacement
- ✓We put your municipality's 2020 census count on the estimate and state whether Title 10, section 9724 obliges it to enforce the code or leaves the choice to the town. No other quote you get will tell you that, and it changes who is checking the work.
- ✓Openings are priced one at a time and marked repair, insert or full-frame. A sound sash with a failed cord is a two-hour repair, and inside a whole-house number that repair silently becomes a replacement you paid full price for.
- ✓We will tell you to spend the money on air sealing and insulation instead when that is the honest answer, because Efficiency Maine pays toward those and nothing toward glass. We would rather lose a job than sell you a payback that does not exist.
- ✓In towns under 4,000 residents, where nobody is required to inspect, we price an independent third-party inspector certified under Chapter 3 as an optional line. You can strike it. Most people looking at a bay or a cut foundation opening do not.
