Portland ME Window Replacement provides professional aluminum windows in Portland, ME for residential and commercial properties across Greater Portland and the Casco Bay towns. 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. We are going to tell you which building it belongs on, because on that building it is frequently correct and vinyl is not.
Bare aluminum conducts heat roughly a thousand times better than the vinyl beside it. In an unbroken residential frame that produces a cold bridge, running condensation on a January morning, and in the older stock a sill that stays wet for long enough to rot the wood underneath it. There is no glass package that fixes a frame doing that.
Thermally broken aluminum is a different product. A polyamide strut separates the inside and outside faces so the metal no longer runs straight through the wall. That is what makes commercial aluminum viable this far north, and it is why you see it going into new mixed-use construction all over the peninsula and along Forest Avenue.
Where it earns its keep is span and abuse. An aluminum frame carries a large lite with a sightline no vinyl or wood section can approach, and it survives a ground-floor entrance being used four hundred times a day without complaint. On a Congress Street storefront or a converted mill floor in Westbrook that is exactly the requirement, and nothing else meets it.
Commercial work in Maine runs under Chapter 4 of the Maine Uniform Building and Energy Code, which modifies the 2021 International Building Code, rather than the residential chapter. Different chapter, different assumptions about occupancy and means of egress, different expectations of whoever is doing the work and of the paperwork they leave behind.
It also sits outside the consumer statutes entirely. The Home Construction Contracts Act defines a residence as a dwelling with three or fewer living units and states plainly that buildings used for commercial or business purposes are not subject to the chapter. On a commercial aluminum job there is no statutory contract floor, no cap on the deposit and no prescribed warranty language.
That is worth saying out loud, because it inverts the advice everybody expects. Homeowners receive protections they never asked for and often do not know about. Commercial owners receive none whatsoever and have to write their own. If you are a small landlord ordering storefront aluminum, the contract you negotiate is the only protection anywhere in the transaction.
So: no residential aluminum from us, at any price. Thermally broken aluminum on a commercial or mixed-use opening, quoted with the finish system named, the thermal break identified by type, and terms you have genuinely read rather than terms a statute happened to write on your behalf.
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 aluminum windows
The difference between aluminum windows that lasts and aluminum 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.
