Portland ME Window Replacement provides professional glass repair & insulated glass units in Portland, ME for residential and commercial properties across Greater Portland and the Casco Bay towns. A fogged window is the most over-sold problem in this trade. The seal between two lites has failed, moisture has reached the cavity, and the fix in most cases is a new sealed unit set into the sash you already own, at a fraction of the price of the window somebody quoted you.
Here is the structural oddity that makes this page matter in Maine specifically. Glass-only work is a repair rather than an alteration, so Chapter 5 of the Maine Uniform Building and Energy Code barely engages with it and there is no permit conversation to have. It also almost never reaches $3,000, so the written-contract requirement does not attach either.
Put those two together and insulated glass replacement is the least documented work in the entire state. No license, because Maine issues none for this trade at all. No inspection, because nothing has triggered one. No statutory contract, because the number is too small to reach the threshold. Whatever record ends up existing is the record you insisted on.
So insist on one. Get the unit dimensions, the overall thickness, the glass make-up, the coating and the spacer type written down before anybody places an order. A warm-edge spacer and a low-emissivity coating are not the default on a replacement lite unless somebody specifies them by name, and the performance difference between the options is not subtle.
On whether to repair at all: if the sash and frame are sound and the unit still operates, replace the glass. If the sash has rot at the bottom rail, if the balances are gone and no longer obtainable, or if the frame itself has failed, then the glass is not really your problem and a new unit is the honest answer. We will look and tell you which of those we are dealing with.
Argon does leak out over many years and nobody can measure that in your house with any instrument they carry. Ignore any diagnosis built on argon loss. The observable failure is moisture in the cavity, and moisture is either there or it is not.
Where the glass sits near a door edge, close to a walking surface or beside a tub, the replacement lite has to be safety glazing, tempered or laminated. That is one of the very few points at which a glass repair does carry a code requirement, and it is one people get wrong because the original pane often went in before anybody was asking.
Broken glass is a same-week job for us and a board-up is a same-day one. Single-pane sash in an older house can still be reglazed traditionally with points and putty, which on an original window is a better and longer-lived repair than any modern substitute.
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 glass repair & insulated glass units
The difference between glass repair & insulated glass units that lasts and glass repair & insulated glass units 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.
