Portland ME Window Replacement provides professional sliding windows in Portland, ME for residential and commercial properties across Greater Portland and the Casco Bay towns. Horizontal sliders turn up in two places around Greater Portland: post-war ranches where they were original, and rental units where somebody needed a wide opening cheaply. They are an honest product with one specific weakness, and a Maine statute makes the second setting worth its own discussion.
The weakness first. A slider seals by brushing past the jamb rather than pressing into a gasket, so it will never match a casement for air leakage and will usually trail a well-made double-hung as well. The track also collects grit, and on a busy road it is that grit which eventually destroys the rollers rather than any failure of the sash.
Against that, a slider is the easiest window in the world to operate from a wheelchair, from behind a kitchen counter or with one hand already full. On a low, wide opening it delivers more ventilating area for the money than anything else on this site, and nothing has to swing into the room to do it.
Now the statute. The Home Construction Contracts Act defines a residence as a dwelling with three or fewer living units. Portland is full of two- and three-unit houses, so most of this city's small rental stock is covered: a written contract above $3,000, a deposit capped at one third, and the warranty language the statute prescribes.
Add a fourth unit and none of it applies. The same building, the same street, the same window order, and the statutory floor simply vanishes. Owners of four-unit and larger buildings routinely assume they are covered, and they find out that they are not at exactly the point where the coverage would have been worth having.
There is a further wrinkle worth knowing. Even where the act does apply, section 1489 lets both parties exempt themselves from it, provided the contractor specifically informs the owner of the rights being given up and both sides then agree to a contract without them. So a thin contract is not automatically a violation. It may be a waiver that you signed.
We do not ask anybody to waive the chapter and we do not hand out contracts that quietly fall short of it. On a four-unit or larger building, where nothing obliges us either way, we write the same terms in voluntarily and state inside the document that we are doing so and why.
On the windows themselves: specify tandem rollers on anything wider than four feet, ask to see a weep path you can actually put a finger into, and expect to clean the track twice a year. A slider that gets maintained outlives its reputation by a comfortable decade.
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 sliding windows
The difference between sliding windows that lasts and sliding 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.
