Our Window Services in Portland, ME
Energy-Efficient Windows
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
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
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
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
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.
Double-Hung Windows
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.
Casement & Awning Windows
A casement seals better than anything else we install, because closing it pulls the sash into a compression gasket instead of sliding past a brush. In wind-driven Casco Bay rain that difference is measurable.
Sliding Windows
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.
Bay & Bow Windows
A bay is not a window. It is a small addition with glass on three sides, a roof, a floor, a header and a load path, and it is sold at a window's price with a window's paperwork.
Picture & Architectural Windows
Fixed glass is the cheapest performance on this site. No sash, no balance, no operator and no seal that has to open - just a lite set into a frame.
Egress Windows
Egress is the one job here where the size of your town does not help you. Everywhere else on this site the answer to "will anyone check this?" turns on whether more than 4,000 people live where you live.
Impact & Laminated Glass Windows
We sell laminated glass in Portland and we sell it honestly, which means selling it as laminated glass rather than as a hurricane system. The interlayer is genuinely worth buying up here, for reasons that have very little to do with the marketing attached to it further south.
Patio & Sliding Doors
A patio door is the largest single piece of glass most houses own, and the most common item on a contract that began with somebody knocking. Both of those facts are worth holding in mind before you shop, and the second one has a specific statutory answer in Maine.
French Doors
French doors are the product where the conversion people most want - slider out, hinged pair in - is also the one most likely to turn a door order into structural work. Whether that happens comes down to a header you cannot see from either side of the wall.
Entry Doors
An entry door is the job most likely to land just below the line where Maine's consumer protections switch on, and almost nobody buying one knows that the line exists. That is why this page opens with paperwork instead of with hardware and finishes.
Window Screens
Screens have quietly become a different product in Maine over the last decade, and the reason is heat pumps. Efficiency Maine has put an enormous number of them into houses in this state, and a house that cools with a heat pump is a house where the windows stop being opened in July.
Glass Repair & Insulated Glass Units
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.
Commercial Storefront & Glass
Commercial glazing runs under a different chapter of the code and under no consumer statute at all. Both of those facts change what a building owner ought to be asking for, and the second one catches small landlords out with real regularity.

Energy-Efficient Windows

Vinyl Replacement Windows
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. Maine issues no license to anybody who installs a window.

Fiberglass Windows
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. Pultruded fiberglass expands and contracts at close to the rate of the glass it holds.

Wood & Clad-Wood Windows

Aluminum Windows
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.

Double-Hung Windows
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.

Casement & Awning Windows
A casement seals better than anything else we install, because closing it pulls the sash into a compression gasket instead of sliding past a brush. In wind-driven Casco Bay rain that difference is measurable. The catch is that the seal depends on hardware, and hardware is the part no Maine code touches.

- crank operator
- casement hardware
- multipoint lock

Sliding Windows

They are an honest product with one specific weakness, and a Maine statute makes the second setting worth its own discussion. The weakness first.

Bay & Bow Windows
A bay is not a window. It is a small addition with glass on three sides, a roof, a floor, a header and a load path, and it is sold at a window's price with a window's paperwork. Everything difficult about a bay follows directly from that mismatch.

Picture & Architectural Windows
Fixed glass is the cheapest performance on this site. No sash, no balance, no operator and no seal that has to open - just a lite set into a frame. It is also the easiest way to accidentally ruin a room, and the mistake is nearly always the same one.

Egress Windows
Egress is the one job here where the size of your town does not help you. Everywhere else on this site the answer to "will anyone check this?" turns on whether more than 4,000 people live where you live. Here it does not matter, and you should proceed as though somebody were watching.

Impact & Laminated Glass Windows
We sell laminated glass in Portland and we sell it honestly, which means selling it as laminated glass rather than as a hurricane system. The interlayer is genuinely worth buying up here, for reasons that have very little to do with the marketing attached to it further south. Laminated glass is two lites bonded to a plastic interlayer, usually polyvinyl butyral.

Patio & Sliding Doors
A patio door is the largest single piece of glass most houses own, and the most common item on a contract that began with somebody knocking. Both of those facts are worth holding in mind before you shop, and the second one has a specific statutory answer in Maine. Title 32, chapter 128 licenses the door-to-door seller of home repair services, and section 14506 requires that seller's license number to appear on the contract in a prescribed form.

- gliding patio door

- patio door replacement
- door roller replacement
- tempered patio door glass

French Doors
French doors are the product where the conversion people most want - slider out, hinged pair in - is also the one most likely to turn a door order into structural work. Whether that happens comes down to a header you cannot see from either side of the wall. A slider and a hinged pair of the same nominal width do not want the same opening.

Entry Doors
An entry door is the job most likely to land just below the line where Maine's consumer protections switch on, and almost nobody buying one knows that the line exists. That is why this page opens with paperwork instead of with hardware and finishes. The Home Construction Contracts Act attaches to any home construction contract above $3,000 in materials or labor.

Window Screens
Screens have quietly become a different product in Maine over the last decade, and the reason is heat pumps. Efficiency Maine has put an enormous number of them into houses in this state, and a house that cools with a heat pump is a house where the windows stop being opened in July. That sounds harmless enough.

Glass Repair & Insulated Glass Units
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.
- foggy windows
- failed seal
- insulated glass unit
- IGU replacement
- glass only replacement
- double pane glass repair
- broken window glass
- argon leak
- desiccant spacer
- warm edge spacer

Commercial Storefront & Glass
Commercial glazing runs under a different chapter of the code and under no consumer statute at all. Both of those facts change what a building owner ought to be asking for, and the second one catches small landlords out with real regularity. The chapter first.

What Portland property owners ask us
Which window services does Portland ME Window Replacement handle?
Everything listed on this page, residential and commercial, across Portland and Greater Portland and the Casco Bay towns. Work is done by our own crews rather than handed to whoever is cheapest that week, which is the only way the workmanship warranty means anything.
Can I combine more than one service in a single job?
Yes, and it is usually cheaper. Bundling window work into one mobilization saves setup, disposal and travel, and it means one crew, one schedule and one written free estimate instead of three contractors blaming each other.
Do you give free estimates for every service?
Every one. We come out, measure, look at the real condition of the work area, and put an itemized free estimate in writing with materials and scope spelled out. No charge, no deposit, and no obligation to book.
What Portland Customers Say
They talked me out of half the order. Eleven openings quoted, four marked as repairs with the reason written next to them, and the parlor sash we thought were finished just needed cords and a little glazing. The four full-frame units went in over two days and the sill pan detail was explained before anybody started.
Ours was the only quote that mentioned a permit at all. The estimate had the town population on it and a line explaining why the code office would want to see the enlarged opening. Everything else we had been sent was a price and a brand name. That alone decided it for us.
Two fogged units in the dining room. I expected to be sold the whole elevation and instead got glass only, in the sash we already had, at about a fifth of what the last company quoted. They wrote the coating and spacer type on the order and left the labels on until I looked at them.
Basement bedroom for our daughter and I had no idea about the sill height rule. They measured the clear opening, told me the slider I had picked would fail on height, and put a casement in the cut opening instead. The inspector they arranged went through it with me at the end.
