Alec's Construction replaces windows, entry doors and patio doors in Coram, Suffolk County, working out of the yard in East Patchogue. We treat an opening as carpentry, because that is what it is — the unit is a component, and the sill, the flashing, the shim pack and the trim are the job.
The Window Stock in Coram
Original builder windows now forty-odd years old, generally simple sizes in quantity. In the townhouse and condominium communities the exterior openings are usually common elements, so the association has a say in what may be installed.
Builder Aluminum and First-Generation Vinyl
The original windows in this stock are mostly aluminum with no thermal break, or early vinyl from the 1980s and 1990s. Both have a recognisable failure.
Aluminum with no thermal break conducts heat straight through the frame. On a January morning the frame frosts and runs with condensation while the glass above it stays clear. That is not a repair — the metal is the bridge.
First-generation vinyl fails at the welded corners, and once a corner opens the sash racks and stops meeting at the lock. You can usually see it as a hairline split at the corner of the frame or a lock that needs the sash pushed to engage.
On a split or a hi-ranch, the lower-level windows and the sliding patio door are normally the coldest and leakiest openings in the house, and they are where the first money should go. The bedroom windows upstairs are frequently in better shape than the ones people never think about.
Insert or Full-Frame
This is the decision that most affects whether the work lasts, and most quotes skip it.
An insert replacement leaves the existing frame in the wall and fits a new complete window inside it. It is fast, the exterior is never disturbed, and it is the right call where the frames are sound, dry and square. You lose an inch or so of glass at every opening, and whatever is behind the old frame stays there.
A full-frame replacement takes everything out to the rough opening. The sill and the flashing get inspected and corrected, rot gets repaired rather than concealed, the original glass area is kept, and the new unit is flashed into the water-resistive barrier in the right order. It costs more and it disturbs the trim.
On most houses the honest answer is a mix — full-frame on the weather elevation and anywhere there is staining or rot, insert on the sound, sheltered openings. If siding is also on the list, full-frame during the re-side is much cheaper than full-frame on its own and it is the only way to get the flashing genuinely right.

The Two Things We Check Before Ordering
Egress. Every sleeping room and every finished basement needs an emergency escape opening, and the code sets a minimum net clear opening — 5.7 square feet in most cases — with minimum clear height and width and a maximum sill height. Net clear means the hole you could climb through with the sash fully open. Because an insert unit is smaller than what it replaces, this is exactly how a compliant bedroom window quietly becomes a non-compliant one.
Permits. Coram files with the Town of Brookhaven. Whether a like-for-like replacement inside an existing rough opening needs a permit varies, and it is a different answer again if an opening is being enlarged, a window is becoming a door, or the address sits in a flood or windborne-debris area. We call with the actual address and the actual scope before we quote a schedule.
What a Written Scope From Us Says
- Which openings are insert and which are full-frame, and why
- The NFRC numbers on the units being installed — U-factor and SHGC, against the Climate Zone 4A prescriptive figures of 0.32 and 0.40
- That the gap between the unit and the framing is sealed deliberately with low-expansion foam or backer rod and sealant, on every opening
- The flashing detail, and a sill pan on every door
- Which bedroom and basement openings were checked for egress
- Interior and exterior trim, and who is finishing it
Booking Coram
Window and door work runs through the winter on Long Island because openings are done one at a time and closed the same day. The sensible sequence, if the attic is also on the list, is the attic first — it is cheaper, it usually buys more comfort per dollar, and it does not make the window job any harder.

Frequently Asked Questions
I own a Coram townhouse. Can I change my own windows?
Frequently not on your own. In townhouse and condominium communities the exterior openings are usually common elements, which means the association decides what may be installed and often specifies a style, a colour and sometimes a supplier. Get that in writing before anything is measured. Where the unit is a detached house in a development with a covenant, the same question applies in a lighter form.
Will new windows lower my heating bill?
They help, and they are rarely the biggest lever on a Long Island house. Air sealing and attic insulation usually deliver more comfort per dollar, and the rim joist or a knee wall is often the larger loss. Windows are worth doing for the reasons they are actually failing — rot, failed seals, frames that no longer close. We will tell you honestly where they sit in the order.
Do I have to do the whole house at once?
No, and on most houses you should not. Openings fail at different rates depending on which way they face and how much weather they take, so the west and south elevations are usually years ahead of the north. We measure everything, rank it by condition and exposure, and give you a list in the order it is worth spending on.
How long does a window job take?
An insert replacement runs several openings a day and each one is closed the same day it is opened. Full-frame is slower per opening because the trim comes off inside and out and goes back, and there is carpentry if there is rot. A typical whole-house job is measured in days rather than weeks, and the house is never left open overnight.
