Window replacement in Northampton: what to know
The cement industry built Northampton Borough, and it built it solid: block after block of double-brick twins and frame singles between Main Street and the Lehigh, most of them dating from 1900 to 1930, with the Hokendauqua Creek cutting through and Laubach Avenue climbing toward the newer sections. Beyond the borough, Allen and East Allen Townships add farmhouses and a growing number of 1990s and 2000s developments off Route 329 and Route 987, so the phrase replacement windows Northampton PA covers everything from a hundred-year-old twin to a twenty-year-old colonial.
In the borough, the story is wood. Original double-hungs with cast-iron weights, sashes painted shut somewhere in the 1970s, glazing that has fallen out, and aluminum storms that were an improvement in 1965 and are a liability now. Some homes had vinyl inserts put in during the 1990s that were never sealed properly, so they leak air around the frame even though the glass is fine. In the townships, it is the familiar builder vinyl: fogged panes, dead balances, frames that warped on the sunny side.
The river keeps summer humidity high and the open farmland to the north gives winter wind an unobstructed run into the borough from the northwest. Condensation on old glass, drafts at the meeting rail, and rooms that feel colder than the thermostat says are the usual complaints. A window company near Northampton that has worked these brick twins knows how to measure a settled opening and how to trim a new unit so the brick mould still looks right.
What Northampton homes usually need
Double-brick twins with settled openings
The borough’s brick twins have shifted over a century, so openings are rarely square. Each one is measured individually and the new unit is fitted and sealed to the actual shape, not the nominal size.
Badly installed 1990s inserts
Some borough homes have vinyl inserts that were set without proper foam or flashing. Air leaks around the frame even though the glass is intact. Removing and reinstalling correctly, or replacing outright, solves it.
Aluminum storm windows past their life
Bent, rattling storms on the borough streets no longer seal. New insulated windows make the storms unnecessary and clean up the exterior of the house in one step.
Builder vinyl in Allen and East Allen Townships
The developments off Route 329 and 987 have reached the age where seals fail and balances quit. Full replacement with a better frame and warm-edge glass is the standard fix for those homes.
Lead-safe work in pre-1978 homes
Most of the borough qualifies. Installers follow EPA lead-safe practices when disturbing painted trim; ask how the crew contains dust and cleans, especially if children or grandchildren visit.

How the visit works in Northampton
After the form is submitted, one vetted installer who covers Northampton reaches out to arrange the free in-home measure. A borough twin takes about an hour; a large township colonial takes longer. Have someone there who knows which windows leak, stick, or sweat.
On the brick twins, the installer measures each opening in three places and checks the depth of the brick return so the new unit sits correctly. Sills are probed for rot, storms are noted for removal, and the exterior finish is recorded so the trim is covered honestly. Township homes are checked for whether the existing frame is sound enough for inserts. The quote is written and itemized.
Most municipalities treat like-for-like replacement as routine work; your installer confirms with the Northampton borough office — or Allen or East Allen Township for addresses outside the borough — before anything is ordered. If the house sits in a locally designated historic district, visible exterior changes may need review. Township developments with associations often have exterior guidelines, so bring your covenants to the visit.
Borough parking is on-street and the lots are narrow, so crews stage from the alley behind most blocks. Township driveways make it simpler. Windows go in one at a time to keep the house sealed, and installation for an average Northampton home is typically a day or two once the product arrives. The schedule comes in writing with the quote.
Which window styles fit Northampton homes
Double-Hung Windows
The borough’s brick twins were built around double-hungs, and modern versions keep the proportion while adding insulated glass. Tilt-in sashes make the second floor cleanable from inside on a narrow lot.
Casement Windows
Homes facing the open farmland to the north take the winter wind directly. A casement locks against its seal and shuts out the draft that a sliding sash lets through, and it suits kitchen windows over a sink.
Awning Windows
Useful for basement openings in the borough where a hopper or awning lets you ventilate during summer rain without water coming in. Awnings also work well under a fixed unit in a township family room.
Composite Windows
For a brick twin where the exterior trim should look like painted wood but never need painting, a composite frame is the answer. It holds tight through freeze-thaw and takes a color that suits the brick.
Before the visit: a Northampton checklist
- Note which windows are painted shut, which leak around the frame, and which sweat.
- Look at the storm windows and decide whether you want them gone.
- Confirm whether you are in the borough or in Allen or East Allen Township.
- Find your association covenants if your development has them.
- Check the basement windows behind the wells for rot.
- Clear a path to each window and plan for alley or street staging.

Frequently asked questions
Do I need a permit for replacement windows in Northampton, PA?
Most municipalities treat like-for-like replacement as routine work; your installer confirms with the Northampton borough office — or the township office if you are outside the borough — before anything is ordered. If anything is required for your address, the installer handles it, and that gets confirmed at the visit.
Can the windows in my 1910 brick twin be replaced without changing the exterior look?
Yes. Insert replacements fit inside the existing frame so the brick mould and interior casings stay, and the exterior is capped or trimmed to match. If the house sits in a locally designated historic district, visible exterior changes may need review, and your installer raises that at the visit.
My 1990s inserts are leaking air around the frame. Is that fixable?
It is. Usually the units were installed without foam or proper exterior sealing. The installer looks at the frame at the measure and tells you whether it makes sense to reseal what is there or replace the unit with a properly installed one. Both options go on the written quote if both are viable.
Will new windows fix the condensation in my Northampton home?
If the moisture is on the room side of the glass, insulated glass and frames usually end it because the interior surface stays warmer. If it is between the panes, the seal has failed and replacement solves it. If the basement is damp and pushing humidity up through the house, the installer will tell you that windows alone will not finish the job.
Is the whole township covered or only the borough?
Both. The matched installer works Northampton Borough, Allen Township, East Allen Township, and the surrounding area. Your ZIP goes on the free form and we confirm it before making the introduction.
How long does a Northampton brick twin take to finish?
Installation is typically a day or two once the windows arrive, one opening at a time so the house stays closed up. Made-to-order sizes for settled brick openings add lead time before that. Your installer puts both dates in the written quote.
