6 Signs You Need New Windows (New England Homes)

1. You can feel the room before you touch the window

Stand a foot back from a closed window on a January morning. If there is a cold band of air pooling at your ankles, the seal or the sash has gone. A working double-pane unit should feel neutral from that distance even when it is well below freezing outside.

The candle test still works: hold a flame near the sash on a windy day. Movement means air is moving through, and air moving through is money leaving.

2. There is fog or haze between the panes

Condensation on the inside surface is a humidity problem. Condensation trapped *between* the panes is a failed seal — the inert gas has escaped and moisture has replaced it. That unit has lost most of its insulating value and cannot be repaired; the glass package has to be replaced.

If you see it in one window, check the rest of that elevation. Seals tend to fail in cohorts because they were installed on the same day and face the same sun.

3. The sash sticks, drops or will not stay up

On older Massachusetts homes this is often a sash-cord or balance failure, which is genuinely repairable and much cheaper than replacement. Do not let anyone sell you a whole-house replacement for a problem that is a broken balance in three windows.

But if the frame itself has racked out of square — the sash binds on one side and gaps on the other — the opening has moved, and no amount of adjustment fixes a frame that is no longer rectangular.

4. There is soft wood at the sill or the bottom rail

Press a screwdriver into the sill at the corners. If it sinks, water has been sitting there long enough to rot the wood, and the rot is almost always worse inside the wall than it looks from the room. This is the sign that moves a project from 'someday' to 'this year' — the longer it sits, the more of the framing around the opening comes into the job.

5. Your heating bill is climbing without a rate change

Windows are typically a modest share of a home's heat loss, so a single bad window will not show on a bill. A whole elevation of failed units will. If your usage has crept up over several winters while the house and the thermostat stayed the same, the envelope is the place to look — and windows are the visible part of it.

6. Street noise has become noticeable

Sound and air travel through the same gaps. A window that has become noticeably louder over the years has usually lost its seal, and the noise is simply the symptom you register before the draft.

Repair or replace — the honest split

The Massachusetts rule people miss

Window replacement is not on the Massachusetts exempt-work list, so plan on a building permit. And there is a requirement that catches homeowners out on like-for-like swaps: a bedroom window still has to satisfy the emergency escape and rescue opening requirements. Older openings were often sized before those rules, and dropping a modern unit into the same hole can make the clear opening smaller than the code allows.

That is a genuine safety issue, not paperwork. As your licensed contractor we size the units to code and file the permit in our name.

If you are replacing, do it by elevation

Windows on the same face of the house have had the same sun, the same wind and the same water. They tend to fail together. Replacing an entire elevation at once costs less per unit than returning three times, and it avoids the odd look of two generations of window on one wall.

Replace by elevation, not by symptom. The windows that failed first tell you which wall is next.
