When to replace your windows instead of repairing them

Homeowners usually call us after a cold snap, when they can feel air moving across a room. The instinct is to replace everything. Sometimes that is right. Often it is not, and a few hundred dollars of repair buys another decade.

Repair is usually enough when

• The frame and sash are solid wood with no soft spots.
• The draught traces back to failed weatherstripping or a worn sash lock.
• The glass is intact and the seal between panes has not failed.
• Only the exterior glazing putty or paint has broken down.

In those cases we can rebuild the sash, replace the balances and weatherstripping, and get the window operating properly again. On an older home with original detailing, that is often the better outcome anyway.

Replacement is the honest answer when

• You can see fog or condensation between the panes. The insulating seal has failed and it cannot be repaired.
• The frame or sill is soft when you press a screwdriver into it. Rot spreads and it will keep spreading.
• The window will not stay open, or will not close square, because the frame has racked.
• The unit is single-glazed and you are heating the street through it every winter.
• You are already opening the wall for siding work. Doing both at once saves a full mobilisation.

Fogged glass between the panes is the clearest signal. Once that seal is gone, the window has lost most of its insulating value and no amount of caulk brings it back.

The part most quotes leave out

When we pull an old window, we are looking at the rough opening for the first time in decades. Soft sills, failed flashing, and sagging headers are common and none of them are visible during an estimate. A quote that has no line for repairing what is behind the unit is a quote that will grow once work starts.

We tell you what we find, show you photos, and price the repair before we do it. It is the difference between a number you can plan around and a number that moves.

One more thing about timing

Windows can be replaced through a New England winter. We work opening by opening so the house is never left open to the weather, and interior temperatures stay manageable. Waiting for spring usually means waiting in a queue, not getting a better job.
