Window Replacement With Every Opening Flashed

Standard and custom units, installed square, flashed so water goes back out, and finished with exterior trim wrapped in white aluminum.

Window Replacement installed by 4Ever Exteriors

Old windows in Massachusetts houses tend to fail in the same handful of ways. Sashes rattle in their tracks. Glazing putty cracks and falls out. Sills rot because water has been sitting on them since the 1950s. And on homes that got vinyl siding over the original clapboard, the trim around each window was often just covered up, not fixed.

When we replace your windows, the old unit comes out and we look at the rough opening before anything new goes in. Rotted sills and wet sheathing get photographed so you see them too. Then we flash the opening, tape and seal the weather barrier laps, and set the new window square, level and shimmed per the manufacturer manual.

Outside, your new window gets exterior trim and white aluminum wrap. That means no more scraping and painting wood casings every few summers. Inside, you get a unit that opens, closes and locks the way it should. We install standard sizes and custom units for older openings that don't match anything on the shelf.

What's included

  • Removal of your old window units
  • Inspection and photos of each rough opening
  • Repair of rotted sills or sheathing when found
  • Flashing at every window opening
  • Weather barrier laps taped and sealed
  • New units set square, level and shimmed
  • Exterior trim wrapped in white aluminum
  • Old units hauled away and site magnet swept daily

Signs it's time

  • You feel a draft near the window on a windy day
  • Sashes stick, rattle or won't stay open
  • Fog or moisture shows up between the panes
  • Paint is peeling off the sill or the wood feels soft
  • You see water stains on the wall below a window

Custom units for older Massachusetts openings

Plenty of homes here were built long before window sizes were standardized. Capes, colonials and mill-town housing from the 1920s through the 1950s often have openings that are a little different from one window to the next. Forcing a stock unit into those openings means big gaps stuffed with filler.

So we measure every opening during your free estimate. Where a standard unit fits, we use it. Where it doesn't, we spec a custom unit sized to the opening. Your written proposal lists which windows are which, so you know exactly what you're paying for and why.

On the North Adams re-side, every window and door got wrapped in aluminum as part of the job. If you're planning new siding too, doing both at once means your openings get flashed into the new weather barrier from the start.

What happens behind your window replacement

You won't see most of this once the job is done. That's why we photograph it before we cover it.

  • Substrate inspected and photographed before it's covered
  • Every opening flashed so water gets directed back out
  • Seams and laps of the weather barrier taped and sealed
  • Fastening and clearances per the manufacturer's manual
  • Soffit ventilation kept open, corners and returns sealed
  • Site cleared and magnet swept at the end of every day

About window replacement

Do I need to replace every window at once?

No. Some homeowners replace the worst few first and do the rest later. Others do the whole house at once, which keeps the trim and wrap consistent all the way around. We'll walk your house during the free estimate and tell you which windows need attention now and which can wait.

What happens if you find rot around a window?

We stop and show you. Rotted sills and wet sheathing get photographed before anything gets covered. We explain what it takes to fix it and add it to your scope in writing. Nothing gets buried behind new trim without you knowing about it.

Why do you wrap the trim in aluminum?

Painted wood trim around windows peels, cracks and rots, especially on the sides of your house that take wind-driven rain. White aluminum wrap covers that wood so you don't have to scrape and paint it every few years. It's the same wrap we use on fascia.

Should I do windows and siding together?

If you're planning both, doing them together saves trouble. With your siding off, we can flash each new window directly into the new weather barrier and tape every lap. Do the windows later, and part of the new siding has to come back off around each opening.
