Windows and storm sash

Sash cords, glazing, loose joints, a sill gone soft: most of what goes wrong with an old window has a repair. We tell you when a window is past one.

An old double-hung window is a small piece of joinery: two sash, a frame, and cords and weights hidden in the pockets on either side. We repair them one window at a time. The sash come out, go to our shop on Danforth Street, and come back reglazed, repainted and running free. Where a sash is past saving, we make a new one to match.

  • What we don't do

    We don't install vinyl or aluminum replacement units, and we don't repair windows made in the last few decades; the maker is the better call.

What's included

  • New sash cords, and the weights checked and rehung

  • Glass reset in new glazing putty; broken panes replaced

  • Joints reglued and soft wood repaired or spliced

  • A sash that has been painted shut, freed

  • Weatherstripping, and a storm window if you want one

  • A matching new sash where the old one is past repair

White house wall with two double-hung windows and dark wood shutters

Pricing

What changes the cost

We print no figures. These are the things that move the number.

  • How many windows, and on how many floors

    A third-floor window on a ladder is a different day's work from one at ground level.

  • What shape the wood is in

    Sound wood is a repair. Soft wood is a splice. Rot through the frame is a different job.

  • The glass

    Original glass, with its waves, can be reset. Replacing it is a choice, not a requirement.

  • The paint

    Many layers on an old sash have to come off by the right method, and that takes longer.

  • Storm windows

    Interior or exterior, wood or aluminum. They're priced apart from the repair.

The work, in order

How the work goes

  1. Step 1: A note on every window

    On the house visit we write down each window's condition: wood, glass, cords, paint, frame. You keep the notes whether or not you hire us.

  2. Step 2: Your choice, in writing

    The estimate gives repair, replacement or a mix, window by window, and says what each leaves out.

  3. Step 3: Sash out, one window at a time

    A protective panel fills each opening while its sash is in the shop, so the house stays closed up.

  4. Step 4: Shop work

    Glass out, wood repaired, joints glued, sash reglazed and painted.

  5. Step 5: Back in, running

    New cords, weatherstripping, hardware. Every sash opens and closes by hand before we leave.

  6. Step 6: Walk-through

    We go window by window with you and hand over the notes with any touch-ups.

Permits and rules

  • Historic districts

    In a Portland historic district, or on a landmark, a change to an exterior window can need the city's review first. Repairing in kind often doesn't; replacing often does. We help you find out what applies at your address.

  • Houses built before 1978

    The EPA's rule for older houses covers window replacement every time, and repair when it disturbs more than a small area. It shapes how we set up the room, not whether we can do the work.

  • Storm windows

    A new storm window on a historic-district house can need review too. We check before we order one.

Questions about this work

Will my windows stop rattling?

A rattle is usually a loose stop, a worn cord or tired weatherstripping. Those are repairs, and the notes from the house visit say which one yours is.

Can you make old windows as tight as new ones?

Not quite. A repaired sash with weatherstripping and a good storm window closes the gaps that cause most drafts, but a new insulated unit still seals tighter. The comparison on our home page sets out where each one wins.

Do you ever replace a window?

Yes, when repair isn't the honest answer. We make a new wood sash or window to match the old profiles. We don't install vinyl.

My windows were painted before 1978. Does that change anything?

It changes how we work, not whether we can. We seal off the work area, keep dust down and clean up with a HEPA vacuum and wet wipes. The credentials page says what we hold.
