Hung and Sliding Windows Before November Rain: Latches, Fog, and Cracks in Metro Vancouver

Monday, November 2. The clocks fell back yesterday, so evening is already dark. Across Vancouver, Burnaby, Surrey, Coquitlam, and the Fraser Valley, early November often brings a longer rain and a wind that drives water sideways. On a lot of houses the sash lifts, or it slides left and right. That is a double-hung, a single-hung, or a horizontal slider.

A sash you crank shut is the casement and awning note. A pane that does not open is the picture window post. Glass you walk through is the sliding patio door page. This one stays on a sash that lifts, or slides sideways.

A dry hour this afternoon is easier than a look after dark. Remembrance Day is Wednesday, November 11. More people are often home that mid-week day.

A dry look at the sash that moves

Do this from inside. Skip a ladder while the wind is up. A screen is not the weather seal.

• Close it and lock it. On a double-hung, the lock should pull the two sashes together. On a slider, the latch is usually at the side jamb. If the handle stops short, the sash is not in.
• Look along the meeting rail. Daylight where the sashes touch is a path for wind-driven rain. On a slider, that gap is often at the side.
• Check a tilt-in sash. If a corner is not clicked home, it can look closed and still leak. Do not force the latch.
• Press the glass gently near a corner. If the pane shifts, say so. Do not pry the stops off.

If daylight shows at the lock and the glass is clear, do not order glass first.

Rain at the rail, the track, or the sill

A sash that almost meets can pass a light shower. It often fails when rain is blown at the glass for hours.

• Water at the meeting rail often means the lock is not drawing the sashes together, or the weatherstrip is flat. Do not caulk the rail shut if you still need the window to open.
• A slider that looks closed from across the room may be off the track. A gentle lift, from inside, sometimes seats it. If it jumps off again, stop.
• Standing water in the sill is often a drain, not the glass. Our weep holes post is that check. Do not seal those openings.
• A draft with the lock finished may be the weatherstrip or the frame. A clear pane can still sit in a drafty sash.

Water on the stool, with the glass still whole, is often the sill or the cladding. That check is our water on the sill post.

Fog you cannot wipe off

Moisture on the room side of a cold sash, on a November morning, often wipes away. That is usually the room. Our room-side condensation post and our first frost note sort that wipe test. Dew on the outside is the exterior condensation page.

Fog or a milky stain between the panes does not wipe off. The seal has usually failed. Cleaner will not dry the cavity.

• One sash can fog while the other stays clear. You often replace that unit, not both, when the frame is sound.
• A slider can fog in the moving panel only. Say which lite is hazy.
• The frame can still be sound. Our glass-only guide is that split.

Waiting through the wet season can etch the glass inside a failed seal. Our etching post is that limit. Fog alone can wait for a booking. A low-E coating, if you are already replacing the unit, is our low-E note.

A crack, a chip, or a sash that will not stay put

A surface mark is not an open pane. Our scratched or chipped guide covers a mark that has not become a hole. A crack with no impact, often after a cold night, can be thermal stress. Our cold-morning crack post is that pattern. The cause can vary.

• An edge chip can travel when the sash is slammed. Photograph it. Do not drill it or fill it.
• A crack with no hole is damaged glass. Tape only marks it.
• Glass that rattles is loose in the stops. Leave it, and say that it moves.
• A hole, or cubes in the track, means the opening is open. Do not keep sliding a broken sash.

Tempered glass cannot be patched. See our tempered cracks note. We confirm the glass type before the unit is made. Laminated or tempered is the choice when the next lite should stay together if it breaks again.

If the glass breaks while the wind is up

People first, then water, then the opening.

• Keep hands off hanging glass. Shoes on. Children and pets out of the room.
• Leave glass that is still held. Pulling shards out can drop the piece slowing the wind.
• Do not force a sash jammed with glass. If it is partway open, leave it and cover what you can.
• Cover it from inside. Plastic and tape slow a short rain. Skip a ladder outside while the wind is up.
• Call emergency glass when the room is open to the weather. The shop at 1289 Hornby St is open 24 hours. Same-day glass is offered when possible, depending on size, type, and access. Nothing here promises a time.

Photograph the sash and the floor before you sweep. We can help with insurance documentation. Your insurer decides the claim. This is not advice about your policy. See our storm documentation post and our board-up note.

New glass in the sash, or a wider job

Window replacement is often a new sealed unit in the existing sash, when the sash is firm and still able to meet the frame.

• Glass-only fits when the lock can finish and the stops can come off and go back.
• A full window is the usual talk when the frame is soft, the balances will not hold the sash, or the slider jumps the track. New glass in a sash that will not latch can still leak.
• Say what is around the glass. Wood stops, a vinyl bead, and an aluminum slider are measured differently. A painted-shut sash should be named, not forced.
• An old single sheet can sometimes become a sealed unit if the sash is deep enough. Our single-pane guide is that limit.

The measure is a free in-home visit through Get A Quote. With over 15 years here, as a licensed and insured shop, we measure before the unit is made. Broken window repair is the path when the lite is already open.

Houses, suites, and who usually calls

In a house, the hung window or the slider is usually part of the home. Start on residential glass. The sash has to meet, and the glass has to be whole.

In a condo or a townhouse, the window may be common property, part of the unit, or shared in a way the bylaws spell out. That varies by building. This is not legal advice. If you are unsure, tell the manager before anything is ordered. Our strata page is where to begin. A wider list is the property manager checklist. A rental may limit who can book the work.

Broken glass after dark is our clocks-change post.

FAQ

Can I tape a hung or sliding window until the rain passes?

Tape can mark a crack and keep a small piece from dropping. It does not pull a sash into the frame. Close it from inside if the handle will finish. If there is a hole, cover it and call.

Does fogged sash glass have to be replaced before the next storm?

Fog alone can usually wait for a booking. A sash that will not close, or a crack that has opened a hole, should not wait through a multi-day rain.

Will new glass stop a leak at the meeting rail?

Often, only when the water was coming through a broken pane or at a failed edge. A gap at the lock, with clear glass, can remain after a new unit.

Who arranges a hung or sliding window in a strata building?

Bylaws vary. The pane may be common property or part of the unit. This is not legal advice. Ask the manager before glass is ordered if you are unsure. A photo is enough to start.

Ready to check the hung and sliding windows before the next rain?

A sash that locks on a dry afternoon is the useful check this week. Fog can be booked. A hole should not wait for the next dry hour. New glass belongs in a sash that can still meet the frame.
