Impact Windows & Doors Stopped Working

If your impact window or door has stopped latching, won’t open or close, is letting in air or water it shouldn’t, or the glass looks different than it did yesterday, you are most likely dealing with one of four problems: a failed seal, a hardware failure, frame movement, or – in rarer cases – glass delamination. None of these fix themselves, and some of them get worse the longer the opening stays compromised.

Impact-rated windows and doors are engineered to a higher performance standard than standard residential glazing. The laminated glass, the reinforced frames, and the multi-point locking hardware all have to work together for the system to do what it was rated to do. When one component fails, the window or door may still look intact from the outside – which is exactly why homeowners don’t always catch it until they notice a draft, a rattle, or condensation that wasn’t there before. A visual check on the inside, around the frame and the sash, tells you more than a look from the street.

Why It Happens

Failed Insulating Glass Seal

The insulating glass unit in an impact window is sealed at the factory. Over time – especially on west- or south-facing openings that take daily heat cycles – that seal can fail. When it does, the argon or air between the panes escapes, and moisture enters. The clearest sign is condensation between the panes that you cannot wipe away, or a hazy, milky look to the glass that comes and goes with temperature. The glass itself is still intact; it’s the sealed unit that’s done.

Hardware Wear or Misalignment

Multi-point locks, espagnolette bolts, and the compression hardware on impact doors are mechanical systems. They wear. A door that used to latch smoothly and now requires extra force to close, or a window where the handle turns but nothing engages, almost always points to worn or misaligned lock hardware. You might also hear a grinding or clicking sound when you operate it – that’s the mechanism dragging on a surface it used to clear cleanly.

Frame Movement or Settlement

Houses move. Concrete settles, wood framing swells and dries seasonally, and the rough opening that was square when your windows were installed may not be perfectly square now. When the frame shifts even a few millimeters, the sash or door panel can bind, gap at a corner, or refuse to seat against the weatherstrip. Look at the gap between the sash and the frame all the way around – if it’s noticeably uneven, or if daylight shows through one corner, the opening has moved.

Weatherstrip and Gasket Failure

The perimeter gaskets and weatherstripping on impact windows and doors take constant compression from every open-and-close cycle, plus UV exposure and heat. When they degrade, you’ll notice it as a draft on a calm day, wind noise that wasn’t there before, or water intrusion at the sill during heavy rain. Press your hand along the closed frame perimeter on a windy day – if you feel air movement, the gasket seal has broken down. This is the most common cause of air and water infiltration complaints we hear.

What to Do Right Now

• Stop forcing it. If the window or door is binding, do not keep trying to operate it. Forcing a misaligned frame can crack the glass unit, strip the lock mechanism, or warp the sash. Leave it in the last position that worked without resistance.
• Photograph the problem area. Take a photo of the gap, the condensation, the hardware position, or wherever you first noticed something was wrong. Do this before you touch anything. That photo becomes part of your job record if you book a visit – it’s also what helps a technician arrive with the right parts the first time.
• Check the obvious first. On sliding impact doors, check whether something is in the track. On casement windows, check whether the crank arm has disengaged from the sash shoe – it’s a small metal clip that can pop loose and is sometimes visible without tools.
• Do not attempt to adjust the frame yourself. If you suspect the frame has moved or shifted, leave it alone. Shimming, planing, or trying to re-square a load-bearing rough opening without understanding what’s behind the wall is a way to make a small problem structurally significant.
• If the glass is visibly cracked, chipped, or delaminated, keep people back from it. Laminated impact glass is designed to hold together when broken, but a compromised pane is still a compromised opening. If you can see damage to the glass itself – not just between the panes – treat the area as you would a broken window until a technician has assessed it.

How We Fix It

When your local Sightline Windows & Doors team arrives, the first thing that happens is a documented survey – measurements, photos, and a written account of what we actually found. That survey is yours to keep; it’s also the document your written price comes from, so the number cannot move between the assessment and the repair.

For hardware failures, most lock mechanisms and compression systems can be replaced at the opening without removing the full frame, and the job is typically completed in a single visit. Failed insulating glass units require a replacement sealed unit – the frame stays, only the glass is swapped. Frame movement or gasket failure usually means a combination of re-sealing, re-shimming, and replacing perimeter gaskets.

The services that resolve these issues fall under our Impact Windows & Doors and Window Replacement categories, depending on what the survey finds. Every repair is covered by the 365-Day Done Right Promise, written into the Haven Standard – not a verbal assurance. If it’s not right within that period, we make it right. Your written price comes before any work starts, always. That’s Clause 1 of the Haven Standard, and it has applied to every one of the 18,000+ windows and doors we’ve installed since 2012.
