What to do if…
a window will not close and cold air or rain is coming in
Short answer
Make the area safe first, then do a quick temporary seal (plastic/tape/towels) and report it immediately to whoever is responsible for repairs (landlord/agent/council or housing association) so it can be fixed properly.
Do not do these things
- Don’t lean out of the window or climb onto a sill/roof to “pull it shut” (falls happen fast).
- Don’t force the frame hard, slam it, or keep cranking a handle if it’s resisting (you can crack glass or strip the mechanism).
- Don’t use candles/open flames or any unvented fuel-burning device to “dry the rain out” or “warm the room” (higher fire and carbon monoxide risk).
- Don’t leave the window unsecured overnight if it’s reachable from outside (treat it like an unlocked door).
- Don’t agree to pay for permanent repairs on the spot if you’re a tenant (pause and contact the responsible party first, unless there’s an immediate safety hazard).
What to do now
-
Make it safe and reduce risk.
Keep children/pets away, move furniture and anything electrical out of the splash zone, and put a towel/bucket down if water is coming in. If there are sparks, water entering a socket, or a strong burning smell, keep clear of the area. If you can safely reach your consumer unit/fuse box (dry hands, dry floor), switch off the circuit for that room (or the main switch if you’re unsure) and get help. -
Check for the simplest “no-tools” fix (30–60 seconds).
- Remove any obvious obstruction in the track (grit, a folded blind, a displaced insect screen).
- If it’s a casement/uPVC window: gently press the sash into the frame while turning the handle once (don’t keep forcing).
- If it’s a sash window: check if a lock/catch is stuck in the “on” position.
-
Do a temporary weather seal from inside (aim: stop rain/draught, not perfection).
- If rain is coming in: tape a thick plastic bag, bin liner, or plastic sheet over the gap on the inside (tape to the frame/wall).
- If it’s mostly cold air: roll towels/clothes into a tight “draft sausage” and wedge firmly along the bottom/side gap.
- If you have it, wide packing tape/duct tape plus plastic works best short-term.
If the room contains a fuel-burning appliance and you’re unsure about ventilation needs, avoid running it in that room and don’t completely seal the room airtight.
-
Secure the home.
Close internal doors to that room and keep valuables out of view. If you have a sliding window/door that won’t secure, placing a rigid bar/dowel in the track inside can help stop it opening further. For other window types, focus on keeping the room closed off and reporting the security risk. -
Report it immediately to the right place (this is the “real fix” step).
- If you rent (private): contact your landlord/letting agent in writing (text/email is fine) and also call if it’s raining or very cold. Say: “Window won’t close; rain/cold air entering; security risk; needs urgent repair.”
- If you rent from a council/housing association: use their repairs line/portal and describe it as a security/weather-ingress issue.
- If you own: contact a local glazier/window repair service; if there’s storm damage or broken glass, your home insurer may have an emergency repairs line.
-
Document the situation quickly.
Take 3–5 photos: the gap, any water ingress, the handle/hinge area, and a wide shot of the room. Note the time you reported it. This helps if there’s later dispute about damage. -
If you’re being ignored and it’s affecting health/safety, escalate.
If the problem creates a serious hazard (very cold, ongoing water ingress, security risk) and your landlord doesn’t respond, contact your local council housing standards / Environmental Health (private sector housing) team and ask about an inspection for housing hazards.
What can wait
- You do not need to decide today whether to claim on insurance, replace the whole window, or start a formal complaint—focus on temporary protection + reporting.
- You do not need to perfectly dry the room right now; stopping further water and preventing electrical hazards is the priority.
- You do not need to negotiate costs or liability in the moment—get the repair process moving first.
Important reassurance
This is a common failure (handles, hinges, warped frames, stuck catches) and most situations become manageable once you’ve stopped the rain/draught and secured the room. You’re not “overreacting” by treating it as urgent—weather ingress and security gaps can cause fast damage.
Scope note
This is first-step guidance to stabilise the situation. Permanent repair/replacement decisions (and any disputes) can be handled once you’re warm, dry, and the immediate risk is under control.
Important note
This is general information, not legal or professional advice. If there’s immediate danger (e.g., structural instability, live electrical contact, suspected gas leak or carbon monoxide concern), prioritise emergency help.
