Ten door and window symptoms, from failed locks and broken glass to fogged panes and drafts. Learn when to call for urgent help and when to arrange an assessment.
At a glance
- Broken glass and openings that will not lock need urgent attention.
- Sticking, drafts and worn hardware are reasons to arrange an assessment.
- Describe the symptoms and send photos only if it is safe.
The urgency of a door or window problem depends on the condition of the opening and whether people or property are at risk. These ten symptoms are not a strict ranking: a failed lock, damaged glass or an unsafe exit needs prompt attention wherever it appears on the list. If you are unsure whether an opening is safe or secure, call before continuing to use it.
- The door will not lock or latch at all. If the door cannot be secured, do not wait for a planned maintenance visit. Do not force the lock or door. Door repair covers latch, strike and lock-alignment problems, with immediate emergency dispatch available 24/7 for an unsecured property.
- Glass is cracked or shattered. Keep people away and do not touch or measure it. We can dispatch immediately to assess the damage and secure the property. Glass replacement may follow on the same visit or after fabrication, depending on the size and glass specification.
- The frame is split or the jamb has separated from the wall. Visible frame damage can affect the support for hinges or locking hardware. A working lock does not establish that the whole opening is sound. Keep clear of loose parts and arrange prompt assessment, especially after an impact or forced entry.
- A window will not close or lock securely. A stuck-open window can leave the property exposed to weather or unwanted access. Hardware, alignment or frame problems may be involved; a symptom alone does not identify the cause. Do not force or lean out of the window. Window repair covers stuck sashes, worn cranks and latches that no longer catch.
- You can feel a draft with your hand at the edge of a closed door or window. If the opening is otherwise intact and secure, book an assessment of the seals, alignment and surrounding installation. Weatherstripping or window caulking may be appropriate, but the source needs checking first. New water entry or visible damage changes the situation and deserves prompt attention.
- Moisture is trapped between the panes. Persistent fogging inside a sealed glass unit usually indicates a failed edge seal. This can affect visibility and thermal performance. If the glass is intact and the window is secure, arrange an assessment rather than treating fogging alone as an emergency.
- A commercial door closer slams, will not latch fully, or leaks fluid. Keep people clear of an entrance that is moving unpredictably and notify the person responsible for the building. Do not disable a closer or exit device to keep trading. A technician should assess the cause and decide whether adjustment, repair or replacement is needed. See door closers and push bars for these services.
- A sliding patio door has come off its track or will not slide. Stop operating a panel that has come off its track and do not try to lift or force it back into place. Call for urgent help if it is unstable or the opening cannot be secured. Patio door repair covers rollers, tracks and alignment; the work and number of visits depend on the condition and parts required.
- Several small problems appear together. A squeaking hinge and a sticking latch may have a shared alignment problem, or separate causes. Book an inspection before the damage gets worse. If the door or window cannot close or lock securely, call for urgent help.
- Anything that happened during or right after a break-in. Stay clear until it is safe to approach the property. Forced entry can damage the frame, glass or hardware even if the lock still operates. Arrange prompt assessment and immediate securing if the opening is unsafe or exposed. Once safe, keep photos and repair documents if you plan to make an insurance claim; your insurer decides coverage.
How to prioritize when more than one thing is wrong
People's safety comes first, including damaged glass, unstable doors or windows, and affected escape routes. An opening that cannot be secured or is letting severe weather in also needs urgent attention. Fogging alone or a minor draft can usually be assessed at a planned visit if the opening is otherwise sound and secure. Tell us the full list when you contact us so we can prepare for the assessment. Repairs and follow-up visits depend on the findings and parts needed.
