Booked Glazing Repairs in Harrow | Windows & Doors
London Glazing provides mobile window and door glazing repairs at homes and commercial premises in Harrow. This page is for arranging non-urgent visits, including assessment of misted double-glazed units, damaged glass and windows that no longer operate properly. We visit the property; we are not a walk-in glass shop or a supply-only glass-cutting counter.
Call 07949 775317 with the full postcode and a description of the fault. Explain whether the window is secure and whether it can close without being forced. We will discuss the assessment and access needed before agreeing the next step.
Which glazing problems need assessment?
- Misting between double-glazed panes: describe where the condensation appears, rather than assuming the whole frame needs replacement.
- Cracked or damaged glazing: keep clear of the glass and tell us whether the opening is secure.
- Stiff handles, hinges or windows that catch: do not force the mechanism; describe what moves and where it sticks.
- Draughts or water around a window: explain when the problem occurs, as the cause may involve the seals, frame or surrounding installation.
The repair depends on the condition of the frame, hardware and glazing. A replacement sealed unit may be suitable in an existing frame, but that decision needs assessment. Made-to-measure glass may require a separate fitting visit after specification and manufacture.

Plan a glazing visit to your Harrow property
For flats near Harrow-on-the-Hill or properties around Wealdstone, give the full address and postcode when booking rather than relying on the area name alone. Explain the floor level, entry-phone arrangements and whether a caretaker or managing agent must provide access.
At town-centre shops or offices, tell us about opening hours, delivery access and any restrictions on work beside a public footway. A keyholder who can authorise the work should be available. Mention loading restrictions before the visit; do not obstruct pavements or reserve unsafe access.
What to send before an assessment
- A description of the affected window or door, its frame material if known, and the number of units involved.
- Photographs taken from a safe position, showing the fault and the surrounding frame. Do not remove glass or lean outside to obtain pictures.
- Any known access constraints, such as stairs, lift size, narrow passageways or furniture close to the opening.
- Details of who can approve the work and provide access, especially for rented or managed premises.
Photographs help explain the problem but do not establish a final glass specification. Do not dismantle a window or measure damaged glass yourself. Tell us about any visible glass markings only if they can be read safely.
Older frames and managed buildings
If the property has older timber windows, decorative glass or restrictions on changes to its appearance, mention this when booking. Check any landlord, lease or planning requirements that may apply before authorising a change. An assessment does not replace any consent the property needs.
For communal doors and shared areas, coordinate with the responsible building manager. Tell us if the fault affects a shared entrance or escape route, so the access and safety implications can be discussed before attendance.
When the problem cannot wait
If glass has broken and the opening is exposed, keep people and pets away. Do not pull out loose shards or force a damaged frame. Our Harrow emergency glazing page explains urgent assessment and temporary boarding; boarding is not a completed permanent repair.
See our service-area information for wider coverage. Harrow is an area we visit, not a claim of a local branch. Call 07949 775317 to discuss a booked mobile repair and the information needed for your property.
