Double glazing repair in Upminster
Upminster window repair specialists - misty, blown & cracked glass fixed
If a window in your Upminster home has gone misty, cloudy or cracked, you almost never need a full replacement. In around 95% of the jobs we do across RM14, only the sealed glass unit has failed - the uPVC, aluminium or timber frame is still perfectly sound. Swapping just the glass typically saves Upminster homeowners £200-£500 per window compared to a full frame replacement, and the job is done in a single visit.
We're a family-run glazing firm based in Basildon with 30+ years of experience covering East London. Our engineers work Upminster routes weekly, so surveys are usually booked within 48 hours and most misty or blown units are fitted the same week. Every sealed unit we install comes with a 25-year manufacturer guarantee against seal failure, plus our own workmanship guarantee on top.

The rest of what we do in Upminster
These jobs are booked on the same RM14 routes and the same lead times as our glass work. Prices below are indicative and fixed in writing before anything is ordered.
Handles & Hardware in Upminster
from £65 fittedWindow hardware takes a beating over the years - handles seize up, locks fail, and hinges wear out. These aren't just inconveniences; they're security vulnerabilities. ClearPane carries an extensive range of replacement handles, espagnolette locks, friction hinges, and locking mechanisms for all major uPVC and aluminium window systems. Most repairs are completed in a single visit, though some specialist locks may need to be ordered.
Handles, friction hinges and gearboxes are usually a single short visit. Multi-point door mechanisms cost more because the gearbox has to be matched to the existing door.
On the day
We carry the most common uPVC handle, hinge and lock patterns in the van, so a large share of hardware jobs are finished on the first visit.
To quote you
A close-up photo of the handle or hinge and, if you can see it, the brand name stamped on the mechanism.
What we typically find in Upminster
- Faulty espagnolette locks on RM14 uPVC sashes
Cat Flaps in Upminster
from £180 supplied and fittedInstalling a cat flap or pet door into a window or door panel requires precision cutting and proper sealing to maintain insulation and weatherproofing. ClearPane's glaziers have the specialist tools and experience to cut perfectly into glass panels and uPVC panels, fit your chosen pet door, and seal everything to professional standards. We supply and fit all leading brands including SureFlap microchip-activated doors.
The price covers a new sealed unit with the aperture cut at the factory plus the flap itself. Cutting an existing pane is not possible on toughened or sealed glass, which is why the unit is replaced.
On the day
We measure the existing pane, order a matching unit with the hole pre-cut, then swap the glass and fit the flap in one appointment.
To quote you
The make of flap you would like (or let us recommend one) and whether it is going in a door panel or a window.
What we typically find in Upminster
- Replacement of 1930s-style multi-light bay window sealed units
- Misty units in 1990s Cranham developments
Secondary Glazing in Upminster
from £320 per windowSecondary glazing involves fitting an additional slim-line window on the room side of your existing windows. It's the ideal solution when you can't or don't want to replace your current windows - particularly in conservation areas and listed buildings. Secondary glazing dramatically reduces noise (up to 80%), improves thermal insulation, eliminates draughts, and adds an extra layer of security. ClearPane supplies and fits high-quality secondary glazing systems from leading manufacturers.
Secondary glazing is priced per opening and depends on the frame width and whether you want a fixed, hinged or sliding panel. It is usually the only realistic option in listed or conservation-area properties.
On the day
We survey the reveal, make the frames to size, and fit internally with no disruption to the original window.
To quote you
Whether you are targeting noise, heat loss or both, and whether the property is listed or in a conservation area.
What we typically find in Upminster
- Replacement of 1930s-style multi-light bay window sealed units
- Misty units in 1990s Cranham developments
Emergency Board-Up in Upminster
from £95 call-outWhen a window is smashed, your home or business is exposed to the weather, opportunist thieves, and further damage. ClearPane provides a rapid same-day board-up service across Essex and East London, securing your property within hours. We carefully clear broken glass, fit cut-to-size exterior-grade plywood to the opening, and seal it weather-tight. This buys time to make an insurance claim, source the correct replacement glass, or simply sleep easy knowing your property is secure. Boarding is also fitted to commercial premises, shopfronts, and rental properties. Once your replacement glass unit has been measured, manufactured, and is ready to install, we return to remove the boarding and fit your new glass - all backed by our standard guarantee.
Board-up covers making the opening secure and weathertight. The replacement glass is quoted separately once we have measured the aperture.
On the day
We aim to attend the same day within our core Essex and East London area, secure the opening, then book the permanent glazing.
To quote you
The address, the size of the broken opening, and whether it is ground floor or above.
What we typically find in Upminster
- Replacement of 1930s-style multi-light bay window sealed units
- Misty units in 1990s Cranham developments

A local tip for Upminster homeowners
Upminster's original 1930s bays often used 1+1 (two narrow lights) or 1+2 (one wide, two narrow) divisions. We match those exact splits in modern sealed units so the kerb-appeal stays intact, rather than dropping in a single oversized pane.

FAQs
Window repairs in Upminster - your questions answered
How quickly can you repair a misty window in Upminster?+
Upminster (RM14) is inside our core service area, so most jobs are surveyed within 48 hours and fitted the same week. Single broken panes are usually treated as priority and can often be boarded up the same day.
Do you charge a call-out fee for quotes in Upminster?+
No. Quotes and on-site surveys in Upminster and the surrounding RM14 postcodes are completely free with no obligation.
Will I need to replace the whole window, or can the glass be repaired?+
In around 95% of jobs we see in Upminster, only the sealed glass unit needs replacing - the frame stays put. That typically saves £200-£500 per window compared with a full replacement.
Are your repairs in Upminster guaranteed?+
Yes. Every sealed unit we fit in Upminster comes with a 25-year manufacturer guarantee against seal failure, plus our own workmanship guarantee.
Which parts of Upminster do you cover?+
We cover the whole Upminster area including Cranham, North Ockendon, Corbets Tey, Hacton, Aveley border and Bulphan border, plus every street within the RM14 postcodes. If you're unsure whether your road is covered, just call or send us your postcode.
Do you only replace the glass, or can you fix the frame and locks too in Upminster?+
We do both. As well as sealed glass units, we replace failed hinges, handles, multipoint locks and espagnolettes on uPVC, aluminium and timber frames across Upminster. If your frame itself is sound, fixing the mechanism is almost always cheaper than a whole new window.
