uPVC and Glazing: Fix the Unit, Keep the Frame

The double glazing industry loves selling whole new windows. Usually you do not need them. Multi Group repairs uPVC windows and doors and replaces failed glass units within your existing frames across London and Essex, which fixes the actual problem at a fraction of replacement cost, and we say plainly when full replacement genuinely is the better spend.

Misted and failed double glazing

When double glazing fogs up between the panes, the sealed unit has failed, not the window. We measure and replace just the glass unit, keeping your frames, typically days rather than weeks, and a fraction of new window cost. Upgrading to modern low energy glass at the same time is often worthwhile, and with minimum EPC standards tightening for rentals, it is a quiet efficiency win landlords bank while fixing a fault.

uPVC window and door repairs

Handles that spin uselessly, hinges that drop the sash, locks that need a wrestling match, seals that whistle in wind: nearly all of it is repairable. We replace hinges, handles, gearboxes, cylinders and gaskets, realign doors and sashes to close with a fingertip, and free up windows painted or swollen shut. It pairs naturally with our wider doors and locks service, one visit covering security and function together.

New windows and doors, when honesty demands it

Sometimes frames really are done: blown throughout, brittle, or simply thirty years old. Then we quote supply and fit of new uPVC and composite units, explain the options without the double glazing salesman theatre, and install with trims and seals finished properly, because a good window fitted badly is a bad window.

For landlords and blocks

Rental stock lives hard: misted units photograph terribly in listings, stiff windows generate tenant complaints, and failed seals leak heat. We batch glazing and uPVC repairs across portfolios, prioritise voids so relisting photos sparkle, and handle communal door closers and glazing for blocks through our communal maintenance schedules.

Frequently asked questions

My double glazing is misty inside. Do I need new windows?

Almost never. The sealed glass unit has failed and can be replaced within your existing frame, quickly and far more cheaply.

Can you fix a uPVC door that needs slamming to lock?

Yes, that is classic misalignment or a worn mechanism, and a repair visit usually restores fingertip closing the same day.

Do you upgrade glass for energy efficiency?

Yes, replacement units can be upgraded to modern low energy glass, a sensible move while the unit is out anyway.

Do you fit brand new windows and doors?

Yes, where repair is no longer honest value, with straightforward quotes and no showroom sales theatre.

Do you serve landlords across multiple properties?

Yes, batched repairs and glazing across portfolios with consolidated invoicing and priority for void periods.
