Double Glazing Repairs in Maidstone

Maidstone’s homes range from Victorian terraces near the town centre to 1930s semis and newer estates on the edge of town. These are the repairs we carry out most.

Misted windows

Fogging between the panes means the seal has gone. We replace the sealed unit in the existing frame, usually on a second visit once the new glass has been made to measure.

Sticking and draughty windows

Sashes that drop, catch on the frame or let in draughts often just need new hinges, new gaskets or a proper adjustment.

Door repairs

uPVC and composite doors realigned, multipoint locks replaced and cylinders upgraded to anti-snap.

Broken glass

Cracked or smashed panes made safe and replaced with the right safety glass for the position.

Repair or Replace?

A good rule of thumb: if the frames are square, solid and not discoloured, repair makes sense. New glass units, hinges and seals bring most windows back to life for a fraction of the cost of replacements.

If the frames are warped, cracked or leaking at the joints, or you still have single glazing, new windows will cut your heating bills and last far longer. We are happy to look and give you both prices so you can decide.

Answer a few quick questions — see a price range in under a minute. Guide estimate only — more options available.

1) Tell us about your home

This helps us pre‑fill the typical number of windows for your home.

2) How many windows would you like replaced?

We’ll pre‑fill an average based on your home type — change it if you know the exact number. Guide estimate only.

3) Window style & glazing

Double glazing is the UK standard. Triple improves insulation and noise reduction.
A sash window slides up/down (common in period homes). Only count the ones that are sash.
uPVC = low maintenance and great value. Aluminium = modern and durable. Timber = heritage character.

4) Doors (choose any that apply)

Select only the door types you’d like included. We’ll explain each option below.
French doors are side‑hinged double doors — classic look and wide opening.
Sliding doors save space and give a large glass area.
Bifolds concertina fully to open your space up to the garden.

Almost done — where should we send your estimate?

Window Repair Questions from Maidstone

Do you cover all of Maidstone?

Yes, including Allington, Bearsted, Boxley, Penenden Heath, Tovil, Barming, Shepway and Park Wood, as well as nearby Aylesford and Larkfield.

Is it worth repairing old double glazing?

Often, yes. If the frames are sound, replacing failed glass units and worn hinges can give your windows years more life for far less than new ones. If the frames are past it, we will tell you.

How does a misted unit replacement work?

We measure on the first visit, the new sealed unit is made to size, and we fit it on a single return visit. Your existing frame stays in place.

Are new windows guaranteed?

Yes. New windows and doors come with a 10-year insurance-backed guarantee, and as a Certass registered installer we register the work for building regulations.
