Double Glazing Repairs in Sittingbourne

Sittingbourne mixes Victorian terraces near the town centre and Milton Regis with large newer estates at Kemsley and Iwade. These are the jobs we do most often here.

Misted double glazing

A foggy window means the seal on the glass unit has failed. We replace the sealed unit and keep the frame, which is the most cost-effective fix.

Side and landing windows

Side windows, landing windows and small bathroom windows often get left until last. We replace single glass units or whole windows, with obscure or toughened glass where it is needed.

Door and lock repairs

Front and back doors that drop, stick or will not lock usually need a hinge adjustment or a new multipoint mechanism. More on our door repairs page.

Older timber windows

Where a timber frame is still sound we can repair it. Where it is not, we replace it with uPVC or aluminium and explain the options first.

Keeping Newer Homes’ Windows in Shape

On newer estates such as Kemsley and Iwade, the windows themselves are usually sound, but hinges, handles and door alignment need attention after a few years of daily use. A service visit to adjust and lubricate everything can prevent a bigger repair later.

What Happens When You Call Us

Tell us what the problem is, ideally with a photo, and we can often give you a rough idea of cost straight away. We then visit to check the window or door, confirm the price and carry out simple repairs there and then. Glass units and specialist parts are made to measure and fitted on a return visit, and we leave everything clean and tidy.

Not sure what is wrong? Send us a photo.

Fill in our quick enquiry form and attach photos of the problem, or WhatsApp your photos to 01634 944 243. Many repairs can be priced from photos alone, so you may not even need a visit to get a price. Every quote is free.

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.
