Open aluminium bifold doors looking out onto a garden, fitted by Kent Window Wizard

What We Do in Whitstable

Coastal homes need windows and doors that cope with salt air and wind, and many owners want to make the most of a view. These are the jobs we do most here.

Replacement windows

uPVC and aluminium windows with good seals and drainage, made to measure for coastal homes. See our replacement windows.

Bifold and sliding doors

Open a lounge or kitchen onto the garden or the sea view with aluminium bifolds or a wide sliding patio door.

Front and back doors

Composite doors in colours from sage green to anthracite, with multipoint locks. See our door services.

Glass balustrades

Glass balustrades for balconies, roof terraces and raised decks, so you keep the view and stay safe. See our glass balustrades page.

Conservatories and warm roofs

Replace an old conservatory roof with a solid, insulated warm roof and use the room all year. See our conservatories and warm roofs page.

Larger repairs

Misted units across the house, stiff or dropped patio doors and hinges worn by sea air. We sort them together in one visit. More on double glazing repairs.

Seafront, Old Town and Suburbs

Whitstable runs from the fishermen’s cottages and narrow streets of the old town to seafront homes along Tankerton and Seasalter, and family houses and bungalows in Chestfield and Swalecliffe. Salt air is hard on hinges, locks and seals, so we check them carefully at the survey and recommend options that suit an exposed position.

How a Job Runs

It starts with photos or a phone call so we can give you a rough idea of cost. We then visit for a free survey, measure up and send you a written quote. Once you go ahead, everything is made to measure, and we fit it and leave your home tidy.

Instant Online Estimate

Get your free price estimate

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?

Questions from Whitstable

Which areas around Whitstable do you cover?

Whitstable town, Tankerton, Chestfield, Swalecliffe, Seasalter, Yorkletts and South Street, as well as nearby Herne Bay.

Do you fit glass balustrades for balconies?

Yes. We fit glass balustrades for balconies, roof terraces, decking and Juliet balconies, using toughened safety glass.

Can you replace my conservatory roof?

Yes. We replace polycarbonate and glass roofs with a solid warm roof, which makes the room far more comfortable through the year.

Will new windows cope with being near the sea?

Modern uPVC and aluminium windows do well on the coast. We check how exposed your home is at the survey and recommend the right seals and hardware.
