Compare Bay Window Quotes in Gillingham
From Victorian terraces to inter-war semis, plenty of Gillingham homes have a bay at the front, and replacing one is a bigger job than it looks. Before any frames come out, someone needs to work out what the bay is holding up.
Send a short description of the bay window and Kent Windows will pass your enquiry to independent installers covering Gillingham, Kent. If suitable firms have space in their diaries, as many as four could offer a survey and quote. There is no cost and no commitment.
Types of Bay Window
Canted bays, with angled sides, are the classic Victorian shape, while a square bay has sides at right angles to the house. A bow is made from a series of narrow frames joined at small angles to form a curve.
Most replacements match the existing shape and angles, but some owners take the chance to change the style or opening arrangement.
Signs Your Bay Needs Attention
- Cracks at the corners of the bay or where it meets the house
- A leaking bay roof dripping into the window head
- Rotten timber corner posts or mullions
- uPVC frames that have sagged so the openers bind
- Cracked plaster above the bay inside the room
If the brickwork around the bay is cracking, mention it in your enquiry.
At the survey, ask the fitter to show where the temporary props will stand. A sound new frame still needs the load path, corner joints and weatherproofing around the bay roof to be dealt with together.
What to Expect
- First visit: the lintel, brick base and load above are assessed and every section and angle measured.
- Support plan: bay poles, load-bearing couplers or a new lintel are chosen to carry the weight.
- Ordering: each section and corner joint is made to size, typically over several weeks.
- Removal: the structure above is propped while the old frames come out.
- Installation: new sections go in with the agreed supports, then are sealed, glazed and trimmed before props come out.
Most bays are fitted in a day, but two-storey bays and those needing a new lintel can take longer.
Structural Details to Agree for Your Gillingham Bay
Ask each installer exactly how the load will be carried. uPVC frames are not designed to support a roof or wall, so where old timber posts were doing that job, something has to replace them. Ask whether an engineer's calculation is needed and whether it is included.
Agree who repairs the bay roof, lead and render if they are disturbed. Internal features matter too: window seats, radiators and curtain tracks fixed into the bay head all need planning.
Bay Window Prices in Gillingham
The guide range for bay windows is £1,700–£6,500. The lower end covers a modest single-storey canted bay, while a two-storey bay or one needing a new lintel sit toward the top. Treat the range as a guide until the bay has been surveyed.
Find out whether the quote covers VAT, bay poles or lintels, scaffolding, bay roof repairs and making good.
Rules to Check First
Replacing a bay with one of the same size and similar appearance is usually permitted development on a house. Enlarging it, changing its shape noticeably, or working on a listed building or in an Article 4 conservation area may need consent. Check with Medway Council.
Structural work to the bay may need building control approval beyond what a competent person scheme covers, so ask your installer how the job will be signed off. The Planning Portal's windows guidance summarises the rules.

Your Bay Window Questions Answered
How much does a bay window cost in Gillingham?
The guide range is £1,700–£6,500 for a single bay assembly. Two-storey bays, timber frames and structural repairs can cost more.
Why does a uPVC bay need extra support?
uPVC frames are not built to carry structural loads. Where a bay supports a roof or room above, bay poles, load-bearing couplers or a lintel take the weight instead.
Can a bay window be replaced in one day?
Most single-storey bays are replaced in a day. Two-storey bays or those needing a new lintel may take two days or more.
Do I need planning permission for a new bay window in Gillingham?
A bay of the same size and shape on a house normally falls under permitted development. Enlarging the bay, listed buildings and Article 4 conservation areas may need consent.
