Window mastic in Windmill Hill, done properly
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, composite doors and uPVC windows, and common reasons people get in touch are a bead that doesn’t match the frame and rushed sealant from a window installation.
Around Windmill Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Windmill Hill
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- The number of rooms or windows
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Windmill Hill: your questions answered
Is Windmill Hill in your area for window mastic?
Yes. Our work covers London and the South East, and Windmill Hill is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
I let a flat near Normans Bay station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How many windows can you do in a day?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Frames and glazing around Windmill Hill
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Horselunges Manor (about 4 miles west) nearby, there’s older building stock in the area around Windmill Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Herstmonceux Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Normans Bay station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep solvents and bleach off the sealant
- Use gentle cleaners on frames and sealant
- Check the mastic once a year
- Repaint timber before it’s bare
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or email us.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Common problems we fix in Windmill Hill
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
The problems people usually mention when they call include:
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
Historic houses such as Horselunges Manor, about 4 miles west, show how far back building around Windmill Hill goes, and older homes nearby need a sealant that suits their walls.

How it works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on how much there is to do. Somewhere as small as Windmill Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
