Window mastic for homes and businesses in Chitty
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on composite doors, aluminium frames and uPVC windows, and the jobs we see most are gaps where the sill meets the wall and mastic that’s falling out in pieces.
Mastic can only go onto a dry, clean joint, so window work in Chitty is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Chitty
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us are:
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
If you live in an older home near Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The product the joint needs
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Where the property is
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Whether it has been sealed before

Landlords, agents and businesses in Chitty
Landlords and letting agents in Chitty can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
How to look after the new joints
To keep the joints looking good and working properly:
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Don’t aim a pressure washer at the joints
- Ventilate rooms so frames don’t stay wet inside
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that’s a job for a joiner.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Chitty, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
Getting a quote
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details, and photos are welcome.

Chitty homes and the weather
Chitty is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Herne Bay station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Chislet Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Chitty questions
I let a flat near Herne Bay station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Chitty?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How many windows can you do in a day?
A handful of frames is a short visit. You will get a timescale with the quote.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you do upstairs windows?
Normally, yes. We plan safe access before the job.
Are you insured?
Yes. We are fully insured for every job we do.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why act early in Chitty
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Chitty, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
