Window Mastic in Butcher's Cross
Window and door frames in Butcher's Cross need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- A bead that doesn’t match the frame
- Hard, cracked sealant around windows
- Water coming in at the bottom corners of a door
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
Surfaces we seal
- Aluminium frames
- Timber windows & doors
- Window sills
- Composite doors
- Patio & French doors
- uPVC windows
Window mastic for homes and businesses in Butcher's Cross
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have damp patches on the reveal after heavy rain and cracked internal joints between frame and plaster, we can help, on aluminium frames, uPVC windows and composite doors alike.
Mastic can only go onto a dry, clean joint, so window work in Butcher's Cross is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why deal with it now?
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Butcher's Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Butcher's Cross questions
Can you do window mastic in Butcher's Cross?
Yes. We work across London and the South East, and Butcher's Cross is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do you work for landlords with property near Crowborough station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Frames and glazing around Butcher's Cross
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Skippers Hill Manor School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Crowborough station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of the Good Shepherd, the joint between an old wall and a newer frame is generally the first place rain gets in.

Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as a joiner will need to deal with it.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
