Window mastic for homes and businesses in East Stratton
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. If you are dealing with draughts coming in around windows and doors and gaps left after new windows were fitted, we can help, on aluminium frames, uPVC windows and window sills alike.
Somewhere as small as East Stratton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months.

Common questions in East Stratton
Can you do window mastic in East Stratton?
Yes, East Stratton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is East Stratton within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How much does window mastic cost in East Stratton?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
What window mastic looks like in East Stratton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Micheldever station, 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 All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Clean frames with a soft cloth and soapy water
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Why act early in East Stratton
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a small place like East Stratton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.
