Window mastic in Hook
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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you’re dealing with leaking joints at the ends of sills and white mastic on grey or black frames, we can help.
In a village or hamlet like Hook, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Hook and everywhere else we cover.

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Hook can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Signs you need window mastic in Hook
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Look out for any of the following:
- Mastic that’s falling out in pieces
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes most of a day for a typical house, less for a few frames. In a small place like Hook, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

When it is not the sealant
A few problems are outside what sealant work can do:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.

Common questions in Hook
Is window mastic in a coastal place like Hook any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Hook?
Yes. Hook is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What does window mastic cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
Can you reach windows above the ground floor?
Normally, yes. We plan safe access before the job.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Hook homes and the weather
Hook 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Swanwick station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Locks Heath Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
