About our sand mastic in Hyde End
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with silicone on a period window that looks wrong and draughty sash windows at the surround, we can put it right, on sash and case windows, period & listed homes and timber door frames alike.
In a village or hamlet like Hyde End, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same 12-month guarantee.

Hyde End homes and the weather
Historic houses like Cholesbury Manor House (about 3.7 miles north) are a reminder that the area around Hyde End has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Cholesbury Manor House, about 3.7 miles north, is one of the historic houses in the wider area around Hyde End. If you look after a building such as Hyde Heath Infant School, its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Hyde End

Yes, Hyde End is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Hyde End?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is it possible to take out silicone and use sand mastic instead?
Usually, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
How to look after the new joints
After the cure time, these simple habits help:
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Clear gutters so water doesn’t pour onto the windows
- Get any rot dealt with first
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

What the job involves on each surface
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.

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.
