Why act early in World's End
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like World's End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
Why World's End clients choose us
- Quality sealants from Arbo and Everbuild
- More than 20 years in sealant work

Common problems we fix in World's End
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The problems people generally mention when they call are:
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
Schools such as Beedon C.E. (Controlled) Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

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.
If you live in an older home near Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

World's End questions
Can you do sand mastic in World's End?
Yes. Our work covers London and the South East, and World's End is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Will you come out to World's End?
Yes, World's End is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or won’t open
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Find out about consent before window work on a listed home
- Sort the mastic before the decorators arrive
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
