Frames and glazing around Poffley End
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Minster Lovell Hall (about 2.2 miles west) are a reminder that the area around Poffley End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Finstock station, any sash windows need sound mastic to keep draughts and rain out.

Sand mastic in Poffley End
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have gaps between timber frames and stone or brick and modern sealant on a period surround, we can help.
Homes in small places like Poffley End often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Do you need sand mastic in Poffley End?
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Common reasons people contact us are:
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Failed mastic on an exposed elevation
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like Hailey Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Which sealant they’ll use, and why
- What insurance they hold
- How the joint is cleaned and prepared
- Which colour the sealant will be
Keeping the joints in good condition
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Go gently near the mastic when preparing windows
- Don’t run silicone over sand mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Surface by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common questions in Poffley End
I let a flat near Finstock station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Poffley End for sand mastic?
Yes. Our work covers London and the South East, and Poffley End is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens if it’s left?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Older cottages and farmhouses around Poffley End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
