Frames and glazing around Neames Forstal
Historic houses like Belmont House and Gardens (about 4.1 miles west) are a reminder that the area around Neames Forstal 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. 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.
If you let a flat or house near Selling station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How we handle sand mastic in Neames Forstal
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you are dealing with failed mastic on an exposed elevation and a silicone bead on a sash window that spoils the look, we can help, on tenement windows, timber door frames and sash and case windows alike.
Somewhere as small as Neames Forstal, 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.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Neames Forstal questions
Do you work for landlords with property near Selling station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Neames Forstal within the area you cover?
Yes, Neames Forstal is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How much does sand mastic cost in Neames Forstal?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- 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.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Decayed frames that need repair
- Broken panes
- Decisions on consent for listed homes
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
