How we handle sand mastic in Upper Bush
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with failed mastic on an exposed elevation and window mastic to renew ahead of painting, we can help, on sash and case windows, timber door frames and brick reveals alike.
In a village or hamlet like Upper Bush, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. For a village or hamlet like Upper Bush, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Related advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Questions from Upper Bush
Is Upper Bush in your area for sand mastic?
Yes, Upper Bush is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Will you come out to Upper Bush?
Yes, Upper Bush is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How much does sand mastic cost in Upper Bush?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Where do you work from?
We work from Crawley. Our applicators cover Upper Bush, along with the rest of our area.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What we’re called out for in Upper Bush
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
These are the problems we’re asked about most:
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
For an older house near a landmark such as Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Sand mastic in Upper Bush: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Starkey Castle (about 1.4 miles south-east) are a reminder that the area around Upper Bush 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.
If you let a flat or house near Cuxton station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Cuxton Community Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

What’s near Upper Bush
Locally, jobs take us to homes and businesses close to Strood Academy and the streets around them. The closest station to Upper Bush is Cuxton station, about 1.2 miles east. Other landmarks nearby include Rochester Castle (3 miles east) and Six Poor Travellers House (3.1 miles east). Open spaces near Upper Bush include Ranscombe Farm and Gad's Hill.
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Upper Bush, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
