Sand Mastic in Kingham
Professional sand mastic in and around Kingham, with old sealant always removed completely and a one-year guarantee.
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
- Avoid heavy scraping on the mastic joint
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic for homes and businesses in Kingham
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We are often asked to deal with modern sealant on a period surround and open joints round the window box, across sash and case windows, tenement windows and stone surrounds.
In a village or hamlet like Kingham, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee.

Leave it or put it right?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Kingham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Landlords, agents and businesses in Kingham
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
What affects the quote in Kingham
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- The number and length of the joints
- Working hours on commercial sites
- The number of rooms or windows
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear quote.
Do you need sand mastic in Kingham?
Timber frames move with the seasons. The movement cracks the mastic over time.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Draughty sash windows at the surround
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
If you let a flat or house near Kingham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before booking
- How the colour is chosen
- Are they insured?
- How the joint is cleaned and prepared
- What the cure time is
Windows and doors in Kingham
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 Chastleton House (about 3.3 miles north) are a reminder that the area around Kingham has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Kingham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

How long will you be here?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Planning or listed building consent (your local planning authority decides)
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Period & listed homes
- Brick reveals
- Stone surrounds
- Sash and case windows
- Tenement windows
- Timber door frames
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several in most cases. Somewhere as small as Kingham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
