Sand mastic in Oxted
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, brick reveals and stone surrounds, and the jobs we see most are weathered mastic on the most exposed windows and cracked mastic round a front door frame.
Homes around Oxted range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Sand mastic in Oxted: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Titsey Place (about 2 miles north-east) nearby, there’s older building stock in the area around Oxted as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around St Agatha's Hall, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Hazelwood School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Hurst Green station? Then any sash windows need sound mastic to keep draughts and rain out.

Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Oxted, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What affects the quote in Oxted
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
To help us quote quickly, let us know:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If someone has resealed it before
- Where the job is, and your postcode
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Different surfaces, different methods
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes a few hours per window, depending on the condition of the joints. In a smaller place like Oxted, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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 isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Tell us if parking is tricky
