Sand mastic in Oxley Green: local notes
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. With historic houses such as Layer Marney Tower (about 2.3 miles north-east) nearby, there’s older building stock in the area around Oxley Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Kelvedon station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Thurstable School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How we handle sand mastic in Oxley Green
We work across Oxley Green renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on timber door frames, brick reveals and tenement windows, and the jobs we see most are gaps between timber frames and stone or brick and silicone on a period window that looks wrong.
Somewhere as small as Oxley Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Oxley Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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’ll have a clear quote before any work starts.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas

What the job involves on each surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Oxley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Oxley Green questions
I let a flat near Kelvedon station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is Oxley Green within the area you cover?
Yes. Oxley Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Is sand mastic better than silicone for my windows?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
How long does sand mastic take to harden?
Not right away. It skins first and hardens fully later, and we’ll tell you what to expect.
How long will you be here?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We’ll confirm how long when we quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
