Sand mastic in Towersey: 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 Adwell House (about 4.2 miles south-west) nearby, there’s older building stock in the area around Towersey 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.
In the older streets around Church of St Catherine, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Haddenham & Thame Parkway station, any sash windows need sound mastic to keep draughts and rain out.
Towersey is about 1 mile east of Thame, in Oxfordshire. Anywhere in OX9, our applicators can take on sand mastic. Towersey is one of 443 towns and villages in Oxfordshire we cover. For nearby work, see our Oxford page, about 13 miles away.

Sand mastic in Towersey, done properly
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on tenement windows, brick reveals and stone surrounds, and the jobs we see most are window mastic to renew ahead of painting and weathered mastic on the most exposed windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Towersey is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What we are called out for in Towersey
Timber frames move with the seasons. The movement cracks the mastic over time.
The most common problems we see are:
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
Managing a site like Lord Williams's School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Towersey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask about the job first.

How the job changes by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracked or broken glass
- Timber that has rotted
- Sashes that need overhauling
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Period & listed homes

- Stone surrounds
- Timber door frames
- Brick reveals
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. In a small place like Towersey, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Advice
Towersey: your questions answered
Do you cover smaller places like Towersey?
Yes. Towersey is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Haddenham & Thame Parkway station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
