Sand mastic in Spelsbury, done properly
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We’re often asked to deal with a silicone bead on a sash window that spoils the look and mastic dropping out of the joint, on brick reveals, sash and case windows and timber door frames.
In a village or hamlet like Spelsbury, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, 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 ring 0345 464 0079 or drop us an email.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a small place like Spelsbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Spelsbury: your questions answered
Can you help a landlord with a rental near Charlbury station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is Spelsbury within the area you cover?
Yes, Spelsbury is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We will give you a better idea when we quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Do you need sand mastic in Spelsbury?
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Common reasons people contact us include:
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Windows and doors in Spelsbury
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Chadlington Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Charlbury station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
So the new joints stay in good condition:
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What we can’t put right
Before booking, it’s worth knowing the limits:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Decisions on consent for listed homes
- Cracked or broken glass
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Can I do it myself?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
On the day, there’s very little for you to do. 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 from start to finish. In a small place like Spelsbury, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Advice
Different surfaces, different methods
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
