Sand mastic in Sarsden, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. Common call-outs are for old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick, across tenement windows, period & listed homes and brick reveals.
Outdoor sealant needs dry, clean surfaces, so work on frames around Sarsden is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our 12-month guarantee.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Sarsden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Chastleton House (about 4.3 miles north-west) are a reminder that the area around Sarsden 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’s traditional sand mastic.
Homes close to Church of St James include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Kingham station, any sash windows need sound mastic to keep draughts and rain out.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The number and length of the joints
- When we can work, for business premises
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Helping us quote
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the property is
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Signs you need sand mastic in Sarsden
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
It’s worth asking for a quote if you see:
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
Managing a site like Chipping Norton School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Very little: the area around the joints is protected first, and we tidy up before we go.
Do I have to be there?

What sealant do you use?

When it isn’t the sealant

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Sarsden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
