Sand mastic in Burghclere, done properly
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We are often asked to deal with cracked mastic round a front door frame and failed mastic on an exposed elevation, on stone surrounds, period & listed homes and timber door frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Burghclere 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.

Different surfaces, different methods
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get any rot dealt with first
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How we quote for sand mastic
You will get a clear quote before work begins. It takes into account:
- Which sealant suits the joint
- The number and length of the joints
- Working hours on commercial sites
- Whether there’s mould to deal with
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, phone 0345 464 0079 or send us an email.
Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Burghclere, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Advice
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Burghclere.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What sand mastic looks like in Burghclere
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Highclere Castle (about 1.9 miles south-west) are a reminder that the area around Burghclere 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 is traditional sand mastic.
For landlords with property near Newbury station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Burghclere Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of the Ascension include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
