Advice
How we quote for sand mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Access and height
- The number of rooms or windows
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.
What we need to know
To make quoting easier, let us know:
- Where the property is
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or email us.

Can you help a landlord with a rental near Newbury Racecourse station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Curridge within the area you cover?
Yes. Curridge 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.
Do you take out the old sealant first?

Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.

A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Where do you work from?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Frames and glazing around Curridge
The South East is one of the drier parts 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 Shaw House (about 2.5 miles south-west) nearby, there’s older building stock in the area around Curridge as well as newer homes. 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.
For landlords with property near Newbury Racecourse station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Curridge Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What we’re called out for in Curridge
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
If you can see any of these, it’s time to have the joints looked at:
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
In the older streets around Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs
