When to call us in Stockbridge
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Patchy fillers round a sash window
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
Homes close to Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle sand mastic in Stockbridge
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. Common call-outs are for gaps where the frame meets the masonry and failed mastic on an exposed elevation, across sash and case windows, timber door frames and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Stockbridge is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a one-year guarantee.

Sand mastic in Stockbridge: local notes

Quotes for sand mastic in Stockbridge
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows

- The type of sealant required
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that’s easy
- Roughly how big the job is
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking

Your questions about sand mastic in Stockbridge
Is sand mastic in Stockbridge guaranteed?
All our work, in Stockbridge and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Stockbridge for sand mastic?
Yes, Stockbridge is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
When something else is needed
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Broken panes
- Sashes that rattle, stick or won’t open
- Whether work needs listed building consent
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Tenement windows
- Timber door frames
- Brick reveals
- Stone surrounds
- Period & listed homes
- Sash and case windows
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Stockbridge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. For a village or hamlet like Stockbridge, 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.
