Sand mastic in The Common
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are old cement repairs round a window that have failed and weathered mastic on the most exposed windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around The Common is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee.

Windows and doors in The Common
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Radwinter Church of England Voluntary Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
The Common is about 4 miles east of Saffron Walden, in Essex. We carry out sand mastic for homes and businesses in The Common and the surrounding area, as part of our work across Essex. We cover 644 towns and villages across Essex. For nearby work, see our Chelmsford page, about 21 miles away.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
Common problems we fix in The Common
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
Signs it’s time to call us include:
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Cracked mastic round a front door frame
- Open joints round the window box
If you live in an older home near Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- How the colour is chosen
- What the cure time is
- Whether they seal over old material or remove it
- Who turns up on the day

The Common questions
Do you cover The Common for sand mastic?
Yes. We work across London and the South East, and The Common is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is there a guarantee on sand mastic in The Common?
All our work, in The Common and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a small place like The Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

- The amount of work
- Which sealant suits the joint
- How many rooms, windows or areas are involved

Every job is a little different, 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.

- Access, such as stairs, a lift or height
- Photos by email, if that is easy

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. For a village or hamlet like The Common, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
