Sand mastic in Little Dunmow
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We’re often asked to deal with a silicone bead on a sash window that spoils the look and mastic worn away on windows facing the weather, across brick reveals, stone surrounds and period & listed homes.
Around Little Dunmow, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same one-year guarantee.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Do you need sand mastic in Little Dunmow?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- A silicone bead on a sash window that spoils the look
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- Open joints round the window box
Homes close to Church of St Mary the Virgin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes a few hours per window, depending on the condition of the joints. In a smaller place like Little Dunmow, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at the surrounds with you and agree the joints to renew.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Keep children and pets away from the work area

Why it’s worth doing now in Little Dunmow
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Little Dunmow, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
