Sand mastic for homes and businesses in Burwash
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on timber door frames, tenement windows and sash and case windows, and people most often call us about old sand mastic that has cracked, crumbled or fallen out and wind and rain getting in round a sash window.
In a village or hamlet like Burwash, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
How it works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. In a small place like Burwash, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
How to get a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.

Why act early in Burwash
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Burwash, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.

Do you need sand mastic in Burwash?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Any of these means the joints need attention:
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
For landlords with property near Stonegate station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Burwash homes and the weather
Historic houses like Bateman's (about 0.8 miles south-west) are a reminder that the area around Burwash has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Burwash CofE School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near The Parish Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Do you have insurance?
Yes. Full insurance covers our work.
