Sand mastic for homes and businesses in Little Burstead
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Common call-outs are for draughty sash windows at the surround and old cement repairs round a window that have failed, on tenement windows, brick reveals and stone surrounds.
Somewhere as small as Little Burstead, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere as small as Little Burstead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can

How long will you be here?

Do you hold any approvals?

Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Sand mastic in Little Burstead: local notes
With historic houses such as Ingatestone Hall (about 4 miles north) nearby, there’s older building stock in the area around Little Burstead as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Billericay station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as South Green Junior School, the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Little Burstead
Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Around Little Burstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
