Sand Mastic in Chobham
Our applicators work in Chobham on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Silicone on a period window that looks wrong
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
Sand mastic in Chobham, done properly
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. If you are dealing with wind and rain getting in round a sash window and mastic worn away on windows facing the weather, we can help, on stone surrounds, period & listed homes and timber door frames alike.
In a smaller place like Chobham, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
Whatever the size of the job, you get the same 12-month guarantee in Chobham and across Surrey.

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Putty and glazing repairs
- Sashes that rattle, stick or won’t open
- Rotten sashes, sills or window boxes (a joiner’s job)

Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
- Old cement repairs round a window that have failed
If you let a flat or house near Longcross station, older sash windows in a rental need their mastic kept sound to keep the weather out.

It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.

How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Parking around Chobham is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Tell us about any water getting in
- Keep children and pets away from the work area
- 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. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

Windows and doors in Chobham
With historic houses such as Botleys Mansion (about 3.2 miles north-east) nearby, there’s older building stock in the area around Chobham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as St Lawrence CofE (Aided) Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Chobham
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Chobham, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
