How we handle sand mastic in Esher
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Common call-outs are for modern sealant on a period surround and gaps round a timber door in stone or brick, on period & listed homes, tenement windows and timber door frames.
Homes around Esher range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Whatever the size of the job, you get the same one-year guarantee in Esher and across Surrey.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
- Get any rot dealt with first
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Frames and glazing around Esher
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. Historic houses like The Homewood (about 1.8 miles south-west) are a reminder that the area around Esher has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Milbourne Lodge School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Esher station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

What affects the quote in Esher
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Which sealant suits the joint
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

You don’t need to know the technical terms. It helps if you can tell us:

- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.

Esher questions
Can you do sand mastic in Esher?
Yes, Esher is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Esher station. Can you help?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll talk you through it.
What information do you need?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
What we are called out for in Esher
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they usually need raking out.
These are the problems we’re asked about most:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Draughty sash windows at the surround
- Failed mastic on an exposed elevation
For an older house near a landmark such as St George's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- What preparation is included
- What the cure time is
- Whether all the old sealant comes out first
- What guarantee comes with the work
Different surfaces, different methods
Stone surrounds
The stone is treated with care when the old mastic comes out.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
