Sand mastic in Brentwood, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and mastic worn away on windows facing the weather, we can help.
In a town like Brentwood, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
Your job is guaranteed for a year, as with all our work.
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a few hours for a single window, longer for several. In Brentwood, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- 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
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

Advice
What the job involves on each surface
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.

Why act early in Brentwood
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Brentwood, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Do you need sand mastic in Brentwood?
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber and we normally remove them.
People normally contact us when they notice something like this:
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
If you let a flat or house near Brentwood station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sand mastic in Brentwood: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ingatestone Hall (about 4.4 miles north-east) are a reminder that the area around Brentwood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Becket Keys Church of England School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Thomas of Canterbury, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
