Sand mastic for homes and businesses in Cressing
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you are dealing with a silicone bead on a sash window that spoils the look and gaps round a timber door in stone or brick, we can put it right.
Homes in small places like Cressing often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Cressing
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Parish Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Cressing station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Should I use sand mastic or silicone?
We will talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new sealant bonds properly.
Different surfaces, different methods
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Signs you need sand mastic in Cressing
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice something like this:
- Old cement repairs round a window that have failed
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
For site and facilities teams at buildings such as Cressing Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
