Blake End Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Blake End and across Essex. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
How we handle sand mastic in Blake End
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, timber door frames and brick reveals, and the jobs we see most are window mastic to renew ahead of painting and open joints round the window box.
Somewhere as small as Blake End, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Timber door frames
Round a period front door, sand mastic gives the right look.
What we’re called out for in Blake End
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that needs renewing before redecorating
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
If you let a flat or house near Braintree station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before we start. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Blake End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid patching sand mastic with silicone
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
