Quendon Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homeowners, landlords and businesses in Quendon. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
How we handle sand mastic in Quendon
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include draughts and rain around sash boxes and crumbling sand mastic round a window, across brick reveals, stone surrounds and tenement windows.
Somewhere as small as Quendon, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee.

What we are called out for in Quendon
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they normally need raking out.
Signs it’s time to call us include:
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Tired mastic found when preparing windows for paint
Rented homes near Newport (Essex) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- Are they insured?
- Whether VAT is included
- How long the guarantee is
- How the joint is cleaned and prepared

Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Masonry that needs repairing
- Whether work needs listed building consent
- Sashes that need overhauling
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Stone surrounds
- Brick reveals
- Sash and case windows
- Tenement windows
- Period & listed homes
- Timber door frames
Why it’s worth doing now in Quendon
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Quendon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- Experience in homes, commercial sites and hotels
- Trusted Arbo and Everbuild sealants
- Old sealant always removed completely

What sand mastic looks like in Quendon
Historic houses like Horham Hall (about 4.6 miles east) are a reminder that the area around Quendon 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 is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of Quendon, the joint between an old wall and a newer frame is normally the first place rain gets in.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
- Look over the window mastic once a year
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
