Sand mastic for homes and businesses in Easington
We work across Easington renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on brick reveals, stone surrounds and sash and case windows, and people most often call us about draughts and rain around sash boxes and patchy fillers round a sash window.
Homes in small places like Easington 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.
You get a 12-month guarantee, the same in Easington as everywhere else we work.

How the job changes by surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
The process
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours per window, depending on the condition of the joints. In a small place like Easington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit

What we’re called out for in Easington
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Keep an eye out for any of the following:
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
- Window mastic to renew ahead of painting
Schools such as Long Crendon School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Looking after it afterwards
To keep the joints looking good and working properly:
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
Common questions in Easington
I let a flat near Haddenham & Thame Parkway station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Easington?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What sand mastic looks like in Easington
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 Boarstall Tower (about 4.6 miles north-west) are a reminder that the area around Easington 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’s traditional sand mastic.
If you live in an older home near Parish Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Haddenham & Thame Parkway station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
