How we handle sand mastic in Etchingham
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, sash and case windows and stone surrounds, and common reasons people get in touch are gaps between timber frames and stone or brick and tired mastic found when preparing windows for paint.
Homes in small places like Etchingham 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.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Leave it or put it right?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In a small place like Etchingham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why us?
- 12-month guarantee on every job
- Old sealant always removed completely

- Domestic, commercial and hotel work

Etchingham homes and the weather
Historic houses like Bateman's (about 2.8 miles south-west) are a reminder that the area around Etchingham 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. 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.
Managing a site like Etchingham Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Etchingham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

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.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid heavy scraping on the mastic joint
- Clear gutters so water doesn’t pour onto the windows
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes anything from a few hours to a full day, depending on how many windows. In a small place like Etchingham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in

Advice
Do you need sand mastic in Etchingham?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Look out for any of the following:
- Open joints round the window box
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
- Mastic dropping out of the joint
Homes close to The Parish Church of St Nicholas and St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Your questions about sand mastic in Etchingham
Is Etchingham within the area you cover?
Yes. Etchingham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Etchingham station?
Yes. We work for landlords and letting agents as well as householders. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How long will you be here?
Typically it takes anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we will say how long yours will take.
Do you guarantee sand mastic work?
Every job comes with our 12-month guarantee.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
