Ringmer Sand Mastic
Sand mastic across Ringmer and nearby, with old sealant always removed completely and a 12-month guarantee.
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. In an older home around Ringmer, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why Ringmer customers choose us
- Any old sealant cut out fully, not covered over

Sand mastic for homes and businesses in Ringmer
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have failed mastic on an exposed elevation and crumbling sand mastic round a window, we can put it right, on period & listed homes, tenement windows and sash and case windows alike.
Houses in smaller places like Ringmer can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
Every job is covered by our 12-month guarantee, wherever you are in East Sussex.

Frames and glazing around Ringmer
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Glyndebourne (about 1.1 miles south) nearby, there’s older building stock in the area around Ringmer as well as newer homes. 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.
If you let a flat or house near Glynde station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Ringmer Primary and Nursery School? Then its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
After the cure time, these simple habits help:
- Look over the window mastic once a year
- Keep sills and gutters clear so water drains away
- Don’t run silicone over sand mastic
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.

Is Ringmer in your area for sand mastic?

What does sand mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Do you need sand mastic in Ringmer?
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Look out for any of the following:
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Open joints round the window box
In the older streets around The Parish Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. A visit to Ringmer is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need doing.
- 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 tricky access
- Tell us about any water getting in
- Mention any parking rules near the property
