Sand mastic for homes and businesses in Eridge Green
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on stone surrounds, timber door frames and period & listed homes, and the jobs we see most are draughty sash windows at the surround and mastic that needs renewing before redecorating.
Mastic can only go onto a dry, clean joint, so window work in Eridge Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in Eridge Green and everywhere else we cover.

Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Eridge Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.

How the job changes by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Landlord and commercial work in Eridge Green
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

I let a flat near Eridge station. Can you help?

Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll advise.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What affects the quote in Eridge Green
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
How to look after the new joints
After the cure time, these simple habits help:
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Sand mastic in Eridge Green: local notes
With historic houses such as Groombridge Place (about 1.9 miles north-west) nearby, there’s older building stock in the area around Eridge Green 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. 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.
In the older streets around Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Eridge station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

We bring what the job needs, so it can be finished in one trip where possible.
