Chestfield Sand Mastic
We cover Chestfield for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.

Sand mastic in Chestfield, done properly
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on period & listed homes, stone surrounds and brick reveals, and people most often call us about mastic worn away on windows facing the weather and draughty sash windows at the surround.
Around Chestfield, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Chestfield and everywhere else we cover.

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Crumbling stone or brickwork round the window
- Broken panes
- Sashes that need overhauling
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Frames and glazing around Chestfield
Chestfield is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Chestfield & Swalecliffe station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Swalecliffe Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Questions from Chestfield
Does living near the coast affect sand mastic in Chestfield?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you work for landlords with property near Chestfield & Swalecliffe station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we’ll talk you through it.
How we quote for sand mastic
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- How many areas need sealing
- The type of sealant required
- The size of the job
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Photos by email, if that is easy
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or send us an email.
Surface by surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Why it’s worth doing now in Chestfield
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Chestfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

- 12-month guarantee on every job

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Chestfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

When to call us in Chestfield
Timber frames move with the seasons. The movement cracks the mastic little by little.
Look out for these signs:
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
- Patchy fillers round a sash window
- Mastic that needs renewing before redecorating
For an older house near a landmark such as Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
