How we handle sand mastic in Brighthampton
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you are dealing with open joints round the window box and mastic that needs renewing before redecorating, we can put it right.
Somewhere as small as Brighthampton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Leave the new mastic unpainted
- Do not run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Clear gutters so water doesn’t pour onto the windows
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Why it’s worth doing now in Brighthampton
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Brighthampton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
What sand mastic looks like in Brighthampton
Historic houses like Longworth House (about 2.5 miles south) are a reminder that the area around Brighthampton has older buildings as well as new. 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. 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 Mulberry Bush School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Giles' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about sand mastic in Brighthampton
Will you come out to Brighthampton?
Yes. Brighthampton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in Brighthampton?
Yes, Brighthampton is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Do you offer different sealant colours?
We’ll 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.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Where do you work from?
We work from Crawley. Our applicators cover Brighthampton, along with the rest of our area.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The process
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints for a typical job. Somewhere like Brighthampton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
