Sand mastic in Weeley Heath
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on brick reveals, tenement windows and stone surrounds, and the jobs we see most are tired mastic found when preparing windows for paint and patchy fillers round a sash window.
Homes in small places like Weeley Heath 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.
All of our work is guaranteed for twelve months.

Should I try it myself first?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Go gently near the mastic when preparing windows
- Clear gutters so water doesn’t pour onto the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. In a small place like Weeley Heath, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Questions from Weeley Heath
Is Weeley Heath in your area for sand mastic?
Yes, Weeley Heath is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Weeley Heath?
Yes, Weeley Heath is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We will confirm how long when we quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Weeley Heath homes and the weather
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. Historic houses like Thorpe Hall (about 2.1 miles east) are a reminder that the area around Weeley Heath has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Weeley St Andrew's CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Weeley Heath
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Weeley Heath, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
