How we handle sand mastic in Emerson Park
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We’re often asked to deal with modern sealant on a period surround and window mastic to renew ahead of painting, on brick reveals, sash and case windows and stone surrounds.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. In Emerson Park, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Windows and doors in Emerson Park
Historic houses like Hare Hall (about 1.2 miles north-west) are a reminder that the area around Emerson Park has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
In the older streets around All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Emerson Park station, any sash windows need sound mastic to keep draughts and rain out.

Is parking a problem for a job in Emerson Park?
Parking in Emerson Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Is the work guaranteed?
Our 12-month guarantee applies on every job.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will talk you through it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Look over the window mastic once a year
- Clear gutters so water does not pour onto the windows
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again.

What we are called out for in Emerson Park
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Most people get in touch after spotting one of these:
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
- Open joints round the window box
- Failed mastic on an exposed elevation
For site and facilities teams at buildings such as Nelmes Primary School, the mastic around its windows and doors needs looking after like any other building’s.
