- Open joints round the window box
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
Aftercare tips
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Sand mastic in Moulsecoomb, done properly
Across Moulsecoomb, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have draughts and rain around sash boxes and modern sealant on a period surround, we can help.
Houses in smaller places like Moulsecoomb can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows. A visit to Moulsecoomb is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- On commercial sites, let us know about site rules

Advice
What sand mastic looks like in Moulsecoomb
Moulsecoomb is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Preston Manor & Gardens (about 1.8 miles west) nearby, there’s older building stock in the area around Moulsecoomb 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.
Managing a site like Moulsecoomb Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Moulsecoomb station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St. Andrew's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Moulsecoomb: your questions answered
Do you work for landlords with property near Moulsecoomb station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Moulsecoomb within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
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 advise.
Where are you based?
We work from Crawley. Our applicators cover Moulsecoomb.
How long will you be here?
A typical job takes anything from a few hours to a full day, depending on how many windows. We will confirm how long when we quote.
Do you guarantee sand mastic work?
All our work has a one-year guarantee, and we are fully insured.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Moulsecoomb, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear quote for the lot.
