What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Sand mastic in Hurst Wickham
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on timber door frames, brick reveals and stone surrounds, and common reasons people get in touch are window mastic to renew ahead of painting and mastic worn away on windows facing the weather.
Mastic can only go onto a dry, clean joint, so window work in Hurst Wickham is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How it works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Hurst Wickham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Advice
Hurst Wickham: your questions answered
Do you cover Hurst Wickham for sand mastic?
Yes. Our work covers London and the South East, and Hurst Wickham is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.

What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Is it possible to take out silicone and use sand mastic instead?
Usually, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
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 the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Common problems we fix in Hurst Wickham
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Common reasons people contact us are:
- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
For an older house near a landmark such as Church of St George, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Hurst Wickham homes and the weather
With historic houses such as Ockenden Manor (about 5 miles north) nearby, there’s older building stock in the area around Hurst Wickham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hassocks station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as St Lawrence CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
