How we handle sand mastic in Cross in Hand
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. Common call-outs are for cracked mastic round a front door frame and open joints round the window box, across tenement windows, brick reveals and stone surrounds.
Somewhere as small as Cross in Hand, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

Questions from Cross in Hand
Is Cross in Hand within the area you cover?

Do you work for landlords with property near Buxted station?

Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere as small as Cross in Hand, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on

You do not need to know the technical terms. It helps if you can tell us:
- Where the property is

Cross in Hand homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Buxted station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Cross-in-Hand Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Keeping the joints in good condition
So the new joints stay in good condition:
- Look over the window mastic once a year
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, 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.
