In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Sand mastic in Farley Green
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, timber door frames and period & listed homes, and the jobs we see most are mastic that needs renewing before redecorating and gaps between timber frames and stone or brick.
Around Farley Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, large or small.

How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It generally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Farley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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 isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Frames and glazing around Farley Green
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Chilworth Manor (about 2.7 miles north-west) are a reminder that the area around Farley Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Chilworth station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Farley Green: your questions answered
Can you help a landlord with a rental near Chilworth station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Farley Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
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 work on a listed home or in a conservation area.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Signs you need sand mastic in Farley Green
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Look out for these signs:
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Cement or filler used on old window joints that has cracked
In the older streets around St Michael, the joint between an old wall and a newer frame is usually the first place rain gets in.
