Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Around Timsbury, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits. We’ll send you a clear quote for the lot.

How we handle sand mastic in Timsbury
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, across timber door frames, sash and case windows and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Timsbury is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Timsbury as everywhere else we work.

What else we do in Timsbury
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Ask us before painting near the mastic
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Timsbury questions
Do you work for landlords with property near Mottisfont & Dunbridge station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Timsbury?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Sand mastic in Timsbury: local notes
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. With historic houses such as Mottisfont Abbey (about 1.6 miles north-west) nearby, there’s older building stock in the area around Timsbury 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’s traditional sand mastic.
If you live in an older home near Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Mottisfont & Dunbridge station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Stanbridge Earls School, the mastic around its windows and doors needs looking after like any other building’s.
