About our sand mastic in Kit's Coty
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on timber door frames, sash and case windows and stone surrounds, and the jobs we see most are open joints round the window box and mastic that needs renewing before redecorating.
Homes in small places like Kit's Coty often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same 12-month guarantee.

Landlords, agents and businesses in Kit's Coty
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
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.
Looking after it afterwards
Aftercare is simple:
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What happens if it’s left?
New sash windows are a major, costly change 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. Where a wall is exposed, as many are in small places like Kit's Coty, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Frames and glazing around Kit's Coty
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. Historic houses like Starkey Castle (about 3.4 miles north-west) are a reminder that the area around Kit's Coty 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 is traditional sand mastic.
Rented homes near Aylesford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near St Alban's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Tunbury Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
