What sand mastic looks like in Ide Hill
Historic houses like Chartwell (about 2.1 miles west) are a reminder that the area around Ide Hill 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. 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.
Homes close to Church of St Mary at South End of Village Green include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Sevenoaks station? Then any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Ide Hill Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How we handle sand mastic in Ide Hill
Across Ide Hill, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have draughty sash windows at the surround and weathered mastic on the most exposed windows, we can put it right, on tenement windows, stone surrounds and sash and case windows alike.
Mastic can only go onto a dry, clean joint, so window work in Ide Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with a 12-month guarantee.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Find out about consent before window work on a listed home
- Do not run silicone over sand mastic
- Get any rot dealt with first
- Plan mastic work ahead of painting
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Honest limits

What should I tell you?

What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can I paint the new mastic?

Do I have to be there?

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the job changes by surface

What else we do in Ide Hill
Leave it or put it right?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Ide Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.
