Leave it or put it right?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Bledlow Ridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Sand mastic for homes and businesses in Bledlow Ridge
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for gaps where the frame meets the masonry and weathered mastic on the most exposed windows, across tenement windows, sash and case windows and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Bledlow Ridge is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with a one-year guarantee, wherever you are in Buckinghamshire.

What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Timber door frames
Round a period front door, sand mastic gives the right look.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Bledlow Ridge homes and the weather
Historic houses like West Wycombe Park House (about 2.9 miles south-east) are a reminder that the area around Bledlow Ridge has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Bledlow Ridge School, its window and door frames need their mastic kept sound, just like a home’s.

No. We work neatly, protect the area around the joints and tidy up afterwards.

Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What should I tell you?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Aftercare tips
To keep the joints looking good and working properly:
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
What we’re called out for in Bledlow Ridge
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
Signs it’s time to call us include:
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Patchy fillers round a sash window
For landlords with property near Saunderton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
