How we handle sand mastic in Five Oaks
We work across Five Oaks renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. Typical jobs include tired mastic found when preparing windows for paint and gaps where the frame meets the masonry, on tenement windows, sash and case windows and period & listed homes.
In a village or hamlet like Five Oaks, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What sand mastic looks like in Five Oaks
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.
Schools such as The Weald School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Different surfaces, different methods

Windows above ground floor need the right access. Tell us the height and we’ll confirm what’s needed.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Do you need sand mastic in Five Oaks?
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Somewhere like Five Oaks needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
