What the job involves on each surface

Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Sand mastic in Walton Manor
We work across Walton Manor renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on sash and case windows, brick reveals and tenement windows, and the jobs we see most are window mastic to renew ahead of painting and gaps between timber frames and stone or brick.
Many houses in smaller places like Walton Manor have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Advice
Walton Manor questions
I let a flat near Oxford station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Walton Manor in your area for sand mastic?
Yes. We work across London and the South East, and Walton Manor is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.
How much does sand mastic cost in Walton Manor?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.

Other services in Walton Manor
Do you need sand mastic in Walton Manor?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
The most common problems we see are:
- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
Historic houses such as Holywell Manor, about 1 mile south-east, show how far back building around Walton Manor goes, and older homes nearby need a sealant that suits their walls.
Before booking anyone
- Whether all the old sealant comes out first
- Whether VAT is included
- How hidden problems are handled
- How long to leave it before use
When it isn’t the sealant
It helps to know what we cannot do:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
What we seal
- Timber door frames
- Stone surrounds
- Sash and case windows
- Tenement windows
- Brick reveals
- Period & listed homes
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Don’t run silicone over sand mastic
- Take care around the mastic when scraping paint
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Walton Manor homes and the weather
Historic houses like Holywell Manor (about 1 mile south-east) are a reminder that the area around Walton Manor 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. 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.
For landlords with property near Oxford station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as St Aloysius' Catholic Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
