- Gaps between timber frames and stone or brick

- Mastic that needs renewing before redecorating
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sand mastic in Hunton, done properly
We work across Hunton renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have window mastic to renew ahead of painting and gaps between timber frames and stone or brick, we can help, on sash and case windows, timber door frames and brick reveals alike.
Homes in small places like Hunton 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.
Every job is covered by a one-year guarantee.

What we’re called out for in Hunton
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Surface by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Make sure water runs off the sill
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.

Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.

It skins over fairly quickly but takes longer to harden fully. We’ll explain what to expect before we leave.

What we do, step by step

For a village or hamlet like Hunton, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
