Sand mastic in Pitch Green, done properly
Across Pitch Green, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on sash and case windows, period & listed homes and stone surrounds, and the jobs we see most are gaps between timber frames and stone or brick and weathered mastic on the most exposed windows.
Mastic can only go onto a dry, clean joint, so window work in Pitch Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee in Pitch Green and across Buckinghamshire.

When to call us in Pitch Green
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
These are the problems we’re asked about most:
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
If you live in an older home near Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- Whether they seal over old material or remove it
- Whether VAT is included
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Keep sills and gutters clear so water drains away
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Why it’s worth doing now in Pitch Green
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Pitch Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

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 call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
