About our sand mastic in Hatford
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on tenement windows, period & listed homes and timber door frames, and people most often call us about tired mastic found when preparing windows for paint and gaps round a timber door in stone or brick.
Outdoor sealant needs dry, clean surfaces, so work on frames around Hatford is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months.

When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Decayed frames that need repair
- Masonry that needs repairing
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Period & listed homes
- Timber door frames
- Sash and case windows
- Brick reveals
- Tenement windows
- Stone surrounds
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Around Hatford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Sort the mastic before the decorators arrive
- Ask us before painting near the mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Hatford: local notes
Historic houses like Longworth House (about 3.9 miles north-east) are a reminder that the area around Hatford has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Stanford in the Vale Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Holy Trinity Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
