Why it’s worth doing now in Redford
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Around Redford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Sand mastic for homes and businesses in Redford
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 timber door frames, tenement windows and period & listed homes, and common reasons people get in touch are mastic that needs renewing before redecorating and patchy fillers round a sash window.
In a village or hamlet like Redford, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Redford and everywhere else we cover.

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
What sand mastic looks like in Redford
With historic houses such as Cowdray House (about 3.4 miles south-east) nearby, there’s older building stock in the area around Redford as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Luke, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Liphook station, any sash windows need sound mastic to keep draughts and rain out.

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Sort the mastic before the decorators arrive
- Leave the new mastic unpainted
- Avoid patching sand mastic with silicone
- Make sure water runs off the sill
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
How the job changes by surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Your questions about sand mastic in Redford
Is Redford in your area for sand mastic?
Yes, Redford is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Can you help a landlord with a rental near Liphook station?

Yes. We are fully insured.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
