Sand mastic in West Hyde
Silicone on a period window often looks wrong and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include draughty sash windows at the surround and gaps round a timber door in stone or brick, across brick reveals, stone surrounds and sash and case windows.
Somewhere as small as West Hyde, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How we quote for sand mastic

- How much old sealant there is and how hard it is to remove
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the job changes by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. For a village or hamlet like West Hyde, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us if parking is tricky
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Questions from West Hyde

What should I tell you?

Can I choose the sealant colour?

Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Sand mastic in West Hyde: local notes
Historic houses like Chenies Manor House (about 4.4 miles north) are a reminder that the area around West Hyde has older buildings as well as new. In older buildings, 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.
Rented homes near Denham Golf Club station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Maple Cross Junior Mixed Infant and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Thomas of Canterbury, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in West Hyde
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like West Hyde, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
