Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How we handle sand mastic in Lower Beeding
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for old sand mastic that has cracked, crumbled or fallen out and open joints round the window box, across sash and case windows, tenement windows and brick reveals.
Somewhere as small as Lower Beeding, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

Lower Beeding homes and the weather
Historic houses like Tyes Place (about 4.1 miles east) are a reminder that the area around Lower Beeding 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Holy Trinity CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to The Parish Church of the Holy Trinity include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Horsham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Clear gutters so water doesn’t pour onto the windows
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Planning or listed building consent (your local planning authority decides)
- Decayed frames that need repair
- Broken panes
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Is sand mastic better than silicone for my windows?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
How long does the job take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll say how long yours will take.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.

A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Where are you based?

Can you replace silicone on a period window with sand mastic?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
