Sand mastic in Newpound Common
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you’re redecorating. We work on timber door frames, brick reveals and sash and case windows, and common reasons people get in touch are mastic dropping out of the joint and failed mastic on an exposed elevation.
Homes in small places like Newpound Common often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months, in Newpound Common and everywhere else we cover.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Do you need sand mastic in Newpound Common?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The problems people usually mention when they call include:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
If you live in an older home near The Parish Church of St Peter Ad Vincula, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Newpound Common homes and the weather
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.
Rented homes near Billingshurst station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Wisborough Green Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Newpound Common
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. In a small place like Newpound Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How the visit works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a single window, longer for several. In a small place like Newpound Common, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Advice
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Clear gutters so water doesn’t pour onto the windows
- Get any rot dealt with first
- Do not run silicone over sand mastic
- Inspect the joints round the windows every year or so
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
