Sand mastic for sash & case windows in Shalford, Surrey
Professional sand mastic in and around Shalford, with every bit of old sealant taken out first.
- Gaps round a timber door in stone or brick
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
Keeping the joints in good condition
So the new joints stay in good condition:
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

What sand mastic looks like in Shalford
Historic houses like Guildford Castle (about 1.5 miles north) are a reminder that the area around Shalford 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Shalford Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.

Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How it works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take a few hours for a single window, longer for several. Somewhere like Shalford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
