Sand mastic for sash & case windows in Camberley, Surrey
Problem with your window and door surrounds in Camberley? We cut out the old, prepare the joints and apply the right sealant.
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
About our sand mastic in Camberley
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have modern sealant on a period surround and gaps round a timber door in stone or brick, we can help, whatever the surface.
Plenty of homes in a town like Camberley have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Sills, frame heads and glazing joints are where leaks generally start.
All our work comes with a 12-month guarantee.

Frames and glazing around Camberley
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 Prior Heath Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Camberley station, any sash windows need sound mastic to keep draughts and rain out.

Your questions about sand mastic in Camberley
What guarantee comes with sand mastic in Camberley?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do sand mastic in Camberley?
Yes, Camberley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How long does sand mastic 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 will say how long yours will take.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
How the job changes by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

What we are called out for in Camberley
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
The most common problems we see are:
- Modern sealant on a period surround
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
For an older house near a landmark such as Church of St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- Whether all the old sealant comes out first
- What preparation is included
- Who does the work, and how experienced they are
- Are they insured?
What sealant work cannot fix
We won’t take on work that will not last, so these are the limits:
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
