Sand mastic in Marley
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and modern sealant on a period surround, we can put it right, whatever the surface.
Around Marley, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

How to look after the new joints
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several. For a village or hamlet like Marley, 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.
- First, we look at the surrounds with you and agree what needs doing.
- 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 finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

When to call us in Marley
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The problems people usually mention when they call include:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Cracked mastic round a front door frame
For landlords with property near Snowdown station, any sash windows need sound mastic to keep draughts and rain out.
Before you book anyone
- How the colour is chosen
- Whether all the old sealant comes out first
- Whether they’re fully insured
- What preparation is included
Why deal with it now?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Marley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What you get with us
- We are fully insured
- We leave the area clean and tidy
- Old sealant always removed completely
- Over 20 years’ experience

Frames and glazing around Marley
Historic houses like Goodnestone Park (about 4.7 miles north-east) are a reminder that the area around Marley has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Giles, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Barham Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
