What’s sand mastic made of?

Can I paint the new mastic?

How long does sand mastic take?
A typical job takes anything from a few hours to a full day, depending on how many windows. We’ll confirm how long when we quote.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
How we handle sand mastic in Monk Sherborne
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. Common call-outs are for wind and rain getting in round a sash window and mastic round period door frames that has failed, across stone surrounds, brick reveals and period & listed homes.
Around Monk Sherborne, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, it’s backed by our 12-month guarantee in Monk Sherborne and across Hampshire.

- The problem you’ve noticed
- The address or postcode of the job
- Any access issues, like height or stairs
- If someone has resealed it before

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Monk Sherborne, the journey is planned in advance: 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.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Related advice
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Why it’s worth doing now in Monk Sherborne
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Monk Sherborne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Frames and glazing around Monk Sherborne
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like The Vyne (about 1.7 miles east) are a reminder that the area around Monk Sherborne 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.
Managing a site like The Priory Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Basingstoke station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
