How we handle sand mastic in Hill Brow
We work across Hill Brow renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on timber door frames, brick reveals and tenement windows, and people most often call us about mastic that needs renewing before redecorating and mastic worn away on windows facing the weather.
Around Hill Brow, 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.
There’s a 12-month guarantee on every job, whatever its size.

Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
What we are called out for in Hill Brow
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
Most people get in touch when they notice something like this:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
Homes close to Rake Mission Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Hill Brow, 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.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
