Sand mastic in Kingston Blount, done properly
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are open joints round the window box and mastic round period door frames that has failed.
Mastic can only go onto a dry, clean joint, so window work in Kingston Blount is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

Signs you need sand mastic in Kingston Blount
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
The problems people normally mention when they call include:
- Weathered mastic on the most exposed windows
- A silicone bead on a sash window that spoils the look
- Draughty sash windows at the surround
- Patchy fillers round a sash window
For an older house near a landmark such as Church of the Nativity of the Blessed Virgin Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent
- Cracked or broken glass
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.
What we seal
- Tenement windows
- Period & listed homes

What the job involves on each surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Kingston Blount, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Kingston Blount, 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 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 isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
