How we handle sand mastic in Bishop's Sutton
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for weathered mastic on the most exposed windows and old sand mastic that has cracked, crumbled or fallen out, across tenement windows, stone surrounds and timber door frames.
Somewhere as small as Bishop's Sutton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Advice
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When something else is needed
A few problems are outside what sealant work can do:
- Masonry that needs repairing
- Broken panes
- Decisions on consent for listed homes
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Why it’s worth doing now in Bishop's Sutton
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Bishop's Sutton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- More than 20 years in sealant work
- Any old sealant cut out fully, not covered over

Is consent needed for window work on a listed home?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
What we’re called out for in Bishop's Sutton
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
If you live in an older home near Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- What product goes in the joint
- How the colour is chosen
- When the joint can take water or movement
- What insurance they hold

Frames and glazing around Bishop's Sutton
With historic houses such as Hinton Ampner House (about 2.9 miles south) nearby, there’s older building stock in the area around Bishop's Sutton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Perins School, its window and door frames need their mastic kept sound, just like a home’s.
