Sand mastic for homes and businesses in Roxburgh
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on tenement windows, period & listed homes and brick reveals, and common reasons people get in touch are draughty sash windows at the surround and mastic dropping out of the joint.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Leave it or put it right?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Around Roxburgh, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why book with us
- An ARBOMaster approved applicator
- 20+ years of sealant experience
- Fully insured
- Sanitary silicone with an anti-fungal additive in wet areas

Sand mastic in Roxburgh: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For an older house near a landmark such as Roxburgh Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. In and around Roxburgh, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows.

- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.

Aftercare tips
So the new joints stay in good condition:
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Get any rot dealt with first
- Do not paint over the new mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
