About our sand mastic in Dulnain Bridge
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on timber door frames, stone surrounds and period & listed homes, and the jobs we see most are mastic worn away on windows facing the weather and draughty sash windows at the surround.
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.
Big or small, you get the same one-year guarantee.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. Outside jobs in Dulnain Bridge need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

We’ll always be straight with you, so here’s what new sealant won’t do:
- Damaged stone surrounds

- Broken panes

Common problems we fix in Dulnain Bridge
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.
Signs it’s time to call us include:
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
Around Dulnain Bridge, as everywhere, sand mastic is only as good as the preparation behind it.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What happens if it’s left?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
What you get with us
- Over 20 years’ experience
