How we handle window mastic in Duddingston
From a single sill to a whole house of windows, you will get a clear quote before work begins. Just email us at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached for window mastic in Duddingston. We work on aluminium frames, window sills and patio & French doors, and people most often call us about old mastic that has gone black or come away and white mastic on grey or black frames.
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.
A one-year guarantee comes as standard.

How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Duddingston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Advice
What window mastic looks like in Duddingston
Duddingston is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Schools such as Holy Rood High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Duddingston Kirk, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Duddingston is about 1 mile south-west of South Portobello, in Edinburgh. If you need window mastic in Duddingston, it’s easy to get a quote: please send an email to info@mrmastic.co.uk.

When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- A frame that has rotted at the joint
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.

Signs you need window mastic in Duddingston
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
Most people get in touch after spotting one of these:
- Gaps left after new windows were fitted
- Mastic that’s falling out in pieces
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
If you let a flat or house near Brunstane station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why it’s worth doing now in Duddingston
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before we start.

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
