External & façade joints in Queensferry, Edinburgh
External mastic across Queensferry and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on
- Façade panels
- Render & cladding joints

External mastic in Queensferry, done properly
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for water getting into walls through failed joints and leaking joints around cladding and façade panels, across brickwork movement joints, copings & trims and render & cladding joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
You get a one-year guarantee, the same in Queensferry as everywhere else we work.

Your questions about external mastic in Queensferry
Is Queensferry within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect external mastic in Queensferry?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Edinburgh.
What we’re called out for in Queensferry
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
These are the problems we’re asked about most:
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
In the older streets around Queensferry Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Queensferry: local notes
Queensferry is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. For listed homes and conservation areas, check with the council before changing how windows or walls look.
If you let a flat or house near Dalmeny station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Queensferry High School? Then larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. Outside jobs in Queensferry 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 over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
Keeping the joints in good condition
Looking after new joints is easy:
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Do not let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
