External mastic in Clermiston
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on copings & trims, brickwork movement joints and façade panels, and the jobs we see most are sealant that has lost its bond to the brick or render and panel joints letting water in.
Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. In Clermiston, access needs planning, and work on shared parts may need the other owners’ agreement.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What external mastic looks like in Clermiston
Clermiston 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near South Gyle station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Craigmount High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Caroline Park, about 2.7 miles north-east, is one of the historic houses in the wider area around Clermiston.

Why it’s worth doing now in Clermiston
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Private landlords in Clermiston must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Nearby places to Clermiston
Also in Clermiston
Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Clermiston questions
Is external mastic in a coastal place like Clermiston any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
How is work on the outside of a tenement in Clermiston generally arranged?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
How do you reach high-level joints?
It depends on the building. Send us photos and a rough idea of the height, and we will confirm what access is needed.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so the joint does not draw the eye.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Point out the joints to other trades
- Leave the joints unpainted unless we have said otherwise
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Landlord and commercial work in Clermiston
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
