Landlord and commercial work in Shandon

How we handle external mastic in Shandon
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on façade panels, brickwork movement joints and render & cladding joints, and people most often call us about movement joints with cracked, split or missing sealant and sealant pulling away from one side of the joint.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. In Shandon, access needs planning, and work on shared parts may need the other owners’ agreement.
There’s a 12-month guarantee on every job, large or small.

Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a tenement flat in Shandon, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
FAQs for Shandon
Is external mastic in a coastal place like Shandon any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How is work on the outside of a tenement in Shandon normally arranged?
It generally 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.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
How much does external mastic cost in Shandon?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

When to call us in Shandon
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Most people get in touch after spotting something like this:
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
- Water getting into walls through failed joints

- Is VAT in the price?

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Parking in city streets around Shandon can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Advice
What external mastic looks like in Shandon
Shandon is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look.
Historic houses such as Whitefoord House, about 2.5 miles north-east, show how far back building around Shandon goes, and older homes nearby need a sealant that suits their walls. Managing a site like Craiglockhart Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
