Questions from Ardler
How do repairs to the shared parts of a tenement in Ardler get organised?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is external mastic in a coastal place like Ardler any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
How we handle external mastic in Ardler
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. Common call-outs are for leaking joints around cladding and façade panels and movement joints filled with mortar instead of sealant, on copings & trims, concrete & block and façade panels.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Ardler, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
All our work comes with a 12-month guarantee, wherever you are in Dundee.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Parking in city streets around Ardler 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Damp that is not coming from the joint
- Movement that is more than a sealant joint can take
- Failed render or damaged cladding panels
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Wind-driven rain gets into any failed joint on the outside of a city building, and in Ardler, damp can spread through stone and plaster before anyone sees it.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Common problems we fix in Ardler
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
People usually contact us after spotting one of these:
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Joints where the bead has come unstuck
- Joints with sealant missing in places
For site and facilities teams at buildings such as Lawside Academy, its movement joints, gutters and trims need looking after like any other building’s.

What external mastic looks like in Ardler
Ardler is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Camperdown House, about 1.1 miles west, is one of the historic houses in the wider area around Ardler. For landlords with property near Invergowrie station, outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
Aftercare is simple:
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Act on the first splits you see
- Leave the joints unpainted unless we’ve said otherwise
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
