Common questions in Mosspark
Who arranges sealant work on the shared parts of a tenement in Mosspark?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Do you work for landlords with property near Corkerhill station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll say how long yours will take.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
About our external mastic in Mosspark
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Common call-outs are for leaking joints around cladding and façade panels and water getting into walls through failed joints, across copings & trims, joints between brick and frames and façade panels.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Mosspark, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
Every job is covered by a one-year guarantee.

How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Mould in or behind the old joints
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
What to tell us for a quote
To make quoting easier, let us know:
- The type of property
- A few photos by email, if you can
- Whether it has been sealed before
- What’s wrong with the joints now

What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Tell us what the building has when you get in touch.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
For anyone letting property in or around Mosspark, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Do you need external mastic in Mosspark?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Signs it’s time to call us include:
- Panel joints letting water in
- Weeds or debris growing in open joints
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
For site and facilities teams at buildings such as Craigton Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
The process
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Mosspark, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules

Related advice
Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Scottish rain finds any gap around a frame or wall joint, and in Mosspark, damp can spread through stone and plaster before anyone sees it.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Mosspark buildings and the weather
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
