Cummings Park buildings and the weather
Cummings Park 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Your title deeds say which parts are shared.
If you let a flat or house near Aberdeen station, outside joints that have cracked can let damp into a rental, so check them between lets. Historic houses such as Provost Skene's House, about 2.1 miles south-east, show how far back building around Cummings Park goes, and older homes nearby need a sealant that suits their walls.

External mastic in Cummings Park, done properly
For buildings in Cummings Park, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Common call-outs are for joints where the bead has come unstuck and weathered mastic that no longer stretches, across render & cladding joints, copings & trims and concrete & block.
Gutters and downpipes on tall city tenements are a long way up, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Cummings Park, access needs planning, and work on shared parts may need the other owners’ agreement.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Cummings Park, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Mention any tricky access

FAQs for Cummings Park
Does living near the coast affect external mastic in Cummings Park?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
I let a flat near Aberdeen station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How much does external mastic cost in Cummings Park?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

What affects the cost of external mastic
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- Whether there’s mould to deal with
- How much there is to do
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
To make quoting easier, please include:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We will give you a clear price before any work starts.
What we cannot put right
We won’t take on work that will not last, so these are the limits:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we’re called out for in Cummings Park
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
Managing a site like Northfield Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
