Queen's Cross questions
Can you help a landlord with a rental near Aberdeen station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Queen's Cross?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
External mastic for homes and businesses in Queen's Cross
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on brickwork movement joints, joints between brick and frames and concrete & block, and common reasons people get in touch are movement joints filled with mortar instead of sealant and hard, crazed mastic that has stopped moving.
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 Queen's Cross, access needs planning, and work on shared parts may need the other owners’ agreement.
Your job is guaranteed for a year, as with all our work.

When something else is needed
It helps to know what we can’t do too:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint

External mastic in Queen's Cross: local notes
Queen's Cross is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around Queen's Cross Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as Albyn School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

When to call us in Queen's Cross
Joints sealed without backing rod, or far too deep, rarely last. 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:
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
- Panel joints letting water in
- Failed seals between different materials
Letting a property close to Aberdeen station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
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 do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we do, step by step
At the end, we look at the finished work together. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on the size of the job. For a tenement in Queen's Cross, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

What else we do in Queen's Cross
Surface by surface
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The type of sealant required
- Whether the work is at height
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
To make quoting easier, let us know:
- The type of property
- Whether it has been sealed before
- Pictures of the joints, sent by email
- How we’d reach the joints
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, send an email to info@mrmastic.co.uk.
