FAQs for Berryden
How is work on the outside of a tenement in Berryden normally arranged?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Windows often belong to the individual flat, but it’s worth checking your deeds.
I let a flat near Aberdeen station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
External mastic in Berryden, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Common call-outs are for sealant that has lost its bond to the brick or render and joints with sealant missing in places, across brickwork movement joints, copings & trims and render & cladding joints.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Berryden, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
All our work comes with our one-year guarantee, wherever you are in Aberdeen.

Signs you need external mastic in Berryden
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
If you look after a building such as St Machar Academy, its movement joints, gutters and trims need looking after like any other building’s.

How we quote for external mastic
You’ll get a clear quote before any work starts. It takes into account:
- How many areas need sealing
- Access and height
- Any mould that needs treating
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The rough size of the job
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the building. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Berryden, tell us the floor, how the door entry system works and where we can park nearby.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
How to get a quote
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, drop us a line at info@mrmastic.co.uk.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure movement joints aren’t pointed over
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What we can’t put right
New sealant can’t fix everything, and we will tell you before work begins. It will not solve:
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Outside joints around Berryden
Berryden 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. 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.
Letting a property close to Aberdeen station? Then 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 0.9 miles south-east, show how far back building around Berryden goes.
