Bieldside External Mastic
Specialist external mastic for Bieldside: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
How to look after the new joints
A little care helps the new joints last. We recommend:
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
- Point out the joints to other trades
- Have failed joints looked at early
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
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, all bigger jobs than a reseal.
External mastic for homes and businesses in Bieldside
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. Typical jobs include weeds or debris growing in open joints and sealant pulling away from one side of the joint, across façade panels, concrete & block and brickwork movement joints.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Bieldside, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
There’s a 12-month guarantee on every job.

What else we do in Bieldside
External mastic in Bieldside: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and sealing against granite needs clean, sound edges and a sealant that suits stone.
For landlords with property near Aberdeen station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Cults Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Your questions about external mastic in Bieldside
Is Bieldside in your area for external mastic?
Yes. We work across all of Scotland, and Bieldside is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
How do repairs to the shared parts of a tenement in Bieldside get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Aberdeen.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Bieldside.
Do you need external mastic in Bieldside?
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
These are the problems we are asked about most:
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
If you live in an older home near Cults West Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How long the guarantee is
- Which colour the sealant will be
- Which sealant they’ll use, and why
- How much experience the applicator has
When it isn’t the sealant
We won’t take on work that won’t last, so these are the limits:
- Render that is blown, hollow or coming away
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
What we seal
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Copings & trims
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Scottish rain finds any gap around a frame or wall joint, and in Bieldside, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a city area like Bieldside, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
