Plantation External Mastic
External mastic across Plantation and nearby, with old sealant always removed completely.
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
External mastic in Plantation
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you are dealing with hard, crazed mastic that has stopped moving and joints pointed up with cement by mistake, we can help.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Plantation, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Every job is covered by our one-year guarantee.

Common questions in Plantation
Do you cover Plantation for external mastic?
Yes. We work across all of Scotland, and Plantation is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Plantation?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Outside joints around Plantation
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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Tenement House, about 1.1 miles north-east, is one of the historic houses in the wider area around Plantation, and older homes nearby need a sealant that suits their walls. Schools such as Lorne Street Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Exhibition Centre station? Then split movement joints are easy to miss on a rental until damp shows inside.
Plantation is about 1 mile west of Glasgow, in Glasgow. Plantation gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our Glasgow coverage runs to 183 places, Plantation among them.

What we do, step by step
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 work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In a city area like Plantation, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- 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.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

Advice
How we quote for external mastic
We don’t publish a price list. The quote depends on:
- The size of the job
- The product the joint needs
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.
Helping us quote
When you call or email, these details help:
- Roughly how big the job is
- Where the job is, and your postcode
- The problem you’ve noticed
- If someone has resealed it before
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Honest limits
We’ll always be straight with you, so here’s what sealant can’t fix:
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Joints between brick and frames
- Concrete & block

Why it’s worth doing now in Plantation
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Plantation, damp can travel a long way before it shows.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
