External mastic for homes and businesses in Middleton
On houses, flats and commercial buildings across Middleton, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have cracked joints where brick meets render or frames and rigid filler in a joint that should flex, we can help, on joints between brick and frames, brickwork movement joints and render & cladding joints alike.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
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.

Why it’s worth doing now in Middleton
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish
- Fully insured
- Approved under the ARBOMaster scheme
What affects the quote in Middleton
Call for a quick quote. The main things that affect it are:
- The amount of work
- The product the joint needs
- The old material and how stubborn it is
- Access and height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Where the property is
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building. For a place like Middleton, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Mention any tricky access

Questions from Middleton
Can you help a landlord with a rental near Dunkeld & Birnam station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Can you do external mastic in Middleton?
Yes, Middleton is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Middleton buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Dunkeld & Birnam station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Old Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Don’t let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
