External & façade joints in Comrie, Perth and Kinross
Professional external mastic in and around Comrie, with every bit of old sealant taken out first.
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
How we handle external mastic in Comrie
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have panel joints letting water in and weeds or debris growing in open joints, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Comrie depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Every job comes with our 12-month guarantee, wherever you are in Perth and Kinross.

Comrie questions
Is Comrie in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Comrie is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Is external mastic in Comrie guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
How do I get a quote for external mastic in Comrie?
Size, access and the old material all affect the cost. Call for a quick quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Related advice
Signs you need external mastic in Comrie
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Common reasons people contact us are:
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Damp patches traced to an open external joint
In and around Comrie, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What affects the quote in Comrie
We do not publish a price list. The quote depends on:
- Which sealant suits the joint
- Access and height
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The type of property
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Where the property is
If you are in Comrie and need external mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Why it’s worth doing now in Comrie
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a place like Comrie, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
What external mastic looks like in Comrie
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around Secession Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Landlord and commercial work in Comrie
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
