About our external mastic in Peterhead
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with weeds or debris growing in open joints and leaking joints around cladding and façade panels, we can put it right, on façade panels, joints between brick and frames and concrete & block alike.
Harled walls are common in Scottish towns like Peterhead, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Gutters and fascias here take plenty of Scottish weather too.
We stand behind the work with a 12-month guarantee.

When something else is needed
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Structural movement, which needs a surveyor or engineer
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

What external mastic looks like in Peterhead
Peterhead is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Peterhead, as everywhere, external mastic is only as good as the preparation behind it.

Why act early in Peterhead
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In Peterhead, wind and rain soon get through failed outside joints. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
A few things move the cost up or down: 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 affects the quote in Peterhead
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- Any mould that needs treating
- How easy the joints are to reach
- The number of rooms or windows
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- The rough size of the job
- The type of property
- Pictures of the joints, sent by email
For a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In a Scottish town like Peterhead, parking is generally straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Peterhead: your questions answered
Can you do external mastic in Peterhead?
Yes. Our work covers the whole of Scotland, and Peterhead is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
What guarantee comes with external mastic in Peterhead?
All our work, in Peterhead and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
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.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How do I get a quote for external mastic in Peterhead?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you have insurance?
Yes. Full insurance covers our work.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
