FAQs for Crimond
Is external mastic in a coastal place like Crimond any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Is Crimond in your area for external mastic?
Yes, Crimond is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Aberdeenshire.
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 hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How do I get a quote for external mastic in Crimond?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
How we handle external mastic in Crimond
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with sealant that has lost its bond to the brick or render and water getting into walls through failed joints, we can put it right, whatever the surface.
In and around a place like Crimond, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
All our work is covered by our 12-month guarantee, wherever you are in Aberdeenshire.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Make sure movement joints are not pointed over
- Point out the joints to other trades
- Check external joints each spring
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Other services in Crimond
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In a place like Crimond, 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, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

What external mastic looks like in Crimond
Crimond is within about 3 miles 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. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Around Crimond, as everywhere, external mastic is only as good as the preparation behind it.

Do you need external mastic in Crimond?
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Failed seals between different materials
- Panel joints letting water in
For an older house near a landmark such as Crimond Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Somewhere like Crimond may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us about any water getting in
- Mention any tricky access
- Let us know about earlier repairs to the joints

- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Where the property is
