FAQs for Portessie
Does living near the coast affect external mastic in Portessie?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Portessie in your area for external mastic?
Yes, Portessie is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including the preparation. Your quote will say how long we expect yours to take.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
External mastic in Portessie, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. We work on façade panels, render & cladding joints and copings & trims, and common reasons people get in touch are hard, crazed mastic that has stopped moving and movement joints filled with mortar instead of sealant.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Portessie buildings and the weather
Portessie is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
In the older streets around St Peter's Church and Old Burial-Ground, an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens on the day

Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Portessie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.

Advice
What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Quotes for external mastic in Portessie
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- The old material and how stubborn it is
- The product the joint needs
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. 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.
What we need to know
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- What’s wrong with the joints now
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Act on the first splits you see
- Never let anyone fill a movement joint with mortar
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
When to call us in Portessie
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Panel joints letting water in
Managing a site like Buckie High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
