Do you need external mastic in Wasbister?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Look out for any of the following:
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
Around Wasbister, as everywhere, external mastic is only as good as the preparation behind it.

External mastic in Wasbister, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you are dealing with plants rooting in failed movement joints and weathered mastic that no longer stretches, we can put it right, on brickwork movement joints, façade panels and copings & trims alike.
In and around a place like Wasbister, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Common questions in Wasbister
Is Wasbister in your area for external mastic?
Yes. We work across all of Scotland, and Wasbister is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect external mastic in Wasbister?
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.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Aftercare tips
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What affects the quote in Wasbister
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- How many areas need sealing
- The old material and how stubborn it is
- How easy the joints are to reach
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
When you call or email, these details help:
- If someone has resealed it before
- The address or postcode of the job
- A few photos by email, if you can
- How many joints, rooms or windows are involved
We quote each job on its own, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job and send pictures if you have them.

What external mastic looks like in Wasbister
Wasbister is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Historic houses such as Skaill House, about 3.6 miles north-west, show how far back building around Wasbister goes, and older homes nearby need a sealant that suits their walls.
Wasbister is about 11 miles west of Kirkwall, in the Orkney Islands. From the centre of Wasbister to the outskirts, external mastic is available for homes and businesses alike. Wasbister is one of 51 places in the Orkney Islands where we work.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Around Wasbister, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Advice
Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In a place like Wasbister, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
