External mastic for homes and businesses in Hogaland
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have failed seals between different materials and weathered mastic that no longer stretches, we can help, whatever the surface.
External sealant needs dry surfaces, so outdoor work around Hogaland is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You’re covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

What we’re called out for in Hogaland
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
If you live in an older home near Ollaberry Church and Churchyard with Monument, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a place like Hogaland, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about any water getting in
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Hogaland, water from a failed joint in an older stone home can soak into timber and plaster.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How the job changes by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
When something else is needed
It helps to know what we can’t do:
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

Outside joints around Hogaland
Hogaland 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’s hard on movement joints and outside wall joints, especially on the side facing the sea. On the islands, wind and salt spray are hard on outside sealant.
Around Hogaland, as everywhere, external mastic is only as good as the preparation behind it.

Questions from Hogaland
Do you cover Hogaland for external mastic?
Yes, Hogaland is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Hogaland?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
What does external mastic cost?
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.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on the first splits you see
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Make sure movement joints aren’t pointed over
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
