Norseman External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Norseman and across the Orkney Islands. Fully insured, ARBOMaster approved and guaranteed for a year.
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
What happens if it’s left?
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. A flexible sealant over backing rod is what the joint needs. 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.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What you get with us
- Anti-fungal silicone where joints get wet
- Homes, businesses and hotels
- Trusted Arbo and Everbuild sealants
- White, clear, grey or coloured to suit, where the product allows

External mastic for homes and businesses in Norseman
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on joints between brick and frames, façade panels and copings & trims, and the jobs we see most are rigid filler in a joint that should flex and sealant pulling away from one side of the joint.
External sealant needs dry surfaces, so outdoor work around Norseman is planned around the weather. Tell us how to reach each wall, gutter and roofline.
Our work is backed for twelve months, in Norseman and everywhere else we cover.

When something else is needed
A few problems are outside what sealant work can do:
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

Norseman: your questions answered
Is Norseman within the area you cover?
Yes, Norseman is covered. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Norseman in your area for external mastic?
Yes, Norseman 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, and we’ll give you a clear price.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Aftercare tips
After the cure time, these simple habits help:
- Check external joints each spring
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What we are called out for in Norseman
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for these signs:
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Leaking joints around cladding and façade panels
Around Norseman, as everywhere, external mastic is only as good as the preparation behind it.

Walls and rooflines in Norseman
Norseman 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
Whether the job is in Norseman itself or nearby, the right material for each joint matters as much as a neat finish.
Norseman is about 7 miles north-west of Kirkwall, in the Orkney Islands. We provide external mastic to homes and businesses in Norseman, as part of our work across the Orkney Islands. We cover 51 towns and villages across the Orkney Islands, from the larger towns to small villages.
We work across KW17 for external mastic. Close by, we work in Isbister (1 mile east), Settiscarth (1 mile west), Gorseness (2 miles north-east), Tingwall (3 miles north-east) and Finstown (3 miles south). Island and remote addresses take a little more planning, so please mention your location when you email us at info@mrmastic.co.uk.
Landmarks near Norseman
A little further out are Corrigall Farm Museum (3.4 miles west) and Langskaill House (4.1 miles north-east). Open spaces near Norseman include Ward of Redland and Loch of Brockan.
Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on the size of the job. Outdoor work around Norseman depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
