About our external mastic in Tingwall
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, render & cladding joints and concrete & block, and common reasons people get in touch are cracked joints where brick meets render or frames and old sealant gone brittle and cracked.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You get a 12-month guarantee, the same in Tingwall as everywhere else we work.

Why it’s worth doing now in Tingwall
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Outside joints around Tingwall
Tingwall is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Whether the job is in Tingwall itself or nearby, the right material for each joint matters as much as a neat finish.
Tingwall is about 8 miles north-west of Kirkwall, in the Orkney Islands. Tingwall gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Tingwall is one of 51 places in the Orkney Islands we cover.

What we’re called out for in Tingwall
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.
Most people get in touch when they notice one of these:
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Panel joints letting water in
Around Tingwall, as everywhere, external mastic is only as good as the preparation behind it.
Questions to ask before booking
- Which colour the sealant will be
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Whether VAT is included
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Tingwall may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

FAQs for Tingwall
Does living near the coast affect external mastic in Tingwall?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Tingwall within the area you cover?
Yes, we do. 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.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
