About our external mastic in Halkirk
On houses, flats and commercial buildings across Halkirk, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We are often asked to deal with panel joints letting water in and rain getting behind render or cladding at a joint, on façade panels, concrete & block and joints between brick and frames.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Whatever the size of the job, you get the same one-year guarantee in Halkirk and across Highland.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, 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.

What we’re called out for in Halkirk
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
If you live in an older home near Church of Scotland, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before you book anyone
- How much experience the applicator has
- Whether all the old sealant comes out first
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
Halkirk buildings and 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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. Somewhere like Halkirk may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints

Advice
Landlord and commercial work in Halkirk
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
FAQs for Halkirk
Is Halkirk within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Halkirk for external mastic?
Yes. Our work covers the whole of Scotland, and Halkirk is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What colours does the sealant come in?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Where do you work from?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Halkirk, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
