External mastic for homes and businesses in Bonnyton
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. Common call-outs are for sealant that has lost its bond to the brick or render and joints pointed up with cement by mistake, across façade panels, joints between brick and frames and concrete & block.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee, large or small.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What else we do in Bonnyton
Bonnyton buildings and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Bonnyton is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Letting a property close to Kilmarnock station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Historic houses such as Girgenti House, about 4.6 miles north-west, show how far back building around Bonnyton goes.

When it is not the sealant

- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
- Render that’s blown, hollow or coming away

Surfaces we seal
- Façade panels
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Concrete & block
Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. 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.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Common questions in Bonnyton
Do you cover Bonnyton for external mastic?
Yes, Bonnyton is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Bonnyton?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
How much does external mastic cost in Bonnyton?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
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. Brands we use include Arbo and Everbuild.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Bonnyton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

Advice
Signs you need external mastic in Bonnyton
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Any of these means the joints need attention:
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
Managing a site like Grange Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
