About our external mastic in Carnbo
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on render & cladding joints, façade panels and concrete & block, and common reasons people get in touch are rigid filler in a joint that should flex and gaps where render, brick and frames meet.
External sealant needs dry surfaces, so outdoor work around Carnbo is planned around the weather. Tell us how to reach each wall, gutter and roofline.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In an older home around Carnbo, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we’ll talk you through it.

What we are called out for in Carnbo
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
For jobs in and around Carnbo, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Carnbo questions
Is Carnbo within the area you cover?
Yes, Carnbo is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is external mastic in Carnbo guaranteed?
All our work, in Carnbo and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

How we quote for external mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- Mould in or behind the old joints
- When we can work, for business premises
- Whether the work is at height
- How many rooms, windows or areas are involved
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before work begins.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- The problem you’ve noticed
- Roughly how big the job is
- The type of property
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will take it from there.
How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the building. Outdoor work around Carnbo depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Advice
Carnbo buildings and the weather
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Carnbo, as everywhere, external mastic is only as good as the preparation behind it.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Damp that is not coming from the joint
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
