About our external mastic in Claddach Kyles
On houses, flats and commercial buildings across Claddach Kyles, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have failed seals between different materials and sealant pulling away from one side of the joint, we can help, whatever the surface.
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.
Whatever the size of the job, it’s backed by our one-year guarantee.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
What we are called out for in Claddach Kyles
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The most common problems we see are:
- Old sealant gone brittle and cracked
- Sealant pulling away from one side of the joint
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
Around Claddach Kyles, as everywhere, external mastic is only as good as the preparation behind it.

What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. In a place like Claddach Kyles, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.
Why us?
- A choice of colours where the product allows
- We leave the area clean and tidy
- Anti-fungal silicone where joints get wet
- We never seal over old sealant

The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

How long does external mastic last?

Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
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.
How long does external mastic take?
That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
