Signs you need external mastic in Barassie
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
The problems people usually mention when they call are:
- Joints pointed up with cement by mistake
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
Schools such as Marr College are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

How we handle external mastic in Barassie
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. If you have panel joints letting water in and rain getting behind render or cladding at a joint, we can help, on copings & trims, façade panels and concrete & block alike.
External sealant needs dry surfaces, so outdoor work around Barassie is planned around the weather. Let us know about access to every wall and roofline.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Quotes for external mastic in Barassie
We do not publish a price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- Which sealant suits the joint
- How many areas need sealing
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- How many joints, rooms or windows are involved
- The type of property
- Photos by email, if that’s easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
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 near the open joint, so the problem grows beyond the joint itself. In a place like Barassie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

Questions from Barassie
Can you help a landlord with a rental near Barassie station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Does living near the coast affect external mastic in Barassie?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll say how long yours will take.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Walls and rooflines in Barassie
Barassie is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For landlords with property near Barassie station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Outside jobs in Barassie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t 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.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
- Check external joints each spring
- Wash walls gently around the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
