External mastic in Cartsdyke, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. If you have movement joints with cracked, split or missing sealant and sealant that has lost its bond to the brick or render, we can put it right, on concrete & block, copings & trims and brickwork movement joints alike.
Outside joints can only be sealed when they’re dry, so work in Cartsdyke depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Do you need external mastic in Cartsdyke?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
For landlords with property near Whinhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we need to know
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- The address or postcode of the job
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.
Honest limits
To be straight with you, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Cartsdyke need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

FAQs for Cartsdyke
Does living near the coast affect external mastic in Cartsdyke?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Cartsdyke?
Yes. Cartsdyke is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
How long does the job take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Why act early in Cartsdyke
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What else we do in Cartsdyke
Outside joints around Cartsdyke
Cartsdyke is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around St Laurence’s Church (Greenock), old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Wellington Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How to look after the new joints
Aftercare is simple:
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
