External mastic for homes and businesses in Grange
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you are dealing with plants rooting in failed movement joints and cracked joints where brick meets render or frames, we can put it right, on render & cladding joints, façade panels and copings & trims alike.
In and around a place like Grange, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Grange: your questions answered
Is Grange in your area for external mastic?
Yes. We work across all of Scotland, and Grange is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect external mastic in Grange?
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.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Perth and Kinross.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Why act early in Grange
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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why book with us
- An ARBOMaster approved applicator
- We agree the colour with you first
- White, clear, grey or another colour, product permitting
- Sealant colour chosen to suit
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Render that’s blown, hollow or coming away
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal
- Façade panels

External mastic in Grange: local notes
Grange 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Around Grange, as everywhere, external mastic is only as good as the preparation behind it.

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around Grange 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 checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Advice
What we are called out for in Grange
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The problems people normally mention when they call include:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
Whether the job is in Grange itself or nearby, the right material for each joint matters as much as a neat finish.
