External mastic in Hardgate
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are rain getting behind render or cladding at a joint and cracked joints where brick meets render or frames.
Outside joints can only be sealed when they’re dry, so work in Hardgate depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What affects the quote in Hardgate
There’s no set price list, because jobs vary so much. The quote depends on:
- Access and height
- How many areas need sealing
- Working hours on commercial sites
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- Pictures of the joints, sent by email
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work before giving you a price.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Hardgate 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. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Why act early in Hardgate
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Hardgate, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What you get with us
- Approved under the ARBOMaster scheme
- Any old sealant cut out fully, not covered over
- Over 20 years’ experience
- We agree the colour with you first

Keeping the joints in good condition
So the new joints stay in good condition:
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
When to call us in Hardgate
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Look out for these signs:
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
If you live in an older home near Urr Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What external mastic looks like in Hardgate
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Around Hardgate, as everywhere, external mastic is only as good as the preparation behind it.

FAQs for Hardgate
Is Hardgate in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Hardgate is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Is there a guarantee on external mastic in Hardgate?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
How do I get a quote for external mastic in Hardgate?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
