How we handle external mastic in Inverinan
For buildings in Inverinan, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on brickwork movement joints, façade panels and render & cladding joints, and the jobs we see most are failed sealant between panels on a façade and rain getting behind render or cladding at a joint.
Outside joints can only be sealed when they’re dry, so work in Inverinan depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Every job comes with a 12-month guarantee.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. For a place like Inverinan, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in

Signs you need external mastic in Inverinan
Buildings move more than people expect. 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.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
In and around Inverinan, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Inverinan
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Around Inverinan, water from a failed joint in an older stone home can soak into timber and plaster.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

Common questions in Inverinan
Is external mastic in Inverinan guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Inverinan?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll tell you how long to expect.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
How long does external mastic last?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Outside joints around Inverinan
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Inverinan is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Whether the job is in Inverinan itself or nearby, the right material for each joint matters as much as a neat finish.

How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Keeping the joints in good condition
Aftercare is simple:
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
- Leave the joints unpainted unless we’ve said otherwise
- Fix overflowing gutters above sealed joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
Landlords, agents and businesses in Inverinan
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
