Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What else we do in Reddingmuirhead
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outdoor work around Reddingmuirhead depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

How we quote for external mastic
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- The product the joint needs
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
What to tell us when you ask for a quote:
- Roughly how big the job is
- Any previous sealing or DIY work
- Where the job is, and your postcode
- Pictures of the joints, sent by email
Every job is quoted individually, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Concrete & block
What the job involves on each surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best.
External mastic in Reddingmuirhead: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Polmont station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Graeme High School? Then larger buildings have long runs of movement joint that eventually need resealing.

What we’re called out for in Reddingmuirhead
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Most people get in touch after spotting one of these:
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
Homes close to Brightons Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Whether they’re fully insured
- Who turns up on the day
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
Common questions in Reddingmuirhead
Can you help a landlord with a rental near Polmont station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Is Reddingmuirhead within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before any work starts.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Why it’s worth doing now in Reddingmuirhead
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
