Quotes for external mastic in Wishaw
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- The old material and how stubborn it is
- Mould in or behind the old joints
- The size of the job
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

About our external mastic in Wishaw
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We’re often asked to deal with leaking joints around cladding and façade panels and joints pointed up with cement by mistake, across façade panels, copings & trims and render & cladding joints.
Scottish weather is hard on outside joints, and a town like Wishaw gets its share of wind and rain. Gaps in gutter joints, fascias and wall joints are where damp starts.
Each job carries a 12-month guarantee, whatever its size.

Walls and rooflines in Wishaw
Under the Repairing Standard, private landlords in Scotland have to keep homes 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.
Homes close to Old Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Wishaw station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as St Aidan's High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. In a Scottish town like Wishaw, parking is normally straightforward, though older centres can be tighter. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Leave it or put it right?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. If you live in a flat in Wishaw, failed sealant can send water to the neighbours below, and that’s much harder to put right.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What you get with us
- We’re fully insured
- Sealant colour chosen to suit
- 12-month guarantee on every job
- An ARBOMaster approved applicator
Aftercare tips
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
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.
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before the bead.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
For landlords and businesses
For anyone letting property in or around Wishaw, several properties can be quoted together. Just tell us the addresses and what each one needs.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
