External mastic in Gordon, done properly
On houses, flats and commercial buildings across Gordon, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include failed sealant between panels on a façade and joints pointed up with cement by mistake, across façade panels, concrete & block and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Gordon depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Each job carries a 12-month guarantee, whatever its size.

Common problems we fix in Gordon
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Look out for any of the following:
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
Homes close to East Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What to look for in a quote
- Are they insured?
- Is VAT in the price?
- What happens if they find a problem under the old sealant

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Landlord and commercial work in Gordon
We also work for property managers and facilities teams. Several sites can be quoted together.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

What we need to know
You don’t need to know the technical terms. Just tell us:
- Where the property is
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, email us at info@mrmastic.co.uk.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Gordon buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. 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.
