External mastic in Milngavie
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. Common call-outs are for gaps where render, brick and frames meet and failed sealant between panels on a façade, across concrete & block, brickwork movement joints and copings & trims.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building. Outside jobs in Milngavie need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
Before we arrive
- Clear the area around the work
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

Yes. Several rooms, windows or areas can go on one quote.
Outside joints around Milngavie
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. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
For site and facilities teams at buildings such as Douglas Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Milngavie station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Structural movement, which needs a surveyor or engineer
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Copings & trims
- Façade panels
Why it’s worth doing now in Milngavie
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Keeping the joints in good condition
Looking after new joints is easy:
- Act on the first splits you see
- Point out the joints to other trades
- Check external joints each spring
- Check the sealant is paintable before painting near it
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
