How we handle external mastic in Auchenhowie
For buildings in Auchenhowie, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with sealant that has lost its bond to the brick or render and movement joints filled with mortar instead of sealant, we can put it right, on concrete & block, joints between brick and frames and copings & trims alike.
External sealant needs dry surfaces, so outdoor work around Auchenhowie is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a 12-month guarantee.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Common problems we fix in Auchenhowie
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Look out for any of the following:
- Joints with sealant missing in places
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
Managing a site like Boclair Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- How long the guarantee is
- Whether VAT is included
- What product goes in the joint
- How the surfaces are prepared before sealing
External mastic in Auchenhowie: local notes
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. Historic houses like Tenement House (about 4.7 miles south) are a reminder that the area around Auchenhowie has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as St Paul’s Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Milngavie station, split movement joints are easy to miss on a rental until damp shows inside.

Auchenhowie: your questions answered
Is Auchenhowie within the area you cover?
Yes. Auchenhowie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Milngavie station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Are you insured?
Yes. We are fully insured.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
What sealant work cannot fix
We will always be straight with you, so here’s what new sealant will not do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The amount of work
- Mould in or behind the old joints

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Act on the first splits you see
- Check the sealant is paintable before painting near it
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
If you manage several properties in or around Auchenhowie, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
What happens on the day
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 normally takes a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Auchenhowie depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
