What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Around Doune, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Common problems we fix in Doune
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint.
Look out for any of the following:
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
In the older streets around St Madoc's Episcopal Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What to tell us for a quote
What to tell us when you ask for a quote:

- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- Where the property is
We quote each job on its own, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details, and photos are welcome.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In an older home around Doune, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep high-pressure jets off the joints
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
- Keep movement joints as flexible joints, not mortar
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
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.
What external mastic looks like in Doune
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. 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.
Rented homes near Dunblane station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
