DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
External mastic in Drumnadrochit, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you are dealing with sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant, we can put it right, on brickwork movement joints, render & cladding joints and façade panels alike.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- Working hours on commercial sites
- The old material and how stubborn it is
- The type of sealant required
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- Pictures of the joints, sent by email
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Signs you need external mastic in Drumnadrochit
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Most people get in touch when they notice one of these:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
For an older house near a landmark such as Kilmore Parish Church of Scotland, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Drumnadrochit: your questions answered
Is there a guarantee on external mastic in Drumnadrochit?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Drumnadrochit for external mastic?
Yes. Our work covers the whole of Scotland, and Drumnadrochit is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Do you do commercial work?

What information do you need?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Are you insured?
Yes. Mr Mastic is fully insured.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Drumnadrochit buildings and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
Managing a site like Glen Urquhart High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Around Drumnadrochit, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area

Related advice
Why act early in Drumnadrochit
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 problem grows beyond the joint itself. In an older home around Drumnadrochit, damp from a failed joint can get into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
