External mastic in Strichen, done properly
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have weathered mastic that no longer stretches and panel joints letting water in, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
Each job carries a 12-month guarantee, whatever its size.

Why it’s worth doing now in Strichen
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Around Strichen, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

Signs you need external mastic in Strichen
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
These are the problems we’re asked about most:
- Water getting into walls through failed joints
- Panel joints letting water in
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
In and around Strichen, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Common questions in Strichen
Do you cover smaller places like Strichen?
Yes, Strichen is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in Strichen guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Should I try it myself first?
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 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.
The process
Our applicators work methodically: 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 and we leave things clean and tidy. Around Strichen, 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.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

External mastic in Strichen: local notes
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. 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.
For an older house near a landmark such as All Saints' Episcopal Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

In fairness, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
