About our external mastic in Holm
For buildings in Holm, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you are dealing with weathered mastic that no longer stretches and brick movement joints where the sealant has split, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee, whatever its size.

Do you need external mastic in Holm?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
Whether the job is in Holm itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- The length of the guarantee
- Whether VAT is included
- How the surfaces are prepared before sealing
- How much experience the applicator has
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Holm questions
Do you cover Holm for external mastic?
Yes. Our work covers the whole of Scotland, and Holm is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Will you come out to Holm?
Yes. Holm is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
How often do external joints need resealing?
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.
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a place like Holm, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why us?
- We leave the area clean and tidy
- An ARBOMaster approved applicator

Outside joints around Holm
Holm is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. On the islands, wind and salt spray are hard on outside sealant.
In and around Holm, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
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.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.

DIY sealant or a professional job?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How it works
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. Around Holm, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
