About our external mastic in Montrose
For buildings in Montrose, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on façade panels, brickwork movement joints and render & cladding joints, and people most often call us about rigid filler in a joint that should flex and weeds or debris growing in open joints.
Scottish weather is hard on outside joints, and a town like Montrose gets its share of wind and rain. Gaps in gutter joints, fascias and wall joints are where damp starts.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In flats with a shared stair in Montrose, a leak from a failed seal can affect the flat below too, which turns a small job into a bigger one.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

FAQs for Montrose
Can you do external mastic in Montrose?
Yes. We work across all of Scotland, and Montrose is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Does the coastal weather in Montrose affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Honest limits
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Failed render or damaged cladding panels
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What we are called out for in Montrose
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
Rented homes near Montrose station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How the joint is cleaned and prepared
- Whether you can choose the colour
- Is the old sealant removed completely?
- Whether the sealant suits the joint

Outside joints around Montrose
Montrose 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Managing a site like Montrose Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
