External mastic in Cullivoe, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you’re dealing with cracked joints where brick meets render or frames and hard, crazed mastic that has stopped moving, 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.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Aftercare tips
A little care helps the new joints last. Our advice:
- Check external joints each spring
- Point out the joints to other trades
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Surface by surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.
Landlords, agents and businesses in Cullivoe
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, the joints are inspected and the access agreed.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Questions from Cullivoe
Does living near the coast affect external mastic in Cullivoe?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover Cullivoe for external mastic?
Yes, Cullivoe is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. Your quote will say how long we expect yours to take.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Walls and rooflines in Cullivoe
Cullivoe is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s 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 Cullivoe, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Cullivoe is in the Shetland Islands. Cullivoe gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our the Shetland Islands coverage runs to 63 places, Cullivoe among them.
Here we cover the ZE2 postcode area for external mastic. You will find Cullivoe on the B9083, which makes it straightforward to reach. We also cover the places around Cullivoe: Clivocast (4 miles south-east), Baltasound (6 miles north-east), Camb (7 miles south), Mid Yell (8 miles south) and Haroldswick (9 miles north-east). If you’re somewhere remote, the job takes a little more planning, so let us know when you get in touch.
What’s near Cullivoe
The countryside around Cullivoe includes Valla Field and Loch of Papil.
When to call us in Cullivoe
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
The problems people usually mention when they call include:
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
For an older house near a landmark such as St Olaf's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before booking anyone
- How hidden problems are handled
- How the joint is cleaned and prepared
- Is VAT in the price?
- Whether all the old sealant comes out first

- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
