Questions from Douglas
Who arranges sealant work on the shared parts of a tenement in Douglas?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
Is external mastic in a coastal place like Douglas any different?
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.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Do you work in Douglas?
Yes. We are based in Crawley and work across South East England, London and Scotland.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
About our external mastic in Douglas
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. Common call-outs are for old sealant gone brittle and cracked and cracked joints where brick meets render or frames, across render & cladding joints, concrete & block and copings & trims.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Douglas, those joints dry out over time and let water in behind the render or cladding.

Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In a tenement flat in Douglas, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What we’re called out for in Douglas
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.
It’s worth asking for a quote if you see:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Sealant that has lost its bond to the brick or render
If you let a flat or house near Broughty Ferry station, outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- Whether you can choose the colour
- Who does the work, and how experienced they are
- How hidden problems are handled
- When the joint can take water or movement
Outside joints around Douglas
Douglas 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces 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.
Schools such as Craigie High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Landlord and commercial work in Douglas
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Façade panels
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
Different surfaces, different methods
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Douglas, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
