FAQs for Addiebrownhill
Do you cover smaller places like Addiebrownhill?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Addiewell station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
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.
How do I get a quote for external mastic in Addiebrownhill?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall. If it has already been filled, we can usually cut it out and reseal it.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
External mastic in Addiebrownhill
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we do not skip that step. We are often asked to deal with panel joints letting water in and failed seals between different materials, across render & cladding joints, brickwork movement joints and joints between brick and frames.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Surface 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.
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.
Walls and rooflines in Addiebrownhill
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Addiewell station, split movement joints are easy to miss on a rental until damp shows inside.

What we are called out for in Addiebrownhill
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.
Most people get in touch after spotting one of these:
- Failed seals between different materials
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
In the older streets around Addiewell Church Of Scotland, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What else we do in Addiebrownhill
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The type of sealant required
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.
Asking for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- The problem you’ve noticed
- A few pictures by email, if you can
- Any access issues, like height or stairs
Need a quote? Please drop us a line at info@mrmastic.co.uk with a few details. We’ll explain what we’d do and give you a clear price before any work starts.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Outside jobs in Addiebrownhill need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Tell us if parking is tricky
