External mastic for homes and businesses in Gayfield
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We’re often asked to deal with failed seals between different materials and brick movement joints where the sealant has split, across concrete & block, brickwork movement joints and joints between brick and frames.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. In Gayfield, access needs planning, and work on shared parts may need the other owners’ agreement.
There’s a 12-month guarantee on every job.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the 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.
Walls and rooflines in Gayfield
Gayfield is close to 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 Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. The title deeds set out which parts are common.
For an older house near a landmark such as Broughton Place Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Edinburgh Waverley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. For landlords in Gayfield, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

How it works
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. For a tenement in Gayfield, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- The amount of work
- The type of sealant required
- Mould in or behind the old joints
- The old material and how stubborn it is
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- If someone has resealed it before
- A few photos by email, if you can
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Do you need external mastic in Gayfield?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
Managing a site like London Street Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Is VAT in the price?
- What guarantee comes with the work
- When the joint can take water or movement
- What happens if they find a problem under the old sealant

Aftercare tips
Good habits help new joints last longer. A few tips:
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Gayfield: your questions answered
I let a flat near Edinburgh Waverley station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Gayfield?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will say how long yours will take.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch. If it has already been filled, we can generally cut it out and reseal it.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
