What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- How many areas need sealing
- The old material and how stubborn it is
- Whether there’s mould to deal with
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Where the property is
- Photos by email, if that is easy
- Roughly how big the job is
- What’s wrong with the joints now

External mastic in Stenhouse
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. If you are dealing with leaking joints around cladding and façade panels and rigid filler in a joint that should flex, we can put it right, whatever the surface.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. For a tenement in Stenhouse, repairs to shared parts are normally agreed between the owners, often through a property factor.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What else we do in Stenhouse
Common questions in Stenhouse
Is external mastic in a coastal place like Stenhouse any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Who arranges sealant work on the shared parts of a tenement in Stenhouse?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Do you come to Stenhouse?
We do. Stenhouse is part of the area we cover.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
What external mastic looks like in Stenhouse
Stenhouse 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. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. For listed homes and conservation areas, check with the council before changing how windows or walls look.
Letting a property close to Slateford station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Balgreen Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Caroline Park, about 3.5 miles north, show how far back building around Stenhouse goes.
Stenhouse is about 2 miles west of Edinburgh, in Edinburgh. We carry out external mastic for householders, landlords and businesses in Stenhouse and nearby, as part of our work across Edinburgh. Stenhouse is one of 175 places in Edinburgh where we work for external mastic.

Main roads around Stenhouse include the A71. Other places close to Stenhouse include Saughton (1 mile south-west), Carrick Knowe (1 mile north-west), Chesser (1 mile south-east), Parkhead (1 mile south) and Longstone (1 mile south). We also work in nearby towns such as Leith (5 miles north-east), Bonnington (4 miles north-east), Greenside (3 miles north-east), Broughton (3 miles north-east), Bellevue (3 miles north-east) and Silvermills (3 miles north-east).
Local landmarks in Stenhouse
We work in homes and buildings around Cross Keys Tavern, Gabrielle Keiller Library and Scotus Academy and the streets around them. Nearby too are Merchiston Castle School (1.4 miles south) and Saughton Park (under half a mile east). The nearest railway station is Slateford station, about 0.8 miles south-east. Well-known places in the area include Corstorphine Hospital (0.8 miles north-west) and Craigcrook Castle (1.6 miles north). For a walk, there’s Craiglockhart Hill and Dunsapie Loch.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What we cannot put right
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Concrete & block
- Copings & trims

Landlords, agents and businesses in Stenhouse
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before we start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Stenhouse, tell us the floor, how the door entry system works and where we can park nearby.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
