External mastic in Pilton
For buildings in Pilton, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We are often asked to deal with gaps where render, brick and frames meet and panel joints letting water in, across copings & trims, render & cladding joints and façade panels.
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 Pilton, access needs planning, and work on shared parts may need the other owners’ agreement.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Outside joints around Pilton
Pilton 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.
Historic houses such as Caroline Park, about 0.7 miles north, show how far back building around Pilton goes, and older homes nearby need a sealant that suits their walls. If you look after a building such as Ainslie Park High School, its movement joints, gutters and trims need looking after like any other building’s.
Pilton is about 2 miles north-west of Edinburgh, in Edinburgh. We carry out external mastic for homes and businesses in Pilton, as part of our work across Edinburgh. Our area takes in 175 places across Edinburgh, large and small.
Jobs for external mastic in EH5, EH4 and EH3 works the same way as everywhere else we cover. If you need external mastic at a property on Ferry Road, Grigor Avenue and Davidson Road or anywhere close by, our applicators can take on the job. We also cover Crewe Toll (1 mile south), Granton (1 mile north-east), East Pilton (1 mile south), West Pilton (1 mile west) and Edinburgh Waterfront (1 mile north). Larger places within reach include Leith (3 miles east), Buccleuch (3 miles south-east), Dumbiedykes (3 miles south-east), Sciennes (3 miles south-east), Merchiston (3 miles south-east) and Newington (3 miles south-east).
Near you in Pilton
In Pilton, that means homes and buildings near Starbank Park, St Columba's Parish Church and Stockbridge public library and the streets around them. The closest station to Pilton is Haymarket station, roughly 2 miles south. Other landmarks nearby include Craigcrook Castle (1.6 miles south-west) and Western General Hospital (0.7 miles south). Not far away are Corstorphine Hill and Dunsapie Loch.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Leave the joints unpainted unless we’ve said otherwise
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
What we’re called out for in Pilton
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Look out for any of the following:
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
Letting a property close to Haymarket station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- Whether you can choose the colour
- What insurance they hold
- What the quote includes, VAT included or not
- Who turns up on the day
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
Where we work in Pilton
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Concrete & block
What the job involves on each 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.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How the visit works
At the end, we look at the finished work together. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Pilton, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
Getting a quote
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.

Pilton questions
Is external mastic in a coastal place like Pilton any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How is work on the outside of a tenement in Pilton generally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
How long does external mastic take?
Most jobs take 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.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
