What affects the quote in South Portobello
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- Which sealant suits the joint
- The size of the job
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. Just tell us:
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
For a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
Window mastic in South Portobello, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for rain getting in at the frame or under the sill and whistling draughts around closed windows, on aluminium frames, uPVC windows and composite doors.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. For a flat in South Portobello, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
Whatever the size of the job, you get the same one-year guarantee in South Portobello and across Edinburgh.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Clear any debris from frame drain holes
- Clean frames with a soft cloth and soapy water
- Avoid harsh chemicals near the mastic
- Look round the frames every year or so
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What window mastic looks like in South Portobello
South Portobello is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
Managing a site like Portobello High School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St John the Evangelist RC Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Patio & French doors
- Composite doors
- Timber windows & doors
- Window sills
Common problems we fix in South Portobello
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Most people get in touch when they notice something like this:
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
- White mastic on grey or black frames
- Black, perished sealant on frames
If you let a flat or house near Brunstane station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Are they insured?
- Whether VAT is included
- Is the old sealant removed completely?
- How much experience the applicator has

Advice
South Portobello: your questions answered
How do repairs to the shared parts of a tenement in South Portobello get organised?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Is window mastic in a coastal place like South Portobello 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.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you guarantee window mastic?
Yes. Every job comes with our 12-month guarantee, and we are ARBOMaster approved applicators.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can new window sealant be painted?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Why it’s worth doing now in South Portobello
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in South Portobello, damp can travel a long way before it shows.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why book with us
- Any old sealant cut out fully, not covered over
- More than 20 years in sealant work
- Anti-fungal sanitary silicone in wet areas
- Quality sealants from Arbo and Everbuild
