Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on window sills, composite doors and uPVC windows, and people most often call us about mastic that has split away from the wall and a bead that doesn’t match the frame.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in South Gyle, and in a tenement the outside of the building may be a shared repair.
Each job carries a 12-month guarantee, large or small.

When something else is needed
In fairness, there are a few things sealant will not fix:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame

South Gyle homes and the weather
South Gyle is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s 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. Windows generally belong to the flat, but the title deeds have the final say.
Schools such as Forrester High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near South Gyle station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in South Gyle
Who arranges sealant work on the shared parts of a tenement in South Gyle?
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. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you help a landlord with a rental near South Gyle station?
Yes. We work for landlords and agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Wipe condensation off the frames
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.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

What else we do in South Gyle
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. For landlords in South Gyle, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
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.
Why us?
- We’re fully insured
- An ARBOMaster approved applicator
- Old sealant always removed completely
- Every job guaranteed for a year

Do you need window mastic in South Gyle?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Keep an eye out for these signs:
- Old mastic that has gone black or come away
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
Historic houses such as Caroline Park, about 4 miles north-east, show how far back building around South Gyle goes, and older homes nearby need a sealant that suits their walls.
Questions to ask before booking
- Whether all the old sealant comes out first
- Who turns up on the day
- How the surfaces are prepared before sealing
- How hidden problems are handled
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
