Window mastic in Calton
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before any work starts. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached for window mastic in Calton. We work on patio & French doors, window sills and uPVC windows, and common reasons people get in touch are sealant in the wrong colour for the frame and damp patches on the reveal after heavy rain.
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 Calton, access is the first thing to plan.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How it works
The work is kept neat and contained to the area we are working on. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are. For a tenement in Calton, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any parking rules near the property
- Move anything stored near the joints

Calton questions
I let a flat near Bellgrove station. Can you help?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
How do repairs to the shared parts of a tenement in Calton get organised?
It usually 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, and we can quote for the factor or the owners directly.
Where are you based?
We work from Crawley. Our applicators cover Calton.
Can you match the sealant to my frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Does the work come with a guarantee?
Yes. Every job comes with our one-year guarantee, and we are fully insured.
Different surfaces, different methods
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Common problems we fix in Calton
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
These are the problems we’re asked about most:
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
Letting a property close to Bellgrove station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Calton homes and the weather
Calton is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Calton New Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Check the mastic once a year
- Wipe condensation off the frames
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Why it’s worth doing now in Calton
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Calton, damp can travel a long way before it shows.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
