- Rushed sealant from a window installation
Window mastic for homes and businesses in Barnton
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Typical jobs include rain getting in at the frame or under the sill and gaps where the sill meets the wall, on uPVC windows, window sills and composite doors.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Window mastic in Barnton: local notes
Barnton 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 the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Edinburgh Gateway station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Craigmount High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on

- uPVC windows
What happens if it’s left?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. 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.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
FAQs for Barnton
I let a flat near Edinburgh Gateway station. Can you help?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
How do repairs to the shared parts of a tenement in Barnton get organised?
The owners of the flats normally 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. Your title deeds will say who owns the windows.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Inside a flat in Barnton, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- Tell us about any water getting in

How we quote for window mastic
We don’t publish a price list. The quote depends on:
- Whether old sealant or filler has to be cut out
- How much there is to do
- The type of sealant required
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
We quote each job on its own, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Do not use solvent cleaners on the joint
- Wash the frames with mild soapy water
- Check the mastic once a year
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Do you need window mastic in Barnton?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Keep an eye out for these signs:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- A bead that does not match the frame
- Rushed sealant from a window installation
Historic houses such as Caroline Park, about 2.9 miles north-east, show how far back building around Barnton goes, and older homes nearby need a sealant that suits their walls.
