Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Window mastic in Balfour
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on patio & French doors, composite doors and aluminium frames, and the jobs we see most are untidy mastic left by window fitters and gaps where the sill meets the wall.
In and around a place like Balfour, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All our work is covered by a 12-month guarantee, wherever you are in the Orkney Islands.

Landlord and commercial work in Balfour
For anyone letting property in or around Balfour, several properties can go on one quote. Send us the addresses and the work at each.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
What we can’t put right
In fairness, some problems need a different trade:
- A failed sealed unit that has misted up
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on
- Timber windows & doors
- Composite doors
- Aluminium frames
- Window sills
- Patio & French doors
- uPVC windows
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Access and height
- The product the joint needs
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Helping us quote
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Where the property is
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
If you are in Balfour and need window mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and you’ll get a clear quote before we start.
Signs you need window mastic in Balfour
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- White mastic on grey or black frames
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Black, perished sealant on frames
For jobs in and around Balfour, choosing the right material for each joint is as important as a tidy finish.

How to look after the new joints
So the new joints stay in good condition:
- Keep paint off silicone joints
- Wipe condensation off the frames
- Keep timber frames painted
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. Around Balfour, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any tricky access
- Keep pets and children clear of the area while we work

Advice
Balfour: your questions answered
Is Balfour in your area for window mastic?
Yes, Balfour is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Balfour?
Yes, Balfour is covered. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Balfour homes and the weather
Balfour is close to 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Balfour, as everywhere, window mastic is only as good as the preparation behind it.
