How we handle window mastic in Dunblane
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on uPVC windows, aluminium frames and timber windows & doors, and common reasons people get in touch are mastic that’s falling out in pieces and untidy mastic left by window fitters.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
A one-year guarantee comes as standard, so you are covered after we have gone.

Questions from Dunblane
Will you come out to Dunblane?
Yes. Dunblane is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Dunblane 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 will give you a fixed price before any work starts.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
How long does it take to reseal the windows on a house?
The work takes a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal.
Frames and glazing around Dunblane
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Dunblane, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Composite doors
- uPVC windows

Common problems we fix in Dunblane
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
People usually contact us when they notice something like this:
- Water coming in at the bottom corners of a door
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- Mastic that’s falling out in pieces
For landlords with property near Dunblane station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- How much experience the applicator has
- Whether you can choose the colour
- What happens if the job turns out different
- Are they insured?
Keeping the joints in good condition
So the new joints stay in good condition:
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames don’t stay wet inside
- Keep jet washers away from the mastic
- Look round the frames every year or so
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.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
