Window Mastic in Baldernock
Problem with your window and door frames in Baldernock? We remove the old material, prepare the joints and seal them properly.
- Damp patches on the reveal after heavy rain
- Cracked or shrunken mastic around the frame
- Cold air getting in at the frame edge
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
How we handle window mastic in Baldernock
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. If you have gaps where the sill meets the wall and mastic that’s falling out in pieces, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- Faulty window hardware
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Aluminium frames

- Window sills
- Timber windows & doors
- Composite doors
Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In an older home around Baldernock, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why us?
- Every job guaranteed for a year

- Anti-fungal silicone where joints get wet
What else we do in Baldernock
Do you need window mastic in Baldernock?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
These are the problems we are asked about most:
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
Managing a site like Boclair Academy? Then the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How the colour is chosen
- Is VAT in the price?
- How long to leave it before use
- How hidden problems are handled
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a morning for a couple of windows and a door. Outdoor work around Baldernock depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
How to get a quote

Baldernock homes and the weather
The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In the older streets around Baldernock Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Milngavie station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Questions from Baldernock
Do you cover Baldernock for window mastic?
Yes. Our work covers the whole of Scotland, and Baldernock is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Will you come out to Baldernock?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
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 do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
