Window mastic in Glenancross, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on uPVC windows, timber windows & doors and window sills, and the jobs we see most are water coming in at the bottom corners of a door and a bead that doesn’t match the frame.
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.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- The product the joint needs
- The amount of work
- The number of rooms or windows
- Any mould that needs treating
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
Silicone can’t generally be painted, so mention any painting plans before we start. We can use a paintable sealant where that matters.
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.
When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

What else we do in Glenancross
Windows and doors in Glenancross
Glenancross is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Glenancross is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Letting a property close to Morar station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Do you need window mastic in Glenancross?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Draughty joints inside around the window
Around Glenancross, as everywhere, window mastic is only as good as the preparation behind it.

Questions from Glenancross
I let a flat near Morar 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.
Does living near the coast affect window mastic in Glenancross?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
How long will my window job take?
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.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, inside or out.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Why it’s worth doing now in Glenancross
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. Around Glenancross, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. Outdoor work around Glenancross depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
