Window mastic in Balmedie, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. Common call-outs are for mastic that’s falling out in pieces and mastic that has split away from the wall, across window sills, uPVC windows and patio & French doors.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months, in Balmedie and everywhere else we cover.

FAQs for Balmedie
Is window mastic in a coastal place like Balmedie any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

When to call us in Balmedie
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Most people get in touch after spotting something like this:
- Gaps left after new windows were fitted
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
In the older streets around Belhelvie North Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes most of a day for a typical house, less for a few frames. Outside jobs in Balmedie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What affects the cost of window mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- The amount of work
- When we can work, for business premises
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
When you contact us, these details help:
- A few photos by email, if you can
- The address or postcode of the job
- If someone has resealed it before
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

What window mastic looks like in Balmedie
Balmedie is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
In and around Balmedie, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
