What the job involves on each surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Window mastic for homes and businesses in Kincorth
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Common call-outs are for mastic that’s falling out in pieces and leaking joints at the ends of sills, on composite doors, timber windows & doors and patio & French doors.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you are in a tenement flat or a house in Kincorth, the joint between frame and wall is what keeps the weather out.
We stand behind the work with a one-year guarantee.

Advice
Window mastic in Kincorth: local notes
Kincorth 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. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
Rented homes near Aberdeen station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Ruthrieston South Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Kincorth is about 2 miles south of Aberdeen, in Aberdeen. Anywhere in AB12, we cover window mastic for homes and businesses. Kincorth is one of 63 towns and villages in Aberdeen where we work.
Every address in AB12 and AB10 is covered for window mastic. Whether your property is on Laws Road, Deeside Lane and Gardner Road or a nearby road, we can help.

Common problems we fix in Kincorth
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Look out for any of the following:
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
- A bead that does not match the frame
Schools such as Lochside Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Questions from Kincorth
Does the coastal weather in Kincorth affect outside sealant?
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.
How is work on the outside of a tenement in Kincorth generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Composite doors
- Patio & French doors
- Aluminium frames
- uPVC windows
- Timber windows & doors
- Window sills
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t use solvent cleaners on the joint
- Clean frames with a soft cloth and soapy water
- Keep timber frames painted
- Clear any debris from frame drain holes
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
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.
Why it’s worth doing now in Kincorth
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In a tenement flat in Kincorth, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
