Window & door mastic in Mastrick, Aberdeen
Problem with your window and door frames in Mastrick? We remove the old material, prepare the joints and seal them properly.
- Mastic that has split away from the wall
- A bead that does not match the frame
- Cracked internal joints between frame and plaster
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames. In a city area like Mastrick, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

About our window mastic in Mastrick
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, uPVC windows and aluminium frames, and people most often call us about a bead that doesn’t match the frame and damp patches on the reveal after heavy rain.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. For a flat in Mastrick, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
All of our work is guaranteed for twelve months, in Mastrick and everywhere else we cover.

Aftercare tips
A little care helps the new joints last. Our advice:
- Keep paint off silicone joints
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Why deal with it now?
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. For landlords in Mastrick, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Signs you need window mastic in Mastrick
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
- Draughty joints inside around the window
Historic houses such as Friendville, about 1.9 miles south-east, show how far back building around Mastrick goes.

What else we do in Mastrick
Mastrick: your questions answered
Is Mastrick in your area for window mastic?
Yes, Mastrick is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you work for landlords with property near Aberdeen station?
Yes, we work for letting agents and landlords. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
How long will my window job take?
A handful of frames is a short visit. We confirm the timing with your quote.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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, and the work is guaranteed for a year.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

Windows and doors in Mastrick
Aberdeen’s nickname, the Granite City, comes from its stone buildings, and sealing against granite needs clean, sound edges and a sealant that suits stone. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Managing a site like Northfield Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Aberdeen station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
