What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- A sash or casement that won’t close properly
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)

What window mastic looks like in Portsoy
Portsoy is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In the older streets around St John's Episcopal Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Around Portsoy, as everywhere, window mastic is only as good as the preparation behind it.

Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In an older home around Portsoy, damp from a failed joint can get into timber and plaster.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why choose Mr Mastic in Portsoy
- Domestic, commercial and hotel work
- White, clear, grey or another colour, product permitting
- We never seal over old sealant
- Colour agreed with you before work begins
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
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.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not use solvent cleaners on the joint
- Check the mastic once a year
- Wipe condensation off the frames
- Do not paint over the silicone
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
