About our window mastic in Ardentinny
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Typical jobs include sealant in the wrong colour for the frame and rain getting in at the frame or under the sill, across aluminium frames, window sills and uPVC windows.
In and around a place like Ardentinny, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Windows and doors in Ardentinny
Ardentinny 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. Ardentinny 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.
Homes close to Ardentinny Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames don’t stay wet inside
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
What we’re called out for in Ardentinny
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Untidy mastic left by window fitters
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Mastic that’s falling out in pieces
For landlords with property near Garelochhead station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Can I paint over the new sealant?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.

Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
