Ardchonnell Window Mastic
Problem with your window and door frames in Ardchonnell? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Mastic that’s falling out in pieces
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
Window mastic in Ardchonnell
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, uPVC windows and timber windows & doors, and the jobs we see most are cracked sealant at the sill ends and rushed sealant from a window installation.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, you get the same one-year guarantee.

Window mastic in Ardchonnell: local notes
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Ardchonnell 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.
For an older house near a landmark such as Dalavich Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Ardchonnell is about 27 miles north-west of Helensburgh, in Argyll and Bute.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Do you need window mastic in Ardchonnell?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
These are the problems we’re asked about most:
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
- Untidy mastic left by window fitters
- Black, perished sealant on frames
Around Ardchonnell, as everywhere, window mastic is only as good as the preparation behind it.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
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. Catching it early keeps the fix to a reseal.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a morning for a couple of windows and a door, depending on how much there is to do. For a place like Ardchonnell, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
