Ceann Tangabhal: your questions answered
Does the coastal weather in Ceann Tangabhal affect outside sealant?

How we handle window mastic in Ceann Tangabhal
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we will say so. If you’re dealing with rushed sealant from a window installation and draughts coming in around windows and doors, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Windows and doors in Ceann Tangabhal
Ceann Tangabhal is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
If you look after a building such as Castlebay Community School, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Common problems we fix in Ceann Tangabhal
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That is what backing rod is for.
Look out for these signs:
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
Homes close to Church of our Lady include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. Outdoor work around Ceann Tangabhal depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Clear the area around the work

Related advice
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
