Claddach Kyles Window Mastic
Window and door frames in Claddach Kyles need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
Common problems we fix in Claddach Kyles
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
In and around Claddach Kyles, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Window mastic in Claddach Kyles
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. We are often asked to deal with black, perished sealant on frames and gaps between the frame and the inside reveal, on aluminium frames, window sills and timber windows & doors.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job is covered by a one-year guarantee, wherever you are in Na h-Eileanan Siar.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

What window mastic looks like in Claddach Kyles
Claddach Kyles 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. Claddach Kyles is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
For jobs in and around Claddach Kyles, choosing the right material for each joint is as important as a tidy finish.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep timber frames painted
- Check the mastic once a year
- Do not paint over the silicone
- Clean frames with a soft cloth and soapy water
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Honest limits
A few problems are outside what sealant work can do:
- Faulty window hardware
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Claddach Kyles.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Surface by surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
