About our window mastic in Kilmuir
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you’re dealing with black, perished sealant on frames and draughts coming in around windows and doors, we can help, whatever the surface.
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.
Whatever the size of the job, you get the same one-year guarantee in Kilmuir and across Highland.

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
The process
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 most of a day for a typical house, less for a few frames from start to finish. Outside jobs in Kilmuir need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Move anything stored near the joints

FAQs for Kilmuir
Is Kilmuir in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Kilmuir is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is window mastic in a coastal place like Kilmuir any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep solvents and bleach off the sealant
- Clear any debris from frame drain holes
- Keep jet washers away from the mastic
- Look round the frames every year or so
Silicone can’t generally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Can I do it myself?
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, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Kilmuir
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Signs it’s time to call us include:
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
- Rain getting in at the frame or under the sill
Whether the job is in Kilmuir itself or nearby, the right material for each joint matters as much as a neat finish.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a place like Kilmuir, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
What window mastic looks like in Kilmuir
Kilmuir 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. Kilmuir 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.
Around Kilmuir, as everywhere, window mastic is only as good as the preparation behind it.
