Window & door mastic in Kilmuir, Highland
Problem with your window and door frames in Kilmuir? We cut out the old, prepare the joints and apply the right sealant.
- Cracked or shrunken mastic around the frame
- Mastic that is falling out in pieces
- Untidy mastic left by window fitters
What happens if it’s left?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Why Kilmuir customers choose us
- Sanitary silicone with an anti-fungal additive in wet areas
- Old sealant always removed completely
- Approved under the ARBOMaster scheme

What we do, step by step
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 a few hours for a few frames, or a day or more for a whole house. For a place like Kilmuir, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any tricky access
- Tell us about any water getting in
- Clear items away from the joints we are working on

If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on

- Timber windows & doors
- Composite doors
- Window sills

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What else we do in Kilmuir
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What window mastic looks like in Kilmuir
Kilmuir 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. 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.
For an older house near a landmark such as Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Invergordon station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Questions from Kilmuir
I let a flat near Invergordon station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is Kilmuir within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
How much does window mastic cost in Kilmuir?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
What affects the quote in Kilmuir
We don’t publish a price list, because no two jobs are the same. What we look at:
- The amount of work
- The number of rooms or windows
- Whether the work is at height
- Which sealant suits the joint
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
What to tell us for a quote
When you contact us, these details help:
- A few photos by email, if you can
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
