About our window mastic in Colbost
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before any work starts. To get one, send an email to info@mrmastic.co.uk with the number of frames and any access details for window mastic in Colbost. If you are dealing with black, perished sealant on frames and gaps where the sill meets the wall, we can put it right, on composite doors, window sills and aluminium frames alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Common problems we fix in Colbost
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
It’s worth asking for a quote if you see:
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
For jobs in and around Colbost, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before you book

- How the colour is chosen
- How long to leave it before use

How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

What window mastic looks like in Colbost
Colbost is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Around Colbost, as everywhere, window mastic is only as good as the preparation behind it.

Landlords, agents and businesses in Colbost
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Out of town in Scotland, exposed walls take a lot of weather, 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 a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.

How it works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. For a place like Colbost, 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.
- Deep gaps are filled with backing rod to set the depth.
- 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 sign-in or site rules at work premises

Advice
Common questions in Colbost
Does living near the coast affect window mastic in Colbost?
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. Walls facing the sea are normally the first to need attention.
Do you cover Colbost for window mastic?
Yes, Colbost is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
How long does it take to reseal the windows on a house?
A few frames take a few hours. You’ll get a timescale with the quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
