Windows and doors in Levenwick
Levenwick 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. 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.
In and around Levenwick, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How we handle window mastic in Levenwick
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on window sills, uPVC windows and composite doors, and people most often call us about cold air getting in at the frame edge and gaps left after new windows were fitted.
Mastic can only go onto a dry joint, so outside work in Levenwick depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. 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.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Signs you need window mastic in Levenwick
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
Whether the job is in Levenwick itself or nearby, the right material for each joint matters as much as a neat finish.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, 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.
What affects the cost of window mastic
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The number of rooms or windows
- Mould in or behind the old joints
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

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 job generally takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
Getting a quote
Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.
