Window mastic in Sandwick, done properly
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you’re dealing with cracked sealant at the sill ends and cold air getting in at the frame edge, we can help, on aluminium frames, uPVC windows and timber windows & doors 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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sandwick and across the Shetland Islands.

What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. Around Sandwick, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access

What the job involves on each surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Sandwick questions
Do you cover Sandwick for window mastic?
Yes, Sandwick 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, and we will send you a clear quote.
Is Sandwick within the area you cover?
Yes, Sandwick is covered. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Windows and doors in Sandwick
Sandwick 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. On the islands, wind and salt spray are hard on outside sealant.
Around Sandwick, as everywhere, window mastic is only as good as the preparation behind it. Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
