How we handle window mastic in Sound
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before we start. Just email us at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. If you’re dealing with untidy mastic left by window fitters and gaps between the frame and the inside reveal, we can put it right, whatever the surface.
In and around a place like Sound, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Patio & French doors
- uPVC windows
- Composite doors
- Timber windows & doors
- Aluminium frames
- Window sills
Different surfaces, different methods
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What window mastic looks like in Sound
Sound 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Anderson High School, the mastic around its windows and doors needs looking after like any other building’s. Around Sound, as everywhere, window mastic is only as good as the preparation behind it.
Sound is about 1 mile south-west of Lerwick, in the Shetland Islands. Across the ZE1 area, our applicators can take on window mastic. Our area takes in 63 places across the Shetland Islands.
All of ZE1 is within our area for window mastic, from the main roads to the quietest streets. That includes homes and businesses on Quoys Road, South Road and Oversund Road and the roads around them.

The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. For a place like Sound, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Advice
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In an older home around Sound, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
