Window mastic in Tobermory, done properly
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for mastic that has split away from the wall and sealant in the wrong colour for the frame, on timber windows & doors, uPVC windows and patio & French doors.
Mastic can only go onto a dry joint, so outside work in Tobermory depends on the weather. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a 12-month guarantee.

Signs you need window mastic in Tobermory
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That’s what backing rod is for.
Common reasons people contact us are:
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
Schools such as Tobermory High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

The process
There’s no need to move everything out before we come, 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 for a typical job. Somewhere like Tobermory may be a longer drive, and the journey is planned ahead. 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
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Use gentle cleaners on frames and sealant
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
- Check the mastic once a year
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Tobermory questions
Does living near the coast affect window mastic in Tobermory?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you do window mastic in Tobermory?
Yes. Our work covers the whole of Scotland, and Tobermory is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before work begins.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Leave it or put it right?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a place like Tobermory, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Windows and doors in Tobermory
Tobermory is close to 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. Tobermory 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, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
