Kilmichael Glassary Window Mastic
Window and door frames in Kilmichael Glassary need attention? We cut out the old, prepare the joints and apply the right sealant.
- A bead that does not match the frame
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
Window mastic in Kilmichael Glassary
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on aluminium frames, patio & French doors and timber windows & doors, and common reasons people get in touch are leaking joints at the ends of sills and black, perished sealant on frames.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All of our work is guaranteed for twelve months, in Kilmichael Glassary and everywhere else we cover.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Repaint timber before it’s bare
Most silicone sealants will not take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Frames and glazing around Kilmichael Glassary
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Kilmichael Glassary, as everywhere, window mastic is only as good as the preparation behind it.

What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Access and height
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
- How we’d reach the joints
We quote each job on its own. Just send an email to info@mrmastic.co.uk with the details.
When to call us in Kilmichael Glassary
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
For an older house near a landmark such as Kilmichael Glassary Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

The process
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 anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Kilmichael Glassary depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Tell us about any water getting in

What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Why act early in Kilmichael Glassary
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In an older home around Kilmichael Glassary, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
