About our window mastic in Glencarse
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include gaps where the sill meets the wall and mastic that has split away from the wall, across composite doors, uPVC windows and aluminium 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.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What else we do in Glencarse
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a morning for a couple of windows and a door. For a place like Glencarse, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

Related advice
What window mastic looks like in Glencarse
Glencarse is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In and around Glencarse, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
- Wipe condensation off the frames
- Keep paint and stain on wooden frames in good order
Silicone cannot generally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Common questions in Glencarse
Do you cover smaller places like Glencarse?
Yes, Glencarse is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Glencarse for window mastic?
Yes. We work across all of Scotland, and Glencarse is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- How many rooms, windows or areas are involved
- Whether the work is at height
- Any mould that needs treating
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- The address or postcode of the job
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear price.
When to call us in Glencarse
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Look out for these signs:
- Draughty joints inside around the window
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
If you live in an older home near All Saints Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What happens if the job turns out different
- What product goes in the joint
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll send you a clear quote for the lot.
