Window mastic in Creag Ghoraidh, done properly
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have gaps left after new windows were fitted and sealant in the wrong colour for the frame, we can help, on uPVC windows, window sills and patio & French doors alike.
Mastic can only go onto a dry joint, so outside work in Creag Ghoraidh depends on the weather. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job, whatever its size.

Your questions about window mastic in Creag Ghoraidh
Is Creag Ghoraidh in your area for window mastic?
Yes. We work across all of Scotland, and Creag Ghoraidh is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is window mastic in a coastal place like Creag Ghoraidh any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.

What window mastic looks like in Creag Ghoraidh
Creag Ghoraidh 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. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In and around Creag Ghoraidh, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work normally takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Creag Ghoraidh depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check each frame and agree which ones need doing.
- 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.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Why deal with it now?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. In a place like Creag Ghoraidh, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.
What you get with us
- Anti-fungal silicone where joints get wet
- Tidy, careful work
- Arbo and Everbuild products
- Colour agreed with you before any work starts
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
- Broken hinges, locks or handles
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
What we seal
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors
- Timber windows & doors
- uPVC windows
Common problems we fix in Creag Ghoraidh
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Common reasons people contact us include:
- A bead that doesn’t match the frame
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
Whether the job is in Creag Ghoraidh itself or nearby, the right material for each joint matters as much as a neat finish.
