Window mastic in Kilkerran
Homes in Kilkerran have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have sealant in the wrong colour for the frame and hard, cracked sealant around windows, we can put it right, on uPVC windows, window sills and composite doors alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job is covered by a 12-month guarantee.

Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Kilkerran homes and the weather
Kilkerran is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Tirfergus House (about 4 miles west) are a reminder that the area around Kilkerran has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Kilkerran Old Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you need window mastic in Kilkerran?
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch after spotting one of these:
- Whistling draughts around closed windows
- A bead that does not match the frame
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
Around Kilkerran, as everywhere, window mastic is only as good as the preparation behind it.

Why act early in Kilkerran
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In an older home around Kilkerran, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Common questions in Kilkerran
Will you come out to Kilkerran?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Kilkerran in your area for window mastic?
Yes, Kilkerran is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Is the new sealant paintable?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
