Window Mastic in Kentallen
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Kentallen. Fully insured, ARBOMaster approved and guaranteed for a year.

- Gaps between the frame and the inside reveal
Window mastic in Kentallen
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, window sills and patio & French doors, and common reasons people get in touch are cold air getting in at the frame edge and leaking joints at the ends of sills.
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.
All of our work is guaranteed for twelve months.

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
How it works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Kentallen may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Related advice
Aftercare tips
Good habits help new joints last longer. A few tips:
- Don’t paint over the silicone
- Keep jet washers away from the mastic
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What sealant work cannot fix
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Your questions about window mastic in Kentallen
Do you cover Kentallen for window mastic?
Yes. We work across all of Scotland, and Kentallen is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Will you come out to Kentallen?
Yes, Kentallen is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Is the work guaranteed?
Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What window mastic looks like in Kentallen
Kentallen is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Kentallen is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Whether the job is in Kentallen itself or nearby, the right material for each joint matters as much as a neat finish. In and around Kentallen, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Kentallen
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a place like Kentallen, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
