Window & door mastic in Kirriemuir, Angus
Window mastic in Kirriemuir from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Water coming in at the bottom corners of a door
What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
Window mastic in Kirriemuir, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on patio & French doors, timber windows & doors and composite doors, and common reasons people get in touch are draughts coming in around windows and doors and white mastic on grey or black frames.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in Kirriemuir and across Angus.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Why act early in Kirriemuir
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. 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.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
Why choose Mr Mastic in Kirriemuir
- White, clear, grey or coloured to suit, where the product allows
- An ARBOMaster approved applicator
- We agree the colour with you first
- Any old sealant cut out fully, not covered over

What else we do in Kirriemuir
What happens on the day
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Kirriemuir 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.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Mention if the joints have been sealed before

Signs you need window mastic in Kirriemuir
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
People generally contact us when they notice something like this:
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
Historic houses such as Glamis Castle, about 3.8 miles south, show how far back building around Kirriemuir goes.

Your questions about window mastic in Kirriemuir
Can you do window mastic in Kirriemuir?
Yes, Kirriemuir is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Is there a guarantee on window mastic in Kirriemuir?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Windows and doors in Kirriemuir
Historic houses like Glamis Castle (about 3.8 miles south) are a reminder that the area around Kirriemuir has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

When it is not the sealant

- A failed sealed unit that has misted up
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Timber windows & doors
- Window sills
- Aluminium frames
- uPVC windows
- Patio & French doors

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
