Window Mastic in Crieff
Our applicators work in Crieff on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Draughty joints inside around the window
How we handle window mastic in Crieff
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include old mastic that has gone black or come away and water coming in at the bottom corners of a door, across uPVC windows, timber windows & doors and patio & French doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes most of a day for a typical house, less for a few frames. Outside jobs in Crieff need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- On commercial sites, let us know about site rules

FAQs for Crieff
Can you do window mastic in Crieff?
Yes, Crieff is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Crieff?

How long should I leave it?

Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Perth and Kinross.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Why act early in Crieff
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In an older home around Crieff, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Do you need window mastic in Crieff?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
People normally contact us after spotting something like this:
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
- Gaps left after new windows were fitted
For an older house near a landmark such as St Michael's Hall, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Clear any debris from frame drain holes
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Crieff homes and the weather
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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Schools such as Morrison's Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
