Window mastic in Caputh, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. If you are dealing with leaking joints at the ends of sills and untidy mastic left by window fitters, we can help, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What sealant work cannot fix
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Broken hinges, locks or handles
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Signs you need window mastic in Caputh
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Whistling draughts around closed windows
For an older house near a landmark such as Caputh Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Which colour the sealant will be
- How much experience the applicator has
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing

What window mastic looks like in Caputh
Sash and case windows are common in older Scottish homes, often pointed into the wall with 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.
Rented homes near Dunkeld & Birnam station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Caputh questions
I let a flat near Dunkeld & Birnam station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Caputh?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you work on first-floor windows?
Normally, yes. We plan safe access before the job, so mention the height and anything in the way.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long will my window job take?
A few frames take a few hours. You will get a timescale with the quote.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Caputh, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.

Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
