Window mastic in Dinnet, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with water coming in at the bottom corners of a door and white mastic on grey or black frames, on aluminium frames, composite doors and patio & French doors.
Mastic can only go onto a dry joint, so outside work in Dinnet depends on the weather. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
What sealant work cannot fix
Before you book, it’s worth knowing the limits too:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- Broken hinges, locks or handles
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What window mastic looks like in Dinnet
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Dinnet, as anywhere, good window mastic starts with a clean, dry, properly prepared joint. Homes close to Dinnet Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Your questions about window mastic in Dinnet
Is there a guarantee on window mastic in Dinnet?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Dinnet for window mastic?
Yes. Our work covers the whole of Scotland, and Dinnet is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do you have sealant for grey or black windows?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I paint over the new sealant?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How do I get a quote for window mastic in Dinnet?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Dinnet, 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
