About our window mastic in Castledykes
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We are often asked to deal with gaps between the frame and the inside reveal and mastic that’s falling out in pieces, on composite doors, timber windows & doors and window sills.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
There’s a 12-month guarantee on every job.

Castledykes: your questions answered

Is Castledykes in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Castledykes is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Does the work come with a guarantee?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
How much does window mastic cost in Castledykes?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Why act early in Castledykes
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Castledykes, 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.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.

Window mastic in Castledykes: local notes
Many older homes in Scotland have sash and case windows, 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.
If you live in an older home near Troqueer Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Dumfries station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots are not blocked
- Walk round the house once a year and look at the joints
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
Most silicone sealants won’t take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Different surfaces, different methods
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Signs you need window mastic in Castledykes
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
People normally contact us when they notice something like this:
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Rushed sealant from a window installation
Schools such as Dumfries Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Castledykes may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
