Window mastic in Evanton
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include sealant in the wrong colour for the frame and gaps left after new windows were fitted, on uPVC windows, patio & French doors and composite doors.
Mastic can only go onto a dry joint, so outside work in Evanton depends on the weather. Let us know about access to every frame, including any upstairs.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Frames and glazing around Evanton
Evanton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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 Alness station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Evanton (Gaelic: Baile-Eoghain) is about 14 miles north of Inverness, in Highland. From the centre of Evanton to the outskirts, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Evanton is one of 253 towns and villages in Highland we cover.
Postcode districts we cover here for window mastic: IV16. That includes homes and businesses on Station Road, Camden Street and Balconie Street and the roads around them. Other places close to Evanton include Cullicudden (3 miles south-east), Alness (4 miles north-east), Dalmore (4 miles north-east), Culbokie (4 miles south) and Dingwall (5 miles south-west). Within a short drive, we also cover Inverness (14 miles south), Cradlehall (15 miles south-east), Tain (14 miles north-east), Merkinch (13 miles south), Hilton (15 miles south) and Crown (14 miles south).

What’s near Evanton

Why act early in Evanton
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. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Why book with us
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows

- Anti-fungal sanitary silicone in wet areas

Evanton questions
Is window mastic in a coastal place like Evanton any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Evanton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Evanton and the rest of Highland, along with the rest of our area.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Can you match the sealant to my frames?
Generally, yes. Tell us the frame colour when you get in touch and we’ll use the nearest match.
Should I try DIY first?
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.
Honest limits
It helps to know what we cannot do too:
- Soft or decayed wood in the frame
- Penetrating damp from a failed cavity tray or render
- A sash or casement that will not close properly
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clear any debris from frame drain holes
- Repaint timber before it’s bare
- Don’t paint over the silicone
- Do not use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house.

- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.

Signs you need window mastic in Evanton
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
Most people get in touch when they notice one of these:
- Mastic that has split away from the wall
- A bead that does not match the frame
- Mastic that’s falling out in pieces
- Rain getting in at the frame or under the sill
Historic houses such as Novar House, about 1.2 miles north, show how far back building around Evanton goes.
