Window & door mastic in Inver, Highland
Window mastic for Inver and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
Window mastic for homes and businesses in Inver
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Common call-outs are for cracked or shrunken mastic around the frame and white mastic on grey or black frames, across window sills, timber windows & doors and patio & French doors.
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 covered after we’ve gone.

What the job involves on each surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Common problems we fix in Inver
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
It’s worth asking for a quote if you see:
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Draughty joints inside around the window
Around Inver, as everywhere, window mastic is only as good as the preparation behind it.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a morning for a couple of windows and a door, including the tidy-up. For a place like Inver, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
What affects the quote in Inver
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- The old material and how stubborn it is
- How easy the joints are to reach
- The number of rooms or windows
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- The address or postcode of the job
- If someone has resealed it before
- The rough size of the job
- Whether it’s a home or a business
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
Landlord and commercial work in Inver
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Inver homes and the weather
Inver is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Fearn station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- Faulty window hardware
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

Questions from Inver
Is Inver within the area you cover?
Yes, Inver is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Fearn station. Can you help?
Yes, we work for letting agents and landlords. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you match the sealant to my frames?
Normally, yes. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can new window sealant be painted?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
