What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. For a job in Inverness, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints

Sand mastic in Inverness, done properly
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We are often asked to deal with weathered mastic on the most exposed windows and cracked mastic round a front door frame, on brick reveals, sash and case windows and stone surrounds.
Harled walls are common in Scottish towns like Inverness, and sealing a frame against rough harling takes a sealant that grips and moves. A bead that sits on top of the harling rather than in the joint soon lets water in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Inverness homes and the weather
Inverness is close to 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 older windows and doors, especially on the side facing the sea. Inverness is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
If you let a flat or house near Inverness station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Questions from Inverness
Is sand mastic in a coastal place like Inverness any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover Inverness for sand mastic?
Yes. We work across all of Scotland, and Inverness is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll tell you how long to expect.
How much does sand mastic cost in Inverness?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will talk you through it.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

When to call us in Inverness
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we’re asked about most:
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Open joints round the window box
- Old cement repairs round a window that have failed
For site and facilities teams at buildings such as Inverness High School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- What the quote includes, VAT included or not
- What happens if they find a problem under the old sealant
