Sand mastic in Lochinver, done properly
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include silicone on a period window that looks wrong and old cement repairs round a window that have failed, across brick reveals, sash and case windows and timber door frames.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need sand mastic in Lochinver?
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they generally need raking out.
Signs it’s time to call us include:
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
- Open joints round the window box
- Wind and rain getting in round a sash window
For jobs in and around Lochinver, choosing the right material for each joint is as important as a tidy finish.

Sand mastic in Lochinver: local notes
Lochinver is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Lochinver 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.
Around Lochinver, as everywhere, sand mastic is only as good as the preparation behind it.

FAQs for Lochinver
Is sand mastic in a coastal place like Lochinver 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.
Is Lochinver within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before any work starts.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Get any rot dealt with first
- Check the mastic when you check the paintwork
- Leave the new mastic unpainted
- Make sure water runs off the sill
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
