About our sand mastic in Longman
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on timber door frames, sash and case windows and tenement windows, and common reasons people get in touch are wind and rain getting in round a sash window and gaps round a timber door in stone or brick.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Every job is covered by our one-year guarantee, wherever you are in Highland.

FAQs for Longman
Does living near the coast affect sand mastic in Longman?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I let a flat near Inverness station. Can you help?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Where are you based?
We work from Crawley. Our applicators cover Longman, along with the rest of our area.
Do you cover Longman?
Yes. We work in Longman, as part of our work across South East England, London and Scotland. To book, drop us a line at info@mrmastic.co.uk.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
Can you replace silicone on a period window with sand mastic?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
Do you need sand mastic in Longman?
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.
Look out for these signs:
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
If you let a flat or house near Inverness station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Windows and doors in Longman
Longman 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. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as East Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Millburn Academy, larger buildings have plenty of frames, and the mastic around each one ages.
Longman is about 1 mile north of Inverness, in Highland. We carry out sand mastic for homeowners, landlords and businesses in Longman, as part of our work across Highland. Longman is one of 253 places in Highland where we work.

What’s near Longman

Well-known places in the area include Inverness Castle (0.8 miles south) and Royal Northern Infirmary (1.3 miles south). For a walk, there’s Tomnahurich.
Keeping the joints in good condition
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Clear gutters so water does not pour onto the windows
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a single window, longer for several. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Related advice
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
