About our sand mastic in Lonemore
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you’re dealing with patchy fillers round a sash window and mastic round period door frames that has failed, we can help, whatever the surface.
In and around a place like Lonemore, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Each job carries a 12-month guarantee, whatever its size.

Sand mastic in Lonemore: local notes
Lonemore 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 older windows and doors, 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.
In and around Lonemore, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What affects the cost of sand mastic
Call for a quick quote. What matters most is:
- The type of sealant required
- How many rooms, windows or areas are involved
- Access and height
- Any mould that needs treating
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
When you call or email, it’s useful to know:
- If someone has resealed it before
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Honest limits
Before you book, it’s worth knowing the limits:
- Sashes that rattle, stick or will not open
- Decisions on consent for listed homes
- Decayed frames that need repair
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

Your questions about sand mastic in Lonemore
Do you cover smaller places like Lonemore?
Yes, Lonemore is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Lonemore any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
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.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you guarantee sand mastic work?
Every job comes with our 12-month guarantee, and we’re fully insured.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t paint over the new mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What we are called out for in Lonemore
Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.
Most people get in touch after spotting something like this:
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
For site and facilities teams at buildings such as Gairloch High School, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Lonemore
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve 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. Outside jobs in Lonemore need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Mention any parking rules near the property
