Sand mastic in Melvich, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, on sash and case windows, tenement windows and brick reveals.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work comes with a one-year guarantee.

What affects the cost of sand mastic
There’s no set price list, because no two jobs are the same. What we look at:
- How many rooms, windows or areas are involved
- The type of sealant required
- Access and height
- The amount of work
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Pictures of the joints, sent by email
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.
Aftercare tips
A little care helps the new joints last. We recommend:
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Have rotten timber repaired before new mastic goes in
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Melvich homes and the weather
Melvich 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Melvich, as everywhere, sand mastic is only as good as the preparation behind it. For jobs in and around Melvich, choosing the right material for each joint is as important as a tidy finish.
Melvich (Gaelic: Meabhaich) is about 15 miles west of Thurso, in Highland. Whether you’re in the middle of Melvich or further out, sand mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Melvich is one of 253 places in Highland where we work.
Work in KW14 is quoted and booked the same way as anywhere else. Whether your property is on Melvich Terrace and Pentland Terrace or anywhere close by, we can help. Close by, we work in Portskerra (1 mile north-west), Strathy (3 miles west), Reay (5 miles east), Forss (11 miles east) and Am Blàran Odhar (11 miles west). If you’re somewhere remote, a little more planning is needed.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Decayed frames that need repair
- Whether work needs listed building consent
- Putty and glazing repairs
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Where we work in Melvich
- Brick reveals
- Tenement windows
- Stone surrounds
- Timber door frames
- Sash and case windows
- Period & listed homes
Why deal with it now?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
