What affects the quote in Nairn
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- The amount of work
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- Where the property is
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
We quote each job on its own, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details, and photos are welcome.
How we handle sand mastic in Nairn
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on brick reveals, sash and case windows and stone surrounds, and common reasons people get in touch are patchy fillers round a sash window and wind and rain getting in round a sash window.
Scottish weather is hard on window mastic, and a town like Nairn gets its share of wind and rain. The windows facing the weather are normally the first to leak.
All of our work is guaranteed for twelve months.

Why it’s worth doing now in Nairn
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. For landlords in Nairn, damp and leaks can fall under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
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.

Common questions in Nairn
Do you cover Nairn for sand mastic?
Yes. Our work covers the whole of Scotland, and Nairn is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Is sand mastic in a coastal place like Nairn 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.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
How much does sand mastic cost in Nairn?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
How long will you be here?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we will say how long yours will take.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Parking around Nairn is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Related advice
Landlord and commercial work in Nairn
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and agents in Nairn can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Sand mastic in Nairn: local notes
Nairn 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Nairn station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near The High Church and Church Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Nairn Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.
