Sand mastic for sash & case windows in Wick, Highland
We cover Wick for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Failed mastic on an exposed elevation
- Draughty sash windows at the surround
- Mastic dropping out of the joint
Sand mastic in Wick
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on timber door frames, sash and case windows and stone surrounds, and common reasons people get in touch are cracked mastic round a front door frame and window mastic to renew ahead of painting.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Looking after it afterwards
After the cure time, these simple habits help:
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What else we do in Wick
Why act early in Wick
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. In an older home around Wick, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

- An ARBOMaster approved applicator
Sand mastic in Wick: local notes
Wick 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.
For landlords with property near Wick station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Wick questions
Do you work for landlords with property near Wick station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Will you come out to Wick?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will talk you through it.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Landlord and commercial work in Wick
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Landlords and agents in Wick can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Signs you need sand mastic in Wick
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
If you look after a building such as Wick High School, larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
