Windows and doors in Murkle
Murkle is close to 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 failed outside joints work against that.
Letting a property close to Thurso station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we handle sand mastic in Murkle
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on tenement windows, stone surrounds and period & listed homes, and people most often call us about patchy fillers round a sash window and modern sealant on a period surround.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job comes with our one-year guarantee, wherever you are in Highland.

Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.

Aftercare tips
A little care helps the new joints last. We recommend:
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Look over the window mastic once a year
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the quote in Murkle
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The product the joint needs
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
What we need to know
When you call or email, these details help:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- The address or postcode of the job
- The problem you’ve noticed

What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll talk you through it.
What guarantee comes with the work?
All our work has a 12-month guarantee, and we’re fully insured.

Questions to ask before you book
- How hidden problems are handled
- How the colour is chosen
- Whether the sealant suits the joint
- How much experience the applicator has
What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. Outside jobs in Murkle need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
