Your questions about sand mastic in Fraserburgh
Can you do sand mastic in Fraserburgh?

Is there a guarantee on sand mastic in Fraserburgh?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
About our sand mastic in Fraserburgh
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you’re dealing with crumbling sand mastic round a window and patchy fillers round a sash window, we can put it right, whatever the surface.
In a town like Fraserburgh, plenty of homes have harled (roughcast) walls, and the joint between a frame and rough harling needs a sealant that can grip and flex. A bead that sits on top of the harling rather than in the joint soon lets water in.
A one-year guarantee comes as standard.

What you pay reflects the work, not guesswork. That’s why we ask about the job first.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Parking around Fraserburgh is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.

Sand mastic in Fraserburgh: local notes
Fraserburgh 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Fraserburgh, as everywhere, sand mastic is only as good as the preparation behind it. If you look after a building such as Fraserburgh Academy, its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Why it’s worth doing now in Fraserburgh
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Scottish weather finds any gap, and in a town like Fraserburgh, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
- Leave the new mastic unpainted
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Whether work needs listed building consent
- Cracked or broken glass
- Damaged stone surrounds
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
