Why act early in Firrhill
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Firrhill, damp can travel a long way before it shows.

How we handle sand mastic in Firrhill
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on period & listed homes, timber door frames and stone surrounds, and the jobs we see most are gaps between timber frames and stone or brick and a silicone bead on a sash window that spoils the look.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Firrhill, access is the first thing to plan.
Each job carries a 12-month guarantee.

Frames and glazing around Firrhill
The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls. 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.
For an older house near a landmark such as St Johns Colinton Mains Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Firrhill High School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Slateford station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours per window, depending on the condition of the joints. Inside a flat in Firrhill, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- 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 finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Whether work needs listed building consent
- Sashes that need overhauling
- Cracked or broken glass
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Timber door frames

- Period & listed homes

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 getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Firrhill: your questions answered
How do repairs to the shared parts of a tenement in Firrhill get organised?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is Firrhill in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Firrhill is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
How much does sand mastic cost in Firrhill?
Size, access and the old material all affect the cost. Ask us for a quote.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Landlords, agents and businesses in Firrhill
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.

Your quote is based on your job. We take into account:
