About our sand mastic in Cults
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you are dealing with draughts and rain around sash boxes and silicone on a period window that looks wrong, we can help.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Cults, and in a tenement the outside of the building may be a shared repair.
There’s a 12-month guarantee on every job.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal

- Period & listed homes
- Tenement windows

Why it’s worth doing now in Cults
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. For landlords in Cults, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.
What you get with us
- Anti-fungal sanitary silicone in wet areas

- Fully insured
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Do you need sand mastic in Cults?
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
These are the problems we’re asked about most:
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
- Old cement repairs round a window that have failed
- Silicone on a period window that looks wrong
Rented homes near Aberdeen station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours per window, depending on the condition of the joints. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Cults, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
Before we arrive

Advice
Cults: your questions answered
How is work on the outside of a tenement in Cults usually arranged?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.
Can you do sand mastic in Cults?
Yes. Our work covers the whole of Scotland, and Cults is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later and we will give you an idea for your job.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Cults.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will advise.
What the job involves on each surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
What sand mastic looks like in Cults
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Friendville (about 1.9 miles north-east) nearby, there’s older building stock in the area around Cults as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Historic houses such as Friendville, about 1.9 miles north-east, show how far back building around Cults goes. If you look after a building such as Cults Academy, its window and door frames need their mastic kept sound, just like a home’s.
