Sand mastic in Deaconsbank, done properly
Across Deaconsbank, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Typical jobs include mastic that needs renewing before redecorating and failed mastic on an exposed elevation, across stone surrounds, timber door frames and brick reveals.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Deaconsbank, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the visit works
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair.

- First we agree which joints need doing.
- Old mastic and any loose material are raked out.

- We dress the finish so it sits neatly against the masonry.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Look over the window mastic once a year
- Do not paint over the new mastic
- Make sure water runs off the sill
- Go gently near the mastic when preparing windows
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Signs you need sand mastic in Deaconsbank
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The most common problems we see are:
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
If you look after a building such as Eastwood High School, its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Deaconsbank
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Private landlords in Deaconsbank must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Deaconsbank questions
How is work on the outside of a tenement in Deaconsbank normally arranged?
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.
Do you cover Deaconsbank for sand mastic?
Yes, Deaconsbank is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
