About our sand mastic in Balgay
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. If you have failed mastic on an exposed elevation and old cement repairs round a window that have failed, we can put it right.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Every job comes with a 12-month guarantee, wherever you are in Dundee.

Signs you need sand mastic in Balgay
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Patchy fillers round a sash window
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
Schools such as Menzieshill High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- What guarantee comes with the work
- Whether VAT is included
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Frames and glazing around Balgay
Balgay is within about 1 mile of 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.
If you let a flat or house near Invergowrie station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Mary's R.C. Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Balgay: your questions answered
I let a flat near Invergowrie station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Who arranges sealant work on the shared parts of a tenement in Balgay?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.
Which is right for my windows, sand mastic or modern sealant?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What the job involves on each surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Leave it or put it right?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Wind-driven rain gets into any failed joint on the outside of a city building, and in Balgay, damp can spread through stone and plaster before anyone sees it.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
