What window mastic looks like in Linthouse
With historic houses such as Tenement House (about 2.4 miles east) nearby, there’s older building stock in the area around Linthouse as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Linthouse Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Cardonald station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Govan High School, the mastic around its windows and doors needs looking after like any other building’s.

Window mastic in Linthouse, done properly
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you’re dealing with white mastic on grey or black frames and cracked or shrunken mastic around the frame, we can help, on uPVC windows, timber windows & doors and patio & French doors alike.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Linthouse, and in a tenement the outside of the building may be a shared repair.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Your questions about window mastic in Linthouse
Can you help a landlord with a rental near Cardonald station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Linthouse for window mastic?
Yes, Linthouse is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
What we cannot put right
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Patio & French doors
- Composite doors

What the job involves on each surface
Composite doors
Front doors take the weather head on. We pay most attention there.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.

Related advice
Why it’s worth doing now in Linthouse
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Linthouse, damp can travel a long way before it shows.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why Linthouse customers choose us
- Full insurance on every job
- Colour agreed with you before work begins

- Arbo and Everbuild products

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What affects the cost of window mastic
We don’t publish a price list. The quote depends on:
- How much there is to do
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- Whether it has been sealed before
- Where the property is
- How many joints, rooms or windows are involved
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
