Window mastic for homes and businesses in Corkerhill
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on patio & French doors, uPVC windows and aluminium frames, and people most often call us about hard, cracked sealant around windows and draughts coming in around windows and doors.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you are in a tenement flat or a house in Corkerhill, the joint between frame and wall is what keeps the weather out.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Corkerhill, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us about any water getting in
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

Advice
Surface by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We’ll tell you if that is what we find.
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.
Questions from Corkerhill
Who arranges sealant work on the shared parts of a tenement in Corkerhill?
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, and we can quote for the factor or the owners directly.
Can you do window mastic in Corkerhill?
Yes, Corkerhill is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- The type of sealant required
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How much there is to do
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Private landlords in Corkerhill 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.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

When to call us in Corkerhill
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Keep an eye out for these signs:
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
For landlords with property near Corkerhill station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What to look for in a quote
- Which colour the sealant will be
- Are they insured?
- What the cure time is
- What happens if they find a problem under the old sealant
Honest limits
Before you book, it’s worth knowing the limits too:
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Patio & French doors
- Window sills
- uPVC windows
- Aluminium frames
- Composite doors
- Timber windows & doors
Frames and glazing around Corkerhill
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Managing a site like St. Paul's High School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to St James' (Pollok) Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
