Window & door mastic in Roughmussel, Glasgow
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Roughmussel. Fully insured, ARBOMaster approved and guaranteed for a year.
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Untidy mastic left by window fitters
Why it’s worth doing now in Roughmussel
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Roughmussel, damp can travel a long way before it shows.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Why book with us
- Old sealant always removed completely
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- A sealant colour to suit the surroundings

How we handle window mastic in Roughmussel
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have sealant in the wrong colour for the frame and mastic that has split away from the wall, we can put it right, on composite doors, timber windows & doors and window sills alike.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. In Roughmussel, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
There’s a 12-month guarantee on every job, whatever its size.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Composite doors
Front doors take the weather head on. Those corners get the most care.
What happens on the day
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. Inside a flat in Roughmussel, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

- Draughts through the window seals rather than the frame
- Faulty window hardware

What window mastic looks like in Roughmussel
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Letting a property close to Nitshill station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Common questions in Roughmussel
How do repairs to the shared parts of a tenement in Roughmussel get organised?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Do you work for landlords with property near Nitshill station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

When to call us in Roughmussel
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us include:
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
- Leaking joints at the ends of sills
- Gaps left after new windows were fitted
If you look after a building such as St. Paul's High School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- What the quote includes, VAT included or not
- What guarantee comes with the work
- Whether they seal over old material or remove it
- How the colour is chosen
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep paint off silicone joints
- Wash the frames with mild soapy water
- Don’t aim a pressure washer at the joints
- Avoid harsh chemicals near the mastic
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
