What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Mansewood, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Advice
How we handle window mastic in Mansewood
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with mastic that has split away from the wall and gaps left after new windows were fitted, across timber windows & doors, uPVC windows and composite doors.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
All our work is covered by our one-year guarantee, wherever you are in Glasgow.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- The type of sealant required
- Whether the work is at height
- Whether old sealant or filler has to be cut out
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What we need to know
When you call or email, these details help:
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Photos by email, if that is easy
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Windows and doors in Mansewood
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows generally belong to the flat, but the title deeds have the final say. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For landlords with property near Pollokshaws West 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 Hillpark Secondary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Pollokshaws Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Air rooms to keep condensation down around windows
- Keep timber frames painted
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
