Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
- Penetrating damp from a failed cavity tray or render

Window mastic for homes and businesses in Balgay
Homes in Balgay have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have sealant in the wrong colour for the frame and leaking joints at the ends of sills, we can help, on window sills, uPVC windows and composite doors alike.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. For a flat in Balgay, access is the first thing to plan.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in Balgay
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A few things move the cost up or down: 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.

How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
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 handful of frames, longer for a whole house and we leave things clean and tidy. Inside a flat in Balgay, 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.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Related advice
Balgay: your questions answered
Is window mastic in a coastal place like Balgay any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
How do repairs to the shared parts of a tenement in Balgay get organised?
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. Windows often belong to the individual flat, but it’s worth checking your deeds.
How many windows can you do in a day?
A few frames take a few hours. We confirm the timing with your quote.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Do you come to Balgay?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Windows and doors in 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 window and door frames, which can dry out and crack sooner where a building faces the weather. Dundee’s older tenements are sandstone, and the city sits on the Firth of Tay.
In the older streets around St Mary's R.C. Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Invergowrie station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Balgay is about 2 miles west of Dundee, in Dundee. We provide window mastic to homes and businesses in Balgay and the surrounding area. Across Dundee, we cover 50 places, Balgay among them.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Common problems we fix in Balgay
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Cold air getting in at the frame edge
Schools such as Menzieshill High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
