Window mastic in Newport-on-Tay
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on composite doors, window sills and aluminium frames, and the jobs we see most are water coming in at the bottom corners of a door and black, perished sealant on frames.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Do not use solvent cleaners on the joint
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Do you need window mastic in Newport-on-Tay?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
Managing a site like Newport Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Newport-on-Tay homes and the weather
Newport-on-Tay is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
If you let a flat or house near Dundee station, renewing tired window mastic between tenants heads off draught and damp complaints. Camperdown House, about 5 miles north-west, is one of the historic houses in the wider area around Newport-on-Tay, and older homes nearby need a sealant that suits their walls.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

Newport-on-Tay: your questions answered
Does the coastal weather in Newport-on-Tay affect outside sealant?
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. It’s worth checking the walls that face the sea first.
Will you come out to Newport-on-Tay?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can you seal the gap between the frame and the plaster indoors?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Newport-on-Tay.
Can I paint over the new sealant?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
