How we handle external mastic in Newport-on-Tay
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you have weathered mastic that no longer stretches and cracked joints where brick meets render or frames, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Newport-on-Tay depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You get a one-year guarantee, the same in Newport-on-Tay as everywhere else we work.

Signs you need external mastic in Newport-on-Tay
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
These are the problems we are asked about most:
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
If you let a flat or house near Dundee station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Newport-on-Tay buildings and the weather
Newport-on-Tay 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Newport Primary School, its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Camperdown House, about 5 miles north-west, show how far back building around Newport-on-Tay goes, and older homes nearby need a sealant that suits their walls.
Newport-on-Tay is about 3 miles south-east of Dundee, in Fife. Newport-on-Tay gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Across Fife, we cover 133 places, Newport-on-Tay among them.
Work in DD6 is quoted and booked the same way as anywhere else. Local streets include High Street, Woodmuir Terrace and Woodmuir Crescent.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Newport-on-Tay need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Honest limits
Sealant isn’t the answer to every problem, and we will tell you before any work starts. It won’t solve:
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Newport-on-Tay questions
I let a flat near Dundee station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Will you come out to Newport-on-Tay?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you work at height?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Where do you work from?
We work from Crawley. We cover Newport-on-Tay and the rest of Fife, along with the rest of our area.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Aftercare tips
To keep the joints looking good and working properly:
- Make sure movement joints are not pointed over
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
