How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
How we handle remedial sealant in Downfield
A joint that keeps letting you down needs more than another bead. Send pictures when you email us at info@mrmastic.co.uk, and say how long ago it was last done. We work on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant, and people most often call us about caulk or the wrong sealant used in a wet area and a shower that leaks however often it’s resealed.
From stone-built tenements to new flats and suburban houses, Downfield is in a city with every kind of home. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in Downfield
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- The old material and how stubborn it is
- The number and length of the joints
- Any working-time requirements on site
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

- The problem you’ve noticed
- How we’d reach the joints
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
FAQs for Downfield
Do you work for landlords with property near Dundee station?
Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
I’m in a tenement in Downfield. Could worn sealant affect the flat downstairs?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. A proper reseal, with all the old sealant cut out, stops it at the source.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Downfield.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
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.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What if resealing will not fix my leak?
In that case, we tell you what we have found. You may need a plumber or bathroom fitter.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Do you need remedial sealant in Downfield?
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
It’s worth asking for a quote if you see:
- Sealant peeling off a dusty or damp surface
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
Schools such as Lawside Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
What to look for in a quote
- The length of the guarantee
- Whether they’re fully insured
- When the joint can take water or movement
- Who turns up on the day
Keeping the joints in good condition
Looking after new joints is easy:
- Keep bleach and abrasives off the bead
- Do not wait for a small gap to become a leak
- Look for stains below bathrooms now and then
- Get the cause of a repeat leak found before resealing
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- A bath, tray or worktop that moves until it’s properly fixed
- Water damage behind tiles that needs a tiler
- Cracks in the fitting rather than the joint
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

- Shrunken worktop sealant

Bathrooms and kitchens in Downfield
Downfield is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Sandstone tenements are a big part of Dundee’s housing, where a failed bath or shower seal can reach the flat below.
Letting a property close to Dundee station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Leave it or put it right?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Wind-driven rain gets into any failed joint on the outside of a city building, and in Downfield, damp can spread through stone and plaster before anyone sees it.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

How it works
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied, and we explain the cure time before we leave. In a city area like Downfield, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
