Remedial sealant in Charleston, done properly
Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. We are often asked to deal with kitchen joints letting water behind the worktop and floor or wall movement joints that have failed, on shrunken worktop sealant, leaking tray & enclosure joints and botched or over-sealed joints.
Tenement flats are common in all four of Scotland’s big cities, alongside houses and newer flats. With flats above and below, a leak from a tired seal can reach the flat underneath, and that is as true in Charleston as anywhere in the city.
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.

Common questions in Charleston
Do you take on hotel work around Charleston?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I’m in a tenement in Charleston. Could worn sealant affect the flat downstairs?
Yes, and the first sign is often a mark on the ceiling below. A proper reseal, with all the old sealant cut out, stops it at the source.
Can you remove old sealant without damaging the bath?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Failed tanking or loose tiles behind the sealant
- Plumbing leaks behind walls or under trays
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.

Why act early in Charleston
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. For landlords in Charleston, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What you get with us
- Arbo and Everbuild products
- Colour agreed with you before work begins
- ARBOMaster approved applicator
- Over 20 years’ experience
Looking after it afterwards
So the new joints stay in good condition:
- Get the cause of a repeat leak found before resealing
- Keep the room well ventilated
- Deal with small splits early
- Keep bleach and abrasives off the bead
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
Charleston homes and their sealant
Charleston is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Sandstone tenements are a big part of Dundee’s housing, so a leaking seal can soon reach the neighbours below.
Homes close to Lochee Baptist Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Invergowrie station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Menzieshill High School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Charleston is about 2 miles west of Dundee, in Dundee. Jobs in Charleston get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our Dundee coverage runs to 50 places, and Charleston is one of them.
Here we cover the DD2 postcode area for remedial sealant. That includes homes and businesses on Liff Road, South Road and Dunholm Road. We also cover Menzieshill (1 mile south), Dryburgh (1 mile north-east), Ninewells (1 mile south), Gowrie Park (1 mile south-west) and Camperdown (1 mile north).

The nearest railway station is Invergowrie station, about 1.4 miles south-west. Well-known places in the area include Overgate Centre (2.6 miles east) and Dudhope Castle (2.1 miles east).

How the job changes by surface
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Charleston, it helps to know the floor, the door entry arrangements and the nearest parking.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
