Remedial sealant near Dundee

Looking after it afterwards

So the new joints stay in good condition:

  • Have loose fittings fixed before resealing
  • Never seal over old silicone
  • Use a soft cloth, not a scourer, on silicone
  • Look for stains below bathrooms now and then

Keep an eye on the joint at first, especially if movement was the problem. Should anything change, drop us a line at info@mrmastic.co.uk.

If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.

About our remedial sealant in Dundee

If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. If you are dealing with decorators’ caulk around a bath or shower and sealant applied over old sealant that has lifted, we can help.

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’s as true in Dundee as anywhere in the city.

Every job is covered by our 12-month guarantee.

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours, depending on how many layers have to come out. Parking in city streets around Dundee can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. We finish neatly and point out anything that needs another trade.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts
  • Let us know if you’ve seen damp or leaks

Advice

Why deal with it now?

A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. If they’re not, we will tell you. Wind-driven rain gets into any failed joint on the outside of a city building, and in Dundee, damp can spread through stone and plaster before anyone sees it.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Why us?

  • A 12-month guarantee on all work
  • More than 20 years in sealant work

Surface by surface

Worktops & kitchens

Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed in a colour to suit.

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Remedial sealant around Dundee

Dundee is within about 2 miles of 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. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.

If you look after a building such as Scottish School of Contemporary Dance, we reseal washrooms and kitchens in schools and businesses as well as homes.

What sealant work can’t fix

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Sealant in an older building that needs testing for asbestos first
  • A bath, tray or worktop that moves until it’s properly fixed
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Surfaces we seal

  • Shrunken worktop sealant
  • Botched or over-sealed joints
  • Failed movement joints
  • Leaking tray & enclosure joints
  • Expansion joints
  • Mouldy bath & shower sealant

Your questions about remedial sealant in Dundee

Can you help a landlord with a rental near Dundee station?

Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.

Could a leaking bath seal in my Dundee flat reach the neighbours below?

Yes, and the first sign is often a mark on the ceiling below. Cutting out the old sealant and laying a fresh bead puts a stop to it.

Will there be a smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Do you guarantee remedial jobs?

Yes, with our 12-month guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Can you strip sealant from an acrylic tray safely?

Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that’s already there.

How long does remedial resealing take?

Allow a few hours for a typical bath or shower, longer where several layers have been applied. You’ll know the timing when we quote.

What we are called out for in Dundee

Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.

People normally contact us after spotting one of these:

  • Sealant that came away because the surface wasn’t prepared
  • Gaps opening along the back of the worktop
  • Floor or wall movement joints that have failed
  • Repeat leaks from the same joint

Rented homes near Dundee station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
