Why it’s worth doing now in Ninewells

Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. For landlords in Ninewells, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Remedial sealant for homes and businesses in Ninewells

If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. Finding that cause comes before any new sealant. We work on mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints, and people most often call us about black mould underneath the bead and decorators’ caulk around a bath or shower.

Ninewells is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Rooms like that are often small and slow to dry out, and steam with nowhere to go is what turns sealant black and grout grey.

The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Quotes for remedial sealant in Ninewells

Every job gets its own quote. This is what makes a difference:

  • The number and length of the joints
  • How many areas need sealing
  • Whether the work is at height
  • Whether there’s mould to deal with

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What we need to know

Photos by email are helpful but not essential. Try to tell us:

  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business

For remedial sealant in Ninewells, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

How the visit works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. In a city area like Ninewells, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.

  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. Mould is treated and the joint dried.
  4. The right product goes in, with backing where the joint moves.
  5. We finish neatly and point out anything that needs another trade.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
  • Plan for the work area to be out of bounds to pets and children

Questions from Ninewells

Do you work in hotels near Ninewells?

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

Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.

Where are you based?

We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do you offer different sealant colours?

In most cases you can choose. We will explain which colours are available and agree one before we start.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

My shower still leaks after a reseal. Can you sort it?

Yes, generally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

How to look after the new joints

After the cure time, these simple habits help:

  • Check trays and worktops don’t move
  • Get the cause of a repeat leak found before resealing
  • Keep bleach and abrasives off the bead
  • Do not add new sealant on top of old

If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.

Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.

What the job involves on each surface

Over-sealed & botched joints

Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.

Worktops & kitchens

Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.
