Remedial sealant in Glasgow

Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you’re dealing with a shower that leaks however often it’s resealed and sealant peeling off a dusty or damp surface, we can put it right, whatever the surface.

Tenement flats are common in all four of Scotland’s big cities, alongside houses and newer flats. In a tenement, most bathrooms sit above someone else’s ceiling, so failed sealant around a bath or shower can soon become a neighbour’s problem.

Every job is covered by a 12-month guarantee.

What affects the cost of remedial sealant

Call for a quick quote. The main things that affect it are:

  • Whether there’s mould to deal with
  • The number and length of the joints
  • Which sealant suits the joint
  • When we can work, for business premises

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Asking for a quote

To help us quote quickly, please include:

  • Roughly how big the job is
  • Whether it has been sealed before
  • The type of property
  • Any access issues, like height or stairs

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Glasgow questions

Do you work in hotels near Glasgow?

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.

Can a failed shower seal in a tenement flat in Glasgow leak into the flat below?

Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. Cutting out the old sealant and laying a fresh bead puts a stop to it.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

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 what makes the new bead last.

Do you guarantee remedial jobs?

Yes. Our one-year guarantee covers the work, and we’re ARBOMaster approved.

How long does remedial resealing take?

The number of joints and layers decides it. You’ll have a timescale before any work begins.

How much does remedial sealant cost in Glasgow?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • A tray or bath that is cracked
  • Water damage behind tiles that needs a tiler

If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Surfaces we seal

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

Why deal with it now?

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 stripping is where most of our time goes. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What remedial sealant looks like in Glasgow

Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that does not dry out. Glasgow has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.

For landlords with property near Anderston station, a joint that keeps failing is best fixed properly while the property is empty.

Glasgow is in Scotland. Wherever you are in the G33 postcode area, our applicators can take on remedial sealant. Our area takes in 183 places across Glasgow, large and small.

Work in G33, G32, G53 and G46 works the same way as everywhere else we cover. That includes homes and businesses on Plantation Square, Minerva Square and George Square and the roads around them. Glasgow sits on or near the A8 and A74, so getting to you is simple. We also cover the places around Glasgow: Plantation (1 mile west), Tradeston (1 mile east), Kinning Park (1 mile south-west), Sandyford (1 mile north) and Blythswood Hill (1 mile north-east). Within a short drive, we also cover Yoker (5 miles north-west), Hillpark (3 miles south), Temple (3 miles north-west), Merrylee (3 miles south), Muirend (3 miles south) and Newlands (3 miles south).

Around Glasgow

Around Glasgow, our work takes us to homes and buildings near Kelvingrove Park, St Vincent Street Church and Old Toll Bar and the streets around them. Other local landmarks include Stirling's Library (1 mile east), Craigholme School (1.2 miles south-west) and Glasgow Academy (0.7 miles north). Glasgow has its own railway station: Anderston station. A little further out are NHS Louisa Jordan (0.7 miles north-west) and Princes Square (0.8 miles east). For a walk, there’s Hogganfield Loch and Cathkin Braes.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Common problems we fix in Glasgow

Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.

The problems people normally mention when they call include:

  • Gaps opening along the back of the worktop
  • Torn expansion joints
  • Over-sealed joints coming away
  • Mould trapped under a layer of silicone

For site and facilities teams at buildings such as Our Lady and St Margaret's Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Choosing a sealant specialist

The process

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Glasgow, tell us the floor, how the door entry system works and where we can park nearby.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  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

  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
  • Plan for the work area to be out of bounds to pets and children
