Remedial sealant in St George's Fields, done properly

Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. Typical jobs include floor or wall movement joints that have failed and a shower that leaks however often it’s resealed, across leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints.

Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.

All our work comes with a 12-month guarantee.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

What we’re called out for in St George's Fields

Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.

Look out for any of the following:

  • Sealant applied over old sealant that has lifted
  • Movement joints that have split or pulled away
  • Dark patches showing through the sealant
  • Thick, messy sealant smeared over tiles

As a London address, St George's Fields can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.

For site and facilities teams at buildings such as St George's Cathedral Catholic Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Elephant & Castle station, a joint that keeps failing is best fixed properly while the property is empty.

DIY versus a professional finish

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’re set on DIY, put the effort into 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.

How it works

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out in most cases. For a job in St George's Fields, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Old beads and residue are removed down to clean surfaces.
  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.

Before we arrive

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

FAQs for St George's Fields

Can you help a landlord with a rental near Elephant & Castle station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

I live in a flat in St George's Fields. Can a failed seal leak into the flat below?

Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.

Do you cover St George's Fields?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes St George's Fields.

How do I get a quote for remedial sealant in St George's Fields?

It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Someone sealed over the old bead. Can you fix it?

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.

Can old silicone be taken off without scratching the tiles?

Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.

Surface by surface

Over-sealed & botched joints

A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, and then we reseal it neatly.

Leaking trays & enclosures

A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.

What affects the cost of remedial sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How easy the joints are to reach
  • Working hours on commercial sites
  • The number and length of the joints
  • Which sealant suits the joint

The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

What to tell us when you ask for a quote:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Access, such as stairs, a lift or height
  • A few pictures by email, if you can
  • Whether it’s a home or a business

Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Keep movement joints clear of mortar and paint
  • Keep bleach and abrasives off the bead
  • Air the bathroom so the sealant can dry
  • Have loose fittings fixed before resealing

If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.

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.
