Bathroom resealing for Thamesmead homes and businesses

Bathroom resealing in Thamesmead

A reseal only lasts if the joint is properly prepared. Every bit of old silicone comes out, down to the thin film left on the tiles, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. We work on sinks & splashbacks, baths and shower trays & enclosures, and the jobs we see most are a bead that has pulled away from the tiles and gaps between the worktop and the wall.

London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Thamesmead more than a cosmetic job.

There’s a 12-month guarantee on every job, whatever its size.

Thamesmead homes and their sealant

London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.

For an older house near a landmark such as St Paul, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Abbey Wood station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

What happens on the day

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes around two hours for one bath or shower, longer for a whole bathroom, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. We start by protecting the area and stripping out the old bead.
  2. The joint is cleaned, degreased and treated for mould.
  3. The joint is left to dry, and baths are filled with water first.
  4. We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
  5. We tidy up and give you the cure time, generally around 24 hours.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules
  • Mention any parking rules near the property

Advice

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Tiles that have come away from the wall
  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • Water getting in through the grout rather than the sealant

If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

  • Shower trays & enclosures
  • Kitchen worktops & upstands
  • Baths
  • Wet rooms
  • Sinks & splashbacks
  • Basins & vanity units

Signs you need bathroom resealing in Thamesmead

Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.

Keep an eye out for these signs:

  • Gaps between the worktop and the wall
  • Leaks into the floor or ceiling below
  • Smears of silicone across the tiles
  • Sealant that has split, shrunk or peeled away

For site and facilities teams at buildings such as Jubilee Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Our hiring checklist

Common questions in Thamesmead

Can worn sealant in a flat in Thamesmead cause a leak downstairs?

Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.

Is parking a problem for a job in Thamesmead?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Is the work guaranteed?

Yes. We give a 12-month guarantee on every job, and we are ARBOMaster approved applicators.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

How long does it take to reseal a bath or shower?

It takes two to three hours for a typical bath, depending on how much old sealant there is. We’ll confirm how long your job needs when we quote.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Can I add another job to the visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Do you do kitchens as well as bathrooms?

Yes. Kitchen joints get extra degreasing before the new bead goes on, then we reseal in a colour to suit.

Surface by surface

Wet rooms

A wet room floor and its walls can move independently, so the internal corners need silicone rather than grout. Cracked grout in a corner can be cut out and replaced with silicone.

Basins & vanity units

The back of a basin gets wet every time someone washes. Corners behind basins are where mould tends to start, so it’s cut out and renewed just like a bath joint.

For landlords and businesses

We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.

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.

Keeping the joints in good condition

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

  • Wait for the cure time we give you
  • Dry the bead with a towel now and then
  • Never pick at the silicone with a blade
  • Do not leave water standing on kitchen joints

Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering helps the joint dry.

Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning normally will not remove it, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.

Why deal with it now?

Dealing with sealant early is a short job: the work takes a morning or an afternoon for most single baths and showers. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Thamesmead.

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
