How bathroom resealing works in NW7

A reseal only lasts if the joint is properly prepared. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. Common call-outs are for gaps where the bath or tray has moved and gaps between the worktop and the wall, on sinks & splashbacks, baths and basins & vanity units.

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes two to three hours for a typical bath, depending on how much old sealant there is.

  1. We look at every joint first and check for movement or leaks.
  2. Every trace of the old bead is removed, including the thin smear on the tiles.
  3. The joint is cleaned, degreased and treated for mould.
  4. When the joint is dry, and a bath has been filled with water, the new silicone goes on.
  5. We tool the bead to a neat finish and give you the cure time, generally around 24 hours.

Where we work in NW7

Homes across NW7 range from older properties to new builds, with plenty of rented property in places like Burnt Oak, Edgware and Church End. Bathroom resealing keeps bathrooms and kitchens watertight and looking cared for.

The South East is one of the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across NW7 is planned around the weather.

Mill Hill: If you look after a building such as St Paul's CofE Primary School NW7, we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Mill Hill Broadway station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Landlords, agents and businesses in NW7

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

Leave it or put it right?

Sorting it now is quick: the work takes a couple of hours for a single bath or shower. Left until water gets through, the job can grow to lifting panels, drying out and decorating.

What your quote should include

  • What product goes in the joint
  • How the surfaces are prepared before sealing
  • Who turns up on the day
  • How the colour is chosen

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Open a window or run the fan so the room dries
  • Use gentle cleaners on the silicone
  • Check the joints every few months for splits or lifting
  • Give the silicone its full cure time

In a kitchen, don’t let water sit along the back of the worktop and keep hot pans off the bead. The drier the joint stays, the longer it lasts.

Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.

What we are called out for in NW7

Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.

It’s worth asking for a quote if you see:

  • A joint torn by a bath that flexes
  • Damp behind the bath or under the tray
  • Shrunken sealant along the back of a worktop
  • Black spots spreading through the bead

NW7 questions

Can you do several jobs on one visit?

Of course. Doing several areas at once is normally more efficient.

Is it OK to put new sealant on top of the old bead?

No. A bead laid over old silicone soon starts to come away, because silicone doesn’t bond to silicone. We remove the old bead completely before resealing.

Do you work for letting agents?

Yes, regularly. We can quote for several properties at once.

Is it worth trying it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Will there be a smell?

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

Do I need to be at home?

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