Your questions about bathroom resealing in Hendon

Do you work for landlords with property near Hendon station?

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Is parking an issue for bathroom resealing in Hendon?

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.

What should I tell you?

Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.

Can you just seal over the old silicone?

No. New silicone won’t bond to old silicone, so it peels away and hides mould and water. All the old sealant comes out first.

My sealant has gone black. Can you sort it?

Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Bathroom resealing for homes and businesses in Hendon

Across Hendon, the joints we reseal are the ones that fail in any home: bath edges, tray joints, basin backs and kitchen upstands. Each one is stripped, cleaned and dried before new silicone goes in. If you’re dealing with new sealant laid over old sealant that is now lifting and failed sealant on the screen profile, we can help, whatever the surface.

London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Hendon, getting the joints right keeps water where it belongs and the room looking clean.

Whatever the size of the job, you get the same 12-month guarantee in Hendon and across Greater London.

Landlord and commercial work in Hendon

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

When it isn’t the sealant

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

  • A tray that rocks until it’s re-bedded
  • A cracked shower tray or bath (that needs repair or replacement)
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Surfaces we seal

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

What the job involves on each surface

Baths

Acrylic baths give a little under load, while steel and cast iron baths move less but still settle when full. Filling the bath first allows for that movement.

Sinks & splashbacks

Splashbacks in glass, tile or acrylic meet the worktop in a long joint. It’s resealed in white, clear or a colour to suit.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes around two hours for one bath or shower, longer for a whole bathroom and we leave things clean and tidy. In a London area like Hendon, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We cover the area around the joints we are working on.
  2. Old sealant is sliced away and the residue removed.
  3. Mould is treated, then the joint is left to dry thoroughly.
  4. Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
  5. The joint is finished neatly and we explain when it can get wet.

Before we arrive

  • On commercial sites, let us know about site rules
  • Mention any tricky access
  • Keep pets and children clear of the area while we work

Keeping the joints in good condition

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

  • Avoid abrasive pads on the sealant
  • Wipe up water along the back of the worktop
  • Check the joints every few months for splits or lifting
  • Keep bottles off the sealant line

Clean the silicone with care: warm soapy water and a soft cloth do the job. Avoid scouring pads and anything sharp, and a nicked bead lets mould in sooner.

Do not wait for a refit to deal with failed sealant. Like paintwork, sealant needs renewing from time to time, and replacing it when it fails protects the rest of the room.

Do you need bathroom resealing in Hendon?

Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, opening a hairline gap that lets water and crumbs in. Heat from the hob and strong sprays speed it along.

Signs it’s time to call us include:

  • A bead that has pulled away from the tiles
  • Damp behind the bath or under the tray
  • Gaps where the bath or tray has moved
  • Failed sealant on the screen profile

Hendon is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Leave it or put it right?

Tired sealant is not a reason to replace a bath or shower. A new bead often brings the whole room back, as long as the fittings themselves are sound. If we find a deeper problem, you will hear it from us. In a flat in Hendon, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
