Looking after it afterwards

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

  • Run the fan after every shower
  • Look for stains below bathrooms now and then
  • Never fill a movement joint with mortar or grout
  • Clean sealant with mild products only

Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.

Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

Remedial sealant for homes and businesses in Richmond

Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. Typical jobs include sealant that came away because the surface wasn’t prepared and kitchen joints letting water behind the worktop, across expansion joints, leaking tray & enclosure joints and mouldy bath & shower sealant.

Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Richmond, getting the joints right keeps water where it belongs and the room looking clean.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

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 doesn’t work out, we can still put it right.

Common questions in Richmond

I live in a flat in Richmond. 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.

Can you help a landlord with a rental near Richmond station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

What does remedial sealant cost?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done.

Can old silicone be taken off without scratching the tiles?

Yes, with care. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before we start.

What happens if the problem is the tray or the plumbing?

We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.

Are you fully insured?

Yes. We are fully insured for every job we do.

Honest limits

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

  • Movement from fittings that are not supported
  • A leaking trap, valve or supply pipe
  • A cracked shower tray or bath (that needs repair or replacing)

If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

What we seal

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

Landlords, agents and businesses in Richmond

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

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

How the visit works

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Richmond, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. Surrounding tiles, trays and frames are protected first.
  2. Every layer of failed sealant is stripped out.
  3. The joint is degreased and checked for movement and leaks.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we are working on
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

Leave it or put it right?

Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Richmond, the repair is bigger than the sealant job would have been.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Why book with us

  • Old sealant always removed completely
  • Colour picked to suit the job
  • Homes, businesses and hotels
  • Trusted Arbo and Everbuild sealants

How we quote for remedial sealant

There’s no set price list. The quote depends on:

  • Working hours on commercial sites
  • The number and length of the joints
  • The type of sealant required
  • Whether there’s mould to deal with

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What we need to know

Before you ask for a quote, have a think about:

  • Access, such as stairs, a lift or height
  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • Whether it’s a home or a business

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.

What remedial sealant looks like in Richmond

In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. There are hotels and other places to stay in and around Richmond. Hotel bathrooms are part of our work as well as homes, and can be done room by room.

If you live in an older home near The Vineyard Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Richmond station, a joint that keeps failing is best fixed properly while the property is empty. Richmond is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
