FAQs for River

Can you do remedial sealant in River?

Yes. We work across London and the South East, and River is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

Do you work for landlords with property near Kearsney station?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Can you remove sealant that’s been put over old sealant?

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.

What should I tell you?

A short description and the location. We’ll ask anything else we need to know.

Can you remove old sealant without damaging the bath?

Yes, with care. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that’s already there.

Can failed expansion joints be resealed?

Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.

Remedial sealant in River

In River, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. We work on expansion joints, failed movement joints and shrunken worktop sealant, and common reasons people get in touch are worktop sealant that has shrunk and split and wide, uneven beads that look worse than the old ones.

Smaller places like River still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

How it works

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. A visit to River is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

Preparing for the visit

  • Mention any parking rules near the property
  • Keep children and pets away from the work area
  • Tell us about access, such as stairs, a lift or high-level joints

Do you need remedial sealant in River?

How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.

People usually contact us when they notice one of these:

  • Mould trapped under a layer of silicone
  • Leaks that keep coming back after resealing
  • Sealant peeling off a dusty or damp surface
  • Worktop sealant that has shrunk and split

If you let a flat or house near Kearsney station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Questions to ask before booking

  • Who turns up on the day
  • What preparation is included
  • What the quote includes, VAT included or not
  • What the cure time is

What we can’t put right

We won’t take on work that won’t last, so these are the limits:

  • Sealant in an older building that needs testing for asbestos first
  • A tray or worktop that needs refixing first
  • Cracks in the fitting rather than the joint

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

Where we work in River

  • Failed movement joints
  • Expansion joints
  • Mouldy bath & shower sealant

  • Shrunken worktop sealant
  • Botched or over-sealed joints

Quotes for remedial sealant in River

You’ll get a clear quote before any work starts. It’s based on:

  • Any working-time requirements on site
  • Any mould that needs treating
  • The amount of work
  • The number of rooms or windows

The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Asking for a quote

You don’t need to know the technical terms. It helps if you can tell us:

  • Any access issues, like height or stairs
  • Roughly how big the job is
  • A few photos by email, if you can
  • Where the job is, and your postcode

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Bathrooms and kitchens in River

River is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Schools such as River Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Peter include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Do not wait for a small gap to become a leak
  • Don’t point over movement joints
  • Check trays and worktops do not move
  • Keep an eye on the ceiling below the bathroom

Keep an eye on the joint at first, particularly where the original failure was caused by movement. If anything changes, just phone 0345 464 0079 or email us.

Don’t keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
