About our bathroom resealing in Greenhill

A bead that has gone black, split or come away shouldn’t be left until there’s a leak. A photo of the joints helps when you ring 0345 464 0079 or drop us an email, and you will get a clear quote for bathroom resealing in Greenhill. We work on kitchen worktops & upstands, shower trays & enclosures and baths, and people most often call us about new sealant laid over old sealant that is now lifting and water getting behind the bath panel.

In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Greenhill are no different.

Whatever the size of the job, it’s backed by our one-year guarantee.

Signs you need bathroom resealing in Greenhill

Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.

Signs it’s time to call us include:

  • A reseal done over the top of the old bead
  • Water escaping at the shower enclosure
  • Black spots spreading through the bead
  • A messy, uneven bead from a previous reseal

Rented homes near Hampstead Heath station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

What your quote should include

  • How the joint is cleaned and prepared
  • What product goes in the joint
  • Whether they seal over old material or remove it
  • How long to leave it before use

How we quote for bathroom resealing

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

  • Working hours on commercial sites
  • Which sealant suits the joint
  • How much there is to do
  • Access and height

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode
  • How we’d reach the joints

To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.

When it is not the sealant

We won’t take on work that won’t last, so here’s what sealant can’t put right:

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

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

What we seal

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

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. If we find a deeper problem, you will hear it from us. 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 Greenhill.

Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Why Greenhill customers choose us

  • Tidy, careful work
  • Experience in homes, commercial sites and hotels
  • Approved under the ARBOMaster scheme
  • Sealant colour chosen to suit

What the job involves on each surface

Sinks & splashbacks

The edge of an inset sink is a common place for water to get under the worktop. Where the sealant around the visible edge has failed, we renew it.

Baths

A bath shifts slightly every time it’s filled, so it’s filled with water before the bead goes on. That way the joint is laid with the bath at its heaviest and is not torn the first time it’s used.

Greenhill questions

I let a flat near Hampstead Heath station. Can you help?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Is parking a problem for a job in Greenhill?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Does the resealing come with a guarantee?

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

How long before the new sealant can get wet?

After around 24 hours in most cases. We’ll tell you the cure time for the product we used.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.

Do you cover Greenhill?

Yes, we do. Greenhill is part of the area we cover.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

How the visit works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes half a day or less for one room, longer when the kitchen is included for a typical job. In Greenhill, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First, each joint is checked for movement and signs of water.
  2. Every trace of the old bead is removed, including the thin smear on the tiles.
  3. Joints are degreased and any mould is treated.
  4. With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
  5. We tool the bead to a neat finish and give you the cure time, normally around 24 hours.

Getting ready for the visit

  • Keep children and pets away from the work area
  • For indoor joints, keep the area dry beforehand if you can
  • Mention any leaks or damp you’ve noticed

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
