Bathroom resealing for homes and businesses in Dartford

Homes in Dartford have the same weak spots as anywhere else: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. Typical jobs include black mould in the silicone that won’t clean off and a bead that has pulled away from the tiles, on wet rooms, sinks & splashbacks and baths.

Dartford mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Whatever their age, sealant and grout tend to go before anything else.

There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional 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 fails, we can still redo it.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What the job involves on each surface

Kitchen worktops & upstands

Worktop joints get wet and wiped every day. We seal them in a colour that suits the worktop.

Wet rooms

Wet rooms rely on sound joints at floor and wall junctions. They get anti-fungal sanitary silicone, and our work is on the visible joints only.

What happens if it’s left?

The difference in a professional reseal is mostly what you do not see: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Skip those steps and even the best silicone fails early. Around Dartford, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Why Dartford customers choose us

  • We agree the colour with you first
  • Colour picked to suit the job

Common problems we fix in Dartford

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.

Most people get in touch after spotting one of these:

  • Black mould in the silicone that will not clean off
  • A reseal done over the top of the old bead
  • Water getting behind the bath panel
  • Gaps where the bath or tray has moved

Schools such as Dartford Primary Academy are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

What to look for in a quote

  • Are they insured?
  • Is the old sealant removed completely?
  • What happens if the job turns out different
  • What product goes in the joint

When it isn’t the sealant

In fairness, some problems need a different trade:

  • Loose or hollow tiles, or failed tanking behind them
  • Cracked or missing grout between tiles (that is regrouting)
  • A bath or tray that moves because it isn’t properly supported

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Surfaces we seal

How it works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a morning or an afternoon for most single baths and showers. For a job in Dartford, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  1. We cover the area around the joints we are working on.
  2. Old sealant is sliced away and the residue removed.
  3. We treat any mould and let the joint dry properly.
  4. Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
  5. The joint is finished neatly and we explain when it can get wet.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in

Quotes for bathroom resealing in Dartford

  • A few pictures by email, if you can
  • Whether it’s a home or a business
  • Any previous sealing or DIY work
  • Any access issues, like height or stairs

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

Bathroom resealing around Dartford

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

If you live in an older home near Church of the Holy Trinity, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Dartford station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
