How we handle remedial sealant in Gravesend

Remedial jobs in Gravesend usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We are often asked to deal with thick, messy sealant smeared over tiles and repeat leaks from the same joint, across mouldy bath & shower sealant, expansion joints and shrunken worktop sealant.

Being in a small place like Gravesend makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Surface by surface

Leaking trays & enclosures

When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.

Windows & doors

Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.

What happens on the day

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Gravesend needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. New sealant goes in once the joint is dry, and is tooled smooth.
  5. We give you the cure time and explain what caused the failure.

Before we arrive

  • Clear items away from the joints we are working on
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know if you’ve seen damp or leaks

When it isn’t the sealant

It helps to know what we cannot do:

  • Water damage behind tiles that needs a tiler
  • Movement from fittings that are not supported
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

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

What we seal

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

Remedial sealant in Gravesend: local notes

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

For landlords with property near Bishops Stortford station, botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Do you need remedial sealant in Gravesend?

Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.

People normally contact us after spotting one of these:

  • Decorators’ caulk around a bath or shower
  • Movement joints that have split or pulled away
  • Over-sealed joints coming away
  • Kitchen joints letting water behind the worktop

If you look after a building such as Albury Church of England Voluntary Aided Primary School, 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.

Our hiring checklist

What affects the cost of remedial sealant

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

  • The number of rooms or windows
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • Access and height

Doing several joints on one visit usually makes better use of the time than several visits. We’ll send you a clear quote for the lot.

Helping us quote

When you call or email, it’s useful to know:

  • Photos by email, if that’s easy
  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved
  • Access, such as stairs, a lift or height

Need a quote? Please call 0345 464 0079 or send us an email with a few details. We will explain what we’d do and give you a clear price before work begins.

Leave it or put it right?

Another bead over the top won’t fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Gravesend can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why us?

  • Anti-fungal silicone where joints get wet
  • 20+ years of sealant experience
  • Neat joints and a tidy finish
  • An ARBOMaster approved applicator

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Don’t point over movement joints
  • Check ceilings under showers for marks
  • Run the fan after every shower
  • Use a soft cloth, not a scourer, on silicone

If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.

A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Questions from Gravesend

Is Gravesend in your area for remedial sealant?

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

Do you cover smaller places like Gravesend?

Yes. Gravesend is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

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

In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.

Do you offer different sealant colours?

We help you choose a colour that suits. The product needed can limit the range.

How long does the work take?

That depends on how many layers there are and how many joints. You will have a timescale before any work begins.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Can tenants book the work?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Can you take off two layers of silicone?

Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
