About our remedial sealant in Cadmore End

A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you’re dealing with black mould underneath the bead and repeat leaks from the same joint, we can help, on failed movement joints, mouldy bath & shower sealant and expansion joints alike.

In a village or hamlet like Cadmore End, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

All our work is covered by a one-year guarantee.

What sealant work cannot fix

It helps to know what we cannot do too:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • Movement from fittings that aren’t supported

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

Surfaces we seal

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

Signs you need remedial sealant in Cadmore End

Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.

The problems people generally mention when they call include:

  • Black mould underneath the bead
  • Repeat leaks from the same joint
  • Thick, messy sealant smeared over tiles
  • Movement joints that have split or pulled away

If you let a flat or house near Saunderton station, a joint that keeps failing is best fixed properly while the property is empty.

Questions to ask before you book

  • How the colour is chosen
  • What the cure time is
  • What product goes in the joint
  • How the joint is cleaned and prepared

Choosing a sealant specialist

Aftercare tips

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

  • Look for stains below bathrooms now and then
  • Don’t wait for a small gap to become a leak
  • Never fill a movement joint with mortar or grout
  • Clean sealant with mild products only

Leave the new joint to cure fully before it gets wet or moves: usually around 24 hours, or as long as we advise.

A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.

What affects the cost of remedial sealant

We quote each job individually. These are the things that affect it:

  • When we can work, for business premises
  • Mould in or behind the old joints
  • How many areas need sealing
  • Access and height

What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before we start.

What we need to know

When you call or email, these details help:

  • Photos by email, if that’s easy
  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any access issues, like height or stairs

To get a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before we start.

Bathrooms and kitchens in Cadmore End

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

If you look after a building such as Cadmore End CofE School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Mary Le Moor, older homes can move a little, which is hard on rigid grout and tired sealant.

What happens on the day

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours, depending on how many layers have to come out, depending on how much there is to do. Somewhere like Cadmore End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. Finally we finish the joint and talk you through what we found.

Before we arrive

  • Let us know about parking restrictions
  • Clear the area around the work
  • Mention any leaks or damp you’ve noticed

Advice

Cadmore End questions

Is Cadmore End in your area for remedial sealant?

Yes, Cadmore End is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.

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

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Can you match the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Someone sealed over the old bead. Can you fix it?

Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Do you do commercial work?

Yes, regularly. We can plan bigger jobs in stages.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

DIY versus a professional finish

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What the job involves on each surface

Worktops & kitchens

Kitchen joints hold grease and residue, so we spend extra time cleaning.

Over-sealed & botched joints

Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and point out any existing damage.
