Remedial sealant in North Mundham

Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. If you have smears and lumps from a botched reseal and floor or wall movement joints that have failed, we can put it right, on mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints alike.

Around North Mundham, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.

All of our work is guaranteed for twelve months, in North Mundham and everywhere else we cover.

What happens if it’s left?

Mould under a bead cannot be reached by cleaning. The layers have to come out. Older cottages and farmhouses around North Mundham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Common questions in North Mundham

Is North Mundham within the area you cover?

Yes, North Mundham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

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

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

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

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

We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

Can you take off two layers of silicone?

Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.

Can I add another job to the visit?

Yes. More than one area can go on one quote.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

How long does remedial resealing take?

It takes a few hours for a typical bath or shower, longer where several layers have been applied. You will know the timing when we quote.

What we cannot put right

A few problems are outside what sealant work can do:

  • A cracked shower tray or bath (that needs repair or replacing)
  • A bath, tray or worktop that moves until it’s properly fixed
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Signs you need remedial sealant in North Mundham

Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.

People generally contact us after spotting one of these:

  • Sealant peeling off a dusty or damp surface
  • Worktop sealant that has shrunk and split
  • Products that weren’t meant for the joint
  • A second bead peeling off the first

For an older house near a landmark such as The Parish Church of St Stephen, older homes can move a little, which is hard on rigid grout and tired sealant.

Questions to ask before you book

  • Whether you can choose the colour
  • Who does the work, and how experienced they are
  • What guarantee comes with the work
  • Are they insured?

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. In a small place like North Mundham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. Every layer of old sealant is cut and cleaned out.
  3. We clean the joint, treat any mould and let it dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. We tool the joint and tell you about anything else that needs attention.

Preparing for the visit

  • Mention if the joints have been sealed before
  • For indoor joints, keep the area dry beforehand if you can
  • Move anything stored near the joints

How to get a quote
