About our washroom sealing in Mundy Bois

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels so they get particular attention. We work on kitchens and tea points, vanity units and basins and IPS panels and cubicles, and the usual reasons a site gets in touch are open joints along basins and vanity units and black mould inside silicone joints that cleaning can’t shift. Looking for mastic applicators who cover Mundy Bois? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Mundy Bois are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks through tanking or membranes below the finishes
  • A dripping waste or valve behind a panel
  • A room that stays damp because ventilation isn’t working

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.

Joints and surfaces we work on

  • Kitchens and tea points
  • IPS panels and cubicles
  • Accessible toilets and changing rooms
  • Urinals and WCs
  • Vanity units and basins
  • Showers, trays and wet room floors

Questions we are asked in Mundy Bois

What paperwork can you provide for a job in Mundy Bois?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Mundy Bois off your patch?

No. Places such as Mundy Bois are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Mundy Bois can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we’ll plan around them.

Why deal with it now?

A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Older rural buildings around Mundy Bois move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
