About our washroom sealing in Great Wakering

In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on urinals and WCs, vanity units and basins and kitchens and tea points, and the usual reasons a site gets in touch are stained or open joints at kitchen sinks and worktops and open joints at the base of cubicle panels. Whoever orders the work in Great Wakering, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Jobs in a smaller place such as Great Wakering are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. A list and photos let us quote and plan so it’s done in one visit where possible.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Quoting for work in Great Wakering

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Travel to remote or island sites

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Your programme or deadline
  • Specification clauses that apply
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Maintenance after handover

Once the work is signed off, these steps help:

  • Act on the first split you see at a shower tray
  • Clean sealant with gentle products and a soft cloth
  • Respect the cure time before reopening each room
  • Make sure washroom ventilation is running

Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.

Busy facilities in and around Great Wakering

With the shore within about 2 miles, Great Wakering counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, and the quieter months are the natural time to reseal. At about 39 miles from central London, Great Wakering is within reach of the capital. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Healthcare estates like Southend University Hospital (to the west of Great Wakering) expect contractors to follow their permits and cleaning rules in every washroom. Where you’re responsible for a hall attached to a building such as Church of St Nicholas, its kitchen and toilets need sealant that stays cleanable.

Questions we’re asked in Great Wakering

Is Great Wakering too small for you to travel to?

No. Places such as Great Wakering are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like University of Essex for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will cleaning remove black mould from sealant?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

From enquiry to sign-off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Several jobs near Great Wakering can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Share the asbestos register for older buildings
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

  • Washrooms that look worn because of the sealant
  • Resealing that didn’t last because the old bead stayed

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • How they handle RAMS and site documents
  • Their pre-qualification and accreditations
  • How long is the guarantee, and what does it include?

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.
