About our washroom sealing in Fawkham Green

In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve sealant stained black around basins and showers and shower tray joints that have opened up, across showers, trays and wet room floors, kitchens and tea points and IPS panels and cubicles. Searching for sealant specialists in Fawkham Green? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Community buildings around smaller places like Fawkham Green have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Leave signs up until the cure time is over
  • Don’t leave an open joint at a basin or tray
  • Make sure washroom ventilation is running
  • Avoid scourers and harsh descalers on silicone

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Questions about Fawkham Green

Is a hospital such as Darent Valley Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Must a hotel around Fawkham Green close while you work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Panel boards already damaged by water
  • A room that stays damp because ventilation isn’t working

If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

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

Cost factors for washrooms and wet areas

The price varies from site to site. Expect it to depend on:

  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements
  • The product specified
  • Working within restricted access windows

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Any specification or named product
  • The postcode of the building
  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send details through our quote form.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a building around Fawkham Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Send your site hours and access windows
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
