Washroom sealing in Farthing Green, done properly

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 mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. We work on urinals and WCs, vanity units and basins and showers, trays and wet room floors, and the failures we are asked to look at most are open joints at the base of cubicle panels and gaps where vanity tops meet the wall. Searching for sealant specialists in Farthing Green? We’ve been sealing commercial buildings since 2005.

Rural businesses near smaller places such as Farthing Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Quoting for work in Farthing Green

To price the job, we consider:

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Joint width, depth and condition

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

However big the job, the same details help:

  • Whether an asbestos survey exists
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • Your programme or deadline

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.

FAQs: Farthing Green

Will all the washrooms in our Farthing Green building be closed at once?

Typically only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

Is Farthing Green too small for you to travel to?

Not at all. Farthing Green is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Are you fully insured?

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

How much does the work cost?

Each job is quoted on its own details. For yours, phone 01277 525 020 or use the quote form with a description of the work.

Can you clean the mould off instead of resealing?

Typically not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

What happens if it’s left?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Halls, stores and units around places like Farthing Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What the job involves on each surface

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath and point it out if water appears to rise from below.

Wet areas in Farthing Green’s workplaces

Farthing Green lies roughly 37 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.

Do you need washroom sealing in Farthing Green?

Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.

It’s worth sending us details if you spot any of the following:

  • Open joints along basins and vanity units
  • Shower tray joints that have opened up
  • A new bead over an old one coming away
  • Open joints at the base of cubicle panels

For an occupier at a site such as Barradale Farm Industrial Estate (1.1 miles south-east of Farthing Green), the canteen and welfare facilities need cleanable joints as much as any office.

What your quote should include

  • Their public liability cover
  • Their plan for phasing and protecting the area
  • Their approach to joint depth and backing
  • How the existing material will be dealt with
