About our washroom sealing in Gossops Green

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on accessible toilets and changing rooms, vanity units and basins and kitchens and tea points, and what we are called in for most is discoloured joints around urinals and WC pans and mould spotting along silicone joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Gossops Green, preparation and product choice get the time they need.

Around Gossops Green, washroom work typically comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

  • Quantities, in metres or numbers
  • Joint width, depth and condition

Sanitary sealant for Gossops Green buildings

Gossops Green lies roughly 27 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open. Gossops Green has two care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

For a hotel such as Crawley Hotel, 0.5 miles to the east of Gossops Green, resealing en suites a few rooms at a time keeps the rest available. At a college such as Crawley College, 1.1 miles east of Gossops Green, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Questions we are asked in Gossops Green

Could you schedule work at a campus like Crawley College for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Gossops Green off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What will the job cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email us with a description of the work.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

What sealant do you use in washrooms?

An anti-mould sanitary silicone in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we will set out a timescale with the quote.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Several jobs near Gossops Green can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Send any specification or drawings in advance
  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions

Surface by surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

Signs you need washroom sealing in Gossops Green

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Typical triggers for a call:

  • Discoloured joints around urinals and WC pans
  • Users noticing mouldy joints
  • Sealant lifting along a tray edge
  • Mould spotting along silicone joints

On an industrial estate such as Denvale Trade Park (1.1 miles east of Gossops Green), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Questions to ask before you appoint anyone

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Water from plumbing, not from a joint
  • Hollow tiles or loose panels behind the joint
  • Failed tanking beneath a wet-room floor or behind tiles

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.
