Washroom sealing for businesses in Shirley Oaks

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking half a day to a day per washroom, depending on the number of fittings. In Shirley Oaks, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Warn occupants and staff about the work

Advice

Washroom sealing in Shirley Oaks

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with shower tray joints that have opened up and users noticing mouldy joints, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Shirley Oaks tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Location, for remote and island sites
  • The size and state of each joint
  • Phasing around occupants
  • How accessible the joints are

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When to call us in Shirley Oaks

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Any of the following is a good reason to get the joints checked over:

  • Stained or open joints at kitchen sinks and worktops
  • Open joints along basins and vanity units
  • Urinal joints that look unhygienic
  • Sealant laid over old silicone and now peeling

Toilets at places like Whitgift Centre, 1.9 miles west of Shirley Oaks, are cleaned constantly, so silicone needs to be sound and smooth.

What your quote should include

  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?
  • Do they follow the manufacturer’s priming guidance?
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Questions about Shirley Oaks

Can work in a care setting near Shirley Oaks go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Why it’s worth doing now in Shirley Oaks

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • 12-month guarantee on workmanship
  • One contact handling all your sites
  • A fixed quote before work starts
  • Products installed to the manufacturer’s instructions

Looking after the joints

For the best life from the joints:

  • Include joints in routine washroom inspections
  • Avoid scourers and harsh descalers on silicone
  • Note failing joints building by building
  • Tell us about infection-control or permit rules before we quote

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Busy facilities in and around Shirley Oaks

The 2 miles around Shirley Oaks include seven care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs. Busy London buildings need some toilets open at all times, so resealing goes floor by floor, agreed with the facilities team.

Toilets at colleges like Croydon College (1.7 miles west of Shirley Oaks) take heavy use from students and staff alike. Halls linked to places like Shirley Methodist Church host groups all week, which is hard on kitchen and toilet sealant.
