Washroom sealing for Purley sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. All of Greater London is in the ULEZ, and kerbside space in Purley can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  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. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open

Advice

Washroom sealing in Purley

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about failed joints along IPS and cubicle panels and gaps where vanity tops meet the wall, on kitchens and tea points, showers, trays and wet room floors and vanity units and basins. One point of contact handles commercial sealant work in Purley from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In Purley, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Washroom sealing around Purley: how the place shapes the job

There are a number of hotels within about 2 miles of Purley. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Busy London buildings need some toilets open at all times, which is why the work is split into phases agreed in advance.

For centre management at a site such as Whitgift Centre, 2.8 miles to the north of Purley, washroom work is planned around footfall. Hotels such as London Croydon Aerodrome Hotel, 1.5 miles to the north of Purley, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Purley is about 2 miles south-west of Croydon, in Greater London. Anywhere in CR8, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 764 places in Greater London, large and small. Sites around London have their own page, roughly 11 miles from Purley.

Business premises anywhere in CR8, CR2 and CR5 are within our area for washrooms and wet areas. Buildings on High Street, Church Road and Brighton Road are within our area for washrooms and wet areas. With the A2022 nearby, Purley is easy to get to with materials and equipment. Just outside Purley, we also work in Peaks Hill (1 mile north-west), Woodcote (1 mile west), Russell Hill (1 mile north), Roundshaw (1 mile north-west) and Woodcote Green (1 mile west). A short drive away, we cover London (11 miles north), City of Westminster (12 miles north), Marylebone (13 miles north), Kensington (12 miles north), St Pancras (13 miles north) and Shoreditch (13 miles north).

What affects the price in Purley

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • The size and state of each joint
  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

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

  • Any specification or named product
  • How the joints are reached, and at what height
  • The site address and postcode
  • When you need the work done

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Leaks through tanking or membranes below the finishes
  • Water from plumbing, not from a joint
  • Vanity carcasses that have swollen

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Questions we are asked in Purley

Do you work in occupied care homes around Purley?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Can work at a site such as Purley Language College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you use special sealant for toilets and showers?

Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Are you CHAS accredited and on Constructionline?

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

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Why it’s worth doing now in Purley

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Fully insured, including public liability cover
  • CSCS-carded applicators
  • Colours chosen to suit frames, cladding or finishes where possible
  • Coloured sealants to suit the setting, where available

Do you need washroom sealing in Purley?

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

If one of these sounds familiar, it’s time for a closer look:

  • Complaints from staff, guests or users about tired washrooms
  • Sealant laid over old silicone and now peeling
  • Open joints along basins and vanity units
  • Panel joints letting water behind

At a college such as Purley Language College (less than half a mile west of Purley), washroom and kitchen sealant is best renewed in the holidays or in phases during term.
