Washroom sealing in The Hangers

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Washroom sealing in The Hangers, done properly

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve split or peeling sealant at shower trays and failed sealant behind washroom basins, across urinals and WCs, IPS panels and cubicles and accessible toilets and changing rooms. Facilities teams, main contractors and managing agents in The Hangers tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

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

Your questions answered

What site paperwork comes with a job in The Hangers?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is The Hangers off your patch?

No. Places such as The Hangers are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.

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.

Are you CHAS accredited and on Constructionline?

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

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Phasing around occupants
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • A wide shot and a close-up of the area
  • The product your specification calls for
  • The postcode of the building
  • The asbestos register, for older buildings

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or send details through our quote form with what you know.

Different surfaces, different methods

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed and any permits the site uses.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. Smaller jobs around The Hangers can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Before we start on site

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

Ask for a quote

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email the details over.

Advice

Looking after the joints

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

  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured
  • Don’t leave an open joint at a basin or tray
  • Keep extract fans working and vents clear

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.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

What we’re called out for in The Hangers

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead, so it soon lets go.

Most enquiries start with something like this:

  • Failed sealant in a tea point or staff kitchen
  • A new bead over an old one coming away
  • Urinal joints that look unhygienic
  • Split or peeling sealant at shower trays

For buildings on a site such as Swanmore Business Park, which lies south of The Hangers, washrooms and tea points can be resealed in phases through the working week.

Comparing quotes

  • What site paperwork they can supply
  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
