Washroom sealing for Three Mills sites

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

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Three Mills, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Before we start on site

  • Send your site hours and access windows
  • Move anything stored against the joints
  • Point out parking and an unloading spot

Surface by surface

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Stained or split joints here trap smells and look unhygienic.

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Resealing early protects the unit.

Do you need washroom sealing in Three Mills?

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Things that usually lead to an enquiry:

  • Urinal joints that look unhygienic
  • Kitchen worktop joints that can’t be kept clean
  • Shower tray joints that have opened up
  • Complaints from staff, guests or users about tired washrooms

If you manage an office at a site such as Crescent Court Business Centre, under half a mile south-east of Three Mills, the washrooms and tea points can be done a floor at a time.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • Their public liability cover
  • How they’ll work around occupants
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Three Mills: questions and answers

Do you work in occupied care homes around Three Mills?

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

Can you work around term dates at a campus such as Arden University Stratford Campus?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you quote from photographs?

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

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Failed tanking beneath a wet-room floor or behind tiles
  • A room that stays damp because ventilation isn’t working
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Maintenance after handover

Once the work is signed off, these steps help:

  • Share your site rules when you send details
  • Clear standing water from shower floors where possible
  • Report split joints at trays and basins early
  • Brief cleaning staff to treat joints gently

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
