Washroom sealing for Westwick Row sites

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

What affects the price in Westwick Row

A fixed quote reflects the actual work. It takes account of:

  • How much existing material needs removing
  • Any access equipment needed
  • Site requirements such as inductions and permits
  • The product specified

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

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

  • Access details, including height
  • Asbestos survey details if the building is older
  • The postcode of the building
  • Approximate linear metres or a joint schedule

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

How we handle washroom sealing in Westwick Row

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about open joints along basins and vanity units and mould spotting along silicone joints, across showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Westwick Row, preparation and product choice get the time they need.

Halls and community buildings near places like Westwick Row are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Westwick Row: questions and answers

Will you plan work around the academic year at somewhere like West Herts College?

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.

Is a smaller place like Westwick Row outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Which silicone is right for commercial washrooms?

It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

When to bring in 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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How the job changes by surface

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

Urinals and WC pans

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

What we’re called out for in Westwick Row

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Clients usually get in touch after noticing one or more of the following:

  • Gaps where vanity tops meet the wall
  • Resealing that didn’t last because the old bead stayed
  • Stained sealant around pans and urinals
  • Complaints from staff, guests or users about tired washrooms

At a hospital like Hemel Hempstead Hospital, 2.1 miles west of Westwick Row, patient and staff washrooms are best done in short phases agreed with the ward.

Our contractor checklist

Leave it or put it right?

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. One visit to deal with every failing joint makes more sense than several trips to a place like Westwick Row. Photos of every joint help us quote for the whole job.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Matching to RAL references, product permitting
  • One contact handling all your sites
  • Over 20 years of commercial sealing
  • Standard and matched colours in many product ranges

See what affects the cost and how we’re accredited.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes between a morning and a week or so, set by the number of rooms and the phasing you need, and we clear our waste as we work. If others near Westwick Row need work, visits can be combined. A fixed quote is given before anything starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Point out any areas we must not close
  • Point out parking and an unloading spot
  • Move anything stored against the joints
