Sanitary sealant for Westfield buildings

Westfield has a number of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. Central London is about 24 miles from Westfield. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Colleges such as Woking College (to the north-east of Westfield) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Welfare facilities in units on estates such as Martlands Industrial Estate (to the south-west of Westfield) have showers, toilets and kitchens with sealant that works hard.

Westfield is about 1 mile south-east of Woking, in Surrey. If you’re looking for washroom sealing in Westfield, we can help, as we do across Surrey. Westfield is one of 379 places we cover in Surrey for washrooms and wet areas. For work in that direction, see our Reading page (21 miles or so).

Washroom sealing for commercial buildings in Westfield

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. We are fully insured. Our workmanship is guaranteed for 12 months. We work on IPS panels and cubicles, urinals and WCs and vanity units and basins, and what we’re called in for most is a new bead over an old one coming away and stained or open joints at kitchen sinks and worktops. Facilities teams, main contractors and managing agents in Westfield tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

A place of Westfield’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we’re called out for in Westfield

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

Typical triggers for a call:

  • Shower tray joints that have opened up
  • Washrooms that look worn because of the sealant
  • Sealant stained black around basins and showers
  • Stained or open joints at kitchen sinks and worktops

For a site such as Woking Community Hospital, which lies north of Westfield, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with

Our contractor checklist

Different surfaces, different methods

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a site in Westfield, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open

Leave it or put it right?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Small buildings around Westfield suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

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

Why us?

  • Work carried out by CSCS-carded applicators
  • CHAS accredited
  • Public liability insurance in place
  • One contact handling all your sites

Take a look at what affects the cost and our accreditations and insurance.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes
  • A room that stays damp because ventilation isn’t working

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

Where we work in Westfield

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

Questions we are asked in Westfield

Will our hotel in Westfield need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.

Can you take on a job at a hospital such as Woking Community Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

Which silicone is right for commercial washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Is Westfield in your area?

Yes. Westfield falls within our area, and you can speak to us on 01277 525 020 or email drawings and photos to get started.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
