Washroom sealing in Bix

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

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. Rural sites near Bix may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  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.

What we need from you

  • Let us know about inductions and permits
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in

Advice

About our washroom sealing in Bix

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. Most enquiries involve stained or open joints at kitchen sinks and worktops and complaints from staff, guests or users about tired washrooms, across accessible toilets and changing rooms, vanity units and basins and urinals and WCs. A single leaking joint is often how a building in Bix first comes to us: we look at the rest while we’re there and tell you what we find.

Rural businesses near smaller places such as Bix, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Bix clients

Is a smaller place like Bix outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will all the washrooms in our Bix building be closed at once?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Is it possible to just clean mouldy silicone?

Usually not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Leave it or put it right?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Bix. Send photographs of each area and we will quote for the lot.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Sanitary sealant for Bix buildings

Bix lies roughly 37 miles out from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

At a hospital like Townlands Memorial Hospital, 2.3 miles to the south-east of Bix, patient and staff washrooms are best done in short phases agreed with the ward. Halls linked to places like Church of St James host groups all week, which is hard on kitchen and toilet sealant.

Bix is about 6 miles north of Caversham, in Oxfordshire. Any commercial site in Bix is covered, for single jobs and planned programmes alike. Bix is one of 423 places we cover in Oxfordshire. Reading is covered too, some 8 miles away.

We take on washrooms and wet areas across the RG9 postcode area. Buildings on White Lane and Rectory Lane are within our area for washrooms and wet areas. If your building is just outside Bix, we cover Middle Assendon (1 mile north-east), Lower Assendon (1 mile south-east), Fawley Bottom (1 mile north-east), Catslip (2 miles north-west) and Shepherd's Green (2 miles south-west). A short drive away, we cover Didcot (13 miles west), Thame (13 miles north), Henley-on-Thames (3 miles south-east), Benson (8 miles north-west), Chinnor (10 miles north) and Wallingford (8 miles west).

  • The site’s rules and procedures
  • Access and working height
  • Travel to remote or island sites
  • How much existing material needs removing

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we need to price the job

A few photographs plus some basic facts will normally do. It helps to include:

  • The asbestos register, for older buildings
  • The site address and postcode
  • When you need the work done
  • Whether the building will be occupied during the work

To get a fixed quote, call 01277 525 020 or send photos by email. You can also send details through our quote form.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.
