How we handle washroom sealing in Great Tew

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. Site teams most often ask us about failed sealant behind washroom basins and shower tray joints that have opened up, across vanity units and basins, urinals and WCs and showers, trays and wet room floors. A specialist sealant contractor works differently from a general builder: on jobs in Great Tew, preparation and product choice get the time they need.

In and around smaller places like Great Tew, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Work we carry out in Oxfordshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we will come back to it.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Condensation from failed extract fans
  • A dripping waste or valve behind a panel

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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

FAQs: Great Tew

What site paperwork comes with a job in Great Tew?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will the toilets in our Great Tew building be out of use?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you work in Great Tew?

Yes. Great Tew is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email a schedule or drawings.

How soon can a washroom be used after resealing?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes half a day to a day per washroom, depending on the number of fittings. If others near Great Tew need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another 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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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

  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits
  • Make sure the joints can be reached

Advice

Why it’s worth doing now in Great Tew

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. One visit to deal with every failing joint makes more sense than several trips to a place like Great Tew. Send photos of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Surface by surface

Changing rooms and gyms

Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we’ll say if the trouble looks to be beneath the floor.

Washroom sealing around Great Tew: how the place shapes the job

Central London is about 65 miles from Great Tew. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

Schools such as Great Tew County Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. Welfare facilities in units on estates such as Enstone Airfield Industrial Estate, 2.2 miles south of Great Tew, have showers, toilets and kitchens with sealant that works hard. Where you are responsible for a hall attached to a building such as Church of St Michael and All Angels, its kitchen and toilets need sealant that stays cleanable.

What affects the price in Great Tew

The price varies from site to site. It mainly depends on:

  • Access and working height
  • Location, for remote and island sites
  • Joint width, depth and condition
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

  • The asbestos register, for older buildings
  • Your programme or deadline
  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
