Washroom sealing in Tongwell, done properly

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. Most enquiries involve failed sealant in a tea point or staff kitchen and complaints from staff, guests or users about tired washrooms, across IPS panels and cubicles, vanity units and basins and urinals and WCs. Whoever orders the work in Tongwell, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Tongwell still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Make sure washroom ventilation is running
  • Leave signs up until the cure time is over
  • Don’t leave trays and floors sitting wet
  • Act on the first split you see at a shower tray

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

FAQs: Tongwell

Is Tongwell off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Blakelands 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.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you do washroom sealing in healthcare settings?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. For work around Tongwell, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Send your site hours and access windows
  • Flag any permit to work we will need
  • For older buildings, check the asbestos register before work

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Quoting for work in Tongwell

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Travel to remote or island sites
  • Access and working height

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • The product your specification calls for
  • The site address and postcode

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Panel boards already damaged by water
  • Failed tanking beneath a wet-room floor or behind tiles
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
