Washroom sealing in Ringshall, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on IPS panels and cubicles, accessible toilets and changing rooms and vanity units and basins, and the failures we are asked to look at most are urinal joints that look unhygienic and open joints along basins and vanity units. A specialist sealant contractor works differently from a general builder: on jobs in Ringshall, preparation and product choice get the time they need.

Farm shops, cafés and venues in converted rural buildings around places like Ringshall have busy toilets and kitchens. We plan the work around bookings and opening times.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Questions about Ringshall

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

Typically only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Is Ringshall off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. Smaller jobs around Ringshall can be grouped with others nearby. 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. We agree which rooms close and when, so users always have somewhere to go.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

What affects the price in Ringshall

The price varies from site to site. Expect it to depend on:

  • Removal of failed or old sealant
  • Any access equipment needed
  • Quantities, in metres or numbers
  • Location, for remote and island sites

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 rules also count.

What we need to price the job

However big the job, these details speed things up:

  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • Specification clauses that apply

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or use the quote form.

What we are called out for in Ringshall

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water, and they stain, crack or wash out.

If one of these sounds familiar, it’s time for a closer look:

  • Shower tray joints that have opened up
  • Failed sealant in a tea point or staff kitchen
  • Sealant stained black around basins and showers
  • Complaints from staff, guests or users about tired washrooms

Hotels such as The Bridgewater Arms Hotel, 0.5 miles south-east of Ringshall, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Squeegee showers and trays after busy periods
  • Note failing joints building by building
  • Make sure washroom ventilation is running
  • Act on the first split you see at a shower tray

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

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.
