Washroom sealing in Stubbington: the local picture

With the shore within about 1 mile, Stubbington counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready. Central London is about 67 miles from Stubbington. Business park offices have washrooms in daily use by staff, which is why the work is phased.

At a hotel such as Crofton Manor Hotel, which lies north of Stubbington, the quieter weeks are the time to reseal bathrooms. For a store at a site such as Speedfields Retail Park, 1.6 miles to the north-east of Stubbington, the staff room and customer toilets can be resealed in quiet periods. For a college such as Fareham College, 2 miles to the north-east of Stubbington, half-term and summer give the windows for washroom work.

Stubbington is about 2 miles south-west of Fareham, in Hampshire. Businesses, contractors and managing agents in Stubbington can call on us for washrooms and wet areas. Our Hampshire coverage takes in 723 places. Portsmouth is covered too, some 6 miles away.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

For main contractors, we work as the 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.

Common questions from Stubbington clients

Could you schedule work at a campus like Fareham College for the vacation?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Stubbington too small for you to travel to?

Not at all. Stubbington is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

How much does the work cost?

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

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Quoting for work in Stubbington

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Any access equipment needed
  • Backing rod, priming and other preparation

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • Access details, including height
  • The site address and postcode
  • What the building is and how it’s used
  • Any dates the work must fit around

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

On site: what to expect

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 typically takes half a day to a day per washroom, depending on the number of fittings. What matters most for a job in Stubbington is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Preparing the site

  • Share the asbestos register for older buildings
  • Flag any permit to work we will need
  • Move anything stored against the joints

Related advice

Aftercare for building managers

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

  • Clear standing water from shower floors where possible
  • Don’t leave an open joint at a basin or tray
  • Note failing joints building by building
  • Tell us about infection-control or permit rules before we quote

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Vanity carcasses that have swollen
  • Fittings that move too much to hold a bead

If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

What the job involves on each surface

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.
