Washroom sealing in Portchester

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a morning or so for a small washroom, longer where showers and changing rooms are included. For a site in Portchester, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Preparing the site

  • Send your site hours and access windows
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Washroom sealing in Portchester

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. If you’re dealing with failed joints along IPS and cubicle panels and urinal joints that look unhygienic, we can help, on IPS panels and cubicles, urinals and WCs and kitchens and tea points alike. Most enquiries from Portchester start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Jobs in a smaller place such as Portchester are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sets the cost

Before we quote, we look at:

  • Any access equipment needed
  • Location, for remote and island sites
  • The product specified
  • Induction, permit and paperwork requirements

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • Anything awkward about access or site hours

To get a fixed quote, call 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Water escaping beneath the floor rather than through a joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Vanity carcasses that have swollen

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

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

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What happens if it’s left?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

What you get with us

  • 12 months’ guarantee on every job
  • Colour agreed before work starts
  • Joints cleaned back to sound surfaces
  • One number for every site we cover

Keeping Portchester washrooms open while we work

The sea is no more than about 1 mile from Portchester, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. The area within 2 miles of Portchester holds a number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.

En suites at hotels like Portsmouth Marriott Hotel (to the east of Portchester) are cleaned daily, which wears silicone over time. For a college such as St Vincent College, 2.8 miles south of Portchester, half-term and summer give the windows for washroom work. Units at estates like Castle Trading Estate, under half a mile north of Portchester, have welfare blocks whose showers and toilets see shift after shift.

Portchester is about 3 miles north-east of Gosport, in Hampshire. Businesses, contractors and managing agents in Portchester use us for work on washrooms and wet areas, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Portchester.

Common questions from Portchester clients

Do you take on work at healthcare sites like Queen Alexandra Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work around term dates at a campus such as University of Portsmouth - North Zone?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

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. If anything suspect turns up, we stop until it’s tested.

Do you have public liability insurance?

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

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.

Can you reseal washrooms in healthcare buildings?

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

What the job involves on each surface

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.

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements and any permits the site uses.
