About our washroom sealing in Fleet

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. 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 have black mould inside silicone joints that cleaning can’t shift and open joints at the base of cubicle panels, we can put it right, on urinals and WCs, kitchens and tea points and accessible toilets and changing rooms alike. Most enquiries from Fleet start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For hospitality businesses in towns like Fleet, sealed joints in kitchens and toilets help keep surfaces easy to clean. Environmental health officers look at cleanability, and a sound sanitary or hygienic sealant is part of that.

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 we are called out for in Fleet

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

Most enquiries start with one or more of the following:

  • Discoloured joints around urinals and WC pans
  • Gaps where vanity tops meet the wall
  • Mould spotting along silicone joints
  • Resealing that didn’t last because the old bead stayed

Toilets at places like Hart Shopping Centre (0.5 miles north of Fleet) are cleaned constantly, which is hard on silicone.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Common questions from Fleet clients

Can work at a site such as University for the Creative Arts fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is hospital work, at somewhere like Fleet Community Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. In a town such as Fleet, most jobs are single buildings. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email us.

Advice

Wet areas in Fleet’s workplaces

Central London is about 36 miles from Fleet. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available. There are three care or nursing homes within about 2 miles of Fleet. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs.

En suites at hotels like Lismoyne Hotel, 0.8 miles to the north-west of Fleet, are cleaned daily, which wears silicone over time. Clinical washrooms at sites like Fleet Community Hospital (to the north-west of Fleet) are scheduled with the ward so the room is out of use for as little time as possible.

Fleet is about 13 miles south-east of Reading, in Hampshire. Commercial clients in Fleet use us for work on washrooms and wet areas. 723 places across Hampshire fall within our area, Fleet among them. There’s a separate page for Reading, about 13 miles away.

If you need washroom sealing in GU51, GU52 and GU10, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Church Road, Durnsford Avenue and Hankins Court and the roads nearby. Access to Fleet is via the A323 and A3013 among other routes. Close to Fleet, our area also takes in Church Crookham (1 mile south-east), Crookham Village (1 mile west), Elvetham Heath (1 mile north-west), Dogmersfield (2 miles west) and Elvetham (2 miles north-west). Bigger towns within reach include Basingstoke (11 miles west), Farnborough (3 miles north-east), Aldershot (4 miles south-east), Alton (10 miles south-west), Yateley (4 miles north) and Tadley (14 miles north-west). Fleet ranks among the main centres of Hampshire, with offices, shops, schools and other public and commercial buildings, and we cover them all.

What we can’t put right

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

  • Water escaping beneath the floor rather than through a joint
  • Water from plumbing, not from a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can phone 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
  • Accessible toilets and changing rooms
  • Kitchens and tea points
  • IPS panels and cubicles
  • Vanity units and basins
  • Urinals and WCs

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Clean sealant with gentle products and a soft cloth
  • Keep washrooms out of use until we say the sealant has cured
  • Squeegee showers and trays after busy periods
  • Mention any site permits or estates rules at quote stage

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The total length or number of joints
  • How accessible the joints are
  • How much existing material needs removing
  • Backing rod, priming and other preparation

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
