Washroom sealing for Althorne sites

Washroom sealing for commercial buildings in Althorne

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. Where food contact is possible, we use a hygienic, food-safe grade. Most enquiries involve stained sealant around pans and urinals and stained or open joints at kitchen sinks and worktops, across IPS panels and cubicles, kitchens and tea points and accessible toilets and changing rooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Althorne, that means joint design, primers and backing rod as standard.

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

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What happens if it’s left?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. For buildings around smaller places like Althorne, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Matching to RAL references, product permitting
  • CHAS accredited
  • A range of standard colours, depending on the product
  • 12 months’ guarantee on every job

Take a look at how commercial sealant jobs are priced and our accreditations.

Cost factors for washrooms and wet areas

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Whether the work must be split into stages
  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • Access details, including height
  • Clear photographs of the problem areas
  • The site address and postcode

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email the details over.

Sanitary sealant for Althorne buildings

Althorne sits close to the coast, within about 3 miles, and seaside hospitality usually has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. Althorne lies roughly 38 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

Office washrooms on sites such as Red Lions Business Centre, 1.2 miles north-west of Althorne, are in use all working day, so resealing is phased to keep some open. For a hall at a building such as Parish Church of St Andrew, resealing the kitchen and toilets can be fitted between bookings.

Althorne is about 5 miles north-east of Rochford, in Essex. Businesses, contractors and managing agents in Althorne can call on us for washrooms and wet areas. Our Essex coverage takes in 644 places, large and small. Sites around London have their own page, about 38 miles away.

We take on washrooms and wet areas across the CM3 postcode area, whatever the building. If your site is on Station Road, Fambridge Road and Chestnut Farm Drive or close by, send details and we will quote for washrooms and wet areas. Close to Althorne, our area also takes in Latchingdon (2 miles north-west), Mayland (2 miles north), Ostend (2 miles east), Maylandsea (2 miles north) and Creeksea (2 miles south-east). A short drive away, we cover Chelmsford (13 miles north-west), Basildon (14 miles south-west), Maldon (6 miles north-west), Canvey Island (12 miles south-west), Billericay (14 miles west) and Rayleigh (8 miles south-west).

FAQs: Althorne

What documents will you need to give us for a job in Althorne?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will the toilets in our Althorne building be out of use?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Do you take on small jobs?

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

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

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

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Althorne can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Let us know about inductions and permits
  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use
