Your questions answered

Is a smaller place like Great Oakley outside your area?

No. Places such as Great Oakley are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What paperwork can you provide for a job in Great Oakley?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Will cleaning remove black mould from sealant?

Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

Which silicone is right for commercial washrooms?

An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Washroom sealing in Great Oakley, done properly

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. Site teams most often ask us about urinal joints that look unhygienic and resealing that didn’t last because the old bead stayed, on IPS panels and cubicles, urinals and WCs and vanity units and basins. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Great Oakley, that means joint design, primers and backing rod as standard.

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

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

Looking after the joints

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

  • Keep a record of which washrooms need attention
  • Avoid scourers and harsh descalers on silicone
  • Leave signs up until the cure time is over
  • Squeegee showers and trays after busy periods

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface and give mould a start.

Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Smaller jobs around Great Oakley can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  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. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Move anything stored against the joints
  • Tell us which areas need to stay in use
  • Arrange parking or a loading space

Honest limits

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • A room that stays damp because ventilation isn’t working
  • A dripping waste or valve behind a panel
  • Water escaping beneath the floor rather than through a joint

If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

Commercial washrooms in Great Oakley

Great Oakley lies within about 2 miles of the sea, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. At about 62 miles from central London, Great Oakley is within reach of the capital. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

Halls linked to places like Parish Church of All Saints host groups all week, which is hard on kitchen and toilet sealant. Office washrooms on sites such as Oak Business Park (to the south-west of Great Oakley) are in use all working day, so resealing is phased to keep some open.

What happens if it’s left?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Older rural buildings around Great Oakley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Pricing washrooms and wet areas depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

  • Work to your specification and the manufacturer’s guidance

Doing it in-house

Paperwork matters too. 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.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
