About our washroom sealing in Canewdon

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. We work on urinals and WCs, vanity units and basins and showers, trays and wet room floors, and the failures we’re asked to look at most are discoloured joints around urinals and WC pans and black mould inside silicone joints that cleaning can’t shift. A single leaking joint is often how a building in Canewdon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Canewdon 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.

A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we will arrange a return visit.

Questions we’re asked in Canewdon

Is a hospital such as Rochford Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Do you do washroom sealing in healthcare settings?

We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

Can one quote cover more than one building?

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

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Will all the toilets be closed at once?

Only the area we’re working in is closed. Rooms go back into use once the sealant has cured and we start the next.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Why it’s worth doing now in Canewdon

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Converted and older buildings near places like Canewdon tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

What you get with us

  • Products installed to the manufacturer’s instructions
  • Coloured sealants to suit the setting, where available
  • Old sealant cut out, never sealed over
  • Over 20 years of commercial sealing

Read what affects the cost and our accreditations and insurance.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • How much there is to seal

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • Any specification or named product
  • Asbestos survey details if the building is older

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, ring 01277 525 020 or email a schedule or drawings.

Aftercare for building managers

To get the most from the new sealant:

  • Include joints in routine washroom inspections
  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building
  • Tell us about infection-control or permit rules before we quote

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Canewdon can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. The failed silicone is stripped and every face scraped clean of residue.
  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. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

Advice

Keeping Canewdon washrooms open while we work

Central London is about 37 miles from Canewdon, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

For a school such as King Edmund School, washroom and kitchen sealant can be renewed around term dates. Halls linked to places like Church of St Nicholas host groups all week, which is hard on kitchen and toilet sealant. On a healthcare site such as Rochford Hospital (2.8 miles south-west of Canewdon), washroom work starts with the infection-control team’s sign-off.
