FAQs: Tendring

What site paperwork comes with a job in Tendring?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Tendring too small for you to travel to?

Not at all. Tendring is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we will set out a timescale with the quote.

Is old silicone taken out first?

We strip every bit of the failed bead and wipe away the residue before resealing. That’s what makes the new joint last.

Can washrooms stay open while you work?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

About our washroom sealing in Tendring

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and what we are called in for most is washrooms that look worn because of the sealant and split or peeling sealant at shower trays. Looking for mastic applicators who cover Tendring? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Halls and community buildings near places like Tendring are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

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.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A room that stays damp because ventilation isn’t working
  • Panel boards already damaged by water
  • Failed tanking beneath a wet-room floor or behind tiles

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Where we work in Tendring

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Rural sites near Tendring may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Agree which areas must stay open
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Keeping Tendring washrooms open while we work

Tendring lies roughly 58 miles out from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time.

For a hall at a building such as Church of St Edmund, resealing the kitchen and toilets can be fitted between bookings. For buildings on a site such as Oak Business Park, 2.2 miles east of Tendring, washrooms and tea points can be resealed in phases through the working week. For a school such as Tendring Primary School, washroom and kitchen sealant can be renewed around term dates.

Tendring is about 5 miles north of Clacton-on-Sea, in Essex. Any commercial site in Tendring is covered, whether it’s a single job or part of a planned programme.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Why it’s worth doing now in Tendring

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Halls, stores and units around places like Tendring may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why us?

  • A fixed quote before work starts
  • Constructionline member for supplier checks
  • Matching to RAL references, product permitting
  • Specification-led, product-correct work

Keeping the joints sound

To get the most from the new sealant:

  • Share your site rules when you send details
  • Keep extract fans working and vents clear
  • Don’t leave an open joint at a basin or tray
  • Brief cleaning staff to treat joints gently

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

What the job involves on each surface

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.
