What the job involves on each surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath and point it out if water appears to rise from below.

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.

How we handle washroom sealing in Great Canfield

In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. Most enquiries involve users noticing mouldy joints and discoloured joints around urinals and WC pans, on kitchens and tea points, IPS panels and cubicles and urinals and WCs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Great Canfield, preparation and product choice get the time they need.

In and around smaller places like Great Canfield, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Wet areas in Great Canfield’s workplaces

Great Canfield is about 29 miles from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Units at estates like Blue Gates Industrial Park (to the north of Great Canfield) have welfare blocks whose showers and toilets see shift after shift. For a hall at a building such as Parish Church of St Mary, resealing the kitchen and toilets can be fitted between bookings.

Great Canfield is about 3 miles south-west of Great Dunmow, in Essex.

Maintenance after handover

For the best life from the joints:

  • Add sealant joints to planned maintenance checks
  • Make sure washroom ventilation is running
  • Keep a record of which washrooms need attention
  • Clear standing water from shower floors where possible

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

Great Canfield: questions and answers

Is Great Canfield too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will the toilets in our Great Canfield building be out of use?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How much does the work cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Commercial clients in Great Canfield

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Why it’s worth doing now in Great Canfield

Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and your cleaning team stops chasing it. Around Great Canfield, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Diagnose, treat, 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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Great Canfield can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  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.
