Signs you need washroom sealing in Colden Common

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water, and they stain, crack or wash out.

Look out for the following:

  • Urinal joints that look unhygienic
  • Washrooms that look worn because of the sealant
  • Sealant laid over old silicone and now peeling
  • Failed joints along IPS and cubicle panels

In a centre such as Cannons Retail Park, 2.7 miles south-west of Colden Common, public washrooms are resealed a block of facilities at a time.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing
  • The named product and why it was chosen
  • Their public liability cover

If you’re dealing with users noticing mouldy joints and open joints at the base of cubicle panels, we can put it right, whatever the surface. Whoever orders the work in Colden Common, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around Colden Common, washroom work normally comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Joint width, depth and condition
  • The site’s rules and procedures
  • Travel to remote or island sites

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Why act early in Colden Common

Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. In a smaller place such as Colden Common, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

A quote for washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.

What the job involves on each surface

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Fittings that move too much to hold a bead
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Vanity carcasses that have swollen

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Where we work in Colden Common

  • Urinals and WCs
  • Kitchens and tea points

Advice

Your questions answered

Must a hotel around Colden Common close while you work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Is Colden Common too far out for you?

Not at all. Colden Common is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will you quote for a small job?

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