Washroom sealing across Crockerhill

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Rural sites near Crockerhill may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Point out any areas we must not close
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

About our washroom sealing in Crockerhill

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, 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. Site teams most often ask us about shower tray joints that have opened up and washrooms that look worn because of the sealant, on accessible toilets and changing rooms, IPS panels and cubicles and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crockerhill, that means joint design, primers and backing rod as standard.

Smaller places such as Crockerhill still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Why it’s worth doing now in Crockerhill

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Older rural buildings around Crockerhill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we can’t put right

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Loose panels, vanity units or tiles, which need fixing first
  • Swollen or delaminated boards behind panels or vanity tops
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.

Where we work in Crockerhill

Questions about Crockerhill

Is a hospital such as Chichester Centre somewhere you can work?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Crockerhill off your patch?

Not at all. Crockerhill is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

When can showers be used after new sealant?

The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Cost factors for washrooms and wet areas

Before we quote, we look at:

  • Working within restricted access windows
  • The site’s rules and procedures
  • Access and working height
  • Whether old sealant has to be cut out first

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • Any dates the work must fit around

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or send details through our quote form.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
