About our washroom sealing in Great Bromley

In a commercial washroom, sealant is usually the first thing to wear out. 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. We strip it out and lay new anti-mould sanitary silicone. If you have split or peeling sealant at shower trays and panel joints letting water behind, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Great Bromley, preparation and product choice get the time they need.

Smaller places such as Great Bromley 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.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • A room that stays damp because ventilation isn’t working
  • Fittings that move too much to hold a bead
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Surfaces we seal

  • Showers, trays and wet room floors
  • Accessible toilets and changing rooms
  • Urinals and WCs
  • IPS panels and cubicles
  • Vanity units and basins
  • Kitchens and tea points

What sets the cost

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • Access and working height
  • The total length or number of joints
  • The product specified

Pricing washrooms and wet areas depends on quantities, condition and access. Call for a quote.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Your programme or deadline
  • Photos of the joints, close up and from further back

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or use the quote form to discuss it first.

For a school such as St George's Church of England Primary School, washroom and kitchen sealant can be renewed around term dates. Welfare facilities in units on estates such as Martells Industrial Estate, 2.5 miles to the north-west of Great Bromley, have showers, toilets and kitchens with sealant that works hard.

After the work

Keep the joints in good shape with a few simple steps:

  • Respect the cure time before reopening each room
  • Avoid scourers and harsh descalers on silicone
  • Share your site rules when you send details
  • Act on the first split you see at a shower tray

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

What we’re called out for in Great Bromley

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Things that usually lead to an enquiry:

  • Sealant stained black around basins and showers
  • Open joints along basins and vanity units
  • Resealing that didn’t last because the old bead stayed
  • Shower tray joints that have opened up

Clinical washrooms at sites like Colchester Hospital, 5.6 miles west of Great Bromley, are scheduled with the ward so the room is out of use for as little time as possible.

  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?
  • Will CSCS-carded applicators be on site?

Common questions from Great Bromley clients

Is Great Bromley too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like University of Essex for the vacation?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

How do I request 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 photographs and a postcode.

Do you use special sealant for toilets and showers?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Related advice

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
