Washroom sealing in Hemsted, done properly

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you have kitchen worktop joints that can’t be kept clean and black mould inside silicone joints that cleaning can’t shift, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hemsted it comes down to the same thing: the right product in a properly prepared joint.

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

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks through tanking or membranes below the finishes
  • Hollow tiles or loose panels behind the joint
  • Panel boards already damaged by water

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Surfaces we seal

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

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Avoid scourers and harsh descalers on silicone
  • Share your site rules when you send details
  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

When to call us in Hemsted

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

Things that typically lead to an enquiry:

  • Panel joints letting water behind
  • Failed sealant in a tea point or staff kitchen
  • Stained sealant around pans and urinals
  • Users noticing mouldy joints

For a school such as Stowting Church of England Primary School, washroom and kitchen sealant can be renewed around term dates.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Who will actually carry out the work
  • Whether primer will be used where the manufacturer specifies it
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

Questions about Hemsted

What documents will you need to give us for a job in Hemsted?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Hemsted too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How much does the work cost?

We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Quoting for work in Hemsted

To price the job, we consider:

  • How much existing material needs removing
  • The size and state of each joint
  • Whether the work must be split into stages
  • Any access equipment needed

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Access details, including height
  • The asbestos register, for older buildings
  • The product your specification calls for
  • The type of building and who uses it

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or email us.

On site: what to expect

We follow your site rules from the start: 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, and each area is checked before we leave it. Rural sites near Hemsted may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work
  • Arrange parking or a loading space

Advice

General trades versus a specialist

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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
