Washroom sealing across Deerton Street

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Your questions answered

Will the toilets in our Deerton Street building be out of use?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

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

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Do you cover Deerton Street?

Yes. Deerton Street falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email us.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Do you work in hospitals, clinics and care homes?

We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

Do you phase washroom resealing?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time, then we move on.

Washroom sealing in Deerton Street, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used. Most enquiries involve failed sealant in a tea point or staff kitchen and panel joints letting water behind, across showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms. A single leaking joint is often how a building in Deerton Street first comes to us: we look at the rest while we’re there and tell you what we find.

Halls and community buildings near places like Deerton Street are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Common problems we fix in Deerton Street

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

Look out for the following:

  • Failed sealant behind washroom basins
  • Sealant laid over old silicone and now peeling
  • Sealant lifting along a tray edge
  • Sealant stained black around basins and showers

Halls linked to places like Church of St Mary host groups all week, which is hard on kitchen and toilet sealant.

What your quote should include

  • Their public liability cover
  • Whether primer will be used where the manufacturer specifies it
  • The named product and why it was chosen
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Washroom sealing around Deerton Street: what changes locally

Deerton Street is within about 2 miles of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. Deerton Street is about 41 miles from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

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

What sets the cost

Before we quote, we look at:

  • Working within restricted access windows
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What we need to price the job

We can often quote from photographs and a few details. It helps to include:

  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • Where the site is, with the postcode
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. For a building around Deerton Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
