Washroom sealing near Horseman Side

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

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Washroom sealing in Horseman Side, 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. Product and method follow how hard each area is used and cleaned. We work on urinals and WCs, vanity units and basins and accessible toilets and changing rooms, and the usual reasons a site gets in touch are gaps where vanity tops meet the wall and failed joints along IPS and cubicle panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Horseman Side it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Community buildings around smaller places like Horseman Side have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Building owners and contractors get the same cover: 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.

What sealant work can’t fix

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

  • A dripping waste or valve behind a panel
  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes

If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.

What we seal

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

Maintenance after handover

After handover, these steps help:

  • Note failing joints building by building
  • Leave signs up until the cure time is over
  • Add sealant joints to planned maintenance checks
  • Make sure washroom ventilation is running

Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again and signage stays in place until that time.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Washroom sealing around Horseman Side: how the place shapes the job

Questions about Horseman Side

Can you work on a hospital site such as Suttons Manor Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Could you schedule work at a campus like Havering Technical College for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Can you clean the mould off instead of resealing?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Include photos or drawings if you have them.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Common problems we fix in Horseman Side

Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.

Typical triggers for a call:

  • A new bead over an old one coming away
  • Mould spotting along silicone joints
  • Failed sealant in a tea point or staff kitchen
  • Gaps where vanity tops meet the wall

At a college such as Havering Technical College, which lies south of Horseman Side, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Horseman Side, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
