About our washroom sealing in Holton

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, 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. If you are dealing with sealant laid over old silicone and now peeling and failed sealant in a tea point or staff kitchen, 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: in Holton, that means joint design, primers and backing rod as standard.

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

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

FAQs: Holton

Can you work on a hospital site such as Slade Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Holton off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Can washrooms stay open while you work?

We phase it so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.

Can you reseal washrooms in healthcare buildings?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote before we start.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Smaller jobs around Holton can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Point out any areas we must not close

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

When to call us in Holton

Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.

If one of these sounds familiar, it’s time for a closer look:

  • Discoloured joints around urinals and WC pans
  • Black mould inside silicone joints that cleaning can’t shift
  • Sealant lifting along a tray edge
  • Failed sealant behind washroom basins

Staff changing rooms and patient toilets at places like Slade Hospital, 2.8 miles to the west of Holton, need cleanable, sound silicone.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Commercial clients in Holton

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

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

When to bring in a 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.

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.

What the job involves on each surface

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. Loose panels are flagged before any sealant goes on.

Keeping Holton washrooms open while we work

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Water escaping beneath the floor rather than through a joint
  • Vanity carcasses that have swollen
  • Fittings that move too much to hold a bead

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.

Where we work in Holton

  • Vanity units and basins
  • Showers, trays and wet room floors
