How we handle washroom sealing in Tonge

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. If you have kitchen worktop joints that can’t be kept clean and mould spotting along silicone joints, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Tonge is the same: the right product in a properly prepared joint.

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

The 12-month guarantee is for workmanship rather than 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.

Aftercare for building managers

To get the most from the new sealant:

  • Photograph and log failed joints across the estate
  • Mention any site permits or estates rules at quote stage
  • Add sealant joints to planned maintenance checks
  • Make sure washroom ventilation is running

If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, regular checks keep small problems small.

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

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions about Tonge

Would you work within a site like Sittingbourne Memorial Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can work at a site such as KITE College fit around teaching?

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.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Do you use special sealant for toilets and showers?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

What sets the cost

We price every job individually. The main factors are:

  • Working within restricted access windows
  • Access and working height
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first

There’s no price list, since every building and every scope is different. Call for a quote.

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists
  • Any dates the work must fit around

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

When to call us in Tonge

Panels and vanity units move slightly in use and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

Typical triggers for a call:

  • Urinal joints that look unhygienic
  • Failed sealant behind washroom basins
  • Sealant stained black around basins and showers
  • Failed sealant in a tea point or staff kitchen

Colleges such as KITE College, 1.5 miles west of Tonge, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Comparing quotes

  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Water escaping beneath the floor rather than through a joint
  • A room that stays damp because ventilation isn’t working
  • Fittings that move too much to hold a bead

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. For a building around Tonge, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We inspect each washroom and record the joints to be resealed.
  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. Each area is handed back when ready.

Getting the site ready

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Warn occupants and staff about the work
