Washroom sealing in Little Dunmow

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you have split or peeling sealant at shower trays and urinal joints that look unhygienic, we can put it right, on vanity units and basins, kitchens and tea points and showers, trays and wet room floors alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Little Dunmow, preparation and product choice get the time they need.

Jobs in a smaller place such as Little Dunmow are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Your questions answered

Will all the washrooms in our Little Dunmow building be closed at once?

Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Is hospital work, at somewhere like Braintree Community Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you need to remove the old sealant?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Commercial clients in Little Dunmow

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Several jobs near Little Dunmow can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

What we need from you

Advice

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Leaks through tanking or membranes below the finishes
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first

If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

Surface by surface

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.

Signs you need washroom sealing in Little Dunmow

Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.

Things that usually lead to an enquiry:

  • Gaps where vanity tops meet the wall
  • A new bead over an old one coming away
  • Mould spotting along silicone joints
  • Users noticing mouldy joints

At a school such as The Flitch Green Academy, changing rooms and kitchens need cleanable joints as much as the toilets.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Whether their applicators hold CSCS cards
  • Whether old or failed sealant will be cut out, not overlaid
  • Their plan for phasing and protecting the area

Our contractor checklist

Why deal with it now?

Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Small buildings around Little Dunmow suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why us?

  • Colour agreed before work starts
  • Sealing commercial buildings since 2005
  • Joints cleaned back to sound surfaces
  • Matching to RAL references, product permitting
