About our washroom sealing in Hacton

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. Most enquiries involve sealant lifting along a tray edge and washrooms that look worn because of the sealant, across showers, trays and wet room floors, IPS panels and cubicles and vanity units and basins. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hacton is the same: the right product in a properly prepared joint.

Building managers in Hacton typically need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.

Every job we finish is backed by a 12-month workmanship guarantee, in Hacton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Hacton

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Joint width, depth and condition
  • How much there is to seal
  • How accessible the joints are
  • Site requirements such as inductions and permits

Pricing washrooms and wet areas depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas
  • How the joints are reached, and at what height
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

What happens if it’s left?

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. In Hacton, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

What you get with us

  • A fixed quote before work starts
  • Standard and matched colours in many product ranges
  • Commercial sealant work since 2005
  • A Constructionline member, so easy to vet

Take a look at our cost guide or how we’re accredited.

Aftercare for building managers

For the best life from the joints:

  • Share your site rules when you send details
  • Make sure washroom ventilation is running
  • Add sealant joints to planned maintenance checks
  • Avoid scourers and harsh descalers on silicone

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly.

What we seal

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

Common questions from Hacton clients

Will you plan work around the academic year at somewhere like New City College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

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.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Will cleaning remove black mould from sealant?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Busy facilities in and around Hacton

London offices and hotels typically can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team.

Hotels such as The Manor Hotel & Restaurant (to the south of Hacton) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Clinical washrooms at sites like Queens Hospital (to the north-west of Hacton) are scheduled with the ward so the room is out of use for as little time as possible. Welfare facilities in units on estates such as Deans Trading Estate (1.4 miles south-west of Hacton) have showers, toilets and kitchens with sealant that works hard.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
