FAQs: Heath Park

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

Is a hospital such as Victoria Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you use special sealant for toilets and showers?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.

Do you do washroom sealing in healthcare settings?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Do you have public liability insurance?

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

Washroom sealing in Heath Park, done properly

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. We work on IPS panels and cubicles, urinals and WCs and showers, trays and wet room floors, and the failures we’re asked to look at most are users noticing mouldy joints and resealing that didn’t last because the old bead stayed. Whether you call it commercial sealant work, mastic application or joint sealing, in Heath Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What the job involves on each surface

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements as well as site permits.

Washroom sealing in Heath Park: the local picture

There are several hotels within about 2 miles of Heath Park. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available. A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time.

Colleges such as New City College, 1 mile north-east of Heath Park, have toilets, changing rooms and catering kitchens that can be resealed around term dates. Healthcare estates like Victoria Hospital (to the north-west of Heath Park) expect contractors to follow their permits and cleaning rules in every washroom.

Heath Park is about 1 mile east of Romford, in Greater London. Heath Park sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Greater London, 764 places are covered, Heath Park among them. Sites around London have their own page, roughly 14 miles from Heath Park.

If you need washroom sealing in RM11, RM1 and RM2, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Moss Lane, Park Lane and Manor Road are within our area. If your building is just outside Heath Park, we cover Ardleigh Green (1 mile north-east), Hornchurch (1 mile south-east), Emerson Park (1 mile east), Gidea Park (1 mile north) and Gallows Corner (1 mile north). Bigger towns within reach include London (14 miles west), St Pancras (14 miles west), Shoreditch (12 miles west), Walthamstow (10 miles west), Hoxton (13 miles west) and Whitechapel (12 miles west).

After the work

Keep the joints in good shape with a few simple steps:

  • Avoid scourers and harsh descalers on silicone
  • Include joints in routine washroom inspections
  • Tell us about infection-control or permit rules before we quote
  • Act on the first split you see at a shower tray

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Common problems we fix in Heath Park

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead, so it soon lets go.

Common reasons buildings call us in:

  • Panel joints letting water behind
  • Black mould inside silicone joints that cleaning can’t shift
  • Open joints along basins and vanity units
  • Washrooms that look worn because of the sealant

Toilets at places like The Mercury Mall, 0.8 miles north-west of Heath Park, are cleaned constantly, so silicone needs to be sound and smooth.

What to look for in a quote

  • How joint depth will be controlled
  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • Their public liability cover

How to choose a sealant contractor

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. Planning a London job such as one in Heath Park starts with access. Give us the hours we can be on site and we will schedule to suit.

  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. 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.

What we need from you

  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open

What sets the cost

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Quantities, in metres or numbers
  • Location, for remote and island sites

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Anything awkward about access or site hours
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or email us.
