About our washroom sealing in Gallows Corner

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. The enquiries we see most involve open joints at the base of cubicle panels and resealing that didn’t last because the old bead stayed, on IPS panels and cubicles, showers, trays and wet room floors and kitchens and tea points. For commercial sealant work in Gallows Corner, you deal with one contact from quote to sign-off, whether it’s one building or several.

In Gallows Corner, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions about Gallows Corner

Can you cope with the access rules in a London building?

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Must a hotel around Gallows Corner close while you work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Leave it or put it right?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Why us?

  • One number for every site we cover
  • Public liability insurance in place
  • Matching to RAL references, product permitting
  • Specification-led, product-correct work

How the job changes by surface

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.

IPS and cubicle panels

Panels flex slightly in use, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Condensation from failed extract fans
  • Swollen or delaminated boards behind panels or vanity tops
  • Water from plumbing, not from a joint

If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

Joints and surfaces we work on

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

Washroom sealing in Gallows Corner: the local picture

A number of hotels sit less than 2 miles from Gallows Corner. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping. London offices and hotels usually can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager.

For a store at a site such as Rom Valley Retail Park, 2 miles to the south-west of Gallows Corner, the staff room and customer toilets can be resealed in quiet periods. For a hotel such as Park Hotel Essex, 0.6 miles south-west of Gallows Corner, resealing en suites a few rooms at a time keeps the rest available. Clinical washrooms at sites like Victoria Hospital, 1.2 miles south-west of Gallows Corner, are scheduled with the ward so the room is out of use for as little time as possible.

Gallows Corner is about 2 miles north-east of Romford, in Greater London. Any commercial site in Gallows Corner is covered. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Sites around London have their own page, roughly 15 miles from Gallows Corner.

If you need washroom sealing in RM3, RM2 and RM11, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Just outside Gallows Corner, we also work in Gidea Park (1 mile west), Ardleigh Green (1 mile south), Harold Wood (1 mile east), Heath Park (1 mile south) and Emerson Park (1 mile south-east).

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Report split joints at trays and basins early
  • Inspect washroom sealant regularly
  • Keep a record of which washrooms need attention
  • Leave signs up until the cure time is over

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

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.

Quoting for work in Gallows Corner

To price the job, we consider:

  • Backing rod, priming and other preparation
  • The product specified
  • How much existing material needs removing
  • The total length or number of joints

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or email the details over.
