Washroom sealing in Widmore

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Tell us about infection-control or permit rules before we quote
  • Don’t leave trays and floors sitting wet
  • Keep a record of which washrooms need attention
  • Add sealant joints to planned maintenance checks

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

Washroom sealing for commercial buildings in Widmore

Whether it’s a single toilet block in Widmore or a programme across several buildings, we work the same way: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. If you’re dealing with a new bead over an old one coming away and black mould inside silicone joints that cleaning can’t shift, we can help, whatever the surface. A single leaking joint is often how a building in Widmore first comes to us: we look at the rest while we’re there and tell you what we find.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.

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 spell out the cover before we begin.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What we can’t put right

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

  • Water from plumbing, not from a joint
  • Swollen or delaminated boards behind panels or vanity tops
  • Failed tanking beneath a wet-room floor or behind tiles

If you are not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Keeping Widmore washrooms open while we work

A 2-mile radius around Widmore takes in a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.

Colleges such as Bromley College (1.1 miles south-west of Widmore) have toilets, changing rooms and catering kitchens that can be resealed around term dates. For a campus such as University of Greenwich - Avery Hill, which lies north of Widmore, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Widmore is about 1 mile east of Bromley, in Greater London. If you are looking for washroom sealing in Widmore, we can help. Our Greater London coverage takes in 764 places, from busy centres to rural villages. We also cover London, some 9 miles away.

Your questions answered

Do hotels near Widmore have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Could you schedule work at a campus like University of Greenwich - Avery Hill for the vacation?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit usually takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we will set out a timescale with the quote.

What do you charge?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

How do we ask for a quote?

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

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote.

Do you cover Widmore?

Yes. We take on work across Widmore.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Access and working height

Pricing washrooms and wet areas depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • The postcode of the building
  • Access details, including height
  • The product your specification calls for
  • Whether the building will be occupied during the work

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.

How a job runs

In a busy building, 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. In Widmore, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send details through our quote form.

Related advice

Common problems we fix in Widmore

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old so it peels away quickly.

Typical triggers for a call:

  • Resealing that didn’t last because the old bead stayed
  • Failed sealant behind washroom basins
  • Shower tray joints that have opened up
  • Complaints from staff, guests or users about tired washrooms

Staff changing rooms and patient toilets at places like Sloane Hospital (to the west of Widmore) need cleanable, sound silicone.
