Washroom sealing across Beckton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Washroom sealing in Beckton

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. Most enquiries involve sealant stained black around basins and showers and failed sealant in a tea point or staff kitchen, across urinals and WCs, showers, trays and wet room floors and vanity units and basins. A single leaking joint is often how a building in Beckton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you.

Whoever the client is, the cover is the same: 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.

Washroom sealing in Beckton: the local picture

There are a good number of hotels within about 2 miles of Beckton. 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. Busy London buildings need some toilets open at all times, which is why the work is split into phases agreed in advance.

For a site such as Cygnet Hospital Beckton, under half a mile to the south-west of Beckton, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For a campus such as University of East London, 0.5 miles to the south of Beckton, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Beckton is about 1 mile south-east of East Ham, in Greater London. We cover Beckton and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, Beckton among them. For work in that direction, see our London page (7 miles or so).

If you need washroom sealing in E6 and E16, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Trader Road, Eastbury Road and Frobisher Road, and sites on any of them can send details for a fixed quote. You’ll find Beckton on or near the A13, so getting applicators and materials to site is simple. Sites close to Beckton are covered too, including Cyprus (1 mile south-west), North Woolwich (1 mile south-west), East Ham (1 mile north-west), Royal Docks (1 mile south-west) and Wallend (1 mile north). Nearby towns on our patch include London (7 miles west), City of Westminster (9 miles west), Marylebone (9 miles west), Kensington (12 miles west), St Pancras (8 miles west) and Shoreditch (6 miles west).

How the quote is worked out

These are the things that shape the price:

  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Working within restricted access windows
  • Distance, for remote addresses

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • What the building is and how it’s used

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Share your site rules when you send details
  • Keep extract fans working and vents clear
  • Report split joints at trays and basins early
  • Brief cleaning staff to treat joints gently

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

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:

  • Condensation from failed extract fans
  • Vanity carcasses that have swollen
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

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

What we seal

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

When to call us in Beckton

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting, and they stain, crack or wash out.

Look out for the following:

  • Split or peeling sealant at shower trays
  • Sealant stained black around basins and showers
  • Discoloured joints around urinals and WC pans
  • Failed sealant in a tea point or staff kitchen

For an occupier at a site such as London Industrial Park (under half a mile north of Beckton), the canteen and welfare facilities need cleanable joints as much as any office.

What to look for in a quote

  • Their public liability cover
  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Questions about Beckton

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. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

Could you schedule work at a campus like University of East London for the vacation?

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

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Who decides which product is used?

The specification comes first, if there is one. 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 strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.

Do you guarantee washroom sealing?

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

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  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. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

Ask for a quote
