Washroom sealing for businesses in Gordon Hill

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Quoting for work in Gordon Hill

We price every job individually. The things that drive the figure:

  • Quantities, in metres or numbers
  • The product specified
  • Location, for remote and island sites
  • The site’s rules and procedures

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 requirements come into it too.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • The product your specification calls for
  • The site address and postcode

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

About our washroom sealing in Gordon Hill

Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, 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 along basins and vanity units and discoloured joints around urinals and WC pans, on accessible toilets and changing rooms, vanity units and basins and urinals and WCs. One point of contact handles commercial sealant work in Gordon Hill from the first photos to the final walk-round, for single jobs and planned programmes alike.

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, so staff and visitors can always find an open washroom.

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’re clear about what is covered before work starts.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Condensation from failed extract fans
  • Fittings that move too much to hold a bead
  • Swollen or delaminated boards behind panels or vanity tops

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

Joints and surfaces we work on

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

How the job changes by surface

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.

Kitchens and tea points

Kitchen work can be phased around service. Your site hours and access windows set the timing.

What we are called out for in Gordon Hill

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and say if it needs a plumber or another trade.

Things that typically lead to an enquiry:

  • Discoloured joints around urinals and WC pans
  • Split or peeling sealant at shower trays
  • Panel joints letting water behind
  • Open joints along basins and vanity units

Healthcare washrooms on sites such as St Michael's Community Hospital, under half a mile to the south-east of Gordon Hill, are resealed area by area, under the site’s own infection-control rules.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • What level of public liability insurance do they hold?
  • Who will actually carry out the work
  • Health and safety accreditation such as CHAS

Questions about Gordon Hill

Do you take on jobs in Gordon Hill where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

Can work in a care setting near Gordon Hill go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is Gordon Hill in your area?

Yes. We cover Gordon Hill, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email the details over.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Can you clean the mould off instead of resealing?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Gordon Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Have the specification and drawings to hand
  • Point out any areas we must not close
  • Arrange parking or a loading space
