Need washroom sealing in West Kensington?

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

What happens if it’s left?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Washroom sealing in West Kensington: the local picture

West Kensington has plenty of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest. In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time.

For a college such as St Mellitus Theological College, which lies east of West Kensington, half-term and summer give the windows for washroom work. For a site such as Charing Cross Hospital, 0.6 miles to the south-west of West Kensington, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For a campus such as University of Westminster, which lies north of West Kensington, showers in residences and washrooms in teaching blocks can be programmed around term dates.

West Kensington is about 1 mile south of Kensington, in Greater London. We send applicators to West Kensington for washrooms and wet areas, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places.

Quoting for work in West Kensington

To price the job, we consider:

  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • The total length or number of joints

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • The product your specification calls for
  • When you need the work done

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call 01277 525 020 or email the details over.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes half a day to a day per washroom, depending on the number of fittings. In West Kensington, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Point out any areas we must not close

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Related advice

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Surface by surface

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.

West Kensington: questions and answers

Is a hospital such as Charing Cross Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you cover West Kensington?

Yes. Sites across West Kensington are covered.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Loose panels, vanity units or tiles, which need fixing first
  • Panel boards already damaged by water
  • Condensation from failed extract fans

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
