Washroom sealing for Kensal Town sites

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

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Photograph and log failed joints across the estate
  • Brief cleaning staff to treat joints gently
  • Share your site rules when you send details
  • Add sealant joints to planned maintenance checks

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

About our washroom sealing in Kensal Town

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. If you’re dealing with failed sealant in a tea point or staff kitchen and resealing that didn’t last because the old bead stayed, we can help, whatever the surface. Looking for mastic applicators who cover Kensal Town? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Building managers in Kensal Town usually need some facilities open throughout. 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.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Sanitary sealant for Kensal Town buildings

In London buildings, toilets and showers generally need to stay partly open, so we phase the work core by core or floor by floor with the building manager. Plenty of hotels sit less than 2 miles from Kensal Town. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available.

Healthcare estates like St Charles' Hospital, less than half a mile west of Kensal Town, expect contractors to follow their permits and cleaning rules in every washroom. Toilets at colleges like Morley College London, under half a mile to the south-east of Kensal Town, take heavy use from students and staff alike. For a campus such as Imperial College London, 0.9 miles south-west of Kensal Town, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Kensal Town is about 2 miles north of Kensington, in Greater London. Anywhere in W10, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 764 places across Greater London fall within our area, Kensal Town among them.

Commercial sites across W10, W9 and W11 are covered for washrooms and wet areas. We cover commercial and managed buildings on Peach Road, Parry Road and Barlby Road.

Surface by surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath and point it out if water appears to rise from below.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

How the quote is worked out

To price the job, we consider:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Any access equipment needed

Pricing washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we need to price the job

However big the job, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email us with what you know.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Planning a London job such as one in Kensal Town starts with access. Give us the hours we can be on site and we will schedule to suit.

  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. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

What we need from you

  • Agree which areas must stay open
  • Warn occupants and staff about the work
  • Send any specification or drawings in advance

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Leaks through tanking or membranes below the finishes
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Swollen or delaminated boards behind panels or vanity tops

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

Where we work in Kensal Town

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

Common questions from Kensal Town clients

Is a hospital such as St Charles' Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Will our hotel in Kensal Town need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Is colour matching possible?

In many cases, 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.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Do you do washroom sealing in healthcare settings?

Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

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. In Kensal Town, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
