How we handle washroom sealing in Fulham

From one staff toilet in Fulham to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photographs and a count of fittings are enough for a quick quote, or we can arrange a visit. If you are dealing with a new bead over an old one coming away and stained or open joints at kitchen sinks and worktops, we can help, whatever the surface. Most enquiries from Fulham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Building managers in Fulham normally need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

FAQs: Fulham

Could you schedule work at a campus like BIMM University 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.

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

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is Fulham in your area?

Yes. We cover Fulham and the rest of Greater London. To discuss a job, ring 01277 525 020 or email the details over.

Busy facilities in and around Fulham

There are a good number of hotels within about 2 miles of Fulham. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available. A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance.

Customer toilets in retail centres such as Kensington Arcade, 1.7 miles north of Fulham, rarely close, so resealing is phased. For a campus such as BIMM University, which lies east of Fulham, showers in residences and washrooms in teaching blocks can be programmed around term dates. Clinical washrooms at sites like Charing Cross Hospital, 0.8 miles to the north-west of Fulham, are scheduled with the ward so the room is out of use for as little time as possible.

Fulham is about 2 miles south of Kensington, in Greater London. Any commercial site in Fulham is covered, for single jobs and planned programmes alike. Our Greater London coverage takes in 764 places, from busy centres to rural villages.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Mention any site permits or estates rules at quote stage
  • Don’t leave trays and floors sitting wet
  • Make sure washroom ventilation is running
  • Add sealant joints to planned maintenance checks

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface over time.

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

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Quantities, in metres or numbers
  • Phasing around occupants
  • Backing rod, priming and other preparation
  • The site’s rules and procedures

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

We can often quote from photographs and a few details. Please tell us:

  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • The type of building and who uses it

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.

Why act early in Fulham

Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Failed sealant in a building in Fulham can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

On site: what to expect

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 anything is cut or cleaned, and the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. In Fulham, 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. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Different surfaces, different methods

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.
