Washroom sealing in Grange Park

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

Washroom sealing in Grange Park

You can’t shut every toilet in an office, school or hotel at once. 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. The enquiries we see most involve users noticing mouldy joints and sealant laid over old silicone and now peeling, on accessible toilets and changing rooms, urinals and WCs and vanity units and basins. Most enquiries from Grange Park 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.

In Grange Park, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Sanitary sealant for Grange Park buildings

London offices and hotels typically can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager. A 2-mile radius around Grange Park takes in a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

Halls linked to places like Church of St Mary Magdalene host groups all week, which is hard on kitchen and toilet sealant. At a college such as Oak Hill College, which lies west of Grange Park, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Clinical washrooms at sites like The Cavell Hospital (to the north of Grange Park) are scheduled with the ward so the room is out of use for as little time as possible.

Grange Park is about 3 miles north-west of Edmonton, in Greater London. If you are looking for washroom sealing in Grange Park, we can help, as we do across Greater London. Across Greater London, 764 places are covered, including Grange Park. For work in that direction, see our London page, about 10 miles away.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • The total length or number of joints
  • The size and state of each joint
  • Working within restricted access windows
  • How accessible the joints are

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode

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

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For a job in Grange Park, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  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.

Preparing the site

  • Let us know about inductions and permits
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

Advice

Different surfaces, different methods

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Records you need can be confirmed with the quote.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Keep extract fans working and vents clear
  • Don’t leave trays and floors sitting wet
  • Keep a record of which washrooms need attention
  • Mention any site permits or estates rules at quote stage

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.

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.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Water escaping beneath the floor rather than through a joint
  • Fittings that move too much to hold a bead

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

Your questions answered

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

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Must a hotel around Grange Park close while you 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 handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What guarantee comes with washroom resealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
