Washroom sealing for commercial buildings in Oakthorpe Park

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you have washrooms that look worn because of the sealant and a new bead over an old one coming away, we can help, on IPS panels and cubicles, urinals and WCs and vanity units and basins alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Oakthorpe Park, that means joint design, primers and backing rod as standard.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.

Every job we finish is backed by a 12-month workmanship guarantee, in Oakthorpe Park as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What sets the cost

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • Any access equipment needed
  • Distance, for remote addresses

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • What the building is and how it’s used
  • A wide shot and a close-up of the area

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

How the job changes by surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.

Changing rooms and gyms

Shower areas, wet floor edges and vanity areas all have sealant joints and we look at them as one job.

Leave it or put it right?

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a job in Oakthorpe Park, access comes first. Send the building rules and access times with your enquiry.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Confirm the product named in the specification

Advice

Keeping Oakthorpe Park washrooms open while we work

There are three care or nursing homes within about 2 miles of Oakthorpe Park. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Rooms are done a few at a time at times agreed with the home. A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time.

Units at estates like St. George's Industrial Estate (0.7 miles south-east of Oakthorpe Park) have welfare blocks whose showers and toilets see shift after shift. At a hospital like Priory Hospital, 1.3 miles north-west of Oakthorpe Park, patient and staff washrooms are best done in short phases agreed with the ward. Toilets at places like The Mall Wood Green, 1.4 miles south of Oakthorpe Park, are cleaned constantly, so silicone needs to be sound and smooth.

FAQs: Oakthorpe Park

Can you cope with the access rules in a London building?

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 will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Do you work in occupied care homes around Oakthorpe Park?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you clean the mould off instead of resealing?

Typically not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Oakthorpe Park can form part of a wider programme across Greater London.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Vanity carcasses that have swollen

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

  • Urinals and WCs
  • Vanity units and basins
