Washroom sealing for commercial buildings in Navestock Common

In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you are dealing with failed joints along IPS and cubicle panels and users noticing mouldy joints, we can put it right, on kitchens and tea points, urinals and WCs and IPS panels and cubicles alike. One point of contact handles commercial sealant work in Navestock Common from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Smaller places such as Navestock Common still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Navestock Common need work, visits can be combined. A fixed quote is given before anything starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  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.

Getting the site ready

  • Let building users know which areas are affected
  • Agree which areas must stay open

What the job involves on each surface

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we’ll confirm with the quote.

IPS and cubicle panels

Swollen or delaminated boards need replacing and we will point out any we see.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Navestock Common lies roughly 16 miles out from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Toilets at colleges like Havering Technical College (to the south-east of Navestock Common) take heavy use from students and staff alike. Staff changing rooms and patient toilets at places like Suttons Manor Hospital, 2.2 miles to the north-west of Navestock Common, need cleanable, sound silicone. Where you are responsible for a hall attached to a building such as Church of St Thomas, its kitchen and toilets need sealant that stays cleanable.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Whether the work must be split into stages
  • The product specified
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • Whether an asbestos survey exists

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or email the details over.

Why it’s worth doing now in Navestock Common

Bleaching black sealant may lighten it for a few days, 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. One visit to deal with every failing joint makes more sense than several trips to a place like Navestock Common, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why clients in Navestock Common choose us

  • RAL and finish matching where the product range allows
  • A Constructionline member, so easy to vet
  • Colour options checked against the specified product
  • A fixed quote before work starts

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Your questions answered

Is Navestock Common off your patch?

No. Places such as Navestock Common are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can work at a site such as Havering Technical College fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
