Washroom sealing near Kent Street

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

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Phasing around occupants
  • The size and state of each joint
  • Access and working height
  • Induction, permit and paperwork requirements

The specified product makes a difference, 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

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

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • The postcode of the building
  • What the building is and how it’s used

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, speak to us on 01277 525 020 or send photos by email.

Washroom sealing in Kent Street

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. Site teams most often ask us about open joints along basins and vanity units and failed joints along IPS and cubicle panels, on urinals and WCs, showers, trays and wet room floors and accessible toilets and changing rooms. Most enquiries from Kent Street start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller places such as Kent Street still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Aftercare for building managers

After handover, these steps help:

  • Don’t leave an open joint at a basin or tray
  • Share your site rules when you send details
  • Don’t leave trays and floors sitting wet
  • Keep washrooms out of use until we say the sealant has cured

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

Keeping Kent Street washrooms open while we work

At about 26 miles from central London, Kent Street is within reach of the capital, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Halls linked to places like St Lawrence's Church host groups all week, which is hard on kitchen and toilet sealant. Halls of residence and teaching buildings at universities such as University for the Creative Arts - Maidstone (to the east of Kent Street) are easiest to reseal during vacations.

Kent Street is about 6 miles west of Maidstone, in Kent. Across the ME18 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Kent Street is one of 931 places we cover in Kent. There’s a separate page for London, about 26 miles away.

Postcode districts covered here: ME18 for washrooms and wet areas. Among the streets we cover are Kent Street and Malling Road, and sites on any of them can send details for a fixed quote.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Kent Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Before we start on site

Advice

Your questions answered

Is a smaller place like Kent Street outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work around term dates at a campus such as University for the Creative Arts - Maidstone?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

How do you deal with asbestos in old sealant?

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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long does a typical visit take?

It depends on the scope, but the work normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Different surfaces, different methods

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.

Healthcare and care settings

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

Leave it or put it right?

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. For buildings around smaller places like Kent Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

When to call us in Kent Street

Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.

It’s worth sending us details if you spot any of the following:

  • Sealant stained black around basins and showers
  • Shower tray joints that have opened up
  • Users noticing mouldy joints
  • Sealant laid over old silicone and now peeling

If you manage an office at a site such as Kings Hill Business Park, 0.8 miles north-east of Kent Street, the washrooms and tea points can be done a floor at a time.
