Washroom sealing for commercial buildings in Rochester Riverside

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, vanity units and basins and accessible toilets and changing rooms, and what we are called in for most is discoloured joints around urinals and WC pans and a new bead over an old one coming away. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Rochester Riverside is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around places like Rochester Riverside, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Cost factors for washrooms and wet areas

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

  • Backing rod, priming and other preparation
  • The product specified
  • Any access equipment needed
  • Phasing around occupants

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

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

  • The site address and postcode
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. What matters most for a job in Rochester Riverside is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  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.

Before we start on site

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Share your working hours and any access restrictions

Advice

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Maintenance after handover

Once the work is signed off, these steps help:

  • Make sure washroom ventilation is running
  • Inspect washroom sealant regularly
  • Leave signs up until the cure time is over
  • Avoid scourers and harsh descalers on silicone

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

When to bring in a specialist

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

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Wet areas in Rochester Riverside’s workplaces

Rochester Riverside sits close to the coast, within about 3 miles, and seaside hospitality normally has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. Rochester Riverside has two care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

At a college such as MidKent College Gillingham Campus, 1.5 miles to the east of Rochester Riverside, washroom and kitchen sealant is best renewed in the holidays or in phases during term. At a hotel such as The Gordon Hotel, under half a mile south-west of Rochester Riverside, the quieter weeks are the time to reseal bathrooms. If you manage an office at a site such as Castle View Business Centre, which lies north of Rochester Riverside, the washrooms and tea points can be done a floor at a time.

Rochester Riverside is about 1 mile east of Rochester, in Medway. Anywhere in ME1, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 54 places in Medway, large and small. Our London page has more on work in that area.

Anyone looking for washroom sealing in ME1, ME2 and ME3 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Questions we’re asked in Rochester Riverside

Is a smaller place like Rochester Riverside outside your area?

Not at all. Rochester Riverside is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Do you work in occupied care homes around Rochester Riverside?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Different surfaces, different methods

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.
