Sanitary sealant for Strand-on-the-Green buildings

A London building with hundreds of occupants can’t lose every washroom for a day, so resealing goes floor by floor, agreed with the facilities team. A 2-mile radius around Strand-on-the-Green takes in plenty of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping.

Halls of residence and teaching buildings at universities such as Richmond American University London (0.6 miles north of Strand-on-the-Green) are easiest to reseal during vacations. For a store at a site such as Kew Retail Park, 0.5 miles south of Strand-on-the-Green, the staff room and customer toilets can be resealed in quiet periods.

Different surfaces, different methods

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements and any permits the site uses.

Common problems we fix in Strand-on-the-Green

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.

Look out for the following:

  • A new bead over an old one coming away
  • Split or peeling sealant at shower trays
  • Black mould inside silicone joints that cleaning can’t shift
  • Users noticing mouldy joints

At a hotel such as Clayton Hotel Chiswick, 0.6 miles north of Strand-on-the-Green, the quieter weeks are the time to reseal bathrooms.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

How the quote is worked out

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

  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • How much existing material needs removing

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.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height
  • The asbestos register, for older buildings

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Include joints in routine washroom inspections
  • Keep washrooms out of use until we say the sealant has cured
  • Squeegee showers and trays after busy periods
  • Mention any site permits or estates rules at quote stage

We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used, and it helps if signs stay up until then.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

Commercial clients in Strand-on-the-Green

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Strand-on-the-Green can form part of a wider programme across Greater London.

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.

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 your contact hears from us before we move to the next area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  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. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Warn occupants and staff about the work
  • Flag any permit to work we will need
  • Have the specification and drawings to hand

Ask for a quote

To get a fixed quote, give us a call on 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

Advice

Strand-on-the-Green: questions and answers

Could you schedule work at a campus like Richmond American University London for the vacation?

Yes. Education sites usually 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.

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Is Strand-on-the-Green in your area?

Yes. Sites across Strand-on-the-Green are covered.

Is colour matching possible?

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

Do you hold CHAS accreditation?

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

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
