Lockerley: questions and answers

Must every washroom in our Lockerley building shut while you work?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Can you work on a hospital site such as Romsey Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you cover Lockerley?

Yes. Lockerley is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or use the quote form.

How many days will you need on site?

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

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Do you phase washroom resealing?

Only the area we’re working in is closed. Each room reopens after the sealant’s cure time and we start the next.

How we handle washroom sealing in Lockerley

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we will confirm with the quote. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and what we are called in for most is stained sealant around pans and urinals and failed sealant in a tea point or staff kitchen. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lockerley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Community buildings around smaller places like Lockerley have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Distance, for remote addresses
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • The size and state of each joint

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

However big the job, these details speed things up:

  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Any dates the work must fit around

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

How a job runs

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 the sealant is tooled off neatly. If others near Lockerley 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. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Getting the site ready

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints

Related advice

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes
  • Loose panels, vanity units or tiles, which need fixing first

If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Surfaces we seal

  • IPS panels and cubicles
  • Vanity units and basins
  • Kitchens and tea points
  • Urinals and WCs
  • Showers, trays and wet room floors
  • Accessible toilets and changing rooms

When to call us in Lockerley

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting and they discolour and fail early.

Any of the following is a good reason to get the joints checked over:

  • Black mould inside silicone joints that cleaning can’t shift
  • Sealant laid over old silicone and now peeling
  • Split or peeling sealant at shower trays
  • Stained or open joints at kitchen sinks and worktops

Halls linked to places like Church of St John host groups all week, which is hard on kitchen and toilet sealant.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents

Our contractor checklist

After the work

After handover, a little attention goes a long way:

  • Report faulty extraction promptly
  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.
