Washroom sealing near Cheapside

Washroom sealing in Cheapside, done properly

You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you have split or peeling sealant at shower trays and complaints from staff, guests or users about tired washrooms, we can help, on showers, trays and wet room floors, IPS panels and cubicles and vanity units and basins alike. One point of contact handles commercial sealant work in Cheapside from the first photos to the final walk-round, whether it’s one building or several.

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

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Common problems we fix in Cheapside

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

If one of these sounds familiar, it’s time for a closer look:

  • Sealant laid over old silicone and now peeling
  • Users noticing mouldy joints
  • Black mould inside silicone joints that cleaning can’t shift
  • Kitchen worktop joints that can’t be kept clean

Student showers at universities like Imperial College Silwood Park Campus, 0.5 miles to the south of Cheapside, see more use than most, and their silicone shows it.

Before you book anyone

  • Their public liability cover
  • Their pre-qualification and accreditations
  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Different surfaces, different methods

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we’ll say so before resealing.

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we’ll plan around them.

What affects the price in Cheapside

To price the job, we consider:

  • How much there is to seal
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

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

  • The postcode of the building
  • Your programme or deadline
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. One visit to deal with every failing joint makes more sense than several trips to a place like Cheapside, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Why appoint us

  • Over 20 years of commercial sealing
  • Fully insured, including public liability cover
  • Work carried out by CSCS-carded applicators
  • CHAS accredited

Questions about Cheapside

Do you work in occupied care homes around Cheapside?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Must a hotel around Cheapside close while you work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
