Washroom sealing for Lexden sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Commercial clients in Lexden

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Lexden. One quote can cover more than one site, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Washroom sealing for commercial buildings in Lexden

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with complaints from staff, guests or users about tired washrooms and urinal joints that look unhygienic, we can put it right, on accessible toilets and changing rooms, vanity units and basins and urinals and WCs alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Lexden it comes down to the same thing: the right product in a properly prepared joint.

A place of Lexden’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Lexden is a clear list of what needs doing. A fixed quote follows.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

FAQs: Lexden

Can you work around term dates at a campus such as University of Essex?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Does a hotel in Lexden need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What will the job cost?

Each job is quoted on its own details. To get one, ring 01277 525 020 or email us with a description of the work.

When can showers be used after new sealant?

Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.

Do you need to see the site first?

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

How many days will you need on site?

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

What sealant work can’t fix

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

  • Fittings that move too much to hold a bead
  • A dripping waste or valve behind a panel
  • Water escaping beneath the floor rather than through a joint

If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.

What we seal

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

Looking after the joints

A few simple habits keep the new joints working:

  • Keep a record of which washrooms need attention
  • Respect the cure time before reopening each room
  • Squeegee showers and trays after busy periods
  • Mention any site permits or estates rules at quote stage

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Washroom sealing around Lexden: points for this area

At about 49 miles from central London, Lexden is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time. The area within 2 miles of Lexden holds a good number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Clinical washrooms at sites like Oaks Hospital (to the north-east of Lexden) are scheduled with the ward so the room is out of use for as little time as possible. Student showers at universities like University of Essex (3.4 miles east of Lexden) see more use than most, and their silicone shows it.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.

Do you need washroom sealing in Lexden?

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Most enquiries start with one or more of the following:

  • Sealant laid over old silicone and now peeling
  • Users noticing mouldy joints
  • Panel joints letting water behind
  • Kitchen worktop joints that can’t be kept clean

For a hotel such as The Grosvenor Hotel, which lies east of Lexden, resealing en suites a few rooms at a time keeps the rest available.
