Washroom sealing across Broadstairs

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • A room that stays damp because ventilation isn’t working
  • Loose panels, vanity units or tiles, which need fixing first
  • A dripping waste or valve behind a panel

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

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

How we handle washroom sealing in Broadstairs

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. Only replacement gets rid of it for good. If you are dealing with washrooms that look worn because of the sealant and sealant lifting along a tray edge, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Broadstairs, that means joint design, primers and backing rod as standard.

For hospitality businesses in towns like Broadstairs, sealed joints in kitchens and toilets help keep surfaces easy to clean. Environmental health officers look at cleanability, and a sound sanitary or hygienic sealant is part of that.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Leave it or put it right?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. For businesses and landlords in Broadstairs, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why appoint us

  • CSCS-carded applicators
  • Old sealant cut out, never sealed over
  • One phone line for London, the South East and Scotland
  • 12 months’ guarantee on every job

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Washroom sealing in Broadstairs: the local picture

Broadstairs lies within about 1 mile of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. A good number of hotels sit less than 2 miles from Broadstairs. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.

Toilets at places like Broadstairs Retail Park, 1.3 miles to the west of Broadstairs, are cleaned constantly, so silicone needs to be sound and smooth. Clinical washrooms at sites like Queen Elizabeth The Queen Mother Hospital (to the north-west of Broadstairs) are scheduled with the ward so the room is out of use for as little time as possible.

Broadstairs is about 16 miles east of Canterbury, in Kent. We cover Broadstairs, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Broadstairs is one of 931 places we cover in Kent. Sites around London have their own page, roughly 66 miles from Broadstairs.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Parking and loading for town-centre jobs in Broadstairs are worth mentioning when you send details. Industrial and business units typically have yard or car park space.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Let us know about inductions and permits
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

Your questions answered

Does a hotel in Broadstairs 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. Tell us your quiet periods and access windows and we’ll plan around them.

Will you plan work around the academic year at somewhere like EKC Broadstairs College?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you quote from photographs?

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

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

How long does a job like this take?

It depends on the scope, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.

When to call us in Broadstairs

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

These are often picked up first by site or facilities staff:

  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels
  • Stained or open joints at kitchen sinks and worktops
  • Sealant stained black around basins and showers

Toilets at colleges like EKC Broadstairs College (0.6 miles south-east of Broadstairs) take heavy use from students and staff alike.

Questions to ask before you book

  • What site paperwork they can supply
  • How joint depth will be controlled
  • How long is the guarantee, and what does it include?
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Surface by surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.
