Washroom sealing in Lewson Street

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

About our washroom sealing in Lewson Street

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. If you are dealing with sealant stained black around basins and showers and urinal joints that look unhygienic, we can help, on vanity units and basins, urinals and WCs and showers, trays and wet room floors alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lewson Street it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Lewson Street, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Washroom sealing around Lewson Street: what changes locally

Lewson Street is within about 3 miles of the coast, and seaside hospitality usually has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, so we plan the work for quieter weeks where possible. Lewson Street is about 41 miles from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

Where you are responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable.

Lewson Street is about 3 miles west of Faversham, in Kent. We cover commercial sites throughout Lewson Street, for single jobs and planned programmes alike. Lewson Street is one of 931 places we cover in Kent for washrooms and wet areas. Our London page has more on work in that area, about 41 miles away.

Advice

Surface by surface

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements as well as site permits.

Common problems we fix in Lewson Street

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

It’s worth sending us details if you spot any of the following:

  • Failed joints along IPS and cubicle panels
  • Open joints along basins and vanity units
  • Urinal joints that look unhygienic
  • Stained or open joints at kitchen sinks and worktops

At a school such as Teynham Parochial Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Choosing a commercial sealant contractor

What happens if it’s left?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. For buildings around smaller places like Lewson Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Why clients in Lewson Street choose us

  • Old sealant cut out, never sealed over
  • CSCS-carded applicators
  • Colour options checked against the specified product
  • One phone line for London, the South East and Scotland

Take a look at our cost guide or how we’re accredited.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans

If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Joints and surfaces we work on

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

FAQs: Lewson Street

What site paperwork comes with a job in Lewson Street?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is a smaller place like Lewson Street outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can the sealant be colour-matched?

In many cases, 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 use special sealant for toilets and showers?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Do you take on multi-site work?

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.
