Washroom sealing across Little London

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

Different surfaces, different methods

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Washroom sealing in Little London

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. We work on vanity units and basins, accessible toilets and changing rooms and urinals and WCs, and the usual reasons a site gets in touch are gaps where vanity tops meet the wall and urinal joints that look unhygienic. Whoever orders the work in Little London, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Halls and community buildings near places like Little London are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Commercial clients in Little London

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Little London can sit alongside others in a wider programme.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • A room that stays damp because ventilation isn’t working
  • Hollow tiles or loose panels behind the joint
  • Water from plumbing, not from a joint

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

What affects the price in Little London

These are the things that shape the price:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Your programme or deadline
  • Any specification or named product
  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email us.

Keeping Little London washrooms open while we work

Little London lies roughly 26 miles out from central London. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

At a school such as Shere CofE Aided Infant School, changing rooms and kitchens need cleanable joints as much as the toilets. Staff changing rooms and patient toilets at places like St. Luke’s Hospital (to the north-west of Little London) need cleanable, sound silicone.

Little London is about 5 miles south-east of Guildford, in Surrey. Commercial clients in Little London can call on us for washrooms and wet areas, as part of our coverage of Surrey. Little London is one of 379 places we cover in Surrey. London is covered too, around 26 miles from Little London.

What we’re called out for in Little London

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old so it peels away quickly.

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

  • Complaints from staff, guests or users about tired washrooms
  • Stained or open joints at kitchen sinks and worktops
  • Failed sealant behind washroom basins
  • Sealant stained black around basins and showers

Halls linked to places like Old St Peter and St Paul's Church host groups all week, which is hard on kitchen and toilet sealant.

What your quote should include

  • How they handle RAMS and site documents
  • Their approach to joint depth and backing
  • How the existing material will be dealt with
  • What level of public liability insurance do they hold?

Our contractor checklist

Your questions answered

Do we have to close all our washrooms in Little London for resealing?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Would you work within a site like St. Luke’s Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What sealant do you use in washrooms?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Little London, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  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. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Confirm the product named in the specification
