Questions about St George's Hill

Can you work around term dates at a campus such as Brooklands Technical College - Weybridge Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you take on a job at a hospital such as Walton Community Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Washroom sealing in St George's Hill, done properly

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 mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have resealing that didn’t last because the old bead stayed and discoloured joints around urinals and WC pans, we can help, whatever the surface. A single leaking joint is often how a building in St George's Hill first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around places like St George's Hill, hospitality kitchens and toilets see heavy use in busy spells. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Sanitary sealant for St George's Hill buildings

The area within 2 miles of St George's Hill holds plenty of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping. St George's Hill has three care or nursing homes no more than 2 miles away. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible.

En suites at hotels like The Hand and Spear Hotel (0.6 miles west of St George's Hill) are cleaned daily, which wears silicone over time. Office toilets at parks like Wintersells Business Park (1.6 miles south-west of St George's Hill) take steady weekday use, and mouldy silicone soon shows.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Report faulty extraction promptly
  • Photograph and log failed joints across the estate
  • Leave signs up until the cure time is over
  • Mention any site permits or estates rules at quote stage

If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, regular checks keep small problems small.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • A dripping waste or valve behind a panel
  • Fittings that move too much to hold a bead
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

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

Signs you need washroom sealing in St George's Hill

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.

What tends to prompt an enquiry:

  • Stained sealant around pans and urinals
  • Complaints from staff, guests or users about tired washrooms
  • Panel joints letting water behind
  • Split or peeling sealant at shower trays

Clinical washrooms at sites like Walton Community Hospital (to the north-east of St George's Hill) are scheduled with the ward so the room is out of use for as little time as possible.

Questions to ask before you book

  • What site paperwork they can supply
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • What the guarantee covers, and for how long

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’ll confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Site staff or a sealant specialist?

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.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around St George's Hill need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Before we start on site

  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.
