Toilets, showers and kitchens around Woking

The area within 2 miles of Woking holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available. At about 24 miles from central London, Woking is within reach of the capital, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

On an industrial estate such as Goldsworth Park Trading Estate, which lies north-west of Woking, staff toilets, showers and canteens are where sanitary sealant takes the most wear. At a hotel such as DoubleTree by Hilton Hotel Woking, 0.9 miles to the north-east of Woking, the quieter weeks are the time to reseal bathrooms. At a college such as Woking College, 1.3 miles south-east of Woking, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Woking is about 24 miles south-west of London, in Surrey. We send applicators to Woking for washrooms and wet areas. Across Surrey, 379 places are covered, Woking among them. We also cover Reading, some 20 miles away.

If you need washroom sealing in GU21, GU22, GU24 and GU3, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. For a building on High Street, Market Walk and Gloucester Square or nearby, we can quote for washrooms and wet areas. Main routes into Woking include the A247 and A320, which helps when planning parking and deliveries for the job. We also cover Goldsworth Park (1 mile west), St John's (1 mile west), Horsell (1 mile north-east), Westfield (1 mile south-east) and Mimbridge (2 miles north) for washrooms and wet areas. Nearby towns on our patch include Guildford (5 miles south), Camberley (7 miles west), Epsom (13 miles east), Farnham (12 miles south-west), Ewell (14 miles east) and Egham (8 miles north). As one of the bigger centres in Surrey, Woking has a broad mix of commercial, public and industrial buildings, and we cover them all.

Washroom sealing for commercial buildings in Woking

Whether it’s a single toilet block in Woking or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. If you have shower tray joints that have opened up and gaps where vanity tops meet the wall, we can put it right, on kitchens and tea points, IPS panels and cubicles and vanity units and basins alike. A specialist sealant contractor works differently from a general builder: in Woking, that means joint design, primers and backing rod as standard.

Retail parks, shopping centres and business parks around large towns like Woking have customer and staff toilets that rarely close. Phased work keeps enough facilities open while the sealant is replaced.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • A dripping waste or valve behind a panel
  • Panel boards already damaged by water

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

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

After the work

To get the most from the new sealant:

  • Keep washrooms out of use until we say the sealant has cured
  • Share your site rules when you send details
  • Avoid scourers and harsh descalers on silicone
  • Report faulty extraction promptly

Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

Why deal with it now?

Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. If one joint has failed on your building in Woking, others of the same age may be close behind. Renewing them in one programme saves time later.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • Fully insured
  • Commercial sealant work since 2005
  • Fixed quotes based on photographs, drawings or a visit
  • Failed material removed, not covered up

Woking: questions and answers

Must a hotel around Woking close while you work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

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

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.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.

What guarantee comes with washroom resealing?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

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 clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint normally 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

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. In a large town like Woking, work on busy buildings is planned area by area, keeping disruption low. Send drawings or photographs and we’ll set out a phasing plan with the quote.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space
  • Warn occupants and staff about the work

Quotes

Surface by surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Basins and vanity tops

Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
