Washroom sealing for businesses in Hunston

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

Your questions answered

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

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Must a hotel around Hunston close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Do you offer coloured sealant?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Washroom sealing in Hunston, done properly

From one staff toilet in Hunston to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. We work on accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points, and the failures we’re asked to look at most are stained or open joints at kitchen sinks and worktops and stained sealant around pans and urinals. Whoever orders the work in Hunston, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Hunston, 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Act on the first split you see at a shower tray
  • Inspect washroom sealant regularly
  • Make sure washroom ventilation is running
  • Keep a record of which washrooms need attention

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Busy facilities in and around Hunston

Hunston sits close to the coast, within about 3 miles, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Showers and en suites in constant use are where silicone moulds and splits first, so we plan the work for quieter weeks where possible. A number of hotels sit less than 2 miles from Hunston. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.

Hotels such as Crouchers Hotel (to the west of Hunston) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Office toilets at parks like City Business Park (to the north of Hunston) take steady weekday use, and mouldy silicone soon shows. On a healthcare site such as St Richard's Hospital (2.3 miles north of Hunston), washroom work starts with the infection-control team’s sign-off.

Hunston is about 2 miles south of Chichester, in West Sussex. We cover Hunston and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 373 places in West Sussex, from busy centres to rural villages. We also cover Portsmouth, some 13 miles away.

Business premises anywhere in PO20 are within our area. If your site is on Heath Close, Westlands Road and St Leodegars Way or close by, we can quote for washrooms and wet areas. If your building is just outside Hunston, we cover Donnington (1 mile west), North Mundham (1 mile east), Runcton (1 mile east), Portfield (2 miles north) and Chichester (2 miles north). Nearby towns on our patch include Bognor Regis (4 miles east), Selsey (5 miles south), Littlehampton (11 miles east), Rustington (12 miles east), Angmering (13 miles east) and Yapton (7 miles east).

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Different surfaces, different methods

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

What sets the cost

What shapes the price:

  • Travel to remote or island sites
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Access details, including height
  • The site address and postcode

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, phone 01277 525 020 or email the details over.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Condensation from failed extract fans
  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
