Washroom sealing for commercial buildings in Goose Green

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. Most enquiries involve open joints along basins and vanity units and stained or open joints at kitchen sinks and worktops, on vanity units and basins, kitchens and tea points and urinals and WCs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Goose Green, preparation and product choice get the time they need.

Halls and community buildings near places like Goose Green 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • A dripping waste or valve behind a panel
  • Hollow tiles or loose panels behind the joint
  • Leaks through tanking or membranes below the finishes

If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think before you book.

What we seal

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

Goose Green: questions and answers

What documents will you need to give us for a job in Goose Green?

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.

Will all the washrooms in our Goose Green building be closed at once?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Goose Green are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space
  • Agree which areas must stay open

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Advice

Signs you need washroom sealing in Goose Green

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.

Common reasons buildings call us in:

  • Complaints from staff, guests or users about tired washrooms
  • Failed sealant behind washroom basins
  • Stained sealant around pans and urinals
  • Sealant stained black around basins and showers

Office washrooms on sites such as Crays Court (business park) (to the south-west of Goose Green) are in use all working day, so resealing is phased to keep some open.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS

Choosing a commercial sealant contractor

Keeping Goose Green washrooms open while we work

Central London is about 40 miles from Goose Green. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

Halls linked to places like The Parish Church of St Mary host groups all week, which is hard on kitchen and toilet sealant. Pupil toilets at schools like Rydon Community College take heavy daily use, and the holidays give the window to reseal.

Goose Green is about 9 miles south-west of Horsham, in West Sussex. Anywhere in RH20, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our West Sussex coverage takes in 373 places. Our Brighton page has more on work in that area.

Commercial sites across RH20 are covered. We cover commercial and managed buildings on Goosegreen Lane and Cray's Lane. We also cover Thakeham (1 mile south-west), Warminghurst (1 mile south), Abingworth (1 mile south-west), West Chiltington (2 miles west) and Heath Common (2 miles south) for washrooms and wet areas. A short drive away, we cover Crawley (14 miles north-east), Horsham (9 miles north-east), Worthing (9 miles south), Haywards Heath (14 miles east), Burgess Hill (12 miles east) and Littlehampton (11 miles south-west).

Different surfaces, different methods

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.

After the work

To get the most from the new sealant:

  • Tell us about infection-control or permit rules before we quote
  • Brief cleaning staff to treat joints gently
  • Keep washrooms out of use until we say the sealant has cured
  • Keep extract fans working and vents clear

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
