Washroom sealing for Freemantle sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

Washroom sealing for commercial buildings in Freemantle

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with complaints from staff, guests or users about tired washrooms and sealant stained black around basins and showers, we can put it right, on accessible toilets and changing rooms, IPS panels and cubicles and vanity units and basins alike. Looking for mastic applicators who cover Freemantle? We have been sealing commercial buildings since 2005.

In and around places like Freemantle, hospitality kitchens and toilets see heavy use in busy spells. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Share your site rules when you send details
  • Don’t leave trays and floors sitting wet
  • Brief cleaning staff to treat joints gently
  • Respect the cure time before reopening each room

Each room goes back into use only when the sealant has cured enough. We will tell you when the wet areas can be used, and it helps if signs stay up until then.

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

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Work in places the size of Freemantle is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We agree which washrooms close and when.
  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.

Getting the site ready

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Wet areas in Freemantle’s workplaces

Freemantle lies within about 1 mile of the sea, 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. There are a good number of hotels within about 2 miles of Freemantle. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.

At a university such as Southampton Solent University (1.1 miles east of Freemantle), summer is the usual window for resealing residence bathrooms. On an industrial estate such as Liners Industrial Estate, under half a mile to the north of Freemantle, staff toilets, showers and canteens are where sanitary sealant takes the most wear. For a college such as Richard Taunton Sixth Form College, which lies north of Freemantle, half-term and summer give the windows for washroom work.

Freemantle is about 1 mile west of Southampton, in Southampton. Businesses, contractors and managing agents in Freemantle use us for work on washrooms and wet areas, as part of our coverage of Southampton. Freemantle is one of 30 places in Southampton on our list.

FAQs: Freemantle

Do hotels near Freemantle have to close for sealant work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Will you plan work around the academic year at somewhere like Southampton Solent University?

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.

Is colour matching possible?

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

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

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. The first step only needs photographs and a postcode.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

What happens if it’s left?

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

A quote for washrooms and wet areas depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
