Washroom sealing for Lions Green sites

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

Washroom sealing for commercial buildings in Lions Green

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on accessible toilets and changing rooms, urinals and WCs and vanity units and basins, and the failures we’re asked to look at most are sealant laid over old silicone and now peeling and users noticing mouldy joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lions Green is the same: the right product in a properly prepared joint.

Rural businesses near smaller places such as Lions Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Why deal with it now?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. Around Lions Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why clients in Lions Green choose us

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Looking after the joints

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

  • Report split joints at trays and basins early
  • Avoid scourers and harsh descalers on silicone
  • Keep extract fans working and vents clear
  • Include joints in routine washroom inspections

We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used and signage stays in place until that time.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

Sanitary sealant for Lions Green buildings

At about 41 miles from central London, Lions Green is within reach of the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

For buildings on a site such as Merrydown Business Park, which lies south-east of Lions Green, washrooms and tea points can be resealed in phases through the working week. Healthcare estates like Hellingly Hospital Railway, 4.1 miles to the south-east of Lions Green, expect contractors to follow their permits and cleaning rules in every washroom. Where you are responsible for a hall attached to a building such as The Parish Church of All Saints, its kitchen and toilets need sealant that stays cleanable.

Lions Green is about 5 miles east of Uckfield, in East Sussex. Businesses, contractors and managing agents in Lions Green can call on us for washrooms and wet areas, as part of our coverage of East Sussex.

Questions we’re asked in Lions Green

Is a smaller place like Lions Green outside your area?

Not at all. Lions Green is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Hellingly Hospital Railway?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you phase washroom resealing?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.

How long do sealant joints 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.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How the job changes by surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a building around Lions Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

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

What we need from you

  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
