Washroom sealing for commercial buildings in Oliver's Battery

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. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on urinals and WCs, kitchens and tea points and showers, trays and wet room floors, and the usual reasons a site gets in touch are black mould inside silicone joints that cleaning can’t shift and resealing that didn’t last because the old bead stayed. Whoever orders the work in Oliver's Battery, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Farm shops, cafés and venues in converted rural buildings around places like Oliver's Battery have busy toilets and kitchens. We plan the work around bookings and opening times.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. Older rural buildings around Oliver's Battery move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why clients in Oliver's Battery choose us

  • Fully insured
  • Colours chosen to suit frames, cladding or finishes where possible

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.

Redoing a failed joint normally 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.

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. If others near Oliver's Battery need work, visits can be combined. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work

Advice

Do you need washroom sealing in Oliver's Battery?

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.

What tends to prompt an enquiry:

  • Open joints along basins and vanity units
  • Mould spotting along silicone joints
  • Urinal joints that look unhygienic
  • Complaints from staff, guests or users about tired washrooms

On an industrial estate such as Bar End Industrial Estate (2 miles east of Oliver's Battery), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Their plan for phasing and protecting the area

Our contractor checklist

Oliver's Battery: questions and answers

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

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Oliver's Battery too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What do you charge?

We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.

Can washrooms stay open while you work?

The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Swollen or delaminated boards behind panels or vanity tops
  • Water from plumbing, not from a joint
  • Fittings that move too much to hold a bead

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

Joints and surfaces we work on

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

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Toilets, showers and kitchens around Oliver's Battery

There are two care or nursing homes within about 2 miles of Oliver's Battery. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Work is agreed with the manager, around residents’ routines. Oliver's Battery has several hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.
