Washroom sealing for Chichester sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Hollow tiles or loose panels behind the joint
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Where we work in Chichester

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

How we handle washroom sealing in Chichester

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you have open joints along basins and vanity units and stained or open joints at kitchen sinks and worktops, we can help, whatever the surface. For commercial sealant work in Chichester, you deal with one contact from quote to sign-off, whether it’s one building or several.

Pubs, restaurants and cafés in a town like Chichester have kitchens and customer toilets that need smooth, sealed joints. Environmental health officers look at cleanability, and a sound sanitary or hygienic sealant is part of that.

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

FAQs: Chichester

Do you work in occupied care homes around Chichester?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Do hotels near Chichester have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

What sealant do you use in washrooms?

An anti-mould sanitary silicone in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If you have more than one building in Chichester, they can often be done on the same visit. Give us your access times and we will fit the work in.

  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. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

What we need from you

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work

Related advice

Why deal with it now?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. In a town like Chichester, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

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 rules also count.

Why us?

  • Specification-led, product-correct work
  • Commercial sealant work since 2005
  • Public liability insurance in place
  • Work carried out by CSCS-carded applicators

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Chichester can form part of a wider programme.

Washroom sealing around Chichester: points for this area

Chichester is about 54 miles from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open. The 2 miles around Chichester include three care or nursing homes. 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.

In a centre such as Summersdale Retail Park, which lies north of Chichester, public washrooms are resealed a block of facilities at a time. For a campus such as University of Chichester (less than half a mile north-east of Chichester), showers in residences and washrooms in teaching blocks can be programmed around term dates.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Don’t leave trays and floors sitting wet
  • Clean sealant with gentle products and a soft cloth
  • Leave signs up until the cure time is over
  • Note failing joints building by building

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

Signs you need washroom sealing in Chichester

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

Look out for the following:

  • A new bead over an old one coming away
  • Failed sealant behind washroom basins
  • Users noticing mouldy joints
  • Mould spotting along silicone joints

Office toilets at parks like City Business Park (to the south of Chichester) take steady weekday use, and mouldy silicone soon shows.

What your quote should include

  • The terms of the workmanship guarantee
  • Is the sealant right for the movement and the substrate?
  • What site paperwork they can supply
  • How the joint faces will be prepared and primed
