One point of contact handles commercial sealant work in Rowsham from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. For work around Rowsham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use

Aftercare for building managers

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

  • Keep washrooms out of use until we say the sealant has cured
  • Tell us about infection-control or permit rules before we quote
  • Don’t leave an open joint at a basin or tray
  • Include joints in routine washroom inspections

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Do you need washroom sealing in Rowsham?

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

Typical triggers for a call:

  • Sealant stained black around basins and showers
  • Users noticing mouldy joints
  • Split or peeling sealant at shower trays
  • Resealing that didn’t last because the old bead stayed

Church halls and community buildings, such as those at Church of All Saints, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

What your quote should include

  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?

Office washrooms on sites such as Upper Wingbury Farm Business Village (2.1 miles north-east of Rowsham) are in use all working day, so resealing is phased to keep some open.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Condensation from failed extract fans
  • Hollow tiles or loose panels behind the joint

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

Where we work in Rowsham

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

Questions about Rowsham

Could you schedule work at a campus like University Campus Aylesbury Vale for the vacation?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is hospital work, at somewhere like Tindal Centre, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

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

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Can weather delay the job?

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. Internal work is far less affected.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
