How we handle commercial sealant in Rowlands Castle

In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. If you have water marks on ceilings under bathrooms and whole floors of tired en suites, we can put it right, whatever the surface.

Community buildings, schools and small businesses around places like Rowlands Castle have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How it works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single washroom, longer for a whole building. For a job in Rowlands Castle, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We walk the site with you and agree the rooms, the order and the hours.
  2. Each area is protected and the old sealant cut out completely.
  3. The joints are degreased, treated and left to dry.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Each room is checked and handed back with its cure time.

Before we arrive

  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints

Advice

What happens if it’s left?

First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and cleaning rarely puts it right. Replacing it does. Homes in smaller places like Rowlands Castle can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What do you need from me for a quote?

Tell us what needs doing and where. If we need more, we will ask.

Looking after it afterwards

A little care helps the new joints last. Our advice:

  • Report broken fans quickly
  • Pass on the cure time to whoever cleans the rooms
  • Put a squeegee in each shower
  • Schedule work around occupancy

Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that is what keeps mould away.

Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Tiles coming off the wall
  • A broken extractor fan behind the mould problem
  • Leaking pipework, valves or wastes (a plumber’s job)

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

When to call us in Rowlands Castle

Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. If a tray flexes, the sealant around it splits.

People usually contact us when they notice something like this:

  • Black, stained silicone in guest bathrooms
  • Silicone laid over old silicone by a previous contractor
  • Large numbers of bathrooms needing the same work
  • Mouldy bathrooms flagged at a tenancy check

Community buildings like The Church on the Green are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.
