How we handle commercial sealant in Herne Bay

We fit the work around your building. We can work room by room, floor by floor or in batches, and early starts or out-of-hours working can be arranged where it helps. Typical jobs include leaks from showers into rooms or ceilings below and split sealant where wet room floors meet walls, across welfare facilities, office washrooms & kitchens and retail & leisure sites.

If you look after a school, care home, pub or office in Herne Bay, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Work can be planned around opening hours where needed.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Surface by surface

Office washrooms & kitchens

Office washrooms and tea points are used all day, so we can work early or out of hours where that can be arranged. Basins, urinals, worktops and sinks are all resealed.

Hotel bathrooms

We can plan around check-out and check-in times, with the order agreed with your team.

For landlords and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Herne Bay questions

Can you do commercial sealant in Herne Bay?

Yes, Herne Bay is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Do you work for landlords with property near Herne Bay station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

How long will you be here?

A typical job takes a few hours per room, so whole buildings are phased, including the preparation. We will confirm how long when we quote.

Can you start early or work out of hours?

That can be arranged for many jobs. We’ll confirm the working hours with your quote.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Do you take on large, multi-room jobs?

Yes. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.

How soon can a room be used after resealing?

Normally after around 24 hours. We give a cure time for each area.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

What happens if it’s left?

Sealant work is quick by the room: the job takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Around Herne Bay, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Combining jobs into one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

What commercial sealant looks like in Herne Bay

If you run a hotel, guest house or holiday let in a coastal place like Herne Bay, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

If you let a flat or house near Herne Bay station, sealant work can be quoted for a single flat or a whole portfolio. If you look after a church, hall or community building such as Christ Church, any kitchen and washrooms need the same sealant care as any other building. Schools such as Herne Bay Junior School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Quotes for commercial sealant in Herne Bay

Your quote is based on your job. We look at:

  • The type of sealant required
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • The amount of work

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • The type of property
  • Photos by email, if that is easy
  • If someone has resealed it before
  • Any access issues, like height or stairs

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Book larger programmes for quieter times of year
  • Add sealant to your planned maintenance checks
  • Leave squeegees in busy showers
  • Do not leave a failed joint until the next refurbishment

A squeegee in each shower is a simple help: less water sits on the joints between uses.

Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.

How the visit works

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a morning for a small washroom, and a planned programme for bigger sites, and we tell you how long to leave it before we go. For a job in Herne Bay, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. In each room, the old bead comes out and the joint is cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Rooms are handed back in order, each with its cure time.

Getting ready for the visit

  • Mention any parking rules near the property
  • Mention any tricky access
  • Where the joints are inside, avoid wetting them before we arrive
