Commercial sealant in Knockholt Pound, done properly

Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. We work on rental portfolios, hotel bathrooms and student & care accommodation, and common reasons people get in touch are failed floor-level joints in accessible wet rooms and leaks from showers into rooms or ceilings below.

In a village or hamlet like Knockholt Pound, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Knockholt Pound: your questions answered

Will you come out to Knockholt Pound?

Yes, Knockholt Pound is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work for landlords with property near Knockholt station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access.

Can you take on a whole building?

Yes. After a site walk, we agree the scope and sequence, and you get one clear quote.

Can you work outside opening hours?

In many cases. Let us know when the building is quietest, and we will plan the work around them.

Can you work around guests in a hotel?

Yes. Rooms are done a few at a time, keeping most rooms available. Each room comes back with its cure time for housekeeping.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Quotes for commercial sealant in Knockholt Pound

Jobs vary more than people expect. What affects the quote:

  • The number and length of the joints
  • Mould in or behind the old joints
  • Which sealant suits the joint
  • The old material and how stubborn it is

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • If it’s domestic, commercial or a hotel
  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • Whether it has been sealed before

There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Leave it or put it right?

A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. Around Knockholt Pound, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What the job involves on each surface

Retail & leisure sites

Shops, gyms, leisure centres and restaurants all have joints that need sealing. Work can be arranged outside opening hours where that is possible.

Student & care accommodation

Care homes need careful planning around residents, and staff are told when each bathroom can be used.

Do you need commercial sealant in Knockholt Pound?

A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.

People normally contact us when they notice something like this:

  • Joints that need doing before an inspection or audit
  • Too many rooms to reseal without closing the building
  • Leaks from showers into rooms or ceilings below
  • Split sealant where wet room floors meet walls

Managing a site like Halstead Community Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

What to look for in a quote

  • Whether they’re fully insured
  • What happens if they find a problem under the old sealant
  • How much experience the applicator has
  • What the cure time is

Choosing a sealant specialist

What happens on the day

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the number of rooms. For a village or hamlet like Knockholt Pound, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Each finished area is checked with you and given a cure time.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us if parking is tricky
  • Let us know if you’ve seen damp or leaks

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Get split or lifting joints looked at early
  • Keep strong chemicals and scourers off the joints
  • Book larger programmes for quieter times of year
  • Keep a record of which rooms were resealed and when

Each room is handed back with its cure time, generally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.

Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
