Commercial sealant for Longmoor homes and businesses

For landlords and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

Commercial sealant in Longmoor

Commercial work is planned around the building, not the other way round. We can work room by room, floor by floor or in batches, and out-of-hours work or early starts can be arranged where it helps. Common call-outs are for whole floors of tired en suites and leaks from showers into rooms or ceilings below, on welfare facilities, student & care accommodation and hotel bathrooms.

Work in a small place like Longmoor is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Longmoor: your questions answered

Is Longmoor in your area for commercial sealant?

Yes. Our work covers London and the South East, and Longmoor is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.

Is Longmoor within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

How long will you be here?

As a guide, most jobs take a few hours for a single washroom, longer for a whole building. Larger jobs naturally take longer.

Can you match the sealant colour?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Can you reseal every bathroom in a hotel?

Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.

Can the hotel stay open while you work?

Yes. Each visit covers an agreed batch of rooms.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

What happens if it’s left?

Sealing over the old bead can seem the fastest option, but it won’t bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. Around Longmoor, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

How we quote for commercial sealant

There’s no set price list, because jobs vary so much. The quote depends on:

  • The number and length of the joints
  • Mould in or behind the old joints
  • How easy the joints are to reach
  • The old material and how stubborn it is

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

Photos by email are helpful but not essential. Please mention:

  • If someone has resealed it before
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel
  • Pictures of the joints, sent by email

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or drop us an email.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Add sealant to your planned maintenance checks
  • Keep a record of which rooms were resealed and when
  • Get split or lifting joints looked at early
  • Leave squeegees in busy showers

Each room is handed back with its cure time, which is usually around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.

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

Commercial sealant in Longmoor: local notes

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a building such as Greatham Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Letting a property close to Liss station? Then several rental properties can be resealed on one programme.

How it works

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a single washroom, longer for a whole building. Somewhere like Longmoor needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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. Old sealant is cut out room by room and joints 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.

Getting ready for the visit

  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in

What we can’t put right

In fairness, there are a few things sealant will not fix:

  • Assessing what fire stopping a building needs
  • Cracked trays or baths rather than failed joints
  • Tiles coming off the wall

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Joints and surfaces we work on

  • Rental portfolios
  • Retail & leisure sites
  • Hotel bathrooms
  • Office washrooms & kitchens
  • Welfare facilities
  • Student & care accommodation

Surface by surface

Welfare facilities

Before a health and safety visit or audit, tired sealant is easy to sort. Let us know when it needs to be done and we’ll schedule around it, cure time included.

Student & care accommodation

Many accommodation blocks have rows of similar en suites. A room-by-room programme keeps the job efficient.
