What we do, step by step

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes anything from a few hours to several days, depending on the number of rooms. For a village or hamlet like Steel Cross, the journey is planned in advance: let us know about lanes, gates and parking. 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. 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. Rooms are handed back in order, each with its cure time.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Let us know if you’ve seen damp or leaks

Your questions about commercial sealant in Steel Cross

Is Steel Cross in your area for commercial sealant?

Yes, Steel Cross is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

Is Steel Cross within the area you cover?

Yes, Steel Cross is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

What do you need from me for a quote?

A short description and the location, plus photos if you have them. We will ask anything else we need to know.

Do you provide RAMS?

We are fully insured, so start by telling us what your site asks for. Send over your requirements and we’ll confirm what we can provide.

Is there any odour?

There can be a smell while the sealant cures. Ventilation helps.

Will the old sealant be removed?

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

Surface by surface

Rental portfolios

Landlords and agents can have several properties resealed in one programme and each property booked in when it’s empty or convenient.

Office washrooms & kitchens

In staff kitchens, we degrease joints before resealing, using a food-safe sealant by sinks where it’s needed.

How we quote for commercial sealant

We quote each job individually. These are the things that affect it:

  • Any mould that needs treating
  • How easy the joints are to reach
  • The number of rooms or windows
  • The product the joint needs

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Helping us quote

To make quoting easier, let us know:

  • Any previous sealing or DIY work
  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel
  • How many joints, rooms or windows are involved

To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.

Keeping the joints in good condition

Looking after new joints is easy:

  • Get split or lifting joints looked at early
  • Note the date each area was done
  • Leave squeegees in busy showers
  • Add sealant to your planned maintenance checks

Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix.

Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

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.

Work for landlords, hotels and businesses

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Leave it or put it right?

Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Older cottages and farmhouses around Steel Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Why Steel Cross clients choose us

  • We never seal over old sealant
  • 12-month guarantee on every job
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Full insurance on every job

Commercial buildings in Steel Cross

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

Community buildings like The Parish Church of All Saints are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. If you let a flat or house near Crowborough station, several rental properties can be resealed on one programme. If you look after a building such as Beacon Academy, washroom and kitchen sealant can be programmed around term times or opening hours.
