Commercial sealant in Crofton Park, done properly

In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. We’re often asked to deal with tired sealant ahead of a health and safety audit and too many rooms to reseal without closing the building, across office washrooms & kitchens, hotel bathrooms and retail & leisure sites.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Crofton Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What commercial sealant looks like in Crofton Park

Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. London’s water is hard, which leaves limescale on sealant, grout and taps.

As a London address, Crofton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Community buildings like Church of St Hilda are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

Quotes for commercial sealant in Crofton Park

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How easy the joints are to reach
  • How many areas need sealing
  • Any working-time requirements on site
  • The product the joint needs

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Helping us quote

To make quoting easier, let us know:

  • What’s wrong with the joints now
  • How we’d reach the joints
  • If someone has resealed it before
  • Where the job is, and your postcode

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

When it is not the sealant

It helps to know what we cannot do:

  • Tiles coming off the wall
  • A shower tray, bath or basin that is cracked or broken
  • Extraction that isn’t working, which needs an electrician or ventilation contractor

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

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

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take as long as the scope needs, from one welfare room to a full building. In Crofton Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before we start.
  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.

Preparing for the visit

  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
  • Move anything stored near the joints

Questions from Crofton Park

Can you help a landlord with a rental near Crofton Park station?

Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Is parking an issue for commercial sealant in Crofton Park?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done.

How long does commercial sealant take?

Typically it takes a morning for a small washroom, and a planned programme for bigger sites. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Do you take on large, multi-room jobs?

Yes. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

What we are called out for in Crofton Park

Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. The worktop and sink edges generally fail first.

The problems people normally mention when they call include:

  • Too many rooms to reseal without closing the building
  • Black, stained silicone in guest bathrooms
  • Washrooms that need sorting before an inspection
  • Leaks from showers into rooms or ceilings below

If you look after a building such as Stillness Infant School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What your quote should include

  • Whether VAT is included
  • Whether the sealant suits the joint
  • What guarantee comes with the work
  • Whether all the old sealant comes out first

Our hiring checklist

Why it’s worth doing now in Crofton Park

In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. That means a second room out of use and a repair to pay for. A reseal now avoids that. In a flat in Crofton Park, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • More than 20 years in sealant work
  • Full insurance on every job
  • We leave the area clean and tidy

Read our cost guide or our reviews.

How to look after the new joints

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

  • Don’t leave a failed joint until the next refurbishment
  • Leave squeegees in busy showers
  • Plan resealing around quiet periods
  • Keep a record of which rooms were resealed and when

Squeegees in guest and staff showers help: less water sits on the joints between uses.

Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
