Keeping the joints in good condition

Aftercare is simple:

  • Get split or lifting joints looked at early
  • Put a squeegee in each shower
  • Ask cleaners to go gently on the silicone
  • Keep a record of which rooms were resealed and when

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

Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.

How we handle commercial sealant in Fitzrovia

Staff facilities cannot be out of action for long. Early starts and out-of-hours work can be arranged to keep disruption down. Each area is handed back with its cure time. We work on rental portfolios, retail & leisure sites and student & care accommodation, and the jobs we see most are tired sealant in let properties and leaks from showers into rooms or ceilings below.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Fitzrovia.

Big or small, it’s backed by our 12-month guarantee in Fitzrovia and across Greater London.

Fitzrovia questions

Do you work in hotels near Fitzrovia?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Do you work for landlords with property near London Euston station?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints.

Does someone need to be in?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

Where are you based?

Our base is in Crawley, and we work across South East England, London and Scotland.

Do you provide RAMS?

Let us know your site’s requirements. We will confirm what we can provide alongside the quote.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and you will get one quote.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Commercial buildings in Fitzrovia

London’s water is hard, which leaves limescale on sealant, grout and taps. Fitzrovia has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Managing a site like All Souls CofE Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours. As a London address, Fitzrovia can be tricky for parking: let us know about parking bays, permits or a driveway. For buildings such as Whitefield's Tabernacle, halls and community kitchens see heavy use, and their sealant shows it.

Fitzrovia is about 1 mile north-east of Marylebone, in Greater London. Anywhere in NW1W, we cover commercial sealant for homes and businesses. Across Greater London, we cover 764 places, Fitzrovia among them.

How the visit works

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a morning for a small washroom, and a planned programme for bigger sites for a typical job. In Fitzrovia, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. The first visit is a look round the site to agree the scope.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Once dry, every joint is resealed and tooled.
  5. We let your team know the cure time for every area.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Move anything stored near the joints
  • Mention any tricky access

Related advice

Should I try it myself first?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Leave it or put it right?

Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

How we quote for commercial sealant

Jobs vary more than people expect. The main factors:

  • The old material and how stubborn it is
  • Whether the work is at height
  • How many areas need sealing
  • Which sealant suits the joint

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

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The rough size of the job
  • Photos by email, if that is easy
  • Whether it’s a home or a business
  • The problem you’ve noticed

For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. We’ll give you a clear quote before any work starts.

What the job involves on each surface

Welfare facilities

Welfare facilities, shower rooms and changing areas need to stay usable. We can plan the work in sections so part of the facilities stays in use.

Retail & leisure sites

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

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too in Fitzrovia and across Greater London. Several sites can be quoted together, and we are fully insured for the work.

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.
