Commercial sealant in Covent Garden, done properly

Staff facilities can’t 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 office washrooms & kitchens, rental portfolios and welfare facilities, and the jobs we see most are water marks on ceilings under bathrooms and washrooms that need sorting before an inspection.

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 Covent Garden, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

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

How the job changes by surface

Hotel bathrooms

We can plan around check-out and check-in times, with the order agreed with your team.

Rental portfolios

Landlords and agents can have several properties resealed in one programme.

Common problems we fix in Covent Garden

Larger buildings move, and lightweight partitions flex more than masonry. The sealant between walls, trays and fittings absorbs that strain.

Look out for these signs:

  • Worktop sealant that has shrunk and stained
  • Silicone laid over old silicone by a previous contractor
  • Shower leaks reaching the floor below
  • Failed floor-level joints in accessible wet rooms

For landlords with property near London Charing Cross station, we can quote for one property or a whole portfolio of rentals.

Questions to ask before you book

  • How much experience the applicator has
  • Which sealant they’ll use, and why
  • How the colour is chosen
  • How long to leave it before use

Our hiring checklist

Common questions in Covent Garden

Do you work for landlords with property near London Charing Cross station?

Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Do you work for hotels and guest houses in Covent Garden?

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do you offer different sealant colours?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before we start.

How much does commercial sealant cost in Covent Garden?

It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and let us know what needs doing and where.

Is the work guaranteed?

Yes. Every job comes with our 12-month guarantee.

Can you send RAMS and insurance details for our site?

Let us know your site’s requirements. We’ll confirm what we can supply before work is booked.

Why it’s worth doing now in Covent Garden

A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Why us?

  • Arbo and Everbuild products
  • Sealant colour chosen to suit
  • Over 20 years’ experience
  • Every job guaranteed for a year

Commercial sealant around Covent Garden

London’s water is hard, so limescale builds up on sealant, grout and fittings. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Covent Garden is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Schools such as St Clement Danes CofE Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Covent Garden is about 1 mile east of City of Westminster, in Greater London. If you need commercial sealant in Covent Garden, please ring 0345 464 0079 or email us for a quick quote.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

We also work for property managers and facilities teams in Covent Garden and across Greater London. Several sites can go on one quote, and we are fully insured.

When it is not the sealant

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • A shower tray, bath or basin that is cracked or broken
  • Tiles coming off the wall
  • Faulty shower valves and leaking traps

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Surfaces we seal

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

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per area, with larger sites planned over several visits. In Covent Garden, 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. First we visit and agree the scope, the sequence and the working hours.
  2. Every area is sheeted and the old silicone stripped out.
  3. The joints are degreased, treated and left to dry.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Each room is checked and handed back with its cure time.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • On commercial sites, let us know about site rules
  • Move anything stored near the joints
