Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Use mild cleaners on sealant, not bleach or abrasives
  • Keep a record of which rooms were resealed and when
  • Add sealant to your planned maintenance checks
  • Get split or lifting joints looked at early

Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.

Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Failed tanking or loose tiles behind the sealant
  • Assessing what fire stopping a building needs
  • Cracked trays or baths rather than failed joints

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

Workplaces and buildings in Falconwood

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Rented homes near Welling station change hands often, and sealant work can be quoted for a single flat or a whole portfolio. If you look after a church, hall or community building such as Bishop Ridley Church, its kitchen and washroom sealant needs looking after like anywhere else.

Different surfaces, different methods

Retail & leisure sites

Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. We can plan around opening hours.

Rental portfolios

Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.

Landlord and commercial work in Falconwood

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

The process

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for a single washroom, longer for a whole building, depending on the amount of work. In Falconwood, 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. We start by looking at the rooms and agreeing what’s needed.
  2. We agree when we will work, with early or out-of-hours slots where they 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.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Mention any tricky access
  • Clear the area around the work

What we are called out for in Falconwood

A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. So the silicone ages faster than it would at home.

Look out for any of the following:

  • Rental bathrooms that need resealing between tenants
  • Leaks from showers into rooms or ceilings below
  • Failed floor-level joints in accessible wet rooms
  • Failed joints in office kitchens and tea points

Managing a site like Bishop Ridley Church of England VA Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

Questions to ask before you book

  • How long the guarantee is
  • Is VAT in the price?

10 questions to ask before you book

Why act early in Falconwood

Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we’ll say so. In a flat in Falconwood, 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.

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