Floor joint sealing for Canary Wharf homes and businesses

Joints and finishes in Canary Wharf homes

Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

For landlords with property near Canary Wharf station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. As a London address, Canary Wharf can be tricky for parking: let us know about parking bays, permits or a driveway.

How we handle floor joint sealing in Canary Wharf

Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant so water and dirt can’t get in. We’re often asked to deal with concrete floor joints that have broken down and open joints around bathroom floor edges, across concrete floor joints, tiled floors and thresholds.

New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

Our work is backed for twelve months, in Canary Wharf and everywhere else we cover.

Why act early in Canary Wharf

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a flat in Canary Wharf, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What happens on the day

Before we leave, we go over the finished joints with you. The work normally takes a morning or an afternoon for most homes, depending on the amount of work. For a job in Canary Wharf, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. We take out any old caulk, sealant or grout along the line.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Preparing for the visit

  • Let us know about parking restrictions
  • Keep children and pets away from the work area
  • Mention any leaks or damp you’ve noticed

When it is not the sealant

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

  • Leaks from a failed tanking system
  • Cracked or broken concrete slabs
  • Large cracks that need a surveyor

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

Surfaces we seal

  • Tiled floors
  • Skirting boards
  • Thresholds
  • Commercial floors
  • Concrete floor joints
  • Wet room & bathroom floors

What we are called out for in Canary Wharf

Caulk is the usual filler for skirting. It cracks where there’s movement or water.

Common reasons people contact us include:

  • Chipped and open joints in warehouse floors
  • Failed seals where bathroom floors meet baths and panels
  • Gaps opening between the floor and skirting
  • Tiled floors with no room to move

Community buildings like St Peter's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What to look for in a quote

  • Which colour the sealant will be
  • Whether VAT is included
  • What insurance they hold
  • Whether the sealant suits the joint

How soon can the floor be mopped?

You’ll get the times before we go. It depends on the sealant, and light foot traffic is generally fine before wet cleaning or wheels.

What the job involves on each surface

Thresholds

Two different floors meeting at a threshold move differently. A flexible sealant bridges them.

Skirting boards

If the skirting is painted, a paintable flexible sealant works well. In wet rooms and kitchens, silicone is generally better.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Vacuum floor joints regularly to stop grit building up
  • Check the sealant is paintable before decorating
  • Use furniture pads near skirting
  • Look at floor joints each spring

Follow the cure time before walking on or cleaning the joint. Light foot traffic is normally fine sooner than wet cleaning or wheels so we will give you each time.

A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and the edges sound.
