Floor joint sealing in Bexley

Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant. If you have open gaps along the bottom of skirting boards and grout cracking in a straight line across a floor, we can put it right.

Much of London’s new housing is flats 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.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Quotes for floor joint sealing in Bexley

Call for a quick quote. The main things that affect it are:

  • When we can work, for business premises
  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • The problem you’ve noticed
  • A few photos by email, if you can
  • If someone has resealed it before
  • Any access issues, like height or stairs

Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details, and pictures are welcome.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

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

How the job changes by surface

Wet room and bathroom floors

Bathroom floors meet baths, trays, panels and skirting. They’re sealed with a flexible, anti-fungal silicone to keep water out of the edges.

Tiled floors

Large or heated tiled floors need room to move. We replace grout with flexible sealant along the right lines coloured to suit.

Floor joint sealing around Bexley

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. 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 is why the skirting and threshold joints need a flexible seal.

Schools such as Old Bexley Church of England School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. As a London address, Bexley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Community buildings like Parish Church of St John the Evangelist are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

How to look after the new joints

After the cure time, these simple habits help:

  • Use a well-wrung mop rather than flooding the floor
  • Keep heavy wheels off new concrete joints until cured
  • Don’t paint over silicone
  • Do not slide heavy items over sealed joints

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

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

Leave it or put it right?

Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant moves with the floor. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Bexley, the repair is bigger than a sealant job.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

  • Trusted Arbo and Everbuild sealants
  • We agree the colour with you first
  • Experience in homes, commercial sites and hotels
  • We leave the area clean and tidy

See our cost guide or what customers say.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on the length of joint, including the tidy-up. In Bexley, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied.
  5. Finally, we check the work and talk you through aftercare.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area
  • Move anything stored near the joints
