Floor joint sealing near Millbank

Floor joint sealing in Millbank, done properly

Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant and stops dirt collecting. We work on wet room & bathroom floors, skirting boards and concrete floor joints, and people most often call us about perimeter joints in tiled floors filled with grout and open joints around bathroom floor edges.

Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

Every job comes with our 12-month guarantee.

Why deal with it now?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Millbank, the repair is bigger than the sealant job would have been.

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 make a difference, and we will explain the quote if you ask.

Why Millbank customers choose us

  • Over 20 years’ experience
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Any old sealant cut out fully, not covered over
  • Domestic, commercial and hotel work

Floor joint sealing around Millbank

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.

If you let a flat or house near London Victoria station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Community buildings like Christ Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Wet room and bathroom floors

Wet room floors rely on sound joints at the walls. It’s resealed with a sanitary silicone.

Signs you need floor joint sealing in Millbank

Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.

These are the problems we’re asked about most:

  • Tiled floors with no room to move
  • Open joints that fill with dirt
  • Failed seals where bathroom floors meet baths and panels
  • Worn sealant at door thresholds

Your questions about floor joint sealing in Millbank

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

Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

Can you do floor joint sealing in Millbank?

Yes. We work across London and the South East, and Millbank is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Do the sealants smell?

Possibly a little. It fades as the sealant cures.

Can sealant along the skirting be painted?

If you tell us beforehand, yes. Joints that will be painted get a paintable product and wet areas get silicone.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Honest limits

We won’t take on work that won’t last, so these are the limits:

  • Damaged concrete that needs breaking out and repairing
  • Bouncy or failing floorboards
  • Tiles that have lifted or broken

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on the length of joint. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Check the sealant is paintable before decorating
  • Keep floor cleaning water to a minimum at the edges
  • Act on grout cracks that run in a straight line
  • Keep caulk for dry, still joints only

Avoid flooding the floor when you clean. Less water at the edges helps the joints last.

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.

What affects the quote in Millbank

For a quick quote, just ask. What matters most is:

  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with
  • Access and height
  • How many areas need sealing

Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Asking for a quote

When you contact us, it’s useful to know:

  • The rough size of the job
  • Access, such as stairs, a lift or height
  • Pictures of the joints, sent by email
  • The problem you’ve noticed

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
