How we handle floor joint sealing in Sundridge

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt can’t get in. We work on wet room & bathroom floors, commercial floors and tiled floors, and the jobs we see most are rigid edge joints in tiled floors and caulk that has cracked where the floor moves.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

Each job carries a 12-month guarantee, large or small.

What we do, step by step

The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a morning or an afternoon for most homes, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Sundridge. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits the floor.
  5. The joint is tooled neatly and the cure time explained.

How to prepare

  • Tell us if parking is tricky
  • Let us know about earlier repairs to the joints
  • Clear items away from the joints we are working on

Floor joint sealing around Sundridge

Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

If you look after a church, hall or community building such as St Andrew, floor and skirting joints in halls and kitchens wear like any others. Managing a site like St Joseph's Catholic Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Leaks from a failed tanking system
  • Subfloor problems that need a flooring contractor
  • Concrete repairs beyond the joint

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What we seal

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

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Have a cracking tiled floor checked before tiles break
  • Keep heavy wheels off new concrete joints until cured
  • Use furniture pads near skirting
  • Don’t paint over silicone

Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.

What we are called out for in Sundridge

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges until the joint widens.

The problems people normally mention when they call are:

  • Gaps between floors and kitchen plinths
  • Cracked caulk along skirting in bathrooms and kitchens
  • Tiled floors with no room to move
  • Concrete floor joints that have broken down

If you let a flat or house near Sundridge Park station, gaps at skirtings and thresholds are worth sealing between tenancies.

Questions to ask before booking

  • What insurance they hold
  • What the cure time is
  • What guarantee comes with the work
  • What happens if the job turns out different

Our hiring checklist

Should I try it myself first?

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.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Your questions about floor joint sealing in Sundridge

Is parking an issue for floor joint sealing in Sundridge?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you work for landlords with property near Sundridge Park station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Will I be able to paint over the new joint?

Where you plan to paint, we do. Silicone does not take paint.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

My floor grout keeps cracking in a line. Can you help?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

Are you fully insured?

Yes, we are fully insured.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How we quote for floor joint sealing

Call for a quick quote. What matters most is:

  • The type of sealant required
  • The number and length of the joints
  • How many areas need sealing
  • The old material and how stubborn it is

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Helping us quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • Photos by email, if that’s easy
  • If it’s domestic, commercial or a hotel

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
