Floor joint sealing near Knox Bridge

Floor joint sealing in Knox Bridge

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We work on skirting boards, commercial floors and thresholds, and common reasons people get in touch are skirting that has pulled away from the floor and failed seals where bathroom floors meet baths and panels.

Somewhere as small as Knox Bridge, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.

Every job comes with our one-year guarantee.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Get cracks along tile grout lines looked at early
  • Don’t paint over silicone
  • Avoid caulk in bathrooms and kitchens
  • Lift furniture rather than dragging it across joints

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed until it’s ready.

A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

What happens on the day

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a morning or an afternoon for most homes, including the tidy-up. For a village or hamlet like Knox Bridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Before we arrive

  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work

What floor joint sealing looks like in Knox Bridge

Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

If you let a flat or house near Staplehurst station, gaps at skirtings and thresholds are worth sealing between tenancies. In and around Knox Bridge, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.

What affects the cost of floor joint sealing

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

  • The number and length of the joints
  • Whether the work is at height
  • Any working-time requirements on site
  • Any mould that needs treating

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

What we need to know

There’s no need for technical detail. Just tell us:

  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • Whether it’s a home or a business

Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job, and photos are welcome.

What the job involves on each surface

Skirting boards

If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges.

Common questions in Knox Bridge

Is Knox Bridge in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Knox Bridge is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Do you cover smaller places like Knox Bridge?

Yes. Knox Bridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What causes gaps between the floor and skirting?

Generally it’s movement: heating drying the timber, or a filler that is too rigid. A flexible sealant stays closed as the floor moves.

I’m a tenant. Can you help?

Yes. Check with your landlord; we can send the quote to them too.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Where do you work from?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.
