Floor joint sealing in Foxbury

Floor joint sealing in Foxbury, done properly

Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we close it with a flexible sealant instead. We are often asked to deal with gaps opening between the floor and skirting and threshold joints that have opened or worn, on skirting boards, concrete floor joints and tiled floors.

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 failed shower seals, open skirting joints and gaps at thresholds are typical.

A one-year guarantee comes as standard.

How the job changes by surface

Commercial floors

Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.

Tiled floors

Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines.

The process

There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours, depending on the length of joint. In a London area like Foxbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We look at the gap and the floor type and agree the right sealant.
  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. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on
  • Mention any parking rules near the property

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Keep caulk for dry, still joints only
  • Check skirting joints after the heating season
  • Act on grout cracks that run in a straight line
  • Cone off fresh joints until they’re ready

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it until it’s ready.

In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.

Why it’s worth doing now in Foxbury

Dirt builds up in open joints and makes the floor look worn. Sealed joints are easier to keep clean and finishes the floor. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Foxbury.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Signs you need floor joint sealing in Foxbury

Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water, which is why so many skirting joints look broken.

Look out for any of the following:

  • Gaps between floors and kitchen plinths
  • Perimeter joints in tiled floors filled with grout
  • Threshold joints that have opened or worn
  • Cracked caulk along skirting in bathrooms and kitchens

Foxbury is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Common questions in Foxbury

Is Foxbury in your area for floor joint sealing?

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

Do you work for landlords with property near Sidcup station?

Yes, we work for landlords and agents. 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 any work starts.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Can you add a movement joint to a tiled floor?

In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Are you fully insured?

Yes. We’re fully insured.

Can you match the sealant colour?

In most cases you can choose. We will explain which colours are available and agree one before work begins.

Do you work on commercial floors?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we’ll quote.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Joints and finishes in Foxbury homes

Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. 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 Sidcup station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Community buildings like Christ Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
