Trusted floor joint sealing in Upper Clapton

Floor joint sealing in Upper Clapton

Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side so the joint stays neat. If you’re dealing with grout used at the floor edge instead of sealant and open joints around bathroom floor edges, we can put it right.

London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

Whatever the size of the job, it’s backed by our one-year guarantee.

Different surfaces, different methods

Skirting boards

Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the bead sits on a clean surface.

Thresholds

Two different floors meeting at a threshold move differently. We bridge them with a flexible bead.

Why deal with it now?

An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Upper Clapton, the repair is bigger than a sealant job.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Why book with us

  • Experience in homes, commercial sites and hotels
  • Over 20 years’ experience
  • Tidy, careful work
  • Every job guaranteed for a year

New homes and floors in Upper Clapton

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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

Managing a site like Harrington Hill Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Upper Clapton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Don’t paint over silicone
  • Keep dirt out of the joints
  • Have a cracking tiled floor checked before tiles break
  • Check skirting joints after the heating season

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.

In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.

What we cannot put right

Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:

  • Leaks from a failed tanking system
  • Floors that are uneven or need levelling
  • Damaged concrete that needs breaking out and repairing

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Surfaces we seal

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

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What we’re called out for in Upper Clapton

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting.

Common reasons people contact us include:

  • Open joints around bathroom floor edges
  • Gaps at thresholds between rooms
  • Chipped and open joints in warehouse floors
  • Dirt and water collecting in open floor joints

If you look after a church, hall or community building such as Church of St Thomas the Apostle, joints in its floors, skirtings and thresholds need resealing as they wear.

Our hiring checklist

How it works

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors. In Upper Clapton, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  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

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules
