Floor joint sealing in Stockwell, done properly

Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. If you have chipped and open joints in warehouse floors and caulk that has cracked where the floor moves, we can help, whatever the surface.

New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

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

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

What we cannot put right

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Damaged concrete that needs breaking out and repairing
  • Movement too big for a sealant joint
  • Loose, hollow or cracked tiles, which need a tiler

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Where we work in Stockwell

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

How the visit works

At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a morning or an afternoon for most homes, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints

Where are you based?

Can I choose the sealant colour?

Normally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

Will you leave a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Why does the gap under my skirting keep coming back?

It’s normally the floor moving: heating drying the timber, or a filler that is too rigid. A flexible bead keeps up with the movement.

Joints and finishes in Stockwell homes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

Stockwell is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Brixton station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as St. Andrew's, floor and skirting joints in halls and kitchens wear like any others.

What affects the cost of floor joint sealing

Some jobs are bigger than they look, and some smaller. The main factors:

  • The size of the job
  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is
  • Whether there’s mould to deal with

We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

What to tell us for a quote

What to tell us when you ask for a quote:

  • The problem you’ve noticed
  • Photos by email, if that is easy
  • Whether it has been sealed before
  • The address or postcode of the job

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

Why deal with it now?

The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. 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 Stockwell.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Sweep along the edges of the floor
  • Keep caulk for dry, still joints only
  • Ask before painting over a sealed joint
  • Cone off fresh joints until they’re ready

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.

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