About our floor joint sealing in Sewardstonebury

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. We work on thresholds, commercial floors and skirting boards, and people most often call us about grout used at the floor edge instead of sealant and floor edges that trap water and grime.

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.

Our work is backed for twelve months.

How the job changes by surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint if it’s in the right place.

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.

When it is not the sealant

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Failed waterproofing under a wet room floor
  • Structural movement or subsidence
  • Tiles that have lifted or broken

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

Why deal with it now?

Left open, concrete joints break down under traffic. A sealed joint supports the edges. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Why book with us

The process

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the length of joint. In Sewardstonebury, 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. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • Keep children and pets away from the work area
  • Mention any tricky access
  • On commercial sites, let us know about site rules

Related advice

Do you need floor joint sealing in Sewardstonebury?

Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting.

Most people get in touch after spotting one of these:

  • Gaps between floors and kitchen plinths
  • Tiled floors with no room to move
  • Skirting that has pulled away from the floor
  • Cracked caulk along skirting in bathrooms and kitchens

For landlords with property near Chingford station, gaps at skirtings and thresholds are worth sealing between tenancies.

Our hiring checklist

Sewardstonebury: your questions answered

I let a flat near Chingford station. Can you help?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

Can you do floor joint sealing in Sewardstonebury?

Yes, Sewardstonebury is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

Are you insured?

Yes, we are fully insured.

Will there be a smell?

Sometimes, a little. It fades as the sealant cures.

Why has a gap opened under my skirting?

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.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Do you seal kitchen plinths to the floor?

Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone so water cannot get into the gap.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Floor joint sealing in Sewardstonebury: local notes

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

Managing a site like Yardley Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Sewardstonebury can be tricky for parking: let us know about parking bays, permits or a driveway.
