Floor joint sealing in Todd's Green

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. We’re often asked to deal with rigid edge joints in tiled floors and open gaps along the bottom of skirting boards, on wet room & bathroom floors, concrete floor joints and tiled floors.

In a village or hamlet like Todd's Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Every job comes with a one-year guarantee.

How the visit works

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors from start to finish. Somewhere like Todd's Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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 vacuumed clean, with backing fitted wherever depth matters.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  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

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Floor joint sealing around Todd's Green

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

For buildings such as Church of St Mary the Virgin, joints in its floors, skirtings and thresholds need resealing as they wear. If you look after a building such as The John Henry Newman School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What affects the cost of floor joint sealing

The price is agreed before any work begins. It takes into account:

  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • Access and height
  • Mould in or behind the old joints

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Asking for a quote

What to tell us when you ask for a quote:

  • Photos by email, if that is easy
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height
  • Any previous sealing or DIY work

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How the job changes by surface

Tiled floors

Large or heated tiled floors need room to move. We replace grout with flexible sealant along the right lines in a matching colour.

Skirting boards

Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking painted or coloured to match.
