Floor joint sealing in Burn's Green

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

About our floor joint sealing in Burn's Green

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. We work on thresholds, concrete floor joints and wet room & bathroom floors, and common reasons people get in touch are gaps at thresholds between rooms and perimeter joints in tiled floors filled with grout.

In a village or hamlet like Burn'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.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Look at floor joints each spring
  • Lift furniture rather than dragging it across joints
  • Get cracks along tile grout lines looked at early
  • Use a well-wrung mop rather than flooding the floor

Avoid flooding the floor when you clean. Less water at the edges helps the joints last.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a morning or an afternoon for most homes. Somewhere like Burn's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  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

  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
  • Let us know about parking restrictions

New homes and floors in Burn'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.

Rented homes near Watton-At-Stone station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a building such as Benington Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Common questions in Burn's Green

Is Burn's Green in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Burn's Green is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

I let a flat near Watton-At-Stone station. Can you help?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Are you fully insured?

Yes. Full insurance covers our work.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

What causes gaps between the floor and 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.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Can you use decorators’ caulk instead?

Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.

My floor grout keeps cracking in a line. Can you help?

In many cases, yes. We replace the grout along a suitable line with flexible sealant coloured to suit. If tiles are loose, that needs fixing first.

When something else is needed

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

  • Structural movement or subsidence
  • Loose, hollow or cracked tiles, which need a tiler
  • Failed waterproofing under a wet room floor

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

What the job involves on each surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.

Skirting boards

Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing.

Common problems we fix in Burn's Green

An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap and can reach the subfloor.

Most people get in touch after spotting something like this:

  • Open gaps along the bottom of skirting boards
  • Perimeter joints in tiled floors filled with grout
  • Gaps at thresholds between rooms
  • Cracked grout where a tiled floor needs a movement joint

If you look after a church, hall or community building such as Parish Church of St Peter, floor and skirting joints in halls and kitchens wear like any others.
