What we do, step by step

On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a morning or an afternoon for most homes. For a village or hamlet like Crowmarsh Gifford, the journey is planned in advance: 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 clear the edges of the floor so the joints are easy to reach.
  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 smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Keep children and pets away from the work area
  • Mention any sign-in or site rules at work premises

Floor joint sealing in Crowmarsh Gifford, done properly

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints. If you have grout cracking in a straight line across a floor and cracked caulk along skirting in bathrooms and kitchens, we can help, on thresholds, commercial floors and skirting boards alike.

Older homes in small places like Crowmarsh Gifford often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

When can I walk on the floor?

When to call us in Crowmarsh Gifford

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands.

These are the problems we are asked about most:

  • Tiled floors with no room to move
  • Open joints around bathroom floor edges
  • Open gaps along the bottom of skirting boards
  • Dirt and water collecting in open floor joints

For buildings such as Church of St Mary Magdalene, joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Is the old sealant removed completely?
  • Who does the work, and how experienced they are
  • How long the guarantee is

How to look after the new joints

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

  • Ask before painting over a sealed joint
  • Have a cracking tiled floor checked before tiles break
  • Avoid caulk in bathrooms and kitchens
  • Mark off resealed joints in warehouses

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it until it’s ready.

Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.

What sealant work can’t fix

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

  • A tiled floor that needs relaying
  • Water getting under the tiles from elsewhere
  • Damaged concrete that needs breaking out and repairing

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

What we seal

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

Surface by surface

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk in a colour to suit.

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Why deal with it now?

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Around Crowmarsh Gifford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
