Floor joint sealing in Winchester

Surface by surface

Concrete floor joints

We clean concrete joints out thoroughly before sealing. Backing goes in where the depth needs controlling.

Skirting boards

If the skirting is painted, a paintable flexible sealant works well. In wet rooms and kitchens, silicone is generally better.

Floor joint sealing for homes and businesses in Winchester

Across Winchester, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. If you’re dealing with failed seals where bathroom floors meet baths and panels and skirting that has pulled away from the floor, we can help, on concrete floor joints, wet room & bathroom floors and thresholds alike.

Winchester is big enough to have new developments going up alongside its older streets. Snags in sealant and floor joints often show in a new home’s first year or two.

Big or small, it’s backed by our one-year guarantee.

Common problems we fix in Winchester

Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.

It’s worth asking for a quote if you see:

  • Skirting that has pulled away from the floor
  • Concrete floor joints that have broken down
  • Threshold joints that have opened or worn
  • Cracked grout where a tiled floor needs a movement joint

If you look after a building such as St Bede Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Before you book anyone

  • What insurance they hold
  • How the joint is cleaned and prepared
  • What product goes in the joint
  • What the cure time is

Our hiring checklist

Aftercare tips

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

  • Don’t paint over silicone
  • Keep floor cleaning water to a minimum at the edges
  • Have a cracking tiled floor checked before tiles break
  • Lift furniture rather than dragging it across joints

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.

A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.

What sealant work cannot fix

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

  • Movement too big for a sealant joint
  • Cracked or broken concrete slabs
  • Floors that are uneven or need levelling

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

DIY versus a professional finish

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Joints and finishes in Winchester homes

Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as St Swithun-upon-Kingsgate Church, joints in its floors, skirtings and thresholds need resealing as they wear. For landlords with property near Winchester station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

What happens on the day

We keep the work tidy and contained to the joints we are treating. Expect the work to take a morning or an afternoon for most homes, and we tell you how long to leave it before we go. Jobs in a place the size of Winchester range from town-centre flats to offices and family homes. For each, it helps to know about access, parking and where the joints are.

  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. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
