Floor joint sealing in Locks Heath, done properly

Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone. If you have skirting caulk that keeps splitting and grout used at the floor edge instead of sealant, we can put it right, whatever the surface.

In smaller places like Locks Heath, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Keep dirt out of the joints
  • Keep caulk for dry, still joints only
  • Don’t paint over silicone
  • Look at floor joints each spring

Silicone sealant is not made to take paint. If you plan to paint, we’ll use a paintable product.

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the surface smoother.

For landlords and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

How the job changes by surface

Commercial floors

Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work where it’s needed.

Concrete floor joints

Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.

What floor joint sealing looks like in Locks Heath

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 building such as Park Gate Primary School, entrance and corridor floor joints take a lot of traffic. If you let a flat or house near Swanwick station, gaps at skirtings and thresholds are worth sealing between tenancies.

What we are called out for in Locks Heath

Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.

Any of these means the joints need attention:

  • Threshold joints that have opened or worn
  • Perimeter joints in tiled floors filled with grout
  • Failed seals where bathroom floors meet baths and panels
  • Open joints that fill with dirt

For buildings such as St John, floor and skirting joints in halls and kitchens wear like any others.

How the visit works

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the length of joint. For a job in Locks Heath, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Clear items away from the joints we’re working on
  • Keep pets and children clear of the area while we work

Advice

Leave it or put it right?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job for most homes. Homes in smaller places like Locks Heath can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.

Why book with us

  • A choice of colours where the product allows
  • We leave the area clean and tidy
  • Any old sealant cut out fully, not covered over
  • We agree the colour with you first
