Floor joint sealing in Steyning

We seal floor joints in homes, offices and commercial buildings across Steyning. We start by checking the floor type and the joint, because the right sealant depends on both. Common call-outs are for gaps opening between the floor and skirting and tiled floors with no room to move, on wet room & bathroom floors, thresholds and skirting boards.

In smaller places like Steyning, 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.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

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

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.

What happens on the day

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most rooms, longer for large commercial floors. For a job in Steyning, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Ask before painting over a sealed joint
  • Use a well-wrung mop rather than flooding the floor
  • Act on grout cracks that run in a straight line
  • Check skirting joints after the heating season

Keep heavy furniture from dragging across the joints. Dragging can tear the bead especially in the first few days.

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.

Floor joint sealing in Steyning: local notes

Floors around West Sussex run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

For landlords with property near Lancing station, gaps at skirtings and thresholds are worth sealing between tenancies.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Common problems we fix in Steyning

Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open.

People generally contact us after spotting one of these:

  • Chipped and open joints in warehouse floors
  • Threshold joints that have opened or worn
  • Open joints that fill with dirt
  • Cracked caulk along skirting in bathrooms and kitchens

If you look after a building such as Steyning CofE Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What affects the cost of floor joint sealing

There’s no set price list, because jobs vary so much. The quote depends on:

  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove
  • The size of the job
  • Mould in or behind the old joints

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

What to tell us for a quote

To make quoting easier, let us know:

  • Any previous sealing or DIY work
  • Any access issues, like height or stairs
  • A few photos by email, if you can
  • Roughly how big the job is

There’s no standard price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
