Floor joint sealing for Dunsbury homes and businesses

Floor joint sealing in Dunsbury

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We’re often asked to deal with grout used at the floor edge instead of sealant and tiled floors with no room to move, across concrete floor joints, commercial floors and wet room & bathroom floors.

In a village or hamlet like Dunsbury, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

Every job comes with a one-year guarantee, wherever you are in the Isle of Wight.

What happens if it’s left?

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job in most rooms. Around Dunsbury, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Ask before painting over a sealed joint
  • Cone off fresh joints until they’re ready
  • Keep floor cleaning water to a minimum at the edges
  • Look at floor joints each spring

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.

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.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

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

What floor joint sealing looks like in Dunsbury

Across the Isle of Wight, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

In and around Dunsbury, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint. If you look after a church, hall or community building such as St. Mary's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

When it is not the sealant

In fairness, some problems need a different trade:

  • Leaks from a failed tanking system

What affects the cost of floor joint sealing

For a quick quote, just ask. The main things that affect it are:

  • Any working-time requirements on site
  • The type of sealant required
  • How many rooms, windows or areas are involved
  • The size of the job

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • The type of property
  • How we’d reach the joints
  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and give you a clear price.

What happens on the day

When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for most rooms, longer for large commercial floors. In a small place like Dunsbury, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
