Floor joint sealing in Stonor, done properly

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out. If you are dealing with open joints around bathroom floor edges and grout cracking in a straight line across a floor, we can help, whatever the surface.

For a small place like Stonor, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

There’s a 12-month guarantee on every job, large or small.

What we do, step by step

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Stonor, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the floor type, the gap and the traffic are checked.
  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.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints
  • Mention any tricky access

Work for landlords, hotels and businesses

Landlords and letting agents in Stonor can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Mark off resealed joints in warehouses
  • Do not paint over silicone
  • Don’t fill floor joints with caulk where they move or get wet
  • Keep floor cleaning water to a minimum at the edges

Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.

FAQs for Stonor

Do you cover Stonor for floor joint sealing?

Yes. Our work covers London and the South East, and Stonor is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.

Is floor joint sealing in Stonor guaranteed?

All our work, in Stonor and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Where do you work from?

We work from Crawley. We cover Stonor and the rest of Oxfordshire, along with the rest of our area.

Why does the gap under my skirting keep coming back?

Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.

Can I choose the sealant colour?

Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Do you need floor joint sealing in Stonor?

A floor laid tight to the walls has no room to move. As it expands, the edges lift or crack, and the sealant or grout breaks.

Most people get in touch when they notice something like this:

  • Cracked caulk along skirting in bathrooms and kitchens
  • Skirting that has pulled away from the floor
  • Dirt and water collecting in open floor joints
  • Perimeter joints in tiled floors filled with grout

Community buildings like Pishill Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Are they insured?
  • Is the old sealant removed completely?
  • Which sealant they’ll use, and why

Our hiring checklist

What happens if it’s left?

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Older cottages and farmhouses around Stonor can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

What we can’t put right

In fairness, there are a few things sealant won’t fix:

  • Bouncy or failing floorboards
  • Leaks from a failed tanking system
  • Large cracks that need a surveyor

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Where we work in Stonor

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

Different surfaces, different methods

Thresholds

Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.

Tiled floors

A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it if it’s in the right place.
