How the visit works

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours, depending on the length of joint, depending on the amount of work. For a village or hamlet like Newton Valence, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. We take out any old caulk, sealant or grout along the line.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • Mention any parking rules near the property
  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we’re working on

Newton Valence: your questions answered

Is Newton Valence in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Newton Valence is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.

I let a flat near Alton station. Can you help?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.

Do you have insurance?

Yes. Full insurance covers our work.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Can I choose the sealant colour?

We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

What causes gaps between the floor and skirting?

Normally it’s movement: heating drying the timber, or a filler that is too rigid. A flexible sealant stays closed as the floor moves.

When can I walk on the floor?

It depends on the product and the conditions. We give you the times for walking, cleaning and traffic when we finish so you can plan.

Will I be able to paint over the new joint?

Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone is not made to be painted, so it’s kept for wet areas and unpainted joints.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.

What we’re called out for in Newton Valence

A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands and joints fail.

The most common problems we see are:

  • Perimeter joints in tiled floors filled with grout
  • Threshold joints that have opened or worn
  • Floor edges that trap water and grime
  • Caulk that has cracked where the floor moves

Community buildings like Church of St Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • What insurance they hold
  • How the surfaces are prepared before sealing
  • What happens if the job turns out different
  • Whether you can choose the colour

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

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.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Have a cracking tiled floor checked before tiles break
  • Ask before painting over a sealed joint
  • Use a well-wrung mop rather than flooding the floor
  • Keep dirt out of the joints

Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

Why it’s worth doing now in Newton Valence

Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Where a wall is exposed, as many are in small places like Newton Valence, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
