Need floor joint sealing in Little Marlow?

Different surfaces, different methods

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges and stops debris collecting.

Floor joint sealing in Little Marlow

Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is generally the better choice because it handles water. Typical jobs include concrete floor joints that have broken down and floor edges that trap water and grime, across concrete floor joints, tiled floors and thresholds.

Somewhere as small as Little Marlow, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Your job is guaranteed for a year, as with all our work.

What sealant work can’t fix

We will not take on work that won’t last, so here’s what sealant can’t put right:

  • Concrete repairs beyond the joint
  • Water getting under the tiles from elsewhere
  • Large cracks that need a surveyor

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

Where we work in Little Marlow

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

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What floor joint sealing looks like in Little Marlow

Across Buckinghamshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

For landlords with property near Bourne End station, gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like Little Marlow CofE School? Then entrance and corridor floor joints take a lot of traffic.

Little Marlow questions

Do you work for landlords with property near Bourne End station?

Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.

Is Little Marlow in your area for floor joint sealing?

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

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Will there be a smell?

Some sealants have a smell while they cure. Opening a window helps.

Can I add another job to the visit?

Yes. More than one area can be quoted together.

Can you match the sealant colour?

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

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

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. Removing the old sealant completely is the only lasting way.

Common problems we fix in Little Marlow

When a tiled floor has no movement joints, the grout takes the strain. You’ll see a crack running along the grout, where a flexible joint should have been.

If you can see any of these, it’s time to have the joints looked at:

  • Floor edges that trap water and grime
  • Cracked grout where a tiled floor needs a movement joint
  • Concrete floor joints that have broken down
  • Open gaps along the bottom of skirting boards

For buildings such as Church of St John the Baptist, joints in its floors, skirtings and thresholds need resealing as they wear.

Questions to ask before you book

  • Whether you can choose the colour
  • What the cure time is
  • How much experience the applicator has
  • Whether VAT is included

Aftercare tips

So the new joints stay in good condition:

  • Look at floor joints each spring
  • Don’t slide heavy items over sealed joints
  • Sweep along the edges of the floor
  • Avoid sloshing water against skirting

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

Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further.

What affects the cost of floor joint sealing

Call for a quick quote. What matters most is:

  • Any mould that needs treating
  • How many areas need sealing
  • How easy the joints are to reach
  • The product the joint needs

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

What to tell us for a quote

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

  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • What’s wrong with the joints now

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work before giving you a price.

How the visit works

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for most rooms, longer for large commercial floors. In a small place like Little Marlow, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • On commercial sites, let us know about site rules
  • Let us know if you’ve seen damp or leaks
