  • How many rooms, windows or areas are involved
  • Access and height
  • How much old sealant there is and how hard it is to remove

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • The rough size of the job
  • If it’s domestic, commercial or a hotel

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

How we handle floor joint sealing in New Street

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. We work on concrete floor joints, tiled floors and commercial floors, and common reasons people get in touch are worn sealant at door thresholds and failed seals where bathroom floors meet baths and panels.

Around New Street, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Common questions in New Street

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

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you cover smaller places like New Street?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Can you match the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.

How long does floor joint sealing take?

Typically it takes a few hours, depending on the length of joint. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Why does the gap under my skirting keep coming back?

It’s normally the floor moving: heating drying the timber, or a filler that’s too rigid. A flexible bead keeps up with the movement.

What happens if it’s left?

Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead, so the joint stays closed. Where a wall is exposed, as many are in small places like New Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Floor joint sealing around New Street

Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

Schools such as Culverstone Green Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic. For landlords with property near Meopham station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as Church of Saint Peter, floor and skirting joints in halls and kitchens wear like any others.

When it isn’t the sealant

It helps to know what we cannot do too:

  • Loose, hollow or cracked tiles, which need a tiler
  • Cracked or broken concrete slabs
  • Floors that are uneven or need levelling

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Surface by surface

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk.

Thresholds

Where a tiled floor meets timber or carpet, the joint takes movement from both sides. We bridge them with a flexible bead.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most rooms, longer for large commercial floors and we leave things clean and tidy. Somewhere like New Street needs a little journey planning: 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. Old caulk, grout or sealant is removed from the joint.
  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. Finally we tool it smooth and explain when the floor can be used and cleaned.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work
  • Let us know about parking restrictions
