What the job involves on each surface

Skirting boards

Gaps between skirting and floor open as timber and floors move. We seal them with a flexible sealant rather than caulk.

Tiled floors

The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.

Floor joint sealing for homes and businesses in Selsted

The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk generally cracks where there’s movement, so we close it with a flexible sealant instead. We work on tiled floors, concrete floor joints and thresholds, and common reasons people get in touch are worn sealant at door thresholds and failed joint filler in concrete floors.

Older homes in small places like Selsted often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards

After the cure time, these simple habits help:

  • Get cracks along tile grout lines looked at early
  • Mark off resealed joints in warehouses
  • Keep caulk for dry, still joints only
  • Keep dirt out of the joints

Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels.

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

Do you need floor joint sealing in Selsted?

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands and joints fail.

It’s worth asking for a quote if you see:

  • Failed seals where bathroom floors meet baths and panels
  • Caulk that has cracked where the floor moves
  • Rigid edge joints in tiled floors
  • Cracked grout where a tiled floor needs a movement joint

If you let a flat or house near Shepherds Well station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Questions from Selsted

Do you cover Selsted for floor joint sealing?

Yes, Selsted is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.

I let a flat near Shepherds Well station. Can you help?

Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Do you offer different sealant colours?

Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.

Is the work guaranteed?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Which products do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Where do you work from?

We work from Crawley. We cover Selsted and the rest of Kent, along with the rest of our area.

What affects the quote in Selsted

For a quick quote, just ask. What matters most is:

  • The number of rooms or windows
  • How easy the joints are to reach
  • How much there is to do
  • The product the joint needs

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.

  • Whether it has been sealed before

Want a quote for floor joint sealing? Please ring 0345 464 0079 or send us an email and tell us about the job. We will explain what we’d do and send you a clear quote before any work starts.

Can I do it myself?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

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.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Floor joint sealing around Selsted

Across Kent, 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.

If you look after a building such as Selsted Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

How it works

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most rooms, longer for large commercial floors. In a small place like Selsted, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
