About our floor joint sealing in Walmer

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. We work on thresholds, skirting boards and wet room & bathroom floors, and common reasons people get in touch are skirting that has pulled away from the floor and dirt and water collecting in open floor joints.

For a new home in or near Walmer, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Walmer

Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.

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

  • Skirting caulk that keeps splitting
  • Gaps at thresholds between rooms
  • Perimeter joints in tiled floors filled with grout
  • Chipped and open joints in warehouse floors

If you look after a building such as The Downs Church of England Primary School, entrance and corridor floor joints take a lot of traffic.

Choosing a sealant specialist

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

What we cannot put right

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Subfloor problems that need a flooring contractor
  • Failed waterproofing under a wet room floor
  • Loose, hollow or cracked tiles, which need a tiler

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

Where we work in Walmer

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

What happens if it’s left?

Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant stretches instead and keeps the joint sealed. In an older home around Walmer, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Quotes for floor joint sealing in Walmer

There’s no set price list. What we look at:

  • Access and height
  • The number and length of the joints
  • When we can work, for business premises
  • Which sealant suits the joint

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

When you call or email, it’s useful to know:

  • A few photos by email, if you can
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.

Aftercare tips

Aftercare is simple:

  • Do not paint over silicone
  • Check skirting joints after the heating season
  • Get cracks along tile grout lines looked at early
  • Keep dirt out of the joints

Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead.

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

How it works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours, depending on the length of joint. A visit to Walmer is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  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. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
