Floor joint sealing in Old Tree, done properly

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out and stops dirt collecting. We work on tiled floors, wet room & bathroom floors and thresholds, and people most often call us about cracked caulk along skirting in bathrooms and kitchens and gaps opening between the floor and skirting.

For a small place like Old Tree, the journey and access are planned in advance, and the work itself is the same as on any site.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints

After the cure time, these simple habits help:

  • Walk round the room once a year and look at the edges
  • Cone off fresh joints until they’re ready
  • Use a well-wrung mop rather than flooding the floor
  • Do not paint over silicone

Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.

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

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works.

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for most rooms, longer for large commercial floors. Somewhere like Old Tree needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any leaks or damp you’ve noticed
  • Clear the area around the work

Advice

Signs you need floor joint sealing in Old Tree

A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.

These are the problems we are asked about most:

  • Open joints around bathroom floor edges
  • Grout used at the floor edge instead of sealant
  • Worn sealant at door thresholds
  • Cracked caulk along skirting in bathrooms and kitchens

If you look after a building such as Hoath Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What your quote should include

  • How much experience the applicator has
  • Whether they seal over old material or remove it
  • What insurance they hold
  • What the cure time is

Choosing a sealant specialist

Old Tree: your questions answered

Do you work for landlords with property near Herne Bay station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Is Old Tree in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Old Tree is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Are you fully insured?

Yes. We are fully insured.

Will there be a smell?

It depends on the product. Some smell for a while, some hardly at all.

Do you seal warehouse floor joints?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic and we will quote.

Why not just use caulk?

Caulk works on still, dry joints, but it splits where the joint moves or gets wet. For most floor joints, we use a flexible sealant.

Can I choose the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

Surface by surface

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.

Concrete floor joints

We clean concrete joints out thoroughly before sealing, vacuuming them clean. We fit backing where needed.

Why deal with it now?

Floor joints left open collect dirt that is hard to clean out and makes the floor look worn. Sealed joints are easier to keep clean and finishes the floor. Around Old Tree, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Can I do it myself?

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, and the work is guaranteed for a year.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
