Floor joint sealing in Forty Green

Floor joint sealing in Forty Green

We seal floor joints in homes, offices and commercial buildings across Forty Green. We start by checking the floor type and the joint, because the right sealant depends on both. Typical jobs include skirting caulk that keeps splitting and gaps between floors and kitchen plinths, across thresholds, wet room & bathroom floors and skirting boards.

Older homes in small places like Forty Green often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

A one-year guarantee comes as standard, so you are covered after we have gone.

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Leave it or put it right?

Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Around Forty Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Why Forty Green clients choose us

  • Old sealant always removed completely
  • Rated 4.9 stars on Google
  • A 12-month guarantee on all work
  • Colour picked to suit the job

Common questions in Forty Green

Do you cover Forty Green for floor joint sealing?

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

Do you cover smaller places like Forty Green?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can grout be replaced with sealant on a tiled floor?

Often, yes. A crack along a grout line often means the floor needs room to move. We rake out that line and seal it with flexible sealant.

Is there a guarantee?

Yes, always. Each job is guaranteed for twelve months.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.

Where are you based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

When it is not the sealant

A few problems are outside what sealant work can do:

  • Concrete repairs beyond the joint
  • A tiled floor that needs relaying
  • Leaks from a failed tanking system

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

The process

You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on the length of joint for a typical job. Somewhere as small as Forty Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
