About our floor joint sealing in Broad Green

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We are often asked to deal with skirting that has pulled away from the floor and gaps at thresholds between rooms, on tiled floors, skirting boards and concrete floor joints.

London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Broad Green as anywhere.

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

When it is not the sealant

To be straight with you, some problems need a different trade:

  • Cracked or broken concrete slabs
  • Subfloor problems that need a flooring contractor
  • A tiled floor that needs relaying

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

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

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Ask before painting over a sealed joint
  • Cone off fresh joints until they’re ready
  • Don’t slide heavy items over sealed joints
  • Vacuum floor joints regularly to stop grit building up

Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.

Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges and the floor safer.

Signs you need floor joint sealing in Broad Green

An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and behind skirting and plinths.

Look out for any of the following:

  • Dirt and water collecting in open floor joints
  • Gaps at thresholds between rooms
  • Open gaps along the bottom of skirting boards
  • Open joints around bathroom floor edges

For buildings such as Church of St Saviour, floor and skirting joints in halls and kitchens wear like any others.

10 questions to ask before booking

Surface by surface

Concrete floor joints

Old filler, dust and debris are cleaned out of the joint. Backing goes in where the depth needs controlling.

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.

Should I try it myself first?

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.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What happens if it’s left?

Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Broad Green, the repair is bigger than the sealant job would have been.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

FAQs for Broad Green

Do you work for landlords with property near West Croydon station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What should I tell you?

A short description and the location, plus pictures if you have them. We will ask anything else we need to know.

Do you seal kitchen plinths to the floor?

Yes. We cut out any old sealant or caulk and reseal with flexible silicone.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Do I need to be at home?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you seal over the old sealant?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

The process

There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on the length of joint. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Broad Green. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
