Surface by surface

Concrete floor joints

Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.

Wet room and bathroom floors

Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone that keeps water out.

About our floor joint sealing in Arnos Grove

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. We work on skirting boards, thresholds and tiled floors, and the jobs we see most are chipped and open joints in warehouse floors and open joints that fill with dirt.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.

All of our work is guaranteed for twelve months, in Arnos Grove and everywhere else we cover.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Mark off resealed joints in warehouses
  • Avoid sloshing water against skirting
  • Keep dirt out of the joints
  • Use furniture pads near skirting

Check the joints after the first winter. Small gaps at the ends can be touched up before they spread.

A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.

Work for landlords, hotels and businesses

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.

What happens on the day

You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on the length of joint for a typical job. In Arnos Grove, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. Finally, we check the work and talk you through aftercare.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

New homes and floors in Arnos Grove

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, 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.

Rented homes near New Southgate station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Bowes Primary School, entrance and corridor floor joints take a lot of traffic. As a London address, Arnos Grove can be tricky for parking: let us know about parking bays, permits or a driveway.

FAQs for Arnos Grove

Can grout be replaced with sealant on a tiled floor?

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant so the floor can move.

Are you fully insured?

Yes. We’re fully insured.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Do you seal floor joints in bathrooms and kitchens?

Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

What we cannot put right

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Concrete repairs beyond the joint
  • Floors that are uneven or need levelling
  • Loose, hollow or cracked tiles, which need a tiler

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

Surfaces we seal

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

Why it’s worth doing now in Arnos Grove

Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Some things make a job bigger or smaller: 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.

Why us?

  • We are fully insured
  • Experience in homes, commercial sites and hotels
  • White, clear, grey or another colour, product permitting
  • More than 20 years in sealant work

Should I try it myself first?

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

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
