About our floor joint sealing in Tooting

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 concrete floor joints, commercial floors and thresholds, and people most often call us about floor edges that trap water and grime and gaps between floors and kitchen plinths.

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 Tooting as anywhere.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Landlords, agents and businesses in Tooting

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

How it works

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours, depending on the length of joint. In Tooting, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  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. We apply a flexible sealant suited to the floor.
  5. Finally, we check the work and talk you through aftercare.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work

Advice

Tooting: your questions answered

Is parking an issue for floor joint sealing in Tooting?

Parking in Tooting, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Do you work for landlords with property near Tooting station?

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

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can you add a movement joint to a tiled floor?

Often, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Is caulk good enough for skirting?

Caulk can’t cope with movement or water. Floor edges move through the year, so a flexible sealant suits them better.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Do you guarantee your work?

Yes. All our work carries our 12-month guarantee.

How to look after the new joints

Aftercare is simple:

  • Look at floor joints each spring
  • Keep heavy wheels off new concrete joints until cured
  • Avoid sloshing water against skirting
  • Keep caulk for dry, still joints only

Follow the cure time before walking on or cleaning the joint. Light foot traffic is normally fine sooner than wet cleaning or wheels.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

When to call us in Tooting

Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open.

People normally contact us when they notice one of these:

  • Chipped and open joints in warehouse floors
  • Threshold joints that have opened or worn
  • Tiled floors with no room to move
  • Skirting that has pulled away from the floor

Managing a site like St Boniface RC Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What your quote should include

  • What product goes in the joint
  • Whether you can choose the colour
  • How long to leave it before use
  • Who turns up on the day

Quotes for floor joint sealing in Tooting

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • Which sealant suits the joint
  • Any working-time requirements on site
  • The number and length of the joints
  • How easy the joints are to reach

Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we need to know

To make quoting easier, please include:

  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • Whether it’s a home or a business
  • Photos by email, if that is easy

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or email us.

When it is not the sealant

It helps to know what we can’t do too:

  • Subfloor problems that need a flooring contractor
  • Water getting under the tiles from elsewhere
  • Damaged concrete that needs breaking out and repairing

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

Surfaces we seal

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

Floor joint sealing around Tooting

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.

For buildings such as St Augustine, floor and skirting joints in halls and kitchens wear like any others. Letting a property close to Tooting station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

Why it’s worth doing now in Tooting

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor and keeps the joint sealed. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Tooting.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why us?

  • We leave the area clean and tidy
  • Any old sealant cut out fully, not covered over
  • Full insurance on every job
  • Approved under the ARBOMaster scheme
