Floor joint sealing for Oval homes and businesses

Floor joint sealing in Oval, done properly

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant so water and dirt can’t get in. Common call-outs are for cracked caulk along skirting in bathrooms and kitchens and open joints that fill with dirt, on commercial floors, tiled floors and skirting boards.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How it works

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for most rooms, longer for large commercial floors, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Oval. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Before we arrive

  • Let us know about parking restrictions
  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed

Advice

How we quote for floor joint sealing

We don’t publish a price list, because jobs vary so much. What we look at:

  • The number and length of the joints
  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • The type of sealant required

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. We take all of that into account in your quote.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

For floor joint sealing in Oval, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.

Do you need floor joint sealing in Oval?

Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting, then close again in damper months.

Any of these means the joints need attention:

  • Open joints around bathroom floor edges
  • Gaps opening between the floor and skirting
  • Concrete floor joints that have broken down
  • Cracked caulk along skirting in bathrooms and kitchens

Oval is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Before booking anyone

  • What insurance they hold
  • What product goes in the joint
  • How hidden problems are handled
  • Is the old sealant removed completely?

10 questions to ask before booking

Different surfaces, different methods

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk painted or coloured to match.

Thresholds

Thresholds take daily traffic, so the sealant has to be tough as well as flexible and tool it flush.

What floor joint sealing looks like in Oval

Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

For landlords with property near Vauxhall station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Schools such as St Stephen's Church of England Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic.

For landlords and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

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

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Check the sealant is paintable before decorating
  • Mark off resealed joints in warehouses
  • Get cracks along tile grout lines looked at early
  • Avoid caulk in bathrooms and kitchens

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.

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

Common questions in Oval

I let a flat near Vauxhall station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.

Can parking be tricky for a visit in Oval?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Will I be able to paint over the new joint?

On joints you want to paint, yes. Silicone in bathrooms and kitchens cannot be painted so mention it when you get a quote.

What should I tell you?

A short description and the location. If we need more, we will ask.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Do you have insurance?

Yes. We’re fully insured for domestic and commercial work.

Where do you work from?

Our base is Crawley. Our area covers South East England, London and Scotland.

Honest limits

New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:

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

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