Floor joint sealing near Catford

Should I try it myself first?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How we handle floor joint sealing in Catford

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. We are often asked to deal with gaps at thresholds between rooms and cracked caulk along skirting in bathrooms and kitchens, across skirting boards, commercial floors and tiled floors.

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.

When it is not the sealant

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Concrete repairs beyond the joint
  • Leaks from a failed tanking system
  • Loose, hollow or cracked tiles, which need a tiler

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

Surfaces we seal

Work for landlords, hotels and businesses

How we quote for floor joint sealing

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The number of rooms or windows
  • The product the joint needs
  • The amount of work
  • Access and height

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

To help us quote quickly, please include:

  • The address or postcode of the job
  • Roughly how big the job is
  • Photos by email, if that’s easy
  • The problem you’ve noticed

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.

Why it’s worth doing now in Catford

Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. In a flat in Catford, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Why book with us

  • An ARBOMaster approved applicator
  • Experience in homes, commercial sites and hotels
  • Quality sealants from Arbo and Everbuild
  • Neat joints and a tidy finish

New homes and floors in Catford

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. That’s why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.

For site and facilities teams at buildings such as Holy Cross Catholic Primary School, entrance and corridor floor joints take a lot of traffic. Community buildings like Church of St Laurence and Community Centre are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Catford is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Your questions about floor joint sealing in Catford

Do you cover Catford for floor joint sealing?

Yes, Catford is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.

Is parking a problem for a job in Catford?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Can you seal where the floor meets the bath panel?

Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone to keep mop water out.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Can I add another job to the visit?

Yes. Just list everything you need and you’ll get one quote.

Do you use a paintable sealant?

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

Size, access and the old material all affect the cost. Call for a quick quote.

What the job involves on each surface

Concrete floor joints

Hard wheels break down the edges of open joints. Sealing them supports the edges.

Commercial floors

In commercial buildings, we can plan floor joint work around opening hours. Out-of-hours working can be arranged.

How the visit works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on the length of joint. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  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. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
