The process

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for most rooms, longer for large commercial floors, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • Tell us if parking is tricky

Floor joint sealing in Belvedere, done properly

Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. We work on skirting boards, tiled floors and wet room & bathroom floors, and people most often call us about skirting that has pulled away from the floor and threshold joints that have opened or worn.

New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

All our work comes with our one-year guarantee, wherever you are in Greater London.

How we quote for floor joint sealing

There’s no set price list, because jobs vary so much. The quote depends on:

  • Any mould that needs treating
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove
  • How many areas need sealing

Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.

What to tell us for a quote

When you contact us, it’s useful to know:

  • If it’s domestic, commercial or a hotel
  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before
  • Pictures of the joints, sent by email

Every job is quoted individually. Just call 0345 464 0079 or send us an email with the details.

What we can’t put right

It helps to know what we can’t do:

  • Concrete repairs beyond the joint
  • A tiled floor that needs relaying
  • Large cracks that need a surveyor

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.

What we seal

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

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. 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.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

When to call us in Belvedere

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands, and the sealant or grout breaks.

If you can see any of these, it’s time to have the joints looked at:

  • Failed seals where bathroom floors meet baths and panels
  • Concrete floor joints that have broken down
  • Open gaps along the bottom of skirting boards
  • Open joints that fill with dirt

Rented homes near Belvedere station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

Questions to ask before you book

  • How long to leave it before use
  • How hidden problems are handled
  • What guarantee comes with the work
  • Are they insured?

Choosing a sealant specialist

What the job involves on each surface

Tiled floors

Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines.

Skirting boards

Skirting-to-floor joints are a regular job for us. The old caulk is removed first.

Landlord and commercial work in Belvedere

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Belvedere: your questions answered

Can you do floor joint sealing in Belvedere?

Yes. Our work covers London and the South East, and Belvedere is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.

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

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

Can grout be replaced with sealant on a tiled floor?

Generally, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.

Do you offer different sealant colours?

In most cases you can choose. We will tell you which colours the right product comes in.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors. Caulk tends to crack; a flexible sealant doesn’t.

What should I tell you?

Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned.

Joints and finishes in Belvedere homes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.

Schools such as Lessness Heath Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic. For buildings such as Parish Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear.
