Floor joint sealing near Silvertown

Floor joint sealing in Silvertown

Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, then clean, back and seal the joint. If you have open joints around bathroom floor edges and open gaps along the bottom of skirting boards, we can help.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement.

You get a 12-month guarantee, the same in Silvertown as everywhere else we work.

Why deal with it now?

Floor joints left open collect dirt that is hard to clean out. A neat sealed joint is easier to clean. In a flat in Silvertown, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Why us?

  • ARBOMaster approved applicator
  • Old sealant always removed completely
  • We’re fully insured
  • Domestic, commercial and hotel work

Questions from Silvertown

I let a flat near Custom House station. Can you help?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Can you do floor joint sealing in Silvertown?

Yes. Our work covers London and the South East, and Silvertown is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.

Do you seal kitchen plinths to the floor?

Yes. We cut out any old sealant or caulk and reseal with flexible silicone in a colour to suit.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Will I be able to paint over the new joint?

Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone is not made to be painted, so we use it where the joint stays unpainted.

Can you use decorators’ caulk instead?

Not where the floor moves or gets wet. Caulk cracks as the floor moves and the gap reopens. A flexible sealant is the better choice.

Are you fully insured?

Yes. We are fully insured.

Different surfaces, different methods

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.

Wet room and bathroom floors

Bathroom floor edges get wet at every clean. A flexible seal stops water running into the gap.

Honest limits

We won’t take on work that won’t last, so these are the limits:

  • Bouncy or failing floorboards
  • Failed waterproofing under a wet room floor
  • Movement too big for a sealant joint

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

What we seal

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

What affects the cost of floor joint sealing

We don’t publish a price list, because no two jobs are the same. What we look at:

  • Which sealant suits the joint
  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • How many rooms, windows or areas are involved

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Helping us quote

To help us quote quickly, let us know:

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

To get a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.

What we do, step by step

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a morning or an afternoon for most homes. 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 we check the joint and the floor and agree which sealant suits it.
  2. Old caulk, grout or sealant is removed from the joint.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  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.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Tell us about any previous sealing or DIY attempts
  • Tell us about access, such as stairs, a lift or high-level joints

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or send us an email.

Signs you need floor joint sealing in Silvertown

An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap.

Any of these means the joints need attention:

  • Skirting that has pulled away from the floor
  • Failed joint filler in concrete floors
  • Threshold joints that have opened or worn
  • Dirt and water collecting in open floor joints

If you look after a building such as Britannia Village Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What your quote should include

  • Are they insured?
  • What happens if the job turns out different
  • Who turns up on the day
  • How long to leave it before use

Joints and finishes in Silvertown homes

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.
