Floor joint sealing near Hendon

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Floor joint sealing in Hendon, done properly

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you have worn sealant at door thresholds and dirt and water collecting in open floor joints, we can put it right, whatever the surface.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What floor joint sealing looks like in Hendon

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 each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

Hendon is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as Christ Church Hendon, floor and skirting joints in halls and kitchens wear like any others.

Hendon is about 3 miles north-west of Hampstead, in Greater London. From the centre of Hendon to the outskirts, floor joint sealing is available for homes and businesses alike, from flats and houses to offices and hotels. Hendon is one of 764 towns and villages in Greater London where we work for floor joint sealing. We also work in London, about 8 miles from Hendon.

What affects the cost of floor joint sealing

We quote each job individually. These are the things that affect it:

  • Access and height
  • The number of rooms or windows
  • Which sealant suits the joint
  • How much old sealant there is and how hard it is to remove

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Asking for a quote

What to tell us when you ask for a quote:

  • The address or postcode of the job
  • Whether it’s a home or a business
  • What’s wrong with the joints now
  • How we’d reach the joints

Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Why deal with it now?

Dirt builds up in open joints. Sealed joints are easier to keep clean and finishes the floor. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Hendon, the repair is bigger than a sealant job.

What you pay reflects the work, not guesswork. That is why we ask about the job first.

FAQs for Hendon

Do you work for landlords with property near Hendon station?

Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Can you do floor joint sealing in Hendon?

Yes. We work across London and the South East, and Hendon is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.

Can sealant along the skirting be painted?

It depends on the sealant, so let us know first. Joints that will be painted get a paintable product, and silicone elsewhere.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Is there a guarantee?

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

Are you fully insured?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

How soon can the floor be mopped?

We give you a cure time for each joint. Feet are usually fine first, then mopping, then heavy wheels.

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 so water can’t get into the gap.

What we cannot put right

Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:

  • Bouncy or failing floorboards
  • A tiled floor that needs relaying
  • Failed waterproofing under a wet room floor

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

Joints and surfaces we work on

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

How it works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it 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. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about earlier repairs to the joints
  • Let us know if you’ve seen damp or leaks

How to get a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.

Advice

What we are called out for in Hendon

New floors settle once they’re in use. Gaps at the edges appear in the first year or so and anything rigid cracks.

  • Worn sealant at door thresholds
  • Failed seals where bathroom floors meet baths and panels
  • Open gaps along the bottom of skirting boards
  • Concrete floor joints that have broken down

For landlords with property near Hendon station, gaps at skirtings and thresholds are worth sealing between tenancies.

Our hiring checklist

What the job involves on each surface

Wet room and bathroom floors

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

Tiled floors

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