Floor joint sealing for West Hampstead homes and businesses

Floor joint sealing in West Hampstead

Across West Hampstead, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, because the right sealant depends on both. Typical jobs include tiled floors with no room to move and threshold joints that have opened or worn, on tiled floors, commercial floors and concrete floor joints.

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.

All our work is covered by our 12-month guarantee, wherever you are in Greater London.

DIY sealant or a professional job?

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 doesn’t work out, we can still put it right.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

When it is not the sealant

Before booking, it’s worth knowing the limits:

  • Water getting under the tiles from elsewhere
  • Floors that are uneven or need levelling
  • Structural movement or subsidence

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

Where we work in West Hampstead

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

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Use furniture pads near skirting
  • Have a cracking tiled floor checked before tiles break
  • Ask before painting over a sealed joint
  • Avoid sloshing water against skirting

Avoid flooding the floor when you clean. Less water at the edges helps the joints last.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

How we quote for floor joint sealing

Jobs vary more than people expect. The main factors:

  • The type of sealant required
  • Whether the work is at height
  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Helping us quote

Before you ask for a quote, have a think about:

  • A few pictures by email, if you can
  • How we’d reach the joints
  • Where the property is
  • If it’s domestic, commercial or a hotel

For floor joint sealing in West Hampstead, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before any work starts.

How the visit works

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on the length of joint in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in West Hampstead. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions

Advice

Work for landlords, hotels and businesses

Landlords and agents in West Hampstead can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Why it’s worth doing now in West Hampstead

The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. In a flat in West Hampstead, 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.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Why us?

  • Fully insured
  • We leave the area clean and tidy
  • We agree the colour with you first
  • Anti-fungal sanitary silicone in wet areas

Do you work for landlords with property near Finchley Road & Frognal station?

Do you seal warehouse floor joints?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we’ll quote.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Can you seal where the floor meets the bath panel?

Yes. These joints get wet every time the floor is cleaned, so a flexible silicone is the right choice.

Do you offer different sealant colours?

Most of the time, yes. We’ll tell you which colours the right product comes in.

Can sealant along the skirting be painted?

Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted, so tell us your plans.

Floor joint sealing in West Hampstead: local notes

Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

As a London address, West Hampstead can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Finchley Road & Frognal station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as Presbyterian Church Of St Andrew, joints in its floors, skirtings and thresholds need resealing as they wear.
