New homes and floors in Strand-on-the-Green

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. That’s why the skirting and threshold joints need a flexible seal.

As a London address, Strand-on-the-Green can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Chiswick station, gaps at skirtings and thresholds are worth sealing between tenancies.

Floor joint sealing for homes and businesses in Strand-on-the-Green

Tiled floors can crack along the grout when there’s no room for movement. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. If you have concrete floor joints that have broken down and cracked grout where a tiled floor needs a movement joint, we can help.

New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

A one-year guarantee comes as standard.

Honest limits

A few problems are outside what sealant work can do:

  • Cracked or broken concrete slabs
  • Water getting under the tiles from elsewhere
  • Floors that are uneven or need levelling

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

Where we work in Strand-on-the-Green

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

Why deal with it now?

Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In a flat in Strand-on-the-Green, 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.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

How we quote for floor joint sealing

The price is agreed before any work begins. It takes into account:

  • The type of sealant required
  • Mould in or behind the old joints
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Whether it has been sealed before
  • Whether it’s a home or a business
  • The address or postcode of the job
  • How we’d reach the joints

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

Do you need floor joint sealing in Strand-on-the-Green?

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting, then close again in damper months.

The problems people generally mention when they call include:

  • Worn sealant at door thresholds
  • Failed seals where bathroom floors meet baths and panels
  • Concrete floor joints that have broken down
  • Cracked grout where a tiled floor needs a movement joint

For buildings such as St Paul's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Whether all the old sealant comes out first
  • Is VAT in the price?
  • When the joint can take water or movement

10 questions to ask before you book

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

How the job changes by 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

A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it if it’s in the right place.

What we do, step by step

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most rooms, longer for large commercial floors. In a London area like Strand-on-the-Green, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about parking restrictions
