DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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 does not work out, we can still put it right.

How we handle new build mastic in West Ealing

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you have leaking shower tray seals in a new home and plot mastic for developers ahead of handover, we can help.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

Big or small, it’s backed by our one-year guarantee.

Your questions about new build mastic in West Ealing

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

Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.

Is parking a problem for a job in West Ealing?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Will there be a smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

Should I try DIY first?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do you work in West Ealing?

Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes West Ealing.

Is the work guaranteed?

Yes. Every job comes with a one-year guarantee.

Should I wait before resealing?

Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.

Why has my new-build shower seal failed already?

There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

Why it’s worth doing now in West Ealing

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in West Ealing, the repair is bigger than the sealant job would have been.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

How it works

We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes a few hours for most snagging lists, longer for a run of plots. In a London area like West Ealing, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely, with no layer left behind.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Keep children and pets away from the work area
  • Mention any parking rules near the property
  • Let us know about earlier repairs to the joints

New homes and floors in West Ealing

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

As a London address, West Ealing can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Do you need new build mastic in West Ealing?

Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.

It’s worth asking for a quote if you see:

  • New-build shower sealant that has already split
  • Cracks appearing as a new home settles
  • Sealant applied over dusty or wet surfaces
  • Skirting joints opening in the first winter

If you’ve bought a new home near Hanwell station, the sealant around baths, showers and frames is worth checking in the first year or two.

What your quote should include

  • The length of the guarantee
  • How the joint is cleaned and prepared
  • What happens if they find a problem under the old sealant
  • How long to leave it before use
