New build mastic in Little Venice

How we handle new build mastic in Little Venice

In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. Common call-outs are for gaps between new skirting and floors and cracks appearing as a new home settles, across show homes, plot handovers and kitchens.

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, in Little Venice as anywhere.

Our work is backed for twelve months, in Little Venice and everywhere else we cover.

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.

Windows and doors

Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

Looking after it afterwards

So the new joints stay in good condition:

  • Raise failed sealant with the developer while you are covered
  • Follow the cure time we give you
  • Avoid running a DIY bead over the old one
  • Don’t wait for the house to settle if water is getting through

Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the number of plots. For a job in Little Venice, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  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. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Mention if the joints have been sealed before
  • Tell us about any water getting in
  • On commercial sites, let us know about site rules

What affects the quote in Little Venice

We quote each job individually. This is what makes a difference:

  • Whether the work is at height
  • Which sealant suits the joint
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove

The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

Asking for a quote

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

  • Any previous sealing or DIY work
  • Roughly how big the job is
  • Where the job is, and your postcode
  • The type of property

For new build mastic in Little Venice, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

New homes and floors in Little Venice

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

As a London address, Little Venice can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near London Paddington station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?

It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Little Venice.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Why us?

  • Colour picked to suit the job
  • Approved under the ARBOMaster scheme
  • Anti-fungal sanitary silicone in wet areas

Common questions in Little Venice

Can you help a landlord with a rental near London Paddington station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

Can parking be tricky for a visit in Little Venice?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Can I add another job to the visit?

Yes. Several rooms, windows or areas can go on one quote.

Is it normal for sealant to crack in a new home?

It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

What colour sealant will you use?

That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.

Do you come to Little Venice?

Yes. We work in Little Venice, as part of our work across South East England, London and Scotland. To book, ring 0345 464 0079 or send us an email.

How long before the joint can be used?

Different products cure at different speeds, so follow the cure time we give you.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few pictures.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Structural cracks in walls or ceilings
  • Broken tiles or a split tray
  • Leaking fittings rather than failed sealant

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