About our new build mastic in Plashet

A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have gaps opening as the house dries out and settles and kitchen sealant that has pulled off the wall, we can help, whatever the surface.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement, in Plashet as anywhere.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Plashet questions

Do you work for landlords with property near Woodgrange Park station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Is Plashet in your area for new build mastic?

Yes. We work across London and the South East, and Plashet is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.

Why has my new-build shower seal failed already?

There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

What should I tell you?

Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.

Does someone need to be in?

Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Can you quote for more than one area?

Yes. Just list everything you need and we will quote it together.

Are you insured?

Yes. We are fully insured for domestic and commercial work.

Why deal with it now?

Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a flat in Plashet, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

How the job changes by surface

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.

Bathrooms and en suites

Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.

When something else is needed

It helps to know what we cannot do too:

  • A tray or bath that is not properly supported, until it’s fixed
  • Disputes or warranty claims with your builder
  • Plumbing faults behind the sealant

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

Joints and surfaces we work on

  • Windows & doors
  • Bathrooms & en suites
  • Plot handovers
  • Show homes
  • Skirting & floors
  • Kitchens

What happens on the day

You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours in a single home for a typical job. In Plashet, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  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. 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.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property
  • For business premises, tell us about site rules or sign-in

Advice

New build mastic in Plashet: local notes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

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

What we are called out for in Plashet

Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.

Signs it’s time to call us include:

  • Gaps behind new kitchen upstands
  • New-build shower sealant that has already split
  • Untidy sealant flagged on a snagging list
  • Cracked caulk along new skirting

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

Before booking anyone

  • Whether all the old sealant comes out first
  • Whether you can choose the colour
  • What preparation is included
  • When the joint can take water or movement

Our hiring checklist

Aftercare tips

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep pictures and emails about snagging items
  • Follow the cure time we give you
  • Put sealant faults on your snagging list early
  • Look at the sealant regularly in the first couple of years

Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.

Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

Landlord and commercial work in Plashet

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
