DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

New build mastic in Sutton Common

Across Sutton Common, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you are dealing with sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home, we can help.

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, in Sutton Common as anywhere.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What we are called out for in Sutton Common

Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.

The most common problems we see are:

  • Sealant applied over dusty or wet surfaces
  • Kitchen sealant that has pulled off the wall
  • Cracks appearing as a new home settles
  • Untidy sealant flagged on a snagging list

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

Before booking anyone

  • Whether you can choose the colour
  • What happens if the job turns out different
  • How the surfaces are prepared before sealing
  • The length of the guarantee

Our hiring checklist

What happens on the day

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. In Sutton Common, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Mention any sign-in or site rules at work premises
  • Clear the area around the work

What affects the quote in Sutton Common

We quote each job individually. These are the things that affect it:

  • The number of rooms or windows
  • The number and length of the joints
  • The old material and how stubborn it is
  • How easy the joints are to reach

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved
  • The address or postcode of the job
  • If someone has resealed it before

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or drop us an email.

How the job changes by surface

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.

Show homes

In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.

New build mastic in Sutton Common: local notes

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

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