About our new build mastic in Southover

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 reaches anything behind it. We work on bathrooms & en suites, windows & doors and kitchens, and common reasons people get in touch are sealant work across a run of new homes and beads laid onto grit and dust from the build.

In smaller places like Southover, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.

A 12-month guarantee comes as standard, so you are covered after we have gone.

What the job involves on each surface

Skirting and floors

Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.

Kitchens

Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.

Leave it or put it right?

DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In an older home around Southover, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Why us?

  • One-year guarantee on every job
  • 4.9 on Google from 180+ five-star reviews
  • Experience in homes, commercial sites and hotels
  • Colour picked to suit the job

Do you need new build mastic in Southover?

Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.

The problems people generally mention when they call include:

  • Cracks appearing as a new home settles
  • Kitchen sealant that has pulled off the wall
  • Sealant that never bonded to the surface
  • Untidy sealant flagged on a snagging list

Around Southover, as everywhere, new build mastic is only as good as the preparation behind it.

What your quote should include

  • Whether they seal over old material or remove it
  • Which colour the sealant will be
  • What insurance they hold
  • How long the guarantee is

10 questions to ask before you book

How it works

We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. For a job in Southover, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive

How to look after the new joints

So the new joints stay in good condition:

  • Look at the sealant regularly in the first couple of years
  • Don’t wait for the house to settle if water is getting through
  • Open a window or run the fan after bathing
  • Raise failed sealant with the developer while you are covered

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
