New build mastic in Sandhurst Cross, done properly

Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include cracks appearing as a new home settles and skirting joints opening in the first winter, across show homes, skirting & floors and windows & doors.

In a village or hamlet like Sandhurst Cross, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

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

What affects the cost of new build mastic

The quote reflects the job in front of us. We look at:

  • Whether old sealant or filler has to be cut out
  • How many rooms, windows or areas are involved
  • Whether the work is at height
  • The size of the job

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 send us an email for an honest opinion and a quote.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Roughly how big the job is
  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • What the problem is, such as mould, gaps, leaks or cracking

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.

What the job involves on each surface

Plot handovers

Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.

Kitchens

As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.

When something else is needed

In fairness, there are a few things sealant won’t fix:

  • Disputes or warranty claims with your builder
  • Settlement cracks that need a surveyor
  • Broken tiles or a split tray

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Surfaces we seal

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

Should I try it myself first?

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.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Do I need to be at home?

Common problems we fix in Sandhurst Cross

Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.

Most people get in touch when they notice something like this:

  • Frame joints opening as the plaster dries
  • Plot mastic for developers ahead of handover
  • Gaps behind new kitchen upstands
  • Gaps opening as the house dries out and settles

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