Honest limits

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Plumbing faults behind the sealant
  • Broken tiles or a split tray
  • Your warranty claim itself, which is between you and the builder

If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

What we seal

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

How we handle new build mastic in Little Hallingbury

Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on bathrooms & en suites, skirting & floors and windows & doors, and common reasons people get in touch are sealant work across a run of new homes and messy sealant that spoils new finishes.

Work in a small place like Little Hallingbury just needs the journey and access planning, and the work itself is the same as on any site.

There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. Somewhere as small as Little Hallingbury, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. We check every joint and tell you how long each needs to cure.

Before we arrive

  • Mention any parking rules near the property
  • Clear the area around the work
  • Keep pets and children clear of the area while we work

Signs you need new build mastic in Little Hallingbury

Baths and trays settle under load once the home is lived in. 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.

If you can see any of these, it’s time to have the joints looked at:

  • Kitchen sealant that has pulled off the wall
  • Internal frame sealant that has split
  • Shower seals failing in the first year or two
  • Gaps between new skirting and floors

For new homes near Sawbridgeworth station, it’s worth checking the sealant early, while snags are still fresh.

When is the best time to reseal in a new build?

That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.

Leave it or put it right?

Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you are unsure which you have, ring 0345 464 0079 or drop us an email with pictures and we will give you a straight answer. Older cottages and farmhouses around Little Hallingbury can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
