New build mastic in Hambrook, done properly

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. Typical jobs include cracked caulk along new skirting and smeared, uneven beads picked up at snagging, on bathrooms & en suites, windows & doors and kitchens.

Older homes in small places like Hambrook often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Each job carries a 12-month guarantee.

New build mastic around Hambrook

Hambrook is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

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

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Hambrook, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out.
  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

  • Try not to wet indoor joints just before the visit
  • Tell us if parking is tricky
  • Keep children and pets away from the work area

Keeping the joints in good condition

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

  • Resist patching a failed seal with a tube from the DIY shop
  • Put sealant faults on your snagging list early
  • Watch for new gaps as the house dries out
  • Avoid scourers and strong chemicals on sealant

Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Common problems we fix in Hambrook

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.

People normally contact us when they notice one of these:

  • Untidy sealant flagged on a snagging list
  • Kitchen sealant that has pulled off the wall
  • Sealant applied over dusty or wet surfaces
  • New-build shower sealant that has already split

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

How to choose a mastic man

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How the job changes by surface

Plot handovers

Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.

Windows and doors

Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
