About our new build mastic in Leigh Park

Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for worktop and upstand sealant coming away and frame joints opening as the plaster dries, on show homes, kitchens and windows & doors.

If you’ve bought a new home in or near Leigh Park, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

We stand behind the work with a one-year guarantee.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

New homes and floors in Leigh Park

Leigh Park is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

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

DIY versus a professional finish

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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. In a smaller place like Leigh Park, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  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. Each bead is tooled and the cure times explained.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises

Aftercare tips

A little care helps the new joints last. We recommend:

  • Report sealant problems to your builder during the snagging period
  • Do not wait for the house to settle if water is getting through
  • Use the extractor fan every time you shower
  • Wait for the cure time before using a resealed shower

Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

Common problems we fix in Leigh Park

Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.

People normally contact us after spotting something like this:

  • Worktop and upstand sealant coming away
  • Cracked caulk along new skirting
  • Untidy sealant flagged on a snagging list
  • Sealant applied over dusty or wet surfaces

In and around Leigh Park, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Before booking anyone

  • How long the guarantee is
  • When the joint can take water or movement
  • Is the old sealant removed completely?
  • What insurance they hold
