Need new build mastic in Cove?

DIY sealant or a professional job?

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.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

About our new build mastic in Cove

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on plot handovers, windows & doors and skirting & floors, and people most often call us about new-build shower sealant that has already split and messy sealant that spoils new finishes.

In and around Cove, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.

We stand behind the work with a 12-month guarantee.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Wipe joints with warm soapy water
  • Photograph failed sealant before it’s redone
  • Open a window or run the fan after bathing
  • Wait for the cure time before using a resealed shower

Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.

The process

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. A visit to Cove is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Each joint is checked for movement before work begins.
  2. We remove the failed sealant and clean the joints.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Let us know about stairs, lifts or work at height
  • Mention any leaks or damp you’ve noticed

Advice

Different surfaces, different methods

Kitchens

As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.

Windows and doors

The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.

What we’re called out for in Cove

Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.

Signs it’s time to call us include:

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

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

What to look for in a quote

  • What product goes in the joint
  • How the joint is cleaned and prepared
  • How long to leave it before use
  • Are they insured?

Our hiring checklist

When it isn’t the sealant

We won’t take on work that won’t last, so these are the limits:

  • Leaks from pipes, valves or wastes, which need a plumber
  • Settlement cracks that need a surveyor
  • A tray or bath that isn’t properly supported, until it’s fixed

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
