New build mastic in Hartlip

Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on bathrooms & en suites, windows & doors and kitchens, and common reasons people get in touch are second-fix sealing on new plots and kitchen sealant that has pulled off the wall.

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

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Common problems we fix in Hartlip

Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.

Keep an eye out for these signs:

  • Leaking shower tray seals in a new home
  • Internal frame sealant that has split
  • Joints pulling apart as timber shrinks
  • Second-fix sealing on new plots

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

Questions to ask before you book

  • Are they insured?
  • The length of the guarantee
  • What happens if they find a problem under the old sealant
  • Is VAT in the price?

How to choose a mastic man

Different surfaces, different methods

Skirting and floors

New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.

Show homes

Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.

How it works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. In a small place like Hartlip, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  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.

Before we arrive

  • Let us know about earlier repairs to the joints
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
