Warm, dry living room in a well insulated Wellington home

Ceiling and roof insulation

Stop the heat escaping through the top.

Heat rises, and in a poorly insulated home it goes straight out through the ceiling and roof. Fresh ceiling insulation keeps that warmth in the rooms where you feel it, and it is one of the best-value upgrades you can make.

Upgrade the top of the house

Old insulation is often barely working.

Insulation settles and flattens over the years, and gaps open up around downlights, hatches and edges. That lets warmth leak away all winter. We assess what is up there, then top it up or replace it so your ceiling does the job it should.

  • Inspection of your existing ceiling insulation and roof space
  • Removal or top-up advice for old, flattened or patchy insulation
  • New ceiling insulation fitted to the current NZ standard
  • Even coverage with no gaps around fittings and edges
  • Care taken around wiring, downlights and access hatches
  • Roof space left clean and safe

The whole-home effect

Warm from the ceiling to the floor.

Ceiling insulation works best as part of the full picture. With a sealed ground barrier below, insulation under the floor, and a well insulated ceiling above, your home holds its warmth on every side. That is a home that is genuinely cheaper to heat and more comfortable to live in, right through a Wellington winter.

Common questions

Ceiling insulation, answered.

Is it worth topping up old ceiling insulation?

Usually, yes. Insulation from a couple of decades ago has often settled, flattened or been disturbed, so it no longer performs. Topping up to the current standard is one of the cheapest ways to make a noticeable difference to warmth and power bills.

Do you do ceiling and underfloor together?

We do. Insulating the top and bottom of the house at the same time gives you the biggest jump in comfort, and it is often more efficient to have one team handle both while we are on site.

How disruptive is the install?

Ceiling insulation is fitted from inside the roof space, so there is very little disruption to your living areas. Most homes are completed within a day.

Warmer at the top, warmer all through.
