Best Ways To Keep Your Whanganui Home Healthy and Dry
CEILING INSULATION FOR NEW BUILDS
We focus on ceiling insulation installation for new residential builds across the Whanganui region, utilising premium Premier Insulation Earthwool and Mammoth polyester products. Our skilled installers guarantee your new Whanganui home achieves Healthy Homes Standards and Building Code compliance from construction completion
UNDERFLOOR INSULATION
Underfloor insulation is vital for Whanganui homes, where the Whanganui River valley’s location and coastal influences create damp, chilly conditions year-round. We provide underfloor insulation installation in existing Whanganui properties with appropriate access (concrete ring foundations or accessible subfloors). Our premium polyester insulation products offer moisture resistance and deliver lasting thermal performance.
GROUND INSULATION
Whanganui’s river valley location and proximity to the coast mean ground moisture presents a consistent challenge for local homes. Our ground moisture barrier installation safeguards your underfloor space from dampness, mould, and condensation, creating a healthier indoor environment in your Whanganui home.
Our customer feedback!
Great service from start to finish. The team was professional, friendly, and easy to deal with. The insulation was installed to a high standard, and everything was left clean and tidy afterwards. Very happy with the result and would happily recommend them to others.

We had Insulation Tech install insulation in our home. Chris and Clinton had the job completed in two hours while Sandra, back at the office, promptly provided a quote, responded to our various questions and organised the job. We are very happy with the service and results overall.
