A Smart First Upgrade for New Homeowners

What a Full Upgrade Typically Includes

A full insulation upgrade usually covers the three key areas that affect comfort and energy efficiency in a home.

Ceiling insulation

Heat rises — and older homes often lose huge amounts of warmth through the ceiling. We assess what’s already there and either top it up or remove and replace it so the insulation performs properly long-term.

Underfloor insulation

Cold air sits under the house and moves up through timber floors. Proper underfloor insulation makes floors noticeably warmer and reduces draughts throughout the home.

Ground Moisture Barrier

Even when soil looks dry, it constantly releases moisture vapour. A ground moisture barrier stops that moisture from rising into the subfloor, helping keep the house drier, healthier and easier to heat. Done together, these upgrades make a dramatic difference to how a home feels and performs.

Providing an expert, all-in-one solution

Perfect for New Home Buyers

We do a lot of work for people who have just purchased a property. Often the insulation technically exists - but it’s old, patchy, or barely doing its job. A full upgrade early on means you:

Highly Recommend Alex's Team - Professional, Fair Price, and They Get the Job Done! Alex helped us three times now, and every experience has been superb. Job 1: A single room's roof insulation. The space was so narrow that many companies refused the work, but Alex managed it perfectly and gave us a very fair quote. Job 2: He helped us to replace the insulation for our entire roof. He expertly removed all the old material and installed the new insulation flawlessly. Job 3: Most recently, we needed crawl space moisture barrier and insulation. Our under-house area is incredibly tight (less than 50cm), and again, many companies told us it was impossible. Alex's team tackled the job and completed it to an excellent standard. This team's ability to handle the most challenging, narrow spaces shows their high level of professionalism and skill. Their pricing is also very reasonable for the quality of work

So happy with my insulation job completed by Alex and his team of professionals. Alex responded to my enquiry promptly and my job requirements with some different options which gave me choices and all at very good pricing . His team were punctual, incredibly polite and friendly and extremely efficient. They over delivered and left the property in a very tidy and clean condition, taking all their rubbish away with them. I would recommend Kaiser Insulation to absolutely anyone for price, efficiency and service with a smile. The PS3 and Branz information were provided promptly at the end of the job in time for the inspector. Well done guys! and Thank You So Much Alex. You are running a great business!

Alex, Simon & Alesana. Three of the nicest guys you will meet. Alex gave me an unbeatable quote, and some great advice. His pleasant nature made me feel I was making the right decision. Simon & Alesana, who were so friendly and respectful, then did an amazing job on the installation. On the very first night I could feel the difference in the warmth of my house. I am very happy with my insulation. Take care guys, and thank you!

We had an amazing experience with Kaiser insulation team on our 1910 villa! Alex, Simon and Alesana were incredibly friendly, professional, and clearly took real pride in their work. Everything was done with great care and attention to detail, the install was super tidy and neat, and they left everything spotless. Along with a great service, the pricing was competitive. We’ve already been recommending them to friends and will absolutely use them again in the future. Couldn’t be happier! If you are looking for an insulation company, look no further, these are your guys!

Alice

Alex from Kaiser Property helped me install ceiling insulation in order to achieve Healthy Homes Requirement. Alex had exceptional communication and was able to provide me with a competitive quote compared to that of other tradesmen from builders crack. Alex turned up on time and completed the job in the timeframe he previously discussed. Alex upgraded my quoted insulation spec to a superior product free of charge. The installation was very professional. Could not recommend more!

Really happy with the work that Alex and his team did with installing underfloor and ground moisture barrier at my house. Very professional and efficient from giving a quote to completing the job. The price quoted was very competitive and he also charged me less after the job completion as the job was less than the quoted measurement which shows his honesty. Highly recommend Alex and Kaiser Insulation for any insulation job.

Is a Full Insulation Upgrade Worth It?

For many homes — especially older Auckland properties — the answer is yes.

Insulation upgrades are one of the most cost-effective improvements you can make to a property. They improve comfort immediately and continue paying off through lower heating costs and a healthier indoor environment.

If you’ve recently purchased a home, it’s one of the smartest upgrades to do early.
