What our clients feel about us…

I just wanted to see what a fantastic job the guys did today in the ceiling and underfloor.
They arrived promptly at 8am and tidied up after themselves.

Ben extremely organised and very polite.
The guys had to cope with an Earthquake which wouldn’t have been nice.

The contact with Greendog has been A+++ all the way through.

Ducted heating and additional heatpump installed a couple of weeks before.

Thanks Rob too for all your excellent follow-up.


We had GreenDog install wool insulation at our property on 23 February 2012. We would like to thank you and your team for a great experience. Good professional and friendly service are scarce these days and we cannot fault the service we received from the beginning to end. 

  • The initial phone call provided good information with friendly staff.
  • Nick was around to promptly to measure up and provide a written quote.
  • On installation day Ben and Craig (very nice guys) rang to advise they were running a little late as the truck had a flat battery which was very much appreciated
  • After discovering on the quote that the pipe lagging on the top of the hot water cylinder had not been done I rang the office and the boys came back promptly and happily!
  • The follow up with the Steve was also very good, and he phoned to ask if he could come earlier which was also appreciated.

 The staff you currently have working for you are a great team. Please pass on our thanks to all involved and if we hear of anyone wanting wool insulation we will be sure to recommend GreenDog Insulation.

Kind Regards,

Graeme & Steph Remington

My Sincere gratitude for insulating the bats in my home. I can notice the warmth, and am very grateful for the men who installed them, and want to acknowledge community energy action.


The guys were great and the installation all went very smoothly. My house is now lovely and warm.

Phillips Black

Thanks for sorting out the insulation for me. 

My daughter reckons its a lot warmer now.

The guys did a really good job, really happy with the work.


We had Green dog put the under house insulation and damp proofing cover under our rental property. They did an great job and were very efficient and reasonably priced. Highly recommend them and what an awesome Team to donate for a very worthy cause.

While living in a two bedroom unit last year we found we had severe problems with condensation every morning and decided to research ways to combat it. We priced and studied systems from three companies and found the one we believed most suited to our needs. For cost-effectiveness and efficiency could be supplied by GreenDog Insulation.

We found the company pleasant and helpful to deal with and the unit we selected was installed promptly and at the cost agreed. The morning after the unit was installed we found there was no evidence of condensation on the windows and this continued throughout the winter.

Recently we moved to another house of comparable size and we have had no hesitation in approaching GreenDog Insulation to install another unit. Once again all dealings with the company have been conducted in a friendly and efficient manner. For a warmer healthier home we recommend you to contact GreenDog Insulation.

What a lovely surprise to receive a box of chocolates from you guys thank you. We were very happy with your service, from the first phone call I made to you through the assessment and the installers of our new insulation and guy who came to check it all out. Top marks to all of you. And yes we have noticed a difference, our living area holds the heat better, even with our cursed 14 downlights.

Neil and Doreen McEwan

Thank you for the professional and efficient way that you informed me of your insulation options. I am in my sixties, and now I have a warm open living plan dining room, and kitchen area which now keeps me warm, even on the coldest of winter nights’ with just 1200 watts of an oil electric heater. Last winter, it took me 2200 watts of the same heating source to heat that area… so I am well pleased. 

Rachel Ryan

I just wanted to thank you all for a wonderful job. We are happy and will definitely recommend you to others.


I would like to take this opportunity to thank you for all for your professionalism and a job well done on our property.

We will without a doubt gladly recommend your company to anyone requiring insulation.


Lyn and Darryl

Custome had Environment Canterbury around for a quote to do the ceiling and had to check the underfloor out. They quoted “You wouldn’t get a better job anywhere else, they have gone beyond the expectations”.

I just want to say thank you for the great job done by Jon and Aaron yesterday, they’re a great couple of guys that seemed to enjoy the work and it was a pleasure to have them around. Courteous, tidy and very informative on their product. I would highly recommend them and wish them all the very best.

We have a practice of tipping people we are impressed with… this was very graciously declined. Jon and Aaron are a true asset to GreenDog Insulation. 

Edwin Kidwell

A big thank you for the job and the workers – they were really professional and the house is so much warmer. 

Browyn Leek

The installers were very thoughtful, hardworking and did a great job. I also want to thank everyone involved for making it possible as I would never be in a position( the property managers’ couldn’t care less) to do the batts himself and what a difference it’s going to make going forward.

Allan Morrison

GreenDog installed our underfloor and we are very happy with the price and service.
