Lorriane Mills. - Executive Officer, Roofing Association of New Zealand. April 1999
The most recent job was on the Auckland Central City Station, it was first class job that attracted plenty of good comment. We can highly recommend this company to any other organisation
Amos Selby. - Property Manager, NZ Fire Service Northern Region. June 1997
We recently used your product on our concrete paving and were very satisfied
Jim - Auckland. August 2021
Thank you for dealing with my error in ordering - your firm is a delight to deal with
Your product is 10/10 and your information you supply on your web page is accurate to the letter. Our clients are getting value for money with great results. With the many products that we have tried, Bio-Shield exceeds our expectations by far. And it has also gained the attention of our clients knowing that we are using a New Zealand made product.

Just wanted to touch base and let you know Dave treated our tiled roof a few weeks ago. We are super impressed with the results so soon. All of the roof is improving quickly, some sections are the best I’ve ever seen them. This is a bloody good product, I’d be more that happy to recommend it and Dave also. Easy process from quote to completion, Dave’s communication was excellent and a good rooster to boot.
Grant. Woodend. May 2021
This stuff is beyond awesome. I had really bad lichen on the roof. I honestly thought nothing would touch it. Two competitor products failed. This stuff worked miracles! Fantastic!
I have done several roofs here in Dunedin and there seems to be a lot of interest in it.
Love your product.
Simon. - Swift Wash Dunedin. May 2021
George. - Helensville. April 2021
Great product.Highly recommended. Can do larger area for less amount of BIO-SHEILD .Much better than all other over priced products I have used .Could see the effect of the product on moss and lichen on all my concrete and paved areas the very next day .Very effective when applied late in the afternoon when it's not sunny. Also very professional company to deal with and good advice from Andy. Was delivered in 2 days.
Andrudh. - Auckland. April 2021
I have used it on our drive and what a job it did. Incredible.
Bruce. - Waikouaiti. January 2021
I have purchased Bio-Shield to clean mould from timber retaining wall, house brickwork, concrete pavers and a concrete drive. I have tried other mould cleaners such as TMK packers and CRC from Bunnings but neither product cleared the black mould away. Bleach, water blaster and scrubbing did not work either.
You have once again demonstrated great personal integrity Andy. It's rare to find that level of honesty and integrity to be honest - so well done !
Mark. - Auckland. September 2020
Have used Bioshield and can highly recommend both the service and the effectiveness of the product. I use it on both our coloursteel roof and cobblestone driveways and paths.
I had a good result with 'wet and forget' on my concrete tile roof but a very expensive product. I must admit it was very easy to apply using a hose from the ground so i did not have to go on the roof. I am really hoping your product will work as claimed for a reasonable cost on my pavers etc
Rob. - Auckland. October 2020
Very happy with the results!
Geoff. - Napier. July 2020
Hi I Have purchased from you before Very happy with product.
Merv. -Hamilton. July 2020
Have purchased previously without creating an account. Product is so good, I need to open an account ! Thanks Andy and team.
Phil. -Hamilton. March 2020
On our property, I've treated fences with Bio Shield, water blasted once moss died and then painted the fence. I'm very pleased with the results.
Love your product. Thank you.
Maridy - Pukekohe. February 2020
I have used other well known moss and lichen cleaners on my concrete block fences but without a great deal of success. Two months ago I used Bio Shield and the change is already dramatic. I have a group of 13 restoring headstones and marble tombstones at a 150 year old cemetery here in Nelson in conjunction with NZ Remembrance Army and all of my group are complimentary towards your product. This cemetery is now starting to get a white glow
Brian - Nelson. Jan 2020
Best product we have ever used!
Simon - NZ Remembrance Army. Jan 2020
I admit your product nails wet and forget and they only get by with good marketing. We have some great before and afters (of the gravestones) for you if you need them. Hawera Cemetery was one of the best examples. We happy to do whatever we can, as on marble, your product is quite unreal!
Thanks Andy for advice over phone - nice to talk to someone who really knows their product.
Simon - Titahi Bay. December 2019
Paul - Tauranga. November 2019
Just received delivery of bio shield this is the 3rd lot I`ve had from you over the years.
We recently bought 5l from you ,it has worked - now need to do bach !
Thought I`d take the time to say what a great product this is at a affordable price in fact I just recommended it to the postie who asked about it, he said he`d been using wet & forget & wasn`t impressed with results.
Steve - Kaitaia. September 2019
Richard - Auckland. July 2019
Just wanted to let you know how well your Bio-Shield worked on the deck: it is a miracle how clean it is now compared to before when the thick layer of black fungus not only looked bad but caused a few nasty slips and falls. It is almost all clear now with a bit of brushing and the weather.
I have referred many people to your brand. The best results we ever got was on a property right on the shores of Lake Rotoiti where the house etc were constantly under the shade of trees.
The perfect setting for grunge to grow. An incredible transformation.
David - Whitianga. May 2019
Mike - Rotorua. February 2019
Bio-Shield is fantastic. The teak deck on my boat has never looked better. So easy to work with and no adverse effect on other materials. I am now also using it on my house – roof and terrace etc.
Per - Blenheim. November 2018
Wary of an unknown product, Andy answered all my questions. We were ECSTATIC at the effective job Bio-Shield has done removing "green growths" on all our concrete areas in Oct. 2017. Bio-Shield's price based on their dilution rate prices it MORE than favourably against the heavily marketed products at hardware stores. We're confidently back today for our second order to tackle the roofs of our 4,000 sq.ft home.
Alison - Auckland. January 2018
Thank you for the work done and the expert roof inspection you did and with the brochure details of the RANZ. You could set you up as an independent roof inspector who people can trust. And increase your fee accordingly than just the Bio-Shield treatment you did for me. There is a desperate need, especially in Auckland, to find honest and trustworthy trades people. As I hear from many!
Jan - Auckland. March 2018
I have used your product for removing lichen and moss from headstones and it works brilliantly. Recommend all monumental masons use your product.
Ian - Maiden Stone Ltd. March 2018
It is really good stuff - my 2nd lot from you, to now go and spray my parents paths.
hi had reservations about bioshield, having not used the product before.
Charles - Dunedin. October 2017
main reason for buying was you guaranteed it would not harm my clients coloursteel roof.
well the product did not harm the roof and did kill the fungus over time and the roof looks great
nice product guys, will recommend to my other clients
Ric - Whangarei. March 2017
Thank you the product arrived and my roof has been sprayed and completed, great price, great service and so easy to use. Cheers
Just thought I should send you an unsolicited note to say how impressed I have been with your product Bio Shield.
Steve - Waikanae Beach. February 2017
Quite apart from use around the home, we have this 120m alloy start structure in lake Karapiro that requires a seasonal spray to keep it in tip top shape.
Worth some $500,000 to replace I can say that 3 weeks after spraying it looks as good as when it was built 8 years ago. Great and inexpensive product.
Peter. - Karapiro August 2015
Your Bio-Shield is a great product, I bought some a few years ago then threw the empty container out before ordering some more. Therefore I didn’t have your details and I ordered a different product from another supplier by mistake.... Big mistake, it wasn’t a patch on yours. Thanks again.
Tony - Mangawhai. July 2015
G’day, Just thought I'd send you a couple of pictures of how well your product worked on my tile roof. We are very pleased with the result as you will tell from the pictures and have had no problems recommending it to our friends. The before pictures were taken on the 29-7-15 and after 19-3-16 All i did was mix it up and spray it on.
Thanks for the great product.
Warren and Robyn. Gloucester, NSW. March 2016
Found the BioShield at the door this morning - WOW
I would like to thank you very much for this, it really is most appreciated.
As you can probably noticed (if it was yourself who delivered it) I have
large areas of "paved" surfaces which require constant attention.
I switched to BioShield a couple of years ago and find it the most economical product that I have used to date. Once again many thanks
Phil, Auckland. July 2016
here's some product feedback - that Bio-Shield is bloody marvellous stuff, I wish I'd come across it years ago.
Regards, Ian, Whangarei. March 2016
I was concerned at a lack of progress, I really was. But 8 months later, my terracotta tile roof looks brilliant. Well done. Good product, good value.
Phil. Coorparoo. QLD Lune 2016
Thanks Andy, It worked extremely well. We will be back for more in the future.
Mark - Auckland. January 2015
Parcel arrived this morning great service and great product thanks.
Lyn - Dunedin. July 2016
Hello Andy, ...very efficient....it's great stuff!!! Thanks
Kathleen - Wellington. June 2016
Thanks Andy, This is the third bottle of Bioshield I've bought and found it to be really effective.
Stephen - Hamilton. August 2015
I didn't think that Bio-Shield would work on our driveway because we live in the bush in Titirangi but I am thrilled with the results and our clean driveway
Gail. - Titirangi, Auckland, January 2011
I got some bioshield off you a couple of weeks ago to do my driveway in titirangi. I had a few litres of Wet and Forget to use up at the same time so did half with Wet and Forget and half with bioshield. Because of the heavy rains last week I got a result pretty quickly and I cant see any difference in effectiveness of one product over the other.
Darryl. - Titirangi, Auckland, July 2013
You would be the easiest person on the planet to deal with. Appreciate your help and advice and prompt attention.
Denis. - Kewarra Beach, Queensland, February, 2016
Very impressed with your service - straight up and effective, yet with none of the gimmicky sales BS that I think most people get sick of hearing
Gavin. - Palmerston North, July 2012
The job was carried out to an extremely high standard, totally professional, no fuss, nothing was problem.
This sort of service is without a doubt outstanding and I would have no hesitation in recommending your services and product to any prospective customer.
W Lewis. - Challenge Realty, Auckland. May 1997
I can highly recommend as can Michaela the use of "BIO SHIELD" as a concrete and roof cleaner.
It works a dream. This product is also a much cheaper solution to any other similar type cleaner.
I rang and ordered some, it arrived the next day. Michaela had a part of her drive that was extremely infested with mould and such like, she did a 15-1 mix for that area and now it looks like new, like the rest done with a 20-1 mix.
Mike, Rotorua, October 2013
Just wanted to let you know that I followed your instructions for soaking the tipi and the results are very pleasing. On the first day the side that gets the most sun all the mould disappeared and after four days the mould was completely gone all over and has stayed gone to date. Very impressed. Thank you.
Annette, Bay of Islands, Feb 2015
Bio-Shield arrived 7am this morning, great service and great product.
