Thank you excellent delivery as always, now I have no excuse to start Spring cleanup. Love this product and
have recommended to others who have also found it great.
Hope this time the hose bottle will make it even easier.

We’ve been using Bio Shield for a few years with great results controlling the lichen build up on our roof tiles. It’s a great product. It’s good to know there’s companies out there that actually deliver on their promises.
Barry. Sydney July 2023

Spray it on and let Mother Nature do the cleaning. All of our sandstone retaining walls are just like they were newly installed. The lichen on our glazed terracotta roof is nearly all gone (just need another spray next month). Brilliant product, thanks Andy.
Charman. June 2023

Hi, bought this product in 2019 to clean Polycarbonate roof, absolutely brilliant, time to redo.
Thanks for a great product.
Jeanette. Boronia October 2022

We had a large coverage of lichen on our skylights in the fernery, looking from underneath it was terrible.
We followed your instructions and applied the Bio-shield - being sceptical that it would work.
Applied the two coats and then washed it off.Â To our surprise it just fell off and a clean surface shone before our eyes.
John. Kurunjang. January 2022

We used your Bioshield on a roof in Wollongong NSW with great results
Trish. Wollongong. June 2021

Bio-shield delivered this morning.
Have used this product in the past with great results.
Thanks for the prompt follow up of the original order.
Chris. Glass House Mountains. June 2021

Our clay tile roof was infested with moss and lichen. We attempted to clean it with a pressure washer but there was a significant risk of water ingress and so we stopped. A couple of years later, 2020, we tried again but this time with the Bio-Shield product. there was a small improvement. We sprayed again about 6 months later. There seemed to be some improvement and so we arranged to spray again. The roof was first blown and then the roof looked almost new. We will repeat regularly.
Jack. Melbourne. March 2021

It's not often that a product lives up to the manufacturers advertising. All I can say is that i had my doubts after applying 2 other types of lichen removal products to my lichen covered colourbond roof which had limited affects. I applied bioshield as per instructions and nothing happened for a few weeks but now after several months my roof is completely free from lichen . I'm amazed.!
Excellent product and it was delivered within 2 days after ordering
Peter. Launceston TAS January 2021

Just a short note to thank you for your prompt service.
An order placed on Sunday delivered to my door by DHL at lunchtime on Wednesday.
Unbelievable service from NZÂ to Australia in 3 days. Arriving on the date promised.
Many thanks.
Michael. Goulburn NSW December 2020

Bio-Shield worked so well on our home that we are now going to use it for our local community hall.
Mark. South Riana TAS June 2020

Just wanted to say how thorougly impressed I am with Bio-Shield. All the claims you make on your website are true. The product works great. The Jet-Stream is a real time saver.
The only thing more impressive than the product is the delivery. Only days to deliver from NZ to North Queensland.
Don't normally write this sort of stuff, but was compelled by the quality of product and service.
Ken. Mount Sheridan QLD April 2020

Our tiled roof had a lot of black mould area's making it look terrible. We researched Bio-Sheild and decided to give it a try. It's done wonders over the past few months!!! So glad we tried it. It was easy to order and arrived promptly. We are very happy customers. Thanks Andy!"
Kim. Iluka NSW, February 2020

Just to thank you for the moss remover; I have already been up on the roof (not bad for an 86 years old) and was very impressed as to how the attachment spray worked. I completed about half the roof in about twenty minutes. I have enough spray left to do another part of the roof when the weather get a bit cooler. Once again many thanks.
Doug. Rosanna. VIC March 2019

Gâ€™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 19-3-16Â All i did was mix it up and spray it on.
Thanks for the great product.
Warren and Robyn. NSW 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 June 2016

Thanks Andy,
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

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

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. Jan 2017

Over the past week the Association has been contacted by two of your customers who called to convey their gratitude and compliments on the high standard of workmanship and customer service you provided to them.
I would therefore like to congratulate you, this has reflected well on not only your reputation but on that of the Association.
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

hi had reservations about bioshield, having not used the product before.
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 - 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
Steve - February 2017

Just thought I should send you an unsolicited note to say how impressed I have been with your product Bio Shield.
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. - 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 didnâ€™t have your details and I ordered a different product from another supplier by mistake.... Big mistake, it wasnâ€™t a patch on yours. Thanks again.
Tony - July 2015

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.Â Â
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'sÂ some product feedbackÂ - that Bio-Shield is bloody marvellous stuff, I wish I'd come across it years ago.
Regards, Ian, March 2016

Thanks Andy, It worked extremely well. We will be back for more in the future.
Mark - January 2015

Parcel arrived this morning great service and great product thanks.
Lyn - July 2016

Hello Andy, ...very efficient....it's great stuff!!! Thanks
Kathleen - June 2016

Thanks Andy, This is the third bottle of Bioshield I've bought and found it to be really effective.
Stephen - 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. - 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. - July 2013

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. - 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.Â 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. - 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.
