Enviroflo came to do a free inspection of my drains. They were extremely helpful and went the extra mile in providing me with advice. Very prompt and professional. Highly recommended.
Amazing staff, great service, very happy with the overall experience. Would highly recommend
I was very impresses with the earthquake repairs done. I received clear information about the extend of work and the start date of every contractor involved. Good communication throughout with valuable advice. Thank you very much, I am very happy with the result!!!
We would like to express our appreciation for the work the Enviroflo Team has done to remedy our drainage damages. Shea has been very helpful and positive with great communication and supervision of the work. The various teams that have been here have all been a pleasure to have on the property. The asphalt team completed the relaying of the drive today. They were a great team to connect with and have completed a quality finish which has enhanced the entryway to our house which with the curbing makes a very attractive front of house appearance. Neighbours have commented on how great it looks. Thank you for all your work on our behalf. Very much appreciated. Regards, Leigh and Maureen
I recently have had work carried out by the Enviroflo Team, I must say the Team onsite work ethics were very high, they were very polite & respectful of my property, when the job was completed my property was left in a clean and tidy manner, Thank you so much
I recently had the enviroflo team around to repair damaged pipes at my property. Shea was an excellent communicator and kept me up to date with the goings on, the team left everything tidy and operational at the end of each day, they were a fun bunch of men to have around, extremely friendly and polite. The final result looks a million dollars....no more blocked drains for us. Would highly recommend
Enviroflo have made it such an easy and stress free process to have our earthquake damaged drains replaced. The property has been left looking better than before! Everyone we've dealt with, from the office to the guys on site, have been incredible. We would definitely recommend them.
Wow, Enviroflow were amazing. Not only did they check my drains for Earthquake damage but they found a blockage beyond my boundary so contacted the City Council for them to check their drains which they did, found the blockage was their problem. Wow service plus plus---and they didn't charge me.
My wife and I would like to say a massive thank you to everyone at Enviroflo Drainage , from the receptionist to the team of Shae and the crew. They went way out of their way and beyond of what we expected. We now have our drains finally fixed and able to pull up on our new driveway with the smell gone and job well done. Again we Thank you very much Enviroflo Drainage.
I would like to thank Enviroflo for the opportunity to have our drains checked for earthquake damage. When the result showed obvious damage to the drains, you arranged to have this fixed , and I appreciated that.
I would also like to express my confidence in your workers. Shea Reynolds, with his excellent communication skills, regular updates and management of the repairs, and Rudolfo, who did a superb job in relaying the uplifted tiled section which needed to be replaced after repairs. The result was correctly flowing water and a perfect finish in replacement bricks matching the original pathway bricks with a seamless reconnection to the older, somewhat uneven surfaced pathways.
A big thank you from Beth Ataria.
Absolutely efficient process from start to end. One week of inconvenience but worth it in the end. The end result was worth the wait. Very good tidy up.
I have recently had earthquake related stormwater and sewerage drainage repairs completed by Enviroflo Ltd. The work has been completed professionally, with minimal interruption to daily services and by staff who were friendly, courteous and always kept me up-to-date with progress. A job extremely well done by a company which has my endorsement and recommendation.
We recently engaged Enviroflo drainage to an inspection of our drains for any earthquake damage. Paul and the team were excellent with great communication and quick service. would highly recommend.
Top notch service and fantastic communication made this painless from start to finish. It felt like I was well informed and everything was explained my garden is in better shape then before they came and the visible drain work look's modern and sleek. Thank you to everybody involved
Enviroflo Drainage recently completed reparation work to earthquake damaged storm water and sewer drains at my residential property. Their regular communications which accurately advised us of their intentions and timelines for each phase of the work was much appreciated. The work completed was of high standard, was completed in a timely manner and utmost care was taken by contractors to ensure disturbance to garden and planting was minimal and considerable effort was made to restore the garden and concrete path on completion. All in all we were very happy with the work performed by Enviroflo and would not hesitate to recommend them.
Great experience dealing with this business, replaced all my earthquake damaged drains, great communication, very timely and professional, replaced the drains, concreated and hydroseeded the paved and lawn areas. Left it looking like new! Top job, highly recommend this business to others.
We are grateful to Enviroflo for the drainage repair. It was a huge job, handled very professionally. They took the burden of dealing with EQC off the homeowners' shoulders. Highly recommended. Lily and Bao
Work was completed on our EQC drain repair in a professional and respectful way, with camera inspection to complete drainage and driveway re-instatement. Communication was always quick from the project manager Andy, which made us feel confident the job was on track for completion even in the middle of some very wet weather. Thanks to the team at Eviroflo Robyn
A huge thankyou to all the Team and Enviroflo contractors who worked on our job. Everyone throughout the whole process were very respectful and courteous towards us and our property. I would love to mention you all by name as I met most of you, however in doing so would hate to leave anyone off "the list". Although our property was a building site, it was left in a safe and tidy manner each day. A very professional Company that we would be only too happy to recommend. Thank you all.
Enviroflo were a great company to be involved in my stormwater repairs. From the project manager, to the administration team and the men who did the hard cold work, they were friendly, honest, and courteous. Thanks - I was very anxious before these repairs were carried out, but am completely satisfied with everything. Robin Frew
A good team of workers, from the start to finish. Professional, adaptable and work in with their customers should there be any hiccups or queries along the way.
I wish to compliment the staff and contractors working for Enviroflow. We had significant EQC work carried out and were very happy with the process and outcome, on this job. The work was performed most efficiently. Communication with supervisors and crew regarding scope of the work involved commencement of work on time, reliability of attendance to site meetings and commencement of work were excellent. We greatly appreciated everyone’s accommodation and consideration to a sensitive site.
Thanks heaps for the excellent job just completed on our drains repair under the ACC contract. All of us three neighbours in Hoon Hay were most impressed with your men, their performance, consideration and professionalism which to us spoke heaps of their management. A great job. Many thanks.
Enviroflo just completed work on my property, after dropping a leaflet in my letter box. The process was seamless from first contact to finished work. They kept me updated all the way through of what was happening and the finished product was left in wonderful shape. (After original EQC work which was always not left in a good way). I would highly recommend using Enviroflo, fantastic work and well organized, and cant thank them enough
The team was really great and professional. They helped us navigate the EQC process and listened carefully about what we wanted and the different options available. The work looks awesome and we have had no problems. Many thanks to the team for doing such great work and helping to hold my hand through the process.
Enviroflow have repaired replaced all our stormwater and sewer pipes. Removed concrete paths and driveways and dug up the front and back lawn to get at them. All with minimal inconvenience to the people living inside. Replaced all the concrete and soil and sown new grass. Cleaned up so that the place looks even better than before they came. All the staff including project managers are very helpful and easy to deal with. Based on my experience with them I highly recommend this company.
Enviroflo has overall been a pleasure to work with! They put a leaflet in my mailbox making me aware that we could get our drains repaired for free if they had earthquake damage. If it wasn’t for that leaflet we wouldn’t have been able to replace our drains that weren’t working properly for free. Enviroflo were very accommodating to my specific requests and the guys on site were very experienced, had great communication and were easy to deal with. They let me put in extra services in the same trench and even a new water mains to replace my old rusty galvanised pipe. I 100% wouldn’t go with any other drainage company. Thank you very much
Your company has just completed work at my house/section. On the 27th and 28th July, I had one of your work men here to do all the work necessary to tidy up and replace bricks/paving slabs. He was from the Philippines, I found him to be a diligent worker taking great pride in his work, the completed jobs he did were a credit to him and your company. I just feel that we are too quick to complain about work, and not very keen to give praise where it is deserved. I also found the young gentlemen who did the actual replacing of the pipe work to be very polite, and hard workers.
