GJ Gardner Homes – Manawatu/Horowhenua has engaged A’line Group to supply and install Spouting systems on our homes for the past 6 yrs. We have found them to be very professional and competent in every aspect on their business, and enjoy the business relationship we are experiencing.

Just a quick message to say thank you so much for a very timely installation of our spouting on Wednesday. Both my husband and I were very impressed with the three young men who did the job for us. They were very professional, efficient, tidy in their work and cheerful. They completed the job much quicker than we expected and we are very happy with the end result. We would have no hesitation in recommending your company to our friends.

Just a quick email to say that we are very happy with the spouting that was installed, it looks fabulous, you were both polite and helpful and went above and beyond to make sure that all aspects of the job were as they should be, I think your employer should be very proud to have you working for him, thank you very much.


With regards to the work carried out yesterday, I would just like to commend the work of the lads. Excellent work ethics, and a great attitude throughout a very long and a great attitude throughout a very long and trying 12 hour day! Very professional and much appreciated.


Have been meaning to send you and email for a few days now, to thank you and your team for the very professional outstanding job that your team completed on the spouting for our new house. I was very impressed with the job that had been done. With all the tradesmen that have been working on the house your team are by far the best we have had and only wish more people could work to the standard and time frame you guys do. I never got a chance to see the guys on Friday, can you please thank them…


I would just like to say that the two guys that did the job were just fantastic, they did a great job and were also extremely friendly, thank you.

I recently acquired the expertise of Streamline to clean my gutter system at home and was very impressed at the level of service I was offered. It was completed within a great time frame and I felt the workmanship was reliable and efficient and wouldn’t hesitate recommending them.


Thank you for your quote for the removal and replacement of spouting on our property. Yours was not the only quote we sought, but I was impressed with your professionalism, communication, and we are happy with the price. We would like to go ahead with the quote. Thanks again for the service to date. I look forward to speaking with you in the near future.


We would like to take this opportunity to thank you and your team for a job that  equals total satisfaction. The finished spouting is first Class – Definitely superior in all respects  to the former Klass system. As I said to you “You reap what you sow” and your seed – both personnel and product cannot but produce goodwill We are both grateful and happy to recommend your company to all.

This message is to let you know that we were provided with outstanding service by your tradesmen. The guys were reliable, courteous, friendly and we are very happy with the new spouting and downpipes. If we know of anyone looking to have spouting work carried out, we would most definitely recommend Streamline.
