I needed another 5,000 gallon tank added to our collection system. They were able to do it in a timely manner, for a fair price and I would recommend them wholeheartedly.

Matt, Our new gutter system finally received a real tester of a rainfall and worked great! Thanks for a good job!

Harvest Rain was highly recommended to us by our neighbors, as they recently had a complete rainwater system installed and we were wanting to update our filter board. From the initial visit with Matt for an estimate, till the installation of our new filter board, I found the customer service to be outstanding!! All my email questions were answered in a timely manner–and scheduling the install was very easy–as they were willing to get us scheduled ASAP—even though this job was much smaller than the the larger complete installs. The estimate was reasonable, the crew showed up on time and were very nice, yet professional and I highly recommend Harvest Rain and plan to use them in the future for all our rainwater needs. Thank you Matt and your entire team!

We have rainwater harvesting system that was installed with our house which needed some work. Denver and his team quickly diagnosed the issue and fixed it. Harvest Rain has recommended some upgrades that we are now evaluating. Great company to work with.

5.0 star rating 3/30/2015 I called Harvest Rain to install a rain collection system to use for our church food pantry garden. Denver was wonderful to work with and very professional. Items that he had included in the written estimate, but felt were not necessary when doing the actual installation helped lower our final cost. The system works very well and we hope is just the first phase of a larger rain collection system. Would I use Harvest Rain again? Definitely!

My friends have been after me for years to do a rain water collection system. I decided this was the year and I began calling around. There were a several companies I called and while most were interested only Harvest Rain returned my calls, met with me and submitted a bid on time as promised. They followed through with great ideas that were well executed in the most professional and timely manner. I now have a rain water collection system of which I am very proud. I would most highly recommend Harvest Rain to any who wants to do the right thing.
