This was essentially a perfect purchase and installation. Dan arrived in the midst of winter for the estimate....when he really couldn't see everything because of the snow.
The crew arrived on time, Central Maine Power was early, and work got underway on time. The installation involved trenching across the driveway diagonally for about 50ft. The work was flawless and when I arrived home I could hardly tell the driveway had been disturbed.
The crew was friendly and professional....calling me mid-job to make an adjustment to the tank placement, resulting in a much better looking result.
First class all the way.

I chose Mid Maine Generator for my new Kohler standby generator based on the very professional site survey and proposal they prepared. The real test, of course, was on installation day. When the three man crew arrived for my two-house generator install, they got right to work with each man clearly knowing his duties and performing them in a very professional day. When the job was done, you wouldn't have even known that they had been here, except of course for the new generator and transfer switches. All of the trenching (propane, electrical to both houses, etc.) wasn't even visible..... they had carefully hand dug the trenches, being careful to keep the sod intact, and had replaced the sod so that the new trenches couldn't even be seen. This is the neatest job I have ever seen any contractor perform in all my years of having them work on my house. Sure, they had a lot going on during the day but, by the time they left, every spec of mess was cleaned up perfectly and the lawn was restored to perfect condition. I highly recommend Mid Maine Generator.

An amazingly positive experience working with these professionals to have our generator installed in Boothbay Harbor. Respectful, timely and attentive ... given that we are on hour 9 of no power, we are also most grateful! Thank you Mid Maine Generator!

Highly recommend Mid Maine Generator. Very competent and just plain nice people!

Toby Ramirez

From the very beginning, the quote, the explanation of what they would do, to the install was nothing but professional. Steve and his crew were on time, on budget and cleaned up after themselves, I cannot tell you how impressed I am with this company. I didn't think this type of service existed any more. You will not regret doing business with Mid Maine Generator!
