"I interviewed six solar companies and got bids from three. Charlie of Landmark construction & energy crew stood out much more above the other companies that I spoke and met with. He is responsive, always returned my calls quickly and he does what he says he is going to do. Charlie came over to my house and met with me before installation, during the installation and after. In addition he worked with his crew at the beginning of installation to make sure everything was perfect with a tricky area of my roofline. Above all of what I wrote above, Charlie and the office staff are very organized people. Charlie was able to provide me with a lot of information about rebates, taxes etc… and Every bit of information I could want related to monitoring my system, working with Landmark construction & energy crew, maximizing the cost benefits, and getting my tax rebate, are all gathered and clearly labelled in a binder. Charlie knew how to explain everything about solar and I could see during our meetings how much patient he have. Charlie didn't have to push anything in order to sell his work to me because his product was the one I wanted, it made sense, and the price was better than others. I can't think of a contractor and I've worked with quite a few once in the past and for this project, I met with several ones as well and Landmark construction & energy crew is more reliable, efficient, and customer-oriented. Thank you, Charlie!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

Communication was great his suggestion to improve the design defiantly made a great difference! Wow, what a great job they were done! I am fully satisfied with the results and highly recommend Ocean Seven Builders."

"It was an amazing experience. I dont think there is a better company I could have picked for this job. The contractor was really professional and made me feel comfortable the entire time. They also made me feel part of the project which was awesome they let me get involved as much as I wanted which made this whole thing even better and more enjoyable. They also didnt get frustrated with me at all which i know can be hard at times because I know I can be difficult when it comes to having things how i want them. Thank you for a wonderful service !!"

"Joshua is great! I purchased the toilets at Home Depot and arranged for Joshua to pick them up. Well HD Lancaster location only had two of the HE toilets that I wanted, so the 3rd toilet was picked up in the HD Palmdale store. Joshua did all this with pleasure. He was on time, work was completed superbly and cleanup was on point. I will always call on Joshua for my Handyman needs..."

"Darnell is very professional. We have young children and I very much appreciated that he and his crew were on time everyday and cleaned up every day after they left. Communication was easy with both him and his wife who primarily does the scheduling. The price was outstanding and we would recommend them to anyone who is looking for a general contractor in our area.
