"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."

"Joshua has done a lot of work for us over the last year - from replacing blinds to fixing faucets, toilets and installing light fixtures, smoke alarms, shower fixtures, etc. His work is always excellent! He is very prompt, reliable, and does a thorough job. I was thrilled to find such a great handyman since we had to move and rent out our house. The only problem is that his schedule is very busy because he's so good!!

"My decks were in disrepair and had both stains and cracks which needed to be addressed. The business owner and crew were here daily and in a timely manner. The work was completed on time and as promised without issue. All work was explained thoroughly and the color choices were presented to me. I appreciate their efforts to be sure I was satisfied with the job and I feel confident in recommending Ultimate Concrete. "

"I had a lot of cracks that needed filling before the seal coat was applied. They did a nice clean edge job. The price was good and I will definitely use them again before it gets so bad next time."

"Juan did an excellent job. He called me right away after I placed an internet request. He leveled our area and planted sod. He was reasonably priced and was able to do the job very quick. It’s been 1 week since he planted the grass but it looks great!"
