"Very professional. Arrived when promised, and assessed the work needed. Their estimate was not within my budget. I was able to find a handyperson to take care of this, instead."

"CJR is all about quality, they treat you like a real customer. The team is extremely professional, they clean the site daily before leaving for the day. You and your neighbors will not even notice its a site under construction. The quality of work is far and beyond your expectations. I will continue to use CJR for upcoming projects and referrals to all my friends and family."

"Home Advisor does not have the specific category for the work that was performed of replacement of graded retaining wall up my driveway and around a structure. The work utilized excavation, concrete, wood & construction. Cristian, the owner, was the epitomy of professionalism as with every crew member. Firstly, he did not try to sell me on something I did not want, much appreciated. The job was meticulously executed in record time at the price I could pay. This job has been on my bucket list for years... finally completed with a job well done!"

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."
