"After I fired my original Contractor II was introduced by a friend to Dimitri. From his attention to detail, professionalism and quality of work Dimitri is A++++ in my book and I would recommend him to anyone looking for a stress free renovation experience. I am a Contractor myself and would never hire anyone else to do all my finish work other than Dimitri because we share something alike. PERFECTION."

"I was extremely happy with Hank the owner of Standguard Security Inc. I called Hank early in the day for information about an alarm system and he promptly came to my house that same day in the evening for an estimate and other options that he presented to me for my needs. I called him back and we set a time for the installation of a new system that was free ( just needed to sign up for a monitoring service). The day of installation Hank showed up with his tech guy Chris and promptly started to get to work. Chris the tech guy / installer was great and made sure everything was working correctly and answered all of my questions before leaving. They both were professional and I am very happy with the whole process."
