"Perfectly. Carl met with me for a challenging problem/project I had previously hired (years ago) another contractor to solve/install. It involved installing a natural stone “stairway,“ with landings, on two small hills. The previous contractor did not succeed. Carl assessed and knew instantly what needed to be done, gave me a reasonable price, communicated effectively, always showed up on time with his crew and, at the risk of sounding hyperbolic, did a perfect job. Every member of his crew was customer and project focused. I already plan to welcome them back for another project elsewhere on my property."

"I contacted them to a dug up the floor and a separate plumber will be hired to replace a leaking pipe and and Service Team Professionals would have to put the floor back. I have submitted all the documents from the insurance company, that has all my contact information, and after they've reviewed the documents they called and said that they couldn't do the job because, they would not make a profit out of the project and they don't do the work despite me having the extra money for the project. After speaking with Christina, the receptionist, Phil whom I believe is the owner of the company got on the phone and stated that do I expect him to do **** work for free, and so I hanged up, and he called right back cursing and so I hanged up on him again, then he called the 3rd, afraid that he would curse me again, so I never answered the phone anymore."
