Contractor reviews from customers on Google

  • "Terrible company to deal with. Every job is just that, another job to them. Terrible communication, for $30,000 i cant even get a call back about fixing little issues. Have called multiple times, spoken to i dont know how many people and still have yet to receive a call back. Typical company where its clients are just another paycheck to them. You deal with 7 different people within the company with zero accountability and communication between the employees. Extremely unprofessional and would never give them business or recommend anyone to them."

  • "Terrible customer service. Called 3 times in 1 week and still had to wait another 2 days for a call back. Quick to take your money but if you need repair they messed up they take forever to come out to honor thier job. Last time I spend 20k with them"
