I recently did a whole house renovation to my home in Asbury Park NJ, it was a dirty 6 mo project, the dust from the plaster and lath removal, floor sanding, new drywall and insulation made its way into every crack and crevice in the house and of course the duct work, plus the 97 years of dirt that was in there before we purchased and renovated, the techs from Advanced did an awesome job, James and Albert arrived on time, they were very professional and well informed, they also provided me with the before and after photos that were taken while preforming the task, Job Well Done ! ! ! Thanks ! ! !
