Excellent, I have used American Installations in the past and would definitely use them again in the future. They recently did a whole house blown in insulation. Their staff provided an exceptional experience from start to completion of work. They are always professional, courteous, and pay particular attention to detail. The quality of work was excellent. The job was completed on time. The workers always arrived on time and the job site was always cleaned up at the end of every day. Any problems or concerns were addressed in a timely professional manner and were followed through until resolved. Overall an excellent experience.
