Real Customer Reviews about Our Indoor Air Quality Services

Wanda W. On 1/18/19

Remediation Work by Flag Enterprises
Flag Enterprises are total professionals. They thoroughly inspected the area, expertly advised on what type of remediation was necessary, removed all damaged areas and cleaned the entire site. They were always on time, always in contact with me and fully informed me on all their work. Tom and his crew did a remarkable job, professionally and quickly. Couldn't ask for a better experience with them. Would easily recommend them to others.

High quality service.....very trustworthy!
We recently had a severe mold condition in our basement. I reached out to flag enterprise after speaking to different companies. Flag was professional and honest. From the beginning to the end they reassured me that everything would be taken care of. They displayed such a high quality of service and talked me through the entire process. The job was neatly and in a timely matter. I would highly recommend them to anyone.

Amy E. on 5/1/2019

Flag Enterprises helped me after my air conditioner condenser flooded and made a 6' x 6' hole in my ceiling on Memorial Day weekend. I was distraught and worried about mold, reconstruction, and expense but they were fantastic! They were professional, efficient, did meticulous work, cleaned up and left things spotless and made sure that everything was bone dry with no mold. Even better, they dealt directly with my insurance company so I didn't have to worry about anything. They were completely accessible and responsive even over the holiday weekend and I was very grateful for their kindness and willingness to help. I highly recommend Flag Enterprises.

Frank G. on 4/1/2019

We had Flag do a mold cleaning job for the attic. They did a good job. More importantly, their price is fair.

Dawn F. on 4/17/2019

Extremely through job in removing the mold! Many vacuum machines running continuously and the house has never had it back again. I would recommend this if you have flooding in your house!

NicciZ Z. on 3/24/2019

We had an overwhelming amount of water and mold due to roof leaks and broken pipes. Gary and his guys walked us threw the process necessary to dry the house out and rid of the mold. Never felt as if I was being talked down to or being had, which as a woman still happens more often than not. I highly recommend and would use again. The house was good as new, no better when all the work they did was finished. Thank you Flagg Enterprise.

Indira M. on 4/7/2015

Post Sandy I did air quality testing and found that I had mold. I did research for days and had multiple consults and found out that many companies had no clue on how to treat mold. Flag Enterprise was recommended by a friend and they were great. They also guaranteed their work and post remediation I retested the air and the quality was close to perfect.I paid 50% upfront and the other 50% after the air quality test. This is the first time that I have taken the time to review any company/product but I feel very strongly about this company.

Ashley B. on 3/16/2015

We had a leak in our basement which resulted in mold everywhere! I am not from the area and Googled someone flag came up and I called them. Absolutely no disappointment.. they cleaned the area removed the mold and I haven't had a problem since. And if I do, they'll be the first I call and recommend to everyone.

Sandi L. on 3/29/2019

They did a great job. They came quickly and worked carefully. They did everything they could to ensure that the water damage was handled properly so that mold would not grow. They were friendly and knowledgeable. I would absolutely recommend them again.

Virginia L. on 2/13/2019

When our boiler burst a pipe during a blizzard and flooded the basement with hot steamy water for 5 days in Feb. 2019, we were referred by our insurance company to Flag Enterprises for clean up and restoration. We had damage not only to the basement, but also to the first floor of the home due to the steam rising from the basement. A team arrived the next day with all the equipment needed to clean out and sanitize the basement for mold/mildew and fans to dry out the basement and the first floor. Once that was accomplished, we had different teams that came to restore the dining room wall paper, paint, and refinish the hard wood floors. All work was done in a timely manner. The personnel were very polite, conscientious and professional making sure that all repairs were made to our satisfaction. They arrived promptly as scheduled. We were very impressed with Flag Enterprises and highly recommend them.
