Customer Reviews

I have dealt with Jeremy for my AC and now Stephen for my sewer issue and they are wonderful. I called this company because they have 24/7 service and i was desperate and they came thru very timely and professional. I have to to get my sewer line replaced so i will give another review once that is done.

GREAT SERVICE.....GREAT WORK!!!! I contacted Spengler Company to do some bathroom remodeling for me since they had done some water heater and a/c unit work for me in the past. Since I was impressed with the work done then, as well as their professionalism, I decided to contact them for this project as well.
