Additional Service Area: Portions of Lee County.
"Dishonest and poor workmanship. Hired to remove and replace deteriorated framing. Contract was signed to be billed on a time and material basis. Hours billed was to include only travel time from their base in Sycamore to my property (20-30 min), pick-up of project materials, and work performed. I purchased all required project materials, per provided list. I was assured that all of my calls and questions would be answered before, during, and after work is completed, however owner, Theodore C., has been refusing contact since I signed the contract. Work took them 5 weeks, yet they worked only 14 days during that period, putting work on hold multiple times to start work for other customers. I complained multiple times about the crew not working, instead spending ~30 min every hour smoking in their truck or north side of house. A large section of wall, 10-15 feet in length, was left open for an extended period of time (roughly a week). This left my crawlspace exposed to the elements (this was during a period of frequent rain), as well as animals. Despite my crawlspace being encapsulated, I am still working to combat the moisture present from their negligence. The completed work is unsatisfactory, as it is out of level with large open gaps (you can see light comming thru), and I cannot be sure if it is even safe. SD representative, Denny S., was supposed to have filed a permit with the City of Elgin (signed by me same day as I signed contract) and had stated that he had the permit on hand at the start of work. He provided date of final inspection and I waited all day for the inspector to arrive—they never did. After that, I called the city multiple times regarding the permit for the now completed work, however they had no record of a permit application being approved, or even filed. Crew was present on my property for an average of 5-6 hours a day; I reported end times to SD rep every day via text message. Total hours present on property equaled 80.25 hours. SD is billing for 108.25 HR + some trips to Lowe’s, and is not willing, nor able to explain difference in hours worked or the added shopping charges (I had purchased all materials). At first, the invoice billed for dates when no work was performed, an “adjusted” invoice showed the same hours worked, only changing dates. I requested an explanation of the charges multiple times, however SD reps refused to provide an answer. The only explanation I was able to receive from SD’s secretary after I expressed that I do not understand how there can be such a difference between the billed hours and the hours actually worked, given that I had recorded start/end times, was that “customers are usually not present while they are working” (based on this statement, I assume I am not the first to be overcharged). After SD failed to provide explanation of charges and refused to adjust invoice, payment was submitted for 96 HR (less deposit) = 80.25 HR + 14 HR travel (14 days) + 1.75 HR for materials pick up (store pick up prepaid by me). This leaves an overcharge of 12.25 hours + Lowe’s charges that aren’t related to work performed on my property (I purchased and paid for all materials from Menards). The crew was also disrespectful to me and my property. One worker referred to my house as “three pigs home,” referring to myself, my daughter, and our dog. They also took things from my garage without permission. I have cameras in my garage, as well as the front and back of my house, and was present for much of the work, allowing me to experience their behavior. I submitted a complaint to the BBB on 09/19/21, however they closed the complaint after they failed to receive a response from SD. Shortly after, SD reps contacted me stating that I need to pay an additional $350 for them to finalize the permit with the city (~3 weeks after jobs end), and have since received an updated balance statement charging interest for the still unexplained charges."
