"I had an addition I wanted for our home. We were required to have a survey and an engineer drawing to apply for the permit. I had a list of 10-15 local engineering companies given to me by the permitting office. Very few would return my call. several the rest said they only do commercial or that this was too small of a job and would cost more. It was taking months and I was frustrated and decided to try Angie’s. I am so pleased. I had a response that very day I inquired for the job. It was clear what was needed from me. Great communication and answered questions to help me get them what they needed. The project from start to finish was drafted within 3 weeks. It could have been done sooner but I was traveling and not able to check emails. Once I told them to text me to alert me of an email they did that. I would highly recommend them."
