Of course. You are spending a lot of money and if multiple bids increase your comfort level then you should ask for a couple. Putting a bid together is a time intensive process and so I always advise that you don’t get more than three. One problem with construction bids is that there isn’t a consistent price strategy. You can get three bids for one job and get three different costs presented in three different ways. In the end I would ask myself who do I want to call on Saturday morning because I have a construction related problem? Who do I want to see day in and day out while the project is going on? Who is going to communicate with me about the need for a change order?
