When you are prepared for the common delays and disruptions that can happen with a new home, you will be better able to deal with them. Assuming you have chosen a reputable builder, your best strategy is communication.
Most builders are committed to complete their customers' homes.
However, some of them fail to communicate that commitment. The unfortunate result is unhappy customers. Your builder should clearly explain after-sales service, repairs, and outstanding completions. In fact, this should be outlined in the contract. When you are told that some things must wait for warm, dry weather, don't be surprised if nothing happens on the first nice day.
