What will it cost and will the price change?

99% of our jobs are done on a fixed price basis with a written contract containing a detailed description of the work, payment terms, construction drawings (when necessary) and other terms and conditions. The price will only increase if we encounter existing hidden conditions or damage, or if the customer wants to make changes or have additional work done. Like our contracts, most of our changes are done with a written fixed price change order, approved in advance of the work being done.
