How a Consumer Hired a Lawyer to Draft a Plumbing Contract in Colorado

Speaking very generally, the answer will depend on the wording of the contract itself, and just what you agreed to. However, it's common for this type of contract to include provisions for a work change order. Look to see if your contract includes a reference to something like a "change order" - this is usually how the reference to the formal document used to modify the original contract is call - typically for: Additional work, Changes in scope or materials, Adjustments to cost or timeline. It must be agreed to and signed by both parties (typically the contractor and homeowner or project owner) before the change is performed, unless the contract provides otherwise. The key is whether or not your contract provides otherwise. Sometimes contracts allow for extra time/materials that a contractor may find once walls are opened and whether hidden defects and problems can be seen. Your plumber should explain to you the reasons for the extra charges. I hope that's been helpful. Don't forget you can find a residential contruction contract attorney through ContractsCounsel.com to review the contract and negotiate with the plumber on your behalf. (I do not do this kind of work myself right now).
