What to ask about in a quote
- Layout and proposed connections
- Utility and comfort work
- Wall and floor preparation
- Agency, design, and inspection responsibilities
Common questions
Is an attached garage always less expensive?
No. Existing conditions, utility capacity, and the proposed scope can change the comparison. Obtain estimates for the actual property.
What should an attached-garage quote explain?
Ask how the new room connects to the house and whether the proposal includes changes to the shared wall, flooring transitions, electrical work, and any interior repairs.
Can the existing home systems be used?
That depends on the systems and proposed load. Ask qualified trades to assess the existing equipment and identify any changes in the written scope.
