Insert and full-frame replacement are different scopes
Confirm whether the existing frame remains, how the opening is prepared, and what interior/exterior trim and flashing work is included.
Use exact product specifications
Compare manufacturer, series, operation, glass package, safety/egress requirements, colors, hardware, screens, and energy ratings.
Plan for hidden-condition rules
Ask how rot or damaged framing is documented and priced if discovered after removal.
Use the decision as the starting baseline
When you choose a contractor, preserve the accepted scope, price, allowances, and payment milestones. CheckMyBids is the pre-hire side of the workflow; CheckMyRemodel is where the awarded project continues when changes and payments start.
