Size and number of openings
Every opening is priced by its width and height, and a patio with three open sides costs more than one with a single side. Larger screens use bigger housings, stronger tracks and heavier motors.
Ask every company to list each opening and its size so you can compare like with like.
Fabric
Insect mesh, solar weave, privacy cloth and clear vinyl differ in cost and in performance. Specialty fabrics and heavy-duty mesh can cost more than standard mesh.
Choose the fabric that solves your real problem, not only the lowest price.
Motors and controls
A basic motor with a remote costs less than a system with wall keypads, sensors and smart-home links. Each added control brings useful features and added cost.
Decide early which controls you will actually use.
Mounting and structure
Solid beams make mounting simple. Thin beams, brick columns and unusual openings may need headers, brackets or special anchors.
A good proposal states the mounting it assumes.
Electrical work
Motors need power. Running new wiring, adding a circuit or choosing a battery system affects cost and schedule.
Qualified electricians handle line-voltage work, and it should be listed in the proposal.
How to compare quotes
Compare scopes, not totals: sizes, fabric, motors, controls, mounting, electrical, installation and cleanup.
A clear, itemized proposal is a sign of an organized company.
Compare written scopes, decide on fabric and controls first and plan the mounting and power so there are no surprises.
