Do they visit before quoting
A phone price cannot account for out-of-square openings, sun direction or mounting surfaces. A company that visits is quoting the real job.
Ask what they will measure and whether you will receive a written proposal.
How do they measure
Careful installers measure each opening in several places and note levels and clearances. Quick, single measurements lead to gaps and binding.
Ask how they handle openings that are not square.
What fabrics and brands do they offer
Ask for samples in your light and for the maker of the motor and fabric. Established brands mean parts and service stay available.
Ask how long they have worked with the products they offer.
What does the proposal include
A proposal should list sizes, fabric, motors, controls, mounting, electrical coordination, installation and cleanup, plus exclusions.
Ask how changes and surprises are handled.
Service after installation
Screens have moving parts. Ask who services them, how quickly and whether they work on other brands.
A local company with a service plan is a good sign.
References and verification
Ask for recent customers you can call, look at photos and reviews and check your local requirements yourself.
Confirm business details and any credentials your city requires.
Choose the company that visits first, measures carefully and writes the whole scope down.
