What Does a Window Professional Do?


Whether you’re building a new home, remodeling an old one or just replacing a few windows that are past their prime, your Ontario, CA window professional will help you pick the right windows for your needs, home style and budget. Windows come in so many sizes and types that expert advice often is invaluable in helping you make the best decision. These pros also are knowledgeable about sliding doors, French doors and other paned portals.

Window professionals also can repair a window that’s developed problems or fix a broken sheet of glass. Your window pro might work closely with California builders or remodelers as well.

Questions to ask a prospective window professional:


  • How long have you been in the business?
  • How many projects like mine have you completed?
  • May I see examples of previous projects?
  • Who will be working on the project? Are the workers employees or subcontractors?
  • What training and licensing do you have?
  • Can you provide me with references?
  • How do you charge, and what does that include?
  • Can you give me a written estimate?
  • Do you offer a warranty?
  • When can this job get done?
  • What happens when the cost exceeds the budget? What about changes to materials or labor pricing?
  • What will I need to provide?
  • Are there any important considerations or concerns you foresee with this project?
