Plan the window or door project
Start by listing the openings involved and what you want to change: the window or door style, the look of the home, or the level of hurricane protection you are considering. Photos and rough opening measurements can help you organize questions, but measurements should be confirmed before any product is ordered. If the project includes several openings, note which ones are highest priority so you can compare options consistently.
Compare product choices
For each opening, consider how the product will be used, the appearance you want and your budget. French doors and impact-resistant glass are among the product options. Ask for the product specifications and any applicable installation details so you can compare choices on more than appearance alone. For hurricane protection, distinguish the protection features of a product from other project requirements that may apply to your home.
Clarify scope and payment
Before committing to a purchase, write down which windows or doors are included and what work you expect. Request a clear explanation of the product selection, installation scope and any costs or financing terms relevant to your project. Financing and several payment methods are available, but available terms can vary; confirm the current details directly when discussing an order.
