Consultation & Project Evaluation

Every project begins with a conversation.

We evaluate your current windows or doors and discuss your goals for the project. During this visit we assess:

  • Window or door condition
  • Energy efficiency concerns
  • Operation issues (sticking, drafts, fogging)
  • Design and style preferences

This helps determine whether glass replacement, insert replacement, or full-frame replacement is the best solution.

Design & Product Selection& Project Evaluation

Next, we help you choose the right window or door style for your home.

Because SJI Glass, Windows & Doors works with many manufacturers, we can recommend products that best match your needs rather than being limited to a single brand. During this stage we review:

  • Window and door styles
  • Glass options and energy performance
  • Frame materials
  • Hardware finishes
  • Color and design options

Our goal is to help you find the right balance of performance, appearance, and budget.

Precision Measurements

Accurate measurements are essential for a successful installation.

We carefully measure each opening to ensure the new windows or doors fit correctly within the structure of your home.

Every unit is then ordered to match the exact specifications of your openings.

Installation Planning

Once your windows or doors are ready, we schedule the installation and provide guidance on
preparing your home. You may be asked to:

  • Clear access to the work area or let us know if you’d like our assistance for that
  • Ensure access to the exterior work area

Our goal is to protect your home and keep the installation process efficient.

Proper installation ensures your windows and doors perform as intended for energy efficiency,
