The Importance of Accurate Measurements

Accurate measurements are essential when replacing windows for several reasons: 

  • Proper Fit: Precise measurements ensure that the new windows fit perfectly into the existing window openings, creating a secure and airtight seal. 
  • Energy Efficiency: A well-fitted window helps to maintain the home’s energy efficiency by preventing drafts and reducing heat transfer. This can result in lower energy bills and a more comfortable living environment. 
  • Aesthetic Appeal: Accurate measurements help to ensure a clean and polished appearance, enhancing the overall aesthetic of the home. 
  • Cost Efficiency: Precise measurements help to avoid costly mistakes, such as ordering windows that are too large or too small for the openings, which may result in additional expenses for adjustments or replacements. 


Key Measurements to Consider

When measuring windows for replacement, professionals focus on several key dimensions: 

  • Width: The width of the window opening is measured from the inside of the jamb on one side to the inside of the jamb on the other side. This measurement should be taken at the top, middle, and bottom of the opening to account for any discrepancies. The smallest measurement is typically used when ordering replacement windows. 
  • Height: The height of the window opening is measured from the top of the sill to the bottom of the head jamb. Similar to the width, this measurement should be taken on the left, center, and right sides of the opening, with the smallest measurement being used for the order. 
  • Squareness: To ensure that the window opening is square, professionals measure the diagonals from one corner to the opposite corner. If the diagonal measurements are equal or within 1/8 inch of each other, the opening is considered square. If the measurements differ by more than 1/8 inch, adjustments may need to be made to the opening. 
  • Depth: The depth of the window opening is measured from the inside of the window frame to the outside of the window frame. This measurement is essential for determining the appropriate depth of the replacement window.replacement windows in El Cajon, CA

When measuring windows for replacement, professionals at Pelican Replacement Windows follow a systematic process to ensure accuracy: 

  • Inspection: The window opening is thoroughly inspected for any signs of damage or irregularities that may affect the measurements or installation process. 
  • Measurement: Using a high-quality measuring tape, the professional takes multiple measurements of the width, height, and depth of the window opening, as well as checks for squareness. 
  • Documentation: The measurements are recorded clearly and organized, ensuring that the replacement windows are ordered to the correct specifications. 
  • Double-Checking: To minimize the risk of errors, professionals double-check their measurements before finalizing the order.
