Wood Home Window Sashes | Window Sash Measuring Info | All Brands

At this time, all sash reproduction work is temporarily on hold due to ongoing supply‑chain disruptions affecting several of the mill‑work components we rely on. We anticipate a delay of approximately 60-90 days while our suppliers stabilize availability. During this period, certain sash profiles or related materials may not be offered exactly as they have been over the past 7–8 years. We appreciate your patience and will resume normal production as soon as conditions allow.

Step 1: Measuring the Width of the Window - the top, middle, and bottom to ensure all measurements; Remove any jamb liners temporarily to avoid any pulleys, weather-strips, or stops in the window frame. Record the measurements.

Step 1(A) Measuring the Width and Height of --- THE INSIDE VISIBLE GLASS of the Window - the top, middle, and bottom IVG; HEIGHT AND WIDTH INSIDE ( see drawing ) Record the measurements.

Step 1(B) Measuring the OVERALL WIDTH, HEIGHT and DEPTH - Width, Height and DEPTH of the actual "wood" SASH FRAME that makes of window: Measure outside top, middle, and bottom, HEIGHT T, M, B .. the DEPTH OR THICKNESS OF FRAMES to ensure all fit and measurements. Record the measurements.

Step 2: Measuring the Height of the Window - Open both sashes slightly and place the tape measure between the sashes. Start at the top, measure from the head jamb to the foot of the sill on the window. Make sure to eliminate any stops within the window that might obstruct a precise measurement. Start at the sill, and measure to the top of the sloped sill on the exterior side of the lower sash. Measure the height at the left, middle, and right sides of the entire window. Record the measurements you have taken with the pencil and paper.

Step 3: Measuring the Angles of the Window - You will want to confirm that the existing window is square by measuring both diagonals on the window. If the measurements are more than ¼” out of proportion, then an out of square adjustment in the width of the measured window must be made. To determine the adjustment, a plumb line is made from each corner to the sill or head of the window using a level. Use a plumb line that falls within the opening of the window, measure the out of square adjustment. Subtract this measurement from the smallest width measurement. Record this width measurement as the smallest width adjustment measurement with the paper and pencil.

BEST OPTIONAL METHOD: As we always say: "Nothing is better than a sample"- so many homeowners cannot answer these questions? 

Obtaining Correct Measurements for Replacement Wood Window Sashes is only "one part" of the equation process. Here are some other considerations that must be determined: Brand of Windows? Cladding Type? - "extruded aluminum" or "roll-formed clad" .. Can Cladding be "removed and reset" to new sashes? How many units are needed? .. Sizes and Shapes?
