How to Remove Pella Window Sashes: A Step-by-Step Guide for Commercial Buildings Today

Pella commercial windows are prized for their durability, energy efficiency, and sleek design, making them a top choice for many commercial buildings. However, like any windows, they may need maintenance or replacement over time. One common task is removing the window sashes. Whether for cleaning, repair, or replacement, understanding how to properly remove Pella commercial window sashes is essential. This guide will walk you through the process to ensure a smooth and safe removal.

Tools You’ll Need:

Before starting, gather the necessary tools:

• Flathead screwdriver

• Phillips head screwdriver

• Utility knife

• Gloves

• Safety glasses

Step-by-Step Instructions

1. Preparation

   – Safety First: Wear gloves and safety glasses to protect yourself from any broken glass or sharp edges.

   – Clear the Area: Ensure the area around the window is clear of any obstructions, such as office furniture or equipment.

2. Unlock and Open the Window

   – Ensure the window is unlocked. For commercial double-hung windows, raise the lower sash approximately 4-6 inches.

3. Remove the Interior Stop (for Double-Hung Windows)

   – Locate the interior stop, a small strip of wood or vinyl on the interior side of the window. Use a flathead screwdriver to carefully pry it away from the frame. Be gentle to avoid damaging the stop, as you will need to reinstall it later.

4. Detach the Sash Cord or Balance System

Older Models: If your Pella commercial windows have sash cords, cut the cords using a utility knife. Ensure you support the window sash while doing this.

Newer Models: Pella’s more recent commercial windows often feature a balance system. Locate the balance shoes on either side of the sash. Use a Phillips head screwdriver to detach the balance shoes from the sash.

5. Tilt the Sash and Remove

   – With the cords or balance system detached, you can now tilt the sash inward. Raise the sash to a 90-degree angle from the window frame. Carefully lift one side of the sash to disengage it from the pivot pins, then lift out the entire sash.

6. Remove the Exterior Sash (for Double-Hung Windows)

   – Lower the upper sash about 4-6 inches, repeating the process of removing the interior stop if necessary. Follow the same steps to detach the sash cord or balance system, then tilt and remove the sash.

7. For Casement Windows

   – Open the Window Fully: Use the crank handle to open the casement window fully.

   – Release the Hinge Arm: Locate the hinge arm at the top and bottom of the sash. Use a screwdriver to release the arm by removing the screws or clips.

   – Remove the Sash: Once the hinge arms are detached, you can lift the sash away from the frame.

8. Clean and Store the Sashes

   – If you plan to reinstall the sashes, clean them thoroughly and store them in a safe place to avoid damage.

Tips and Warnings

• Handle with Care: Window sashes can be heavy and fragile. Always support the sash properly to avoid dropping and breaking it.

• Replacement: If you’re replacing the sashes, ensure you have the correct replacement parts. Pella offers specific replacement kits for different window models.

• Consult the Manual: Refer to your Pella window manual for model-specific instructions. If you don’t have the manual, you can often find it online.
