In this blog post, I'll take you through the process of installing windows in my house. If you're considering a window installation project, this guide will help you understand the steps involved and the products you might need.

Preparation and Material Selection:

I begin by installing all the windows in my house, except for the two on the side of the garage. I want to emphasize the importance of using high-quality materials for a long-lasting and weather-resistant window installation. I introduce a flexible window wrap product from MFM Building Products, which I'm using for creating sills.

Sill Installation: The installation starts with the sills. It's important to set the sills at a slight angle (approximately three degrees) to ensure proper water drainage. This is done to prevent any water intrusion and potential window failure over time. I apply the flexible window wrap to create the sill, ensuring a watertight seal.

Applying the Flexible Window Wrap: The flexible window wrap is an adhesive product that can be easily applied. I peel off the paper backing and apply the wrap, making sure to leave about four to six inches overlapping the edge. This overlapping design prevents water from seeping into the structure.

Using a Roller for Application: To ensure a secure seal, I use a roller to press down the flexible window wrap. This step ensures proper adhesion and prevents any potential water infiltration.

Addressing Corners: One interesting feature of the flexible window wrap is its ability to adapt to corners without the need for cutting. I demonstrate how you can simply push the material around the corners, making the installation easier and more effective.

Securing the Window: Once the wrap is applied, the window is secured in place. I use screws to attach it to the structure, ensuring a tight fit. The flexible window wrap is designed with a rough surface to allow water to escape through small channels in case of window failure, preventing damage.

House wrap and window tape

House Wrap and Window Tape: After securing the window, I pull the house wrap down over the window flange, and I use window tape to seal the sides and the top. This additional layer of protection ensures that the window is completely sealed and protected from the elements.

Completing the Installation: I proceed to install the remaining windows in my house, ensuring that I follow each step meticulously. I should mention that I have two windows above the garage that I'll install once the garage is ready.

By following these steps and using the recommended materials, you can ensure a successful and durable window installation in your home.
