At The Real Seal Basement Waterproofing and Foundation Repair, we provide basement window installation for Egress windows or basement sliding escape windows that serve as escape routes out of your house in the event of an emergency. They are commonly found in below-ground basements. Like insurance policies, security alarms, and plungers, egress windows are something you hope you never have to use—but you’ll be glad you have them if the situation ever arises. That’s why The Real Seal LLC offers Chicago-area basement window installation and replacement services for homes.
Benefits of Egress Windows
In addition to increased safety, egress windows also provide several other benefits to you and your home. Basement egress windows let sunlight into your basement, increasing natural light and improving the space as a whole. Egress windows are also available in a variety of styles, including sliding windows, which can add a touch of style to your basement. And because most homes require egress windows in basements, these windows can also increase your home’s value.
Enhanced Safety and Emergency Escape
Egress windows can be a secondary means of escape for you and your family during a fire or other urgent situations. These windows can also be used by first responders, such as firefighters, police officers, and paramedics, to enter your home during an emergency.
Natural Light
By installing an egress window, you can allow natural light into a dark basement. This helps you create a brighter environment, reducing the need for artificial lighting. In general, egress windows are designed to be large enough to enter and exit through, which allows more light to enter your basement.
Improved Ventilation
Our team installs high-quality egress windows that allow better airflow throughout the basement if you open them. This improved ventilation helps you prevent musty, damp smells and mold and mildew growth.
High Property Value
Egress windows add functional value and boost your home’s market value. By installing egress windows, you can convert rooms in your home’s basement into an additional bedroom, storage space, living area, or entertainment room.
Egress Window Requirements in Chicago, IL
The International Residential Code (IRC) sets the building requirements for one- and two-family homes up to three stories tall. In addition, local counties have their building codes that should be verified before window installation. In Illinois, the IRC requires that basement egress windows have a minimum opening of 5.7 square feet above grade and 5 square feet below grade, a minimum width of 20 inches, and a minimum height of 24 inches. When you choose The Real Seal LLC for your Chicago-area egress window installation or replacement services, you can rest assured that your egress windows will be up to code.
The Real Seal’s Egress Window Installation Process
Our comprehensive egress window installation process includes the following steps:
Step 1: Site Preparation
We start our egress window installation process with a thorough site preparation. Our team assesses your basement’s layout to finalize the best location to install the window. We make sure to meet all local building codes and safety requirements while installing egress windows.
Step 2: Excavation
During the excavation process, we dig outside the basement where the egress window will be installed. Our professional team carefully measures the depth and width of the area we excavate based on the window size, allowing space for the necessary drainage system.
Step 3: Concrete Cutting and Window Installation
Our team uses industry-best technologies and standard techniques to cut into the basement wall to create an opening for the egress window. We cut into the concrete carefully, making sure we don’t compromise the structural integrity of your foundation. Then, we carefully install an egress window to provide you with an emergency entrance or exit and prevent any leaks or gaps around the window.
