Many homeowners don’t pay attention to their basement windows which is a shame. Why? Because your basement windows play a key role in keeping energy costs low, facilitating proper ventilation and protecting your home from mold and moisture.  

We’ll tell you how to determine when to replace basement windows and demonstrate how replacing your basement windows can benefit you as a homeowner. Whether you’re trying to save money on your energy bill, keep your house looking in good condition, protect your home from moisture, or all of the above — this blog is for you.

Moisture leads to mold which represents a serious and potentially expensive threat to any home. Basements are notorious for accumulating moisture. When basement windows are cracked or have broken seals, moisture comes in which means mold will follow. 

Likewise, the same cracks and broken seals in basement windows that let moisture in also let heat out, which drives up your energy bill.

Types of Basement Windows

Before diving into the advantages of replacing your basement windows, let’s take a look at some of the most common types of basement windows, along with the pros and cons associated with each type of basement window.  

Hopper Windows

Pros: Hopper windows are arguably the most common basement windows around. These windows are essentially inverted awning windows but reversed. These windows hinge at the bottom and open at the top, opening towards the inside of your home rather than towards the outside. 

Cons: Unfortunately, hopper windows allow a great deal of rain and snow to get into the home which can lead to excessive moisture and mold. 

Awning Windows

Pros: Awning windows prevent rain and snow from leaking into your basement which helps protect your home against mold. 

Cons: One of the disadvantages to having awning windows is the fact that they’re difficult to install along walkways and patios.

Horizontal Sliding Windows

Pros: Horizontal sliding windows are ideal for walkout basements that are above ground.  

Cons: Horizontal sliding windows can be more expensive; however, many homeowners find that the convenience is worth the investment. 

Fixed Windows

Pros: Fixed windows are preferred by countless homeowners for their ability to maximize natural light. Natural light is an especially important factor when it comes to basements which typically feature poor lighting. The natural light they provide can help make basements seem larger and make it easier to see outside.

Cons: While fixed windows are prized for the natural light they bring in, they tend to be significantly larger than hopper, awning and slider windows. 

Double-Hung Windows

Pros: Although they’re not generally found in basements, double-hung windows are favored for air and temperature control. 

Cons: Double-hung windows are best suited for basements that are fully above ground because they tend to look rather awkward on homes with basements that are partially above ground.

Casement Windows

Pros: Casement windows are a great option for above-ground basements. You can open and close them with a hand crank. If security is a concern, you’ll be glad to hear that casement windows are equipped with locks. 

Cons: They protrude outwards and are taller than they are wide, which can be a complication with window wells.

The Top Advantages to Replacing Your Basement Windows

If your basement windows are well-insulated and in good shape other than needing a fresh coat of paint, you needn’t trouble yourself with having them replaced. However, if they are damaged or old, it may be time for a replacement.

Here are six compelling advantages to having your basement windows replaced. 

Get Rid of Any Gaps to Stop Air Infiltration

If the windows in your basement are old, you’ll probably find that they’re riddled with gaps and cracks around the window glass and frame. Gaps waste enormous amounts of energy which costs money and makes it difficult to regulate the temperature within your basement. 

Cracks and gaps around your basement window allow heat to escape during the colder months and come in during the warmer months. Put an end to air infiltration with basement window replacement and installation. 

The Advantages of Properly Insulated Basement Windows

You can protect your house from bad weather and harsh temperatures by replacing your basement windows to improve insulation. New basement windows come with thicker insulated glass which is more effective at combating and preventing heat loss. 

Basement windows that are well-insulated also help keep out irritating noises from the street. 

Boost Energy Efficiency and Lower Your Energy Bill

Not only do well-insulated basement windows keep heat in, but they also keep costs down. By keeping all of that heat in, you’ll save bundles of money on your energy bill. One of the most common mistakes people make when trying to reduce their heating expenses is to focus on replacing all of the upstairs windows with new ones that are more energy-efficient while neglecting to replace their basement windows.

Spending money on energy-efficient upgrades doesn’t do much good unless you replace your basement windows too. 

New Basement Windows Keep Moisture Out 

In addition to letting heat escape, cracked basement windows also let moisture in which can lead to expensive problems with mold. When the seal on a basement window becomes compromised, it lets moisture seep into the home.

If that moisture is left unchecked, it can lead to an aggressive growth of toxic mold that can damage your belongings. These problems can easily be avoided by having any basement windows with cracks in them replaced. 

Strengthen Your Home’s Security

Ground-level basement windows are a popular entry point for burglars and intruders. Most intruders will try to enter a home through the basement windows first before trying something else. By investing in basement windows that are durable and secure, you’re investing in safety.

Improve the Airflow in Your Basement

For those of you that use your basement as a workshop, home gym or a place to store paint cans and cleaning products, you’ll want to invest in new windows to make sure your basement has proper airflow. 

Without proper airflow, basements pose a huge risk for fume build-ups that can be hazardous to your health. Likewise, basements lacking adequate airflow tend to lock in foul odors. You can improve airflow by investing in new basement windows that are easy to open. 

Hire a Reliable Basement Window Repair or Replacement Specialist

If you’ve done all the research, tried to fix things yourself and there is still a problem with your basement window, there’s no shame in hiring a professional. This can be an arduous process for many as there can be a lot to navigate when it comes to replacing or repairing your basement window.
