Signs That You Need New Windows for Your Basement

Operating Difficulty

One of the ways you can determine whether you need a replacement is by checking the window's functionality. Whatever type you may have, window features must be working correctly. Hence, you should check whether you can open them with ease or not. Besides that, you should check if you can lock the window or not. Sometimes the parts can jam or get stuck from corrosion. You should also look for other defects of window components. For example, look for rust, rot, and other problems.

Moisture Accumulation

If you have a double-paned basement window, then you must know how to check for moisture. The glass is typically filled with gas to ensure that air doesn't accumulate. As a result, the window can stay clear, and you can have a perfect view of the outside. However, sometimes due to condensation, the gas can displace and make your house vulnerable. That is because moisture can accumulate around the basement windows.

Not only that, but the weather seal also becomes damaged. Thus, water from rain can seep into your basement. You can check for moisture around the fixture and hinges of the windows. The best way to identify damage is by looking for discoloration, paint coming off, and mold. Mold appears slimy in texture and typically green or black in color.

Damaged Glass

Some basement windows can never open. That is why most people install these in the basement for additional security. However, these are only best at protecting if they are intact. Otherwise, they will offer easy access to intruders. To see if the windows of your basement require replacement, you should look for damage. Even a minor crack can decrease their efficiency. That is because air loss can take place, and so your home temperature will not be maintained. As a result, your energy bills will increase.

Besides that, a crack can allow rain or snow to enter your house during winters. Not only that, but it can make it easy for intruders to sneak into your place without making too much noise.

Window Well Loosening

Window wells are what keeps the windows secure and in place. They are the reason why your windows stay attached to the surface. If you spot warping of wells, then it's time for you to replace the windows.

You can get the wells repaired too if you don't want to spend more. But keep in mind that the issue is more likely to occur again due to the aging of the window. That is why it is best to replace all of them if the wells start to loosen.

If you let the issue, be, then you'll be opening your home to further risk. That is because it will affect the drainage system. Not only that but even animals and intruders can break in with ease.

Besides, that most of them have different operational methods. That is why it is best to get the one that is easy for you. Here are the top types of basement windows you can get:

Slider Version

These are the most prevalent windows you’ll find in most houses. They have two different sections. One of them remains in place and does not open. Meanwhile, you can slide the other part in one direction to open and in the opposite way to close it.

Besides that, they allow light to enter the room during the day. An example of fixed types is Glass Block windows. This type also offers greater security than the sliding version. That is because they are more difficult to tamper using a crowbar.

Hopper Version

Hopper Basement windows are one of the standard versions you can find in various homes. They are pretty popular and for a good reason. Firstly, they ventilate your basement excellently. Secondly, they come in a variety of models with different privacy features. For example, you can choose a version that will not allow anyone from the outside to peak in.

Crank Version

Crank windows are also called casement windows. These are mainly designed for above-ground basements. That is why they should be your top replacement choice if you have such a basement. These windows have a panel and can open due to vertical hinges like a door. They have a crank handle that you can use to open them. However, keep in mind if you're looking for high security, this type may not be the best.

Double Hung Version

These windows consist of two components that can slide independently in either direction. You can get either the vertically opening version or the horizontally one. They can provide adequate ventilation and light whenever you need it. However, these windows are typically high. That is why they are not suitable for most basements. Hence, they should not be your first choice, no matter how cheap you get them.

What are the Best Materials for Basement Windows?

Just like different types, all products are also made of different materials. That is why you must know the best ones. Otherwise, you may end up replacing your basement windows with worse options. Here are the best materials that you should consider:

  • Fiberglass - If you're looking for windows that will secure your basement for years, then you should opt for fiberglass material. It is highly durable and water-resistant as well. Thus, the windows won't warp, rust, and crack, making them a secure option.
  • Wood - Wood is one of the classy materials and is best for aesthetics reasons. In most versions, it is used for lining the interior of the window. However, you can find options that are purely made from wood as well. This material is excellent for insulation but keep in mind that it can degrade quickly.
  • Clad-Wood - This is a better alternative for windows made out of wood. The interior is lined with wood cladding. Meanwhile, the exterior is made of aluminum, making the window highly durable. What sets this material apart from pure wood is that this is resistant to rot.

How to Secure your Basement Windows?

Many basement window types are difficult to tamper with. However, that does not mean they are fully secure. That is why you must take additional steps to improve the security of your home. Here are some of the cost-effective options you can benefit from:

  • Increase the Lights. Lights are one of the ways to keep intruders out as they compromise the invisibility of the individuals.

  • Put Bars on the Window. One of the best ways to protect your home from vulnerable access points is by having window bars installed. With them in place, no one will dare to enter your home.
