When the time comes that you need to replace a basement window or windows in your home, the task is fairly simple to do. It is important that your windows are sealed tight so that they are waterproof and prevent drafts from coming into your home. Not only will the right windows bring style to your home, but they can also save you a lot of money on your electric bill and on other repairs, such as water damage. All you need to do is follow a few easy guidelines for simple and easy installation.

1. Check for Regulations

The first thing that you need to do is to check with the department in your area that handles the building regulations. It is important that you follow the guidelines of your area and adhere to the appropriate codes. Keep in mind that your basement window is also supposed to be able to provide you with a possible escape route in case of an emergency.

2. Remove Old Window

Your next step is going to be to remove the existing window to get the area ready for the new one. You first want to remove the trim from the exterior of the window and also pull out the nails. This same process should be repeated for the interior as well, and if, for some reason, the window does not come out easily, then you can use the flat bar on the top corners to pry it loose.

3. Repairs

Once you have the old window out, you will need to check for any damage, such as rotting wood. This will also give you an opportunity to check for any type of termite damage or other wear and tear that may have happened over the years. Make any necessary repairs before moving onto installing the new window.

4. New Window

Once all damage has been repaired, you will then place the new window from the outside into the frame. In order to have the window even, you may want to have someone stand on the inside of your home to help you line it up correctly. You want all gaps to be as close to the same as possible when you go to seal the window.

5. Attaching the Unit

To make sure the bottom of the window is level, nail one of the corners into the flange and then check with a carpenter’s level. Do not nail the other side until you know that the window is completely level before moving on.

6. Trim

Once the nailing is complete, you will then insert a weather resistant trim for the window on the exterior. You can use wood that has been treated, but for a better affect, you may want to use resin-based composite materials to a longer lasting effect.

7. Insulation and Wrap Up

Use fiberglass insulation in the gaps before placing trim. Do this from the inside to trap air. You can now install the interior trim, fill nail holes, caulk and paint.
