Replacement windows.

Step 1- Thorough Inspection:

The first thing that needs to happen is a complete evaluation of the current problems that you, the homeowner, are trying to solve with your new replacement windows. Are you trying to eliminate drafts or leaks? Do you want to reduce your energy bills? Are you looking for a simple cosmetic replacement? Etc.


It is important that you and the company that you hire to replace your windows are both on the same page as to what you want to accomplish with your new replacement windows. You want to avoid the all-too-common pitfall of a homeowner spending thousands of dollars on replacement windows, only to end up with the exact same problem that they had before replacing the windows.

The fact of the matter is that you may not even need new windows!


A thorough inspection will reveal the true cause of the problem that you are trying to fix.


Once a thorough examination has been completed, then it’s time to move to the next logical step.



Now that you and the company that you are considering for your replacement windows have a complete understanding of exactly what needs to be accomplished, you can start discussing options.

It is imperative to understand that there really isn’t a “best window.” The reason for this is that all reputable window manufacturers have a long-standing record of quality production. They all have warranties on their product. And they all have windows certified through AAMA (American Architectural Manufacturers Association— the original third-party window performance program that has provided manufacturers with the means to independently demonstrate product performance to their customers). A window that has AAMA certification will perform as stated. 

However, a critical component to consider is the proper installation of the windows. The most expensive window in the market place, if not installed properly, will fail prematurely. 

At Guardian, we take the time to thoroughly cover all of the options available to you that is guaranteed to fix the problem that you are wanting addressed with the new replacement windows. We represent all of the major manufacturers so we simply guide you through the process of choosing the correct windows for your home that fixes your problems and fits within your budget. 

You are in control of choosing the exact options that you want for your home. With us as a resource, we help you to design and build your project. 


We understand that typical homeowners aren’t window replacement experts. Additionally, we know that it is almost impossible to find reliable information about what homeowners need to know when buying replacement windows. 

At Guardian, we take the time to thoroughly answer any and all questions that you may have regarding your current situation, what is happening, why it’s happening, and what needs to be done to fix the problem. Options will be presented to you along with an explanation of how the combination of options address the main concerns that you want fixed with your new replacement windows. 

More importantly, we take the time to provide you with important information regarding your rights as a homeowner in Wisconsin. 

First and foremost, the people who work at Guardian are homeowners. We are simply doing the right thing in ensuring that you understand your rights. We know that helping you to understand your rights will provide you with the most protection possible against unscrupulous contractors. After all, if we were in your shoes, that’s what we would want. 


Now it’s time to confirm the choices that you’ve made for your home. Because of the previous steps, you are now significantly more educated and informed about your specific needs and goals. This clear understanding allows us to have a comfortable, respectful, non-confrontational, and intelligent conversation about the possible solutions for your home. 

You can then take the proposal along with all other paperwork and review it at your leisure. The price is the price and there is no special price that’s “only good for today.” You can ask more questions, discuss different options, and continue to become intimately familiar with every piece of information presented to you so that you gain the comfort and trust needed to know that you are making the right decision for you and your family. 


We have formed strategic partnerships with several trusted financial institutions to provide direct & personalized access to a variety of payment and finance options. We will show you what those options are so that you can make the decision that's best for you.

We Have the Largest Product Selection Available

Limited Selection is The Main Cause of Confusion Among Homeowners.

Receiving conflicting information from the sales representatives of 2 competing window replacement companies representing competing product lines is often the norm. No matter how hard you try, you can’t get a straight answer from any sales representative because their answers are skewed to sell their products. One sales rep will tell you that product ‘A’ is inferior to their product (product ‘B’) and visa-versa..


At Guardian Exteriors, not only do we offer all of the major product lines that are available in the marketplace today, but we also have relationships with the largest wholesale – factory direct manufacturers who can have your windows custom built with the exact features you want and none that you don’t.


At Guardian, we can honestly say that we can properly guide you through the selection process so that you end up with the correct replacement windows that fill your specific needs and your current budget.
