Residential windows & doors

Why should you install new windows & doors? A study conducted by the U.S. Department of Energy found that inefficient windows & doors are accountable for nearly 30% of energy loss in residential homes. Are your windows & doors responsible for 1/3 of your monthly energy bill? If your windows & doors are more than a decade old or if you have single-pane windows they might be.

Commercial windows & doors

Why do so many Southwest Florida building owners, contractors, architects, and property managers go with AGT Builders for their window & door needs? At AGT Builders, we have the ability to deliver quality service to every window & door project we take on, regardless of scope

If you’re looking for something completely tailored to you, we can design and build a one-off, custom designed window. Since 2006, we’ve delivered the perfect combination of thoughtful design and robust construction, AGT is known for our uncommon capacity to recognize and transform a client’s wants into an elegantly functional, comfortable, and inviting design.


Choosing experienced installers like the team at AGT is a critical part of your window or door project.

"The construction industry has always been a very volatile market with exhausting, yet rewarding highs as well as devastating lows that often separate the highest performers within in our industry. With higher expectations, shorter time tables and longer lead times, we often forget the people that perform the tasks we are asking of them in order to inch towards the common goal of delivering a home. At the end of the day, people do business with people and our past experiences combined with our perception is how we enter into these Subcontractor relationships. In the case of AGT, perception is reality. They embody true honesty and integrity in a field that is not particularly known for setting the bar in values. They are a husband and wife company who are actively involved in their business while working tirelessly to retain long-term employees by empowering them to make the right decisions on behalf of the company and their customers. They are true professionals of their trade and are the definition of a Trade Partner" in this business."
