Sunrooms & Enclosures FAQs

How much does a custom sunroom cost?

The cost of a custom sunroom depends on the size, materials, roof style, glass package, and whether you choose a three-season or four-season sunroom. Because every home is different, we design each space around your layout, climate, and goals. 
 
At Great Day Improvements, we walk you through options clearly—so you understand exactly what you’re investing in. We also offer flexible financing plans to help make your sunroom project fit comfortably within your budget. 

What’s the difference between a three-season room and a four-season sunroom?

A three-season room is designed for spring, summer, and fall enjoyment, using energy-efficient glass and durable framing to protect against wind, rain, and pests.
A four-season sunroom is built for year-round comfort. It features advanced insulation, thermally engineered framing, and high-performance glass so you can enjoy natural light—even in colder months.
Our team will help you determine which option makes the most sense based on how you want to use your space and your regional climate.

What’s the difference between a screen room and sunroom?

In short, the difference is the material on the walls of your room. A sunroom has glass windows and doors while a screen room has only a screen material in the framing. A screen room allows the breeze to pass through without any of the bugs or yard debris. A sunroom allows sun into your room while blocking the breeze and, depending on how it’s built, can be heated or cooled.

Can I convert an existing covered patio, deck, or porch into a sunroom or enclosure?

Absolutely. Whether you would like to fully enclose your outdoor space or just add a screen system, we’ll custom design your room to meet your specific needs and fit the aesthetic of your home, all while following local building codes and your budget.

How long does sunroom installation take?

Eight to ten weeks is a normal estimation for a project, however, timelines vary based on design complexity, permitting, and weather conditions. After your consultation and finalized design, most sunroom installations are completed in a matter of weeks—not months..

Because we design, manufacture, and install our products through one accountable team, there are no confusing handoffs between vendors. That means clearer timelines, better communication, and a smoother overall experience.

Do sunrooms add value to your home?

Yes—professionally designed and installed sunrooms can increase usable living space, boost natural light, and enhance your home’s resale appeal. 
 
Beyond resale value, many homeowners see the greatest return in everyday living: more room for gatherings, quiet mornings with coffee, or a bright space to unwind. It’s not just an addition to your house—it’s an expansion of how you enjoy your home.

Are sunrooms energy efficient?

Absolutely. Our sunrooms are built with energy-efficient glass, insulated framing systems, and precision installation to help regulate indoor temperatures and reduce drafts. 
 
We manufacture a large portion of what we install, ensuring consistent quality and performance standards. That level of control helps us deliver long-lasting, high-performing spaces designed for comfort. 

Do I need a permit to build a sunroom?

In most areas, yes—permits are required for structural additions like sunrooms and enclosed patios. Requirements vary by municipality.
Our team handles the permitting process for you, ensuring your sunroom meets local building codes and zoning requirements. It’s part of our commitment to managing your project from start to finish—so you don’t have to navigate the red tape alone.

Can I start out with a screen room and later upgrade to a sunroom?

You bet. If your budget or lifestyle isn’t ready to commit to a fully enclosed glass sunroom, we can get you started with a screen room. When you’re ready, we can come back and easily swap your screens for single or double-paned insulated glass.

How do I get started with Great Day Improvements?

It starts with a free consultation where we listen to your needs, assess your space, and provide expert recommendations. From there, we create a custom plan that works for your home, your budget, and your timeline. Give us a call or fill out our contact form and we’ll schedule your free, in-home consultation at your convenience.
