Frequently Asked Questions
Top 5 Questions Our Customers Ask Before Building a Sunroom
How much does a sunroom cost?
Sunroom pricing depends on size, style, and selected features, with most projects ranging from $25,000 to $60,000+. We provide free on-site consultations and custom design estimates tailored to your home.
Do I need a building permit?
Yes, most sunroom additions require a permit. As a Class A licensed contractor, ModExt handles the entire permitting process for you, ensuring your build meets all local codes and inspection requirements.
What’s the difference between a 3-season and a 4-season sunroom?
A 3-season sunroom is great for spring through fall and uses screen or vinyl windows without HVAC. A 4-season sunroom is fully insulated, climate-controlled, and built for year-round comfort—including heating, cooling, and energy-efficient glass. We’ll help you choose what fits your lifestyle best.
Can the sunroom match my home’s look?
Absolutely! We design custom sunrooms that blend with your home’s roofline, siding, and overall style—seamlessly.
How long does Sunroom Construction take?
Timelines depend on the type of sunroom (prefab vs. custom stick-built), permitting, and material availability. On average, projects take 8-10 weeks from final design approval. ModExt keeps you informed at every step.
