A sunroom can turn a hot, buggy screen porch into a room you use all year. But what does it really cost?
Most of our sunroom projects in Raleigh and the Triangle cost between $6,000 and $40,000. Where yours lands depends on the type of room, the size, and what is already there.
Sunroom Costs by Type
| Room Type | Where It Falls | When You Can Use It |
|---|---|---|
| EzeBreeze screen room conversion | Lower end | Spring through fall. Panels open for a breeze. |
| Three-season room | Middle | Most of the year, minus the coldest weeks |
| Four-season (heated) sunroom | Upper end | Year-round, like any other room in the house |
The Biggest Price Factor: What You Already Have
Do you already have a screen porch with a solid floor and roof? That is a big head start.
Converting an existing porch usually costs much less than building from scratch. The foundation, framing, and roof are already there. We are upgrading what you have, not starting over. Learn more about screen room to sunroom conversions.
What Pushes the Price Up?
- Size. A large wraparound porch costs more than a small back porch.
- Glass vs. vinyl panels. Glass windows cost more than EzeBreeze vinyl panels.
- Insulation. A four-season room needs insulated walls, floor, and ceiling.
- Heating and cooling. Many heated sunrooms use a ductless mini-split system.
- Roof work. Building on an existing roof costs less than a new gable or shed roof.
- Electrical. Outlets, lights, and ceiling fans add cost.
- Flooring and finish. Tile, vinyl plank, or upgraded trim add up.
- An elevated deck. Second-story rooms need stronger support and stairs.
Three-Season vs. Four-Season: Is Heat Worth It?
| Three-Season | Four-Season | |
|---|---|---|
| Insulation | Minimal | Full |
| Glass | Single pane or vinyl panels | Insulated, energy-efficient glass |
| Heating and cooling | Usually none | Yes, often a mini-split |
| Use in a Raleigh January | Chilly | Comfortable |
| Use in a Raleigh July | Warm in the afternoon | Comfortable |
| Cost | Lower | Higher |
Our winters are fairly mild, so many families are happy with a three-season room. If you want an office, playroom, or guest space you can use every day, a heated sunroom is worth the extra cost.
Do You Need a Permit in Raleigh?
Yes. The City of Raleigh says a building permit is required for a sunroom, screened porch, deck, or similar structure. Other towns have their own rules. We will go over what your project needs during your free estimate.
How to Get the Most for Your Money
- Start with an existing porch if you have one
- Pick the room type that fits how you will use it. Do not pay for heat you will not use.
- Plan electrical now. Adding outlets later costs more.
- Ask about financing to spread out the cost
Sunrooms Around Raleigh
Screen porches are everywhere in Raleigh subdivisions. Many homes in Cary, Apex, and Wake Forest built in the 1990s and 2000s came with one. Those porches make great starting points for a sunroom because the roof and floor are already there.
Raised decks are common too, especially on sloped lots in North Raleigh and near Falls Lake. Enclosing a second-story deck can give you a treetop view, but it needs stronger support, which adds to the cost.
And if you are in a historic district like Oakwood or Boylan Heights, plan for extra review. Exterior changes there may need approval before work starts.
