Most San Antonio patios do not need a sunroom to get through winter. They need something to stop the wind, something to keep bugs out on the warm days, and one good source of heat for cold nights. Get those three right and the patio you live on in May still works at Thanksgiving.
What does a San Antonio winter actually ask of a patio?
Less than people think. The National Weather Service’s monthly normals for San Antonio put the normal January high at 63 degrees and the normal low at 41. Across a full year, the city averages about 14 nights at or below freezing, and most of them fall between December and February.
So the problem is rarely snow. It is the evening chill after a pleasant afternoon, and the wind that rolls through with each cold front.
There is a catch. The same normals show roughly 122 days a year at 90 degrees or hotter, with a normal August high of 96. Whatever you add for winter has to earn its keep in summer too. That is why so many winter conversations end with something that opens and closes.
Are screens or retractable screens worth it for winter?
For most families, yes, as long as you know what a screen does and does not do. Screens cut the wind, keep leaves off the cushions, and keep mosquitoes out during the warm, damp stretches of fall and spring. They do not hold heat. A screened-in porch will not insulate like a fully enclosed room, but add a heater or an outdoor fire feature and it stays comfortable well into the cooler months.
A fixed screened porch is built from wood, aluminum and screen fabric under a roof, and it can take ceiling fans, lighting and built-in seating. Retractable screens work differently. They roll up out of sight on a nice day and come down when a front blows in or the bugs show up. A single screen can typically be installed in a few hours; larger openings or several screens take longer. Plan on periodic cleaning and a little lubrication on the moving parts.
Lance called us to screen in his back patio. After we talked through ideas built around his budget, he expanded the project with financing. He put it best in his review:
“Only negative is I wish I had given them a bigger budget because now I want to spend all my time on my back patio.”

When does a full patio enclosure make sense?
When you want a room, not a porch. If the plan is breakfast out there every January morning or a playroom the kids use all year, screens alone will not get you there.
A patio enclosure closes in an existing patio or deck with aluminum, glass, vinyl or screen panels, depending on how much protection you want. Built one way, it is a three-season room. Built another way, it is a sunroom you use every month of the year. Inside an enclosure we can add ceiling fans, heaters and even air conditioning.
An enclosure is a bigger structure than a set of screens, which means a bigger permit and HOA conversation. We check what your address requires before we price it, and that paperwork is part of the job.
Fireplace, fire pit or heater: which heats a patio best?
Each one heats differently, so the right pick depends on how you use the space.
- Outdoor fireplace. The focal point. We build them in stone, brick and concrete. Heat comes out the front, so the seating faces it. See examples in our outdoor fireplaces gallery.
- Fire pit. Better for a group sitting in a circle, and a natural fit for the open part of the yard.
- Mounted heaters. The quiet workhorse under a patio cover or inside a screened porch. They warm the people underneath with no fire to tend.
Whichever you choose, plan the utilities with the build. The City of San Antonio’s Information Bulletin 151 says lighting, power receptacles and gas lines to equipment each need separate trade permits, with their own fees and inspections, applied for by state licensed trade contractors registered with the City. A gas line to a fireplace or a circuit for a heater is far easier to run before the ceiling and finishes go on. Clearances between a fire feature and a roof are set during design for the specific unit, so tell us early if you want fire under a cover.
Does a patio cover make winter better or worse?
Both, depending on the roof. A solid cover keeps you dry during a cold rain and blocks the sun all day, which is exactly what you want in August. In December, when the sun sits lower and you would like some of it, a solid roof also changes the light coming into the rooms beside it more than an open structure does. Our pergola vs patio cover comparison walks through that tradeoff, and it is why we look at sun angles and your roofline first.
That is where louvered and open-slat tops earn their place. Our aluminum patio cover lineup includes louvered systems with slatted tops that balance airflow and shade, plus solid privacy wall panels that double as wind blocks on the side where fronts hit. Add good lighting for the early sunsets, and the patio stays usable well into the evening.
What does it cost to winterize a patio?
It depends on what you combine, so we will not throw out one number here. The things that move the price:
- Fixed screen panels or retractable screens
- Enclosure materials: screen, vinyl or glass
- The heat source: a masonry fireplace with a gas line is a much bigger project than a mounted heater
- Whether a cover already exists or is part of the project
- Electrical and gas work, each with its own permit
Our patio cover cost guide covers what drives the price of the cover itself, including why we run wiring during the build: it is far cleaner and cheaper than retrofitting later. If the budget is the sticking point, financing is available through our lending partners, and our team helps you with the application.
Should you build now or wait for spring?
Build now if you can. Those same weather service normals put December highs in the mid 60s, which is comfortable working weather for a crew. Starting the design in late fall also gets HOA approval and any city permits behind you before the spring rush.
Frequently Asked Questions
Can you use a screened patio in winter in San Antonio?
Yes, on most days. San Antonio’s normal January high is in the low 60s, so a screened patio is comfortable most afternoons. Screens block wind and debris but do not hold heat, so for chilly evenings and the handful of freezing nights each year, add a mounted heater, a fire feature, or retractable screens you can lower when a front comes through.
Do I need a permit for an outdoor fireplace in San Antonio?
Plan on at least one. The City requires a separate trade permit for gas lines to equipment, applied for by a licensed contractor registered with the City, and new lighting or outlets need an electrical permit. Whether the fireplace structure itself needs a building permit depends on the project and the address, and your HOA may want to review it. We confirm both during design.
Is a patio enclosure the same as a sunroom?
Not always. An enclosure closes in an existing patio or deck, and the materials decide what it becomes. Screen or vinyl panels make a three-season room. Glass panels with heating and cooling make a sunroom you can use year-round. We build both and help you choose based on how often you plan to be out there.
Can you add heaters to an existing patio cover?
Usually, yes. Electric heaters need power run to them, and in San Antonio that work requires a separate electrical permit from a licensed trade contractor. Gas heaters need a gas line permit. Adding heat to an existing cover is doable, but it means retrofitting, which is why we suggest planning heaters with a new cover whenever possible.
