Sunroom Builders in Austin: Three & Four Season Rooms and Screened Porches

A screened porch or sunroom is the answer to the two things that chase Texans back indoors: mosquitoes and heat. We've been building outdoor structures in Central Texas since 1984, and screen rooms and sunrooms are where all that experience comes together - roof framing, proper attachment to your home, drainage, and the finish details that make a space you'll actually live in. Whether you want to screen in an existing covered patio or build a fully insulated four-season sunroom from the slab up, we design it, permit it, and build it with the same crew from the first post hole to the final walkthrough.

Sunrooms & Screened Porches

From Our Team (40+ Years Building Outdoor Structures)

Here's the honest truth about screen rooms: the screen is the easy part. What separates a screened porch that lasts from one that sags and leaks is everything around the screen - the roof connection to your house, the flashing, the kick plates at the bottom that take the beating from weed eaters and dogs, and the framing that holds tension on every panel. We've repaired plenty of screen rooms where someone stapled screen to skinny framing and called it a day. Two Texas summers later the panels are wavy, the door doesn't close, and water is getting into the wall where it attaches to the house. When we build a screened porch, we frame it like the room addition it actually is. Same thing goes for sunrooms, only more so - a sunroom is conditioned or semi-conditioned space attached to your home, and if the structure, glazing, and waterproofing aren't right, you'll feel it every August and see it on every electric bill. My dad started this company in 1984, and the rule he drilled into me still applies: build the parts nobody sees like everyone will see them.

Why It Matters

Central Texas has one of the longest mosquito seasons in the country - roughly February through November in a warm year. That means an open patio is a battle for most of the year, and an uncovered one is unusable all summer. A screened porch gives you the breeze without the bugs. A sunroom goes further: real windows, real comfort, and usable square footage in January and August alike. Either way, you're converting space you avoid into space you live in - and quality enclosed outdoor space is one of the features Austin-area buyers consistently pay attention to.

Bug-Free Outdoor Living

Mosquitoes are the number one reason Central Texas patios sit empty. A properly built screen room ends that problem completely - evenings on the porch from spring through fall without a citronella candle in sight. We build tight: screen panels tensioned correctly, doors that seal, and no gaps at the roofline where bugs sneak in.

Built as a Real Structure

We don't staple screen to an existing patio and call it a screen room. We frame screened porches and sunrooms as true structural additions - engineered posts and beams, proper roof tie-in, correct flashing where it meets your house. That's the difference between 5 years and 30 years.

Three Levels of Enclosure

Screened porch, three-season room, or four-season sunroom - we build all three and we'll tell you honestly which one fits your budget and how you'll actually use the space. Plenty of clients start with screens and upgrade to windows later; we can design for that from day one.

Convert What You Already Have

If you have a covered patio or a solid deck, you may be closer to a screened porch than you think. We assess the existing structure, tell you straight whether it can carry the new loads, and quote the conversion at a fraction of a ground-up build when the bones are good.

Permits & HOA Handled

Enclosing space attached to your home requires permits in every Central Texas city, and sunrooms often trigger energy code review. We handle all of it - permit applications, HOA architectural submissions, inspections. It's included in your fixed written quote.

Fixed Pricing, Real Warranty

Your quote is your price - no allowances that balloon, no surprises after demo. We back our workmanship for a full year in writing, and your materials carry manufacturer warranties up to 50 years. We've been standing behind our work since 1984.

Our Process

1

Free On-Site Consultation

We come out, look at your existing patio, deck, or the spot where the room will go, and talk through how you actually want to use the space. Bug protection only? Rain protection? Year-round comfort? The answer determines whether you need screens, windows, or full insulation - and there's a real price difference between them, so we get this right before anything else. You'll have a free quote within 24 hours of our visit.

1-2 hours

Design & Fixed Written Quote

We design the room to match your home - roofline, siding, trim, window styles - and give you a fixed written price covering everything: structure, screens or glazing, electrical, permits, and cleanup. If we're converting an existing structure, the quote reflects exactly what can be reused and what needs reinforcement. No allowances, no surprises.

3-7 days

Permits & HOA Approval

Screened porches and sunrooms attached to your home require permits in every Central Texas municipality, and conditioned sunrooms also go through energy code review. We prepare and submit everything, including HOA architectural applications. We've built in every city we serve and we know what each one wants to see.

Frequently Asked Questions

Both. We build three season rooms, four season rooms and screened porches as one crew, from our shop in Liberty Hill. A three season room uses sliding vinyl windows over knee walls and runs about $120 to $220 per square foot installed, or $30,000 to $48,000 for a 12x14 room. A four season room adds insulation, dual-pane low-E glass and heating and cooling, and runs about $200 to $350 per square foot, or $55,000 to $90,000 for a 14x16 room. We handle the design, permit, energy code review and HOA approval, and quote the whole job at a fixed price.

Yes. Screened porches are one of our most requested projects in Austin and the surrounding suburbs. Screening in an existing 12x16 covered patio typically costs $8,000 to $14,000. A new 14x16 screened porch with its own roof and structure typically runs $22,000 to $35,000. We frame the screen walls like a real room, seal the roof connection and doors, and pull the permit, so the porch stays tight and bug free for years.

Yes. A four season room (four-season sunroom) is a true room addition: insulated walls and roof, dual-pane low-E glass, and heating and cooling, usually a mini-split. They typically run $200 to $350 per square foot installed, or about $55,000 to $90,000 for a 14x16 room. We frame it into your existing roofline, handle the permit and energy code review, and quote it at a fixed price.

A screened porch is an outdoor room: a solid roof with screen walls instead of glass. You get the breeze, you keep the bugs out, but the temperature is whatever it is outside. A sunroom replaces the screens with real windows. A three-season sunroom uses single-pane or vinyl windows and stays comfortable most of the year; a four-season sunroom adds insulation, dual-pane glass, and heating and cooling so it's genuinely part of your house. Cost-wise, a screened porch is the entry point, a three-season room is roughly double, and a four-season room is a true room addition. We build all three and we'll tell you honestly which one matches how you'll use the space.

If you already have a solid covered patio, screening it in typically runs $8,000 to $14,000 depending on the size and number of openings. Building a new screened porch from scratch - roof, structure, and screens - usually falls between $22,000 and $40,000 for the sizes most families want. Sunrooms run higher: three-season rooms commonly land between $30,000 and $50,000, and four-season insulated sunrooms range from $55,000 into six figures for large ones. Every quote we give is fixed and in writing, so the number you approve is the number you pay.

Usually, yes - and it's one of the most cost-effective projects we do. The catch is that your existing structure has to be up to the job. Screen walls add wind load, and a door needs solid framing. We inspect the posts, beams, footings, and (for decks) the joists and ledger before quoting. If the bones are good, we build screen panels between the existing posts and you have a screened porch in a week or two. If something needs reinforcement, we tell you exactly what and why before you commit.

Yes. Anything enclosed and attached to your home requires a building permit in every city we serve, from Austin to Georgetown to Liberty Hill. Screened porches are usually a straightforward structural permit. Sunrooms - especially four-season rooms with heating and cooling - also go through energy code review, which means insulation values and window specs get checked. Many HOAs require architectural approval on top of that. We handle all of it as part of every project; you just sign where we tell you.

Yes, if it's built tight - and that's the whole game. Standard fiberglass screen stops mosquitoes easily; the failures happen at gaps, not through the mesh. Sloppy panel edges, doors that don't seal, and openings at the roofline are where bugs get in. We spline our screens into proper frames, use self-closing doors with good sweeps, and seal the roof connection. If you're near water or ranch land where tiny no-see-ums are the problem, we can install finer 20x20 mesh that stops those too.

This is the question to ask before you build, and the answer depends on the room. A screened porch with a ceiling fan is often the most comfortable option in summer because the breeze moves through. A three-season sunroom with the windows open behaves like a screened porch; closed up without conditioning, it will get hot in July, especially facing west. A four-season sunroom with insulated glass and a mini-split stays as comfortable as your living room in August. We look at your sun exposure during the consultation and design accordingly - roof insulation, low-E glass, shade orientation, and ventilation all matter more here than they do up north.

Standard fiberglass is the workhorse: affordable, easy to see through, and simple to replace panel by panel if one ever gets damaged. Aluminum screen is stiffer and more durable but shows dents. Pet-resistant mesh is a heavy vinyl-coated polyester that shrugs off dogs and cats - worth every penny if you have either. Solar screen blocks a big share of heat and glare on west-facing exposures. And fine 20x20 no-see-um mesh stops the tiniest biting insects. Most porches use standard fiberglass on most walls with upgrades only where they earn their keep, and we'll tell you where that is.

Screening in an existing covered patio is quick: usually 1-2 weeks of construction. A new screened porch with roof and structure takes 3-5 weeks. Sunrooms take longer - typically 4-8 weeks depending on size, glazing, and whether we're conditioning the space. Permits add 2-6 weeks before construction begins, with conditioned sunrooms at the longer end because of energy code review. We give you a realistic timeline with your quote, and because the same crew stays on your job start to finish, the schedule we give you is one we can actually keep.

Yes. A four-season room is heated, cooled, insulated, and wired like any room, so it works as an office, playroom, or breakfast room year round. Plan outlets, data, and lighting during design, and think about glare on screens from west or south windows. Low-E glass and blinds handle most of it.

Sometimes, but it is rarely cheap. Going to four-season usually means replacing the windows with dual-pane low-E units, insulating the roof, walls, and floor, and adding a mini-split, which is most of a new room. If there is a chance you will want year-round use, framing and insulating for it during the first build costs far less.

A four-season room needs a foundation that can carry insulated walls, a heavier roof, and glass, so it gets new footings or a slab designed for it. A screened porch can sometimes use an existing patio or deck if the structure checks out. We inspect what is there before we quote, and we tell you plainly if it needs reinforcement.

Screened porch, three-season, or four-season room compared

Pick by how many months you want to use the room and whether it needs to be cooled. A screened porch is open air with bugs kept out. A three-season room adds windows but no heating or cooling. A four-season room is insulated and conditioned like the rest of the house.

Cost follows that ladder. Screened porches run $30 to $55 per square foot installed, three-season rooms $120 to $220, and four-season rooms $200 to $350. On a 14x16 footprint, that is a new screened porch at $22,000 to $35,000 and a four-season room at $55,000 to $90,000.

Comfort follows it too. A screened porch with a ceiling fan feels good most of the year because air moves through it. A three-season room is pleasant from fall through spring but hot in July with the windows shut. Only the four-season room holds indoor temperature in August and January.

Permits and HVAC round out the comparison. All three need a building permit when attached to the house. The four-season room also goes through energy code review for insulation and window ratings, and it needs a heating and cooling plan, usually a ductless mini-split.

What is a four-season room?

A four-season room is a sunroom built like an addition to the house: insulated floor, walls, and roof, dual-pane low-E glass, and its own heating and cooling. The name means it stays comfortable in every season, not just the mild ones.

It is not a porch with windows added. The glass is rated for energy code, the roof carries insulation that has to meet code values, and the room ties into the house the way a bedroom addition would. Low-E glass matters a lot here because it cuts the solar heat that turns a west-facing glass room into an oven by late afternoon.

What makes a sunroom a true addition, not a kit

A true addition sits on a real foundation, is framed on site, and shares a roofline, siding, and trim with the house. It is permitted and inspected as part of the house, and from the street it looks original.

Kit sunrooms bolt aluminum frames to a slab or deck and stand apart from the house architecture. They are often sold at prices close to a site-built room. We frame sunrooms on site so the roof ties into yours, the flashing is continuous, and the room can be heated, cooled, and furnished like any other room.

Site-built also means you can plan an upgrade path. Frame a screened porch with walls and headers sized for windows, and you can add glass later without rebuilding the structure.

Heating and cooling a Central Texas sunroom

A ductless mini-split is the usual answer. It cools and heats the room on its own thermostat, avoids overloading the home's central system, and does not require new ductwork through the attic.

Size it for the glass, not just the square footage. A room with three walls of windows facing west needs far more cooling than the same size room facing north. Roof insulation, low-E glass, and an overhang or shade on the west side reduce the load, and they cost less than a larger unit running all summer.

Converting an existing patio or deck

The cheapest room is often the one you already have a roof for. Screening in a sound 12x16 covered patio runs $8,000 to $14,000, a fraction of the $22,000 to $35,000 for a new 14x16 screened porch with its own roof and footings.

The existing structure has to earn it. Screen walls and a door add wind load the original posts and beams were never designed for, and a sunroom adds glass weight on top of that. We check the posts, beams, footings, and the roof tie-in before quoting. If something needs reinforcing, the fixed quote says exactly what and why.

Decks can convert too, but the joists, ledger, and footings get a closer look, because a deck frame built for foot traffic now carries walls and a roof. On many older decks the right move is to rebuild the frame under the new room rather than trust it.

Motorized retractable screens are a middle option at $3,500 to $7,000 per opening. They stay rolled up most of the day and drop when the mosquitoes come out, which suits large openings and outdoor kitchens where fixed screen walls feel closed in.
