Sunroom Construction in Central FL

Half the people who call us say sunroom and half say Florida room, and most of them mean the same thing: a glassed-in room off the back of the house that you can sit in when it rains.

There is a difference in how the words get used, though, and it matters when you are pricing a job. A Florida room is the older local term for a room added onto the back of a house with a lot of glass, often built on an existing slab and often not tied into the home air conditioning. A sunroom is the broader term the industry uses, and it covers everything from that same three-season room up to a fully insulated, conditioned addition. A lanai is not either one: it is roofed and screened, not glazed. A screen room is the same idea without the attachment to the house roofline. And every so often the room somebody describes turns out to be an aluminum pergola, posts and slats with no walls at all.

We build all of it. If you tell us Florida room, we will ask two questions to sort out which room you actually want: do you want to sit in it in August, and does it need to hold conditioned air. The answers put you in the next section.

A three-season room is glazed and weathertight but not insulated to living-space standards and not tied into the home cooling system. It is comfortable most of the Central Florida year and hot in the middle of a July afternoon unless you move air through it and shade the west side, which is usually an awning or planting rather than anything structural. It is the cheaper room by a wide margin.

A four-season room is built as living space: insulated walls and roof, insulated glass, and a cooling source, whether that is a tie-in to the house system or its own mini-split. That is the room you use every day of the year, and it is roughly double the three-season room per square foot because of the insulation, the glass, and the slab and footing requirements that come with a conditioned addition.

If the honest answer is that you want the room mainly for mornings, evenings, and the cooler months, a three-season room with good glass and a ceiling fan does the job. If you are counting the space as a bedroom, office, or den, build it as four-season the first time. Converting later means opening the walls back up.

There is no Florida-specific published pricing for sunrooms that we would put our name to, so the figures below are national market data. Treat them as a planning range, not a Central Florida quote.

National cost guides put a three-season sunroom or Florida room at $80 to $230 per square foot, or roughly $8,000 to $50,000 total. A four-season room runs $200 to $400 per square foot, or $20,000 to $80,000. Angi reports a higher floor for full additions: an average of about $47,000 with most projects between $22,000 and $75,000 at $150 to $300 per square foot. The two disagree because the lower guides include prefab kits and simple conversions while Angi is describing site-built additions. Both are honest, they are counting different jobs.

These are general market ranges from public cost data, not True Aluminum prices and not a quote. Sunrooms vary more than any other job we do. Call (863) 804-6021 and we will come look at the slab.

What moves the number: three-season versus four-season is the single biggest jump, then whether you are building on an existing slab or pouring new, vinyl window versus insulated glass, roof type and span, and whether the room gets its own cooling unit. Permits on a sunroom run $250 to $1,500 nationally, which is real money and worth asking about before you sign anything. Financing is available if the room you want is bigger than the budget in front of you.

If you already have a covered, screened space out back, converting it is usually cheaper than building new, because the slab, the footings, and the roof are already there and paid for. National guides put converting a deck or patio into a three-season enclosure at $8,000 to $30,000.

Usually is doing work in that sentence. Before we quote a conversion we check three things. Is the slab thick and sound enough to hold anchors and take the added wall load. Are the existing footings sized for a glazed wall, which weighs considerably more than screen. Will the existing roof carry the load and can it be flashed and sealed properly where it meets the house. If any of those come back short, the fix goes in the price, and there is a point where tearing out and starting over is the cheaper path. We will tell you which one you are looking at before you spend anything.

Conversions are also a good moment to handle the ground around the room. A paver patio outside the new door, or an aluminum pergola over the leftover open section, is far easier to do while the crew is already on site.

The determining question is narrower than most people expect: does the room count as heated and cooled living space on the appraisal. A permitted four-season room with a cooling source generally can be counted in the home square footage. A three-season room generally cannot, no matter how nice it is, so it shows up as an amenity rather than as added square feet.

The other half is the permit. An unpermitted addition is a problem at closing, when the buyer agent pulls county records and finds a room that does not exist on the property card. We pull permits on every sunroom we build, and you keep that paperwork.

We are not going to quote you a return percentage. Central Florida resale depends on the neighborhood, the comps, and the buyer, and any number we gave you would be invented.

If your room has screened sections alongside the glass, those panels are on their own replacement clock and our rescreening crew handles them. Our True Home Membership rolls the seasonal inspection and the small fixes into one plan so nothing sits until it becomes a repair.

Most sunroom jobs touch something else on the property. Homeowners who want the pool covered too add pool cages, and a sunroom roof always needs somewhere to send its water, which is where seamless gutters come in.
