A sunroom contractor in Lakeland builds a glass room off the house. Windows, doors, aluminum frame, and a permit. People here still say Florida room when they mean the same job.
True Aluminum frames that room. License SCC131151391. Licensed trades finish cooling. We do not run plumbing, electrical, or HVAC. Call (863) 804-6021 if you want the room measured.
What the contractor actually builds
Three-season rooms stay weathertight without living-space insulation. The contractor sets the aluminum frame, the glass, the doors, and a roof that sheds Polk County rain. The room is comfortable most of the Central Florida year. It runs hot on a July afternoon unless you move air and shade the west side. That shade is usually an awning or planting, not a second structure.
Four-season rooms get the glass, the roof, and the blocking so a licensed cooling contractor can set a mini-split or a tie-in. Insulated walls, insulated roof, insulated glass. That is the room you count as a den or office. Ask which one you want before anyone draws the walls. Converting later means opening those walls back up.
A lanai screen is mesh and breeze. It is not this job. If you want bugs out and a roof, start on the lanai page. If you want glass you can sit in during a storm, you want a sunroom contractor.
We already wrote the cost ranges and the vocabulary. This page is the hire question. Who frames it, who pulls the permit, and who does not touch the refrigerant.
What happens on the first visit
The contractor walks the wall you want to open. They measure the span, the existing roof line, and the slab. They ask if you will sit in the room in August with the door closed. That answer sorts three-season from four-season before anyone prices glass.
They also look at load. Glass weighs more than screen. A thin patio pad that held mesh may not hold a glazed wall. If the footers are short, the quote includes new ones, or it says start over. Guessing that over the phone is how people buy a sunroom on a lanai slab that cannot take it.
You get a written scope after that visit. Catalog square-foot numbers are planning bands. They are not the job at your address.
How the permit path works in Lakeland
A sunroom is a structural addition. There is no dollar cutoff that lets it skip the permit. Florida’s small-project exemption does not cover structural aluminum. City of Lakeland Building Inspection issues the permit inside city limits. Applications go through the city’s iMS system. Sealed drawings upload to ePlan. Unincorporated Polk County goes to the Polk County Building Division.
The contractor pulls that permit. If a quote asks you to pull it as owner-builder, you take the code liability the license is supposed to carry. License SCC131151391 is the aluminum specialty number on this work.
When the contract is over $5,000, Florida also wants a recorded Notice of Commencement on file with the permit office before the first inspection. That is routine paperwork. The inspection does not happen without it.
A three-season room and a four-season room are different drawings. The inspector is looking at the room you said you wanted, not a screen enclosure someone renamed.
Converting a lanai instead of starting new
If you already have a covered, screened space, conversion is often cheaper because the slab, footings, and roof are already paid for. The contractor still checks three things before calling it a conversion.
Is the slab thick enough to hold anchors and the extra wall load. Are the existing footings sized for glass. Can the existing roof carry the load and flash cleanly where it meets the house. If any of those fail, the fix goes in the price. There is a point where tear-out is cheaper. They should say which path you are on before you spend.
A screen room on a thin pad is not a sunroom waiting to happen. Paying glass money for a rescreen is the other mistake. If the mesh is torn and the bars are still true, that is screen repair in Lakeland FL.
What sits in the aluminum contract
The aluminum contract is the frame, the glass package you picked, the doors, the roof, flashing at the house, and the permit path. Gutters on the new roof line are a separate line if you want them sized with the room. Pavers under the room, sloped away from the house, are a separate line if the dirt is still dirt.
Cooling is a separate ticket. Outlets are a separate ticket. The sunroom contractor does not run refrigerant or wire the room as this company. A licensed electrician or AC contractor finishes that work after the walls are up.
Ask whether cooling is in the aluminum contract or a later visit. Ask who pulls the permit. Ask for the price in writing after a measure, not off a catalog.

What rides with the room
A new roof line needs gutter installation sized to the run. Five-inch or six-inch seamless K-style, cut on site. Dirt under the room wants pavers sloped away from the house before the posts go in. Those are separate line items. They are not a kitchen remodel and they are not plumbing.
Plant City is the shop. This page is Lakeland. Winter Haven and Auburndale stay on the same run.
