A three season glass room in North Louisiana typically costs $15,000 to $45,000 installed, with HomeGuide's 2026 sunroom guide putting the full three season range at $8,000 to $50,000 depending on size, roof and foundation. A glass room is the step past a screen room: sliding glass panels with screens behind them fill the openings, so you open it in April and close it in August. Donnie Grubbs builds them with a Structall insulated roof, aluminum framing and our own crews, and has enclosed porches in this climate since 1976.

We are a local home improvement contractor and we stand behind every job. You are not handed off to a subcontractor. Every job follows the same disciplined process:
A glass room earns its keep in North Louisiana because the weather swings so far. NOAA's 1991 to 2020 normals put July highs in the low to mid 90s and January lows in the 30s, with 50 inches or more of rain a year. On a mild spring evening you slide the panels open and the room works like a screen porch. When it is 95 degrees or 40 degrees you close the glass, and the Structall insulated roof holds the temperature well enough that a ceiling fan or a portable heater keeps the room usable. That is more living space than any other project short of a full addition, and Donnie Grubbs has built it in this climate since 1976.
A three season room is a glass enclosed space built for spring, summer and fall, without full heating and cooling. On the projects priced on this page, that means aluminum framing, an insulated aluminum roof and horizontal sliding glass panels that open to let air through on a mild day. If you think you may want year round use later, say so at the start so the room can be planned for it.
The price of a three season room comes down to a handful of choices. Size sets the baseline, because more square footage means more framing, glass and roof. Framing material matters, and the ranges on this page are for aluminum. Glass drives cost through the number of sliding panels and doors. The roof can be a new insulated panel or an existing cover. Some existing covers are thin metal and worth replacing. The foundation can be a sound existing slab, or a slab may need to be poured or extended. Electrical for ceiling fans and outlets adds to the total as well.
Site preparation deserves attention in North Louisiana. In Monroe, West Monroe, Shreveport and Bossier City, the median home was built between 1971 and 1979, according to the Census Bureau's ACS 5 year estimates for 2023. Before you compare quotes, look for cracks or settling in the slab, check that water drains away from the patio, and confirm the fascia where the new roof will attach is solid. Ask each contractor whether the permit and inspection are included in the price, so you are comparing the same scope.
The upside of a three season room is a usable outdoor space that keeps out rain, pollen and insects, opens up when the weather is pleasant, and costs less than a framed room addition. The tradeoff is comfort at the extremes: without heating and cooling, the hottest summer afternoons and the coldest winter mornings will be less pleasant, and glass facing strong afternoon sun holds heat. Donnie Grubbs, serving North Louisiana since 1976, prices each room from an on site measure so the number reflects your slab, roofline and openings.
A three season glass room in North Louisiana typically runs $15,000 to $45,000 installed, and HomeGuide's 2026 sunroom guide puts the full three season range at $8,000 to $50,000 depending on size, roof and foundation. A 10 by 14 room lands near $15,000 to $28,000, a 12 by 18 near $20,000 to $38,000, and a 14 by 20 near $26,000 to $50,000. Donnie Grubbs measures on site and gives you a free written price for the complete job.
A glass room encloses a patio with aluminum framing, a Structall insulated panel roof, and horizontal sliding glass panels with screens behind them. A sunroom usually has a shingled roof framed to match the house and larger fixed windows, so it sits closer to a traditional addition and costs more. A full conditioned addition adds foundation, framing, HVAC and drywall on top of that. Donnie Grubbs builds the first two and will tell you honestly which fits your house.
Yes, within limits. A three season glass room with an insulated roof holds temperature well, and most North Louisiana customers use a ceiling fan in summer and a portable heater on the few cold nights. If you want the room fully conditioned year round, a dedicated mini split can be added, and that is the point where a sunroom with insulated walls starts to make more sense.
In most cases, yes. If the framing is sound, sliding glass panels can replace the screen panels in the existing openings, and the screens stay behind the glass so you can still open the room up. Reusing the roof and framing puts the project at the low end of the glass room range. Donnie Grubbs confirms the structure at the free estimate.
Patio enclosure is the broad term for turning a covered patio into a room: screen panels make it a screen room, and sliding glass panels make it a glass room. Both sit on the existing slab under an insulated roof and are treated as patio covers under Louisiana's building code, not as habitable additions. Donnie Grubbs builds both kinds in North Louisiana.
Yes. Louisiana enforces the 2021 International Residential Code with state amendments, and an enclosed patio room needs a permit from the city or parish building office. Appendix AH allows enclosure walls of glass or screening on a patio cover as long as the structure stays one story, under 12 feet, and is used for outdoor living rather than as a bedroom or kitchen. Donnie Grubbs handles the permit as part of the job.
Most glass rooms are finished in about a week once materials arrive. The insulated roof goes up first, then the aluminum framing, the sliding glass panels and screens, the door, and the electrical. Converting an existing screen room is faster. Panels are made to your openings after the estimate, so allow a few weeks of lead time.
It adds usable square footage at a fraction of the cost of a conditioned addition, which is the main reason homeowners in North Louisiana build one. A glass room is not counted as heated living area on an appraisal the way a full addition is, so think of it as space you will use every week rather than a pure resale play. Donnie Grubbs will tell you at the estimate which option fits your goal.
The sliding panels sit in aluminum tracks with weep holes that drain rain to the outside, and the Structall roof joints snap together over a protected sealant reservoir. Single pane sliding panels do not have a sealed air space, so there is nothing to fog the way an old double pane window does. Donnie Grubbs sets the threshold and flashing so water goes where it should.

Yes, most screen rooms can be glassed in if the existing posts, roof connections and slab can carry the added weight and wind load of glass; if they cannot, the weak posts or beams are reframed first. The International Residential Code, in its optional Appendix AH for patio covers, allows enclosure walls of glass meeting the Section R308 safety glazing rules, or clear plastic no thicker than 0.125 inch, as long as the longer wall and one other wall stay at least 65 percent open or glazed below 6 feet 8 inches. That choice matters: vinyl panels are lighter and cheaper but scratch and cloud over time, while tempered glass seals tighter against pollen, rain and heat. A room built under Appendix AH stays a three season space for outdoor living, not a habitable room, so adding ducted heating and cooling, solid insulated walls or a shingled roof turns the job into a sunroom built to full addition rules, with a different permit and a higher price. Donnie Grubbs' own crews check post anchors, slab cracks and beam spans at the estimate to show which path a room needs.
Yes. If the aluminum framing is sound, horizontal sliding glass panels replace the screen panels in the existing openings and the screens stay behind the glass, so the room still opens up on a mild evening. Because the roof, posts and slab are already built, a conversion lands at the low end of the three season glass room ranges on this page, which HomeGuide's 2026 sunroom guide puts at $15,000 to $28,000 for a 10 by 14 room, $20,000 to $38,000 for a 12 by 18 and $26,000 to $50,000 for a 14 by 20. Three things move a conversion up: openings that have to be reframed to take a standard panel, a thin metal roof that should be replaced with a Structall insulated panel at the same time, and adding electrical or a mini split for year round use. Donnie Grubbs confirms the structure at the free estimate and sizes new screen rooms for glass from the start when it is the long term plan.
A three season sunroom, built as a glass room with an insulated aluminum roof and sliding glass panels, typically costs $15,000 to $45,000 installed in Louisiana, inside the $8,000 to $50,000 three season range in HomeGuide's 2026 sunroom guide. By size, a 10 by 14 room lands near $15,000 to $28,000, a 12 by 18 near $20,000 to $38,000 and a 14 by 20 near $26,000 to $50,000. Converting an existing screen room sits at the low end because the framing and roof are already in place. A sunroom with a shingled roof and fixed windows prices above the glass room range and behaves like a room addition, since it needs roof framing tied into the house. Within a range, the number moves with square footage, the count of sliding panels and doors, whether a slab must be poured or extended, and electrical for fans and outlets. Donnie Grubbs prices the complete job from an on site measure, and the same crews build it.
