Solarium installation in South Gate CA - a glass room you'll actually use
Tired of a bare patio out back? We build a glass room shaded for the sun and planned around how you'll use it.

What does adding a solarium in South Gate involve?
Solarium installation in South Gate means building a glass sunspace against your house, with glass panels, frames and doors set on tracks fastened to a foundation, so you get a bright, enclosed room right next to the living space you already have.
Most people who call me have a patio slab or an old porch they're tired of looking at and want a room there instead. The price moves with the size of the room, whether it's heated and cooled like the rest of the house, how much glass and shading it takes, and whether the slab needs repair before anything sits on it. The schedule mostly turns on which city approvals your room needs. I look at the slab, deck or wall the room ties into before I put a number on paper, and the written estimate spells out what's in it and what isn't.
How we handle solarium installation
On a solarium, the talking comes before the tools. A room that's mostly glass lives or dies by which side of the house it faces and how it's shaded, so we settle that first, along with whether it's a sunspace you'll step into or a room you'll live in, since that answer changes the glass, the heating and cooling, and the approvals. A sunroom nobody sits in because it's too hot is just an expensive porch. Once the plan is set, our crew gets the base ready, fixing the slab or building a new foundation where it needs one, fastens the tracks, stands the frames, sets the glass panels and doors, and ties the roof into the house so water runs off instead of in. Then we put in the lighting, finish the trim and clean up.
A patio cover installation beside the solarium gives you a shaded spot outside its doors and keeps hard afternoon sun off that wall. If you're still deciding where the room should go or how much glass it really needs, our sunroom design work sorts that out on paper before anyone cuts anything.
What South Gate requires for solarium installation
Permits here go through the city's Building and Safety Division, which says a permit is typically required for any construction project. Its permit list doesn't name solariums, so I don't guess. We find out what your room needs and take care of the permit steps. Some projects need the Planning Division to approve a set of architectural plans before Building and Safety sees them. New construction valued over $50,000, judged by the scope of work, or over 800 sq ft also needs Public Works review and approval, and the city's checklist calls for approval from AQMD, the regional air quality agency, when work disturbs a bearing wall or the roof structure. That's why I ask early how big the room will be and how it meets the house, because those two answers decide which reviews come first, and I'll tell you up front if yours needs any.
Most solariums we build here go behind older one-story houses, onto patio slabs and porches that have been out in the weather a long time, so the room has to fit the house as it really is. We see the same houses on jobs in Lynwood and Huntington Park. We're based in South Gate and work the cities around it plus the nearby county areas, where a different office may handle permits, so we find out which one covers your address before anything gets drawn.
How a solarium job goes
Call and I come out
Call (213) 376-0861 or send the form, and I come out to look at what the room will sit on. I'll ask how you plan to use it and which part of the yard takes the afternoon sun.
Read your written estimate
You get a written estimate that says what's in it and what isn't, so a slab repair or an extra review doesn't turn up later as a surprise. If the room comes in over what you wanted to spend, I'll show you where a smaller or unheated room saves money, because I'd rather sell you the cheaper room than the wrong one.
We permit, build and walk it
We take care of the permit steps, tell you early if plans or reviews come first, then our crew builds the room while I check on it as it goes up. When it's finished, I walk the room with you before we call it done.

Get a written estimate for your solarium
We reply within one business day to set a time, and I come out to look at the slab, deck or wall the room will tie into. The estimate is free, done on site and comes with no obligation, and you'll have it in writing.
Questions before you add a solarium
What does a solarium cost around Los Angeles?
A 3-season or fully insulated 4-season sunroom in Los Angeles County usually costs about $17,000 to $60,000 per job. That's the going rate in the county, not our price, and where a solarium lands depends mostly on its size, whether it's heated and cooled, and how much work the slab needs. Our free on-site estimate gives you your own number in writing.
Do I need a permit for a solarium in South Gate?
Plan on one, because the city says a permit is typically required for any construction project. We take care of the permit steps with Building and Safety, and the bigger the room or the more it opens into the house, the more reviews it can pick up first, as covered above.
Does an unheated sunroom have to follow the California Energy Code?
Not all of it, if it stays separate from the house. State Energy Commission guidance says a sunspace that isn't heated or cooled, with an air and thermal barrier between it and the house, falls outside the code's rules for heating systems and the room's shell, though it still has to meet the lighting rules. A building official can require heating and cooling if the room looks like living space, so if you plan to live in it, we plan for the full energy rules from the start.
Can a solarium go on my existing patio slab?
Often it can, if the slab sits higher than the ground around it and isn't badly broken. One maker's installation guide says standing water can get into the tracks and the room when it doesn't, and that hairline cracks are fine but large buckled sections need repair first. I check both on the first visit so any repair is in the estimate.
How do I keep a solarium from getting too hot in Southern California?
Put the most glass where the sun is easiest to control, and shade the sunny side well. Federal guidance for cooling climates favors north-facing windows and generously shaded south-facing ones, using overhangs, landscaping, shutters or solar screens to cut heat gain in full sun. We plan that shading along with the room, not after you've already cooked in it.
How do I take care of a solarium once it's built?
Check the roof and gutters once a year and keep the weep holes, the small drain openings in the frame, clear so water can get out. One maker also suggests keeping door and window tracks clean and using a pure silicone spray on them, since oil-based lubricants tend to pick up dirt.
Why South Gate homeowners call South Gate Sunrooms & Patios for a solarium
I look at every job
I come out to every estimate myself, and our own crew does the building while I check on the work as it goes up. You're not handed off to a stranger between the price and the build.
Building sunrooms since 2017
We've built sunrooms and patio rooms for 9 years, and I framed houses long before that. That's long enough to know which glass rooms get used and which ones turn into storage.
Licensed and fully insured
We're licensed and fully insured, and California's state licensing board defines general building work as structures that enclose people using at least two unrelated trades, with a separate glazing class for installing glass, frames, panels, sashes and doors. A solarium involves both kinds of work, so it's worth asking any contractor what their license covers.
On a solarium, the sun decides whether you'll use the room, so that's where the conversation starts. Ask for an estimate and I'll come take a look.
