Is a solarium the right room for your Riverside house?
Solarium installation in Riverside, CA means adding a one-story room to your house with glass making up a large share of its walls and roof. Like a four-season room, it's fully enclosed and heated and cooled, so you get daylight from overhead in a room you can use in any weather.
Most people who call me already have a covered patio or an open spot off the back of the house, and they're deciding between a solarium and a simpler three-season room. The price moves with the size of the room, whether it needs a new foundation, how much of the roof is glass, the frames and glass you pick and whether it gets heating and air. The schedule turns on most of the same things, because foundation work and outside trades each take their own time. After my visit you get a written estimate that puts your choices in one place.
How do you know a solarium makes sense for your house?
A patio you skip half the year
You have a covered patio you'd like to use more, but it's too hot some months and too cold others. A cover only gives shade, so closing it in with glass and heating and cooling is usually what turns it into a room, and every season you wait is another one spent indoors.
Back rooms that stay dark
The rooms at the back of your house need lights on at midday, and you want daylight without knocking out a wall of the house. A glass roof brings light in from above in a way a solid roof can't.
A glass room that's too hot
You already have a sunroom with glass overhead and it's too warm to sit in by early afternoon. That usually means the roof has no shade or the frames are passing heat through, and waiting means a room you avoid and furniture that fades.
How we plan and build a solarium
I start by measuring, looking over what's there now and checking what the room will sit on, because a base that moves will stress the glass and open up leaks. With that much glass overhead, we plan shade for the roof from the start, since a glass roof takes in far more sun than a wall does, and we talk through frames that let less heat and cold pass through. We settle the windows and the insulation in the walls, floor and roof up front too, because highly insulated windows and insulation make a sunroom more energy efficient, and they're much easier to put in while the room is built than later, when adding them can cost more. Then our crew builds the base, sets the frame, puts in flashing, the strips that turn water away, where the room meets your house and the floor, and installs the glass.
Not everyone who calls ends up with a full glass room. If you mostly want shade over the patio, patio cover installation is the simpler job, and if you're still working out size, roof and layout, our sunroom design work is where we settle that before any building starts.
Full glass roof with shade planned in
This suits you if you want the most daylight and sky overhead. We plan the outside shade along with the roof, so the room isn't too bright and warm to use at midday.
Aluminum frames with a thermal break
One maker's specification calls for aluminum frames with a thermal break, a barrier inside the frame, and says it greatly cuts the heat and cold passing through. It also says this reduces condensation on and inside the frame, which matters if you want a room that's comfortable year-round.
Closing in the patio you have
This suits you if you already have a covered patio off the back of the house and like where it sits. Whether we can build on the slab you have depends on what we find when I check it.

Attaching a glass room starts with what your lot allows, and the city says its zoning map is for reference only and can change, so I check current zoning and land use with the city's Planning Division instead of going by the map. How the room ties into the house matters too. State law says a residential remodeling contractor can't contract to change load-bearing parts of a house, such as footings, foundations, load-bearing walls and roof structures, and installing the glass and frames falls under the state's separate glazing contractor license. On a solarium that ties into your roof, it's fair to ask any contractor which license covers each part of the work.
We're based in Riverside and work in many of the cities around it in Riverside County and San Bernardino County, so if your city isn't listed, ask us. A lot of our solarium calls, here and on jobs in Corona and Redlands, start with a covered concrete patio off the back of the house, and an older slab often needs work before it can carry a glass room.
What happens when you call about a solarium in Riverside?
Call or send a request
Call (951) 394-2905 or use the form, and we'll set up a time for me to come out. It helps to tell us the room size you have in mind and whether you plan to use it year-round.
I measure and look it over
I measure, look over the patio or wall the room will attach to and talk through how you'll use it. Then I send you a written estimate, so you can see what the room you picked covers before you decide anything.
We handle paperwork and build
When the job needs a permit, we find out which office covers your address, prepare and file the paperwork and meet the inspector on site. Our installers build the room with me, and we bring in licensed trades for the electrical and heating and cooling work.
Walk through the finished room
At the end we walk through the room with you, glass, shade, doors and all. It's the time to ask about anything you want to see working before we leave.
Frequently asked questions
How much does a solarium cost in Riverside, CA?
A sunroom in Riverside usually costs about $95 to $200 per square foot, and that's the going range for the area, not our price. Larger rooms that need a foundation and have heating and air conditioning fall toward the higher end of that range. Your written estimate after my visit gives the figure for your room.
What's the difference between a solarium and a three-season room?
A solarium is heated and cooled with all weather windows, while three-season rooms, enclosed porches and enclosed patios are generally not heated or cooled and have uninsulated windows or screens. If you want to use the room in every kind of weather, you're choosing a solarium. A three-season room is the simpler build and suits a space you'll mostly use when the weather's mild.
Who is allowed to build a solarium in California?
In California, anyone who contracts for work worth $1,000 or more in combined labor and materials needs a current, valid license from the Contractors State License Board. A general building contractor taking on specialty work has to hold that specialty license or have a specialty contractor do it, and when a job needs more than two types of work, that contractor may contract for and oversee the whole project. A solarium usually involves framing, glass, electrical and heating and cooling, so ask who's running the whole job.
What causes a sunroom with a glass roof to get so hot?
Sun coming straight through the roof glass is the main cause, and shading guidance written for Australian homes says roof glass takes in almost twice the heat of an unshaded west-facing window of the same area. A national passive solar design guide adds that clear glass lets through nearly 90% of the sun's heat, warming the room like a greenhouse. The Australian guidance says to shade roof glass from outside with blinds or louvres, which is why shade is part of our plan from the first visit.
How do I clean the roof panels on a solarium?
One supplier's guide says to clean its sheet panels with warm water, a mild dish soap and a soft cloth, then rinse and dry them, with no scrubbing, scraping or solvents. It says cleaning that way extends the life of the sheets. That guide is for one maker's panels, so check the instructions for the panels on your own room.
Can a solarium be built on my existing patio slab?
Sometimes, but I won't know until I've checked the slab, because the room is only as good as what it sits on. On my visit I look at its condition, how water drains off it and where it meets the house. If it can't carry a glass room, we'll talk through a new foundation and what it adds.
