The patio you hardly use
Most of our calls start with a patio that sits empty because it's too hot or too buggy. A heated and cooled room over it gives you space you'll actually sit in.
Got a patio you hardly use because it's too hot, cold or buggy? We build a heated and cooled glass room you'll actually sit in.

Solarium installation in Mission Viejo means adding a fully enclosed glass room to your house that's heated and cooled and has all-weather windows, so you can use it in every season. Apex Mission Viejo Sunrooms and Patios has been building rooms like this since 2013.
Most people who call us have a patio or deck they hardly use because it's too hot in the afternoon or too cool at night. A solarium fixes that when it's sized right, sits on a sound base and is planned around the sun.
The price moves with the room's size, whether it's heated and cooled or a three season room, how much work your slab or deck needs, and the glass and insulation you pick. The schedule mostly turns on that base work and the city's permit steps. We're licensed and insured, we take care of the permit filing and inspection booking, and our written estimate after my visit gives you the figure for your own room.
I'll look at your yard and tell you on that first visit what kind of room makes sense there, so you know what fits before you spend anything on it.
I'd rather build the room you'll sit in every week than the biggest one I could sell you, because an oversized solarium costs more to build and more to heat and cool.
I come out to look at every job myself and our own crew does the build, so what we talked through at your house is what actually gets built.
I start under the room, because a solarium is only as good as the slab or deck it sits on. If yours needs work, I'll tell you on the first visit rather than find out after the walls go up, and we fix the base before we frame anything.
A room that's mostly glass gets hot fast, so I plan shade into it from the start. We size the roof overhang to keep the high summer sun off the glass and let the low winter sun in, which is the difference between a room you use every day and one you avoid every afternoon.
That planning happens in sunroom design, where we work out the size, roof and glass with you before anything gets ordered. If what you really want is shade and you'd rather keep the space open, patio cover installation is the simpler job, and I'll tell you on the visit which one fits how you'd use the space.

A deck that gets used a few weekends a year can carry a solarium if its framing is up to it, giving you a real room off the house instead of boards in the sun.
Because a solarium is heated and cooled like the rest of the house, it works as an everyday family or dining room, not just a spot for mild spring evenings.
A modest solarium off the kitchen or a bedroom makes a quiet place for a chair, a desk or plants, and it's often a better buy than a big room you rarely fill.
Send the form and we'll reply within one business day to set up a visit. I'll measure, look over your slab or deck and talk through the room with you, then we send a written estimate with no obligation.
I do every estimate visit in person, so the person who measures your yard and checks your slab or deck is the same one recommending the room.
We go over whether a solarium or a three season room fits how you'd use the space, so the estimate prices the room you want and not a guess.
That's our promise on every room we build, and it comes from the same people you met at the estimate, since our own crew does the work.
These examples show glass roofs, frame colors, overhangs and room layouts you can point to when we talk through your own room.
Here are the questions I hear most about solariums, from room type and cost to heat, insulation and the city's steps.
A solarium is fully enclosed, heated and cooled, with all-weather windows, while three season rooms, enclosed porches and enclosed patios usually aren't heated or cooled and have uninsulated windows or screens. Four season rooms and conservatories generally mean the same thing as a solarium. If you want to sit out there in both July and January, I'd go with the solarium.
A sunroom in Orange County usually costs about $120 to $170 per square foot, and that's the going rate across the area, not our price. Where your room lands depends on its size, whether it needs a new foundation, and whether it's heated and cooled. Our written estimate after the visit gives you the figure for your own room.
Plan shade into the design, because sun through the glass is usually the main cause of overheating. That comes from UK building guidance for temperate climates, and a university teaching module shows roof overhangs can block direct summer sun while letting winter sun in. Neither was written for Orange County, but both line up with how we size the overhang.
Settle insulation before building starts. One cost guide says insulated windows and wall, floor and roof insulation are much easier to put in while the room is built, and adding them later can often cost more. We go over those choices with you before the build so the room doesn't have to be opened back up.
In Mission Viejo, all permits and inspections are submitted and scheduled online through the city's Building Services. An inspection happens the next business day when it's requested before 4:00 PM. We do the filing and booking, which matters because if the city orders a job stopped, extra permit fees apply. Building Services also answers questions at (949) 470-3054.
Enter your address in the city's Interactive Map Viewer to see which zone your property is in. The city uses those maps to update its building codes, defensible space rules and fire safety policies, though they aren't a measure of immediate fire risk. It also adjusts state building codes for local climate, geology and terrain, so send us your zone before the visit.
Call (949) 619-8191, email quotes@missionviejosunroomsandpatios.com or use our contact form with your rough size, room type and fire zone so the first visit gets further.
