Solarium installation in Rancho Cucamonga CA - a glass room you can use year-round
Patio sitting empty most of the year? We build a glass room onto your house, with heating and cooling planned in from the start.

What does it take to add a solarium to your house?
Solarium installation in Rancho Cucamonga means building a glass room onto your house that ties into its walls, its roof and, if you want, its heating and cooling, so the yard becomes space you actually live in.
Most people who call us have a patio or deck they hardly use, and some are stuck with a glass room somebody else put up that leaks or never gets comfortable. If your room is going over a slab you already have, the job works a lot like a patio-to-sunroom conversion. What moves the price is the size of the room, what it sits on, whether we cut a new opening into the house and whether your heating and cooling can carry it or it needs its own unit. The schedule turns on those same things plus the city's permit review, so I give you a written price once I've measured.

What a finished solarium looks like
How we handle a solarium installation
Before we go any further, I figure out whether your current heating and cooling can handle the room or it needs its own unit, because a glass room that's miserable in August or January doesn't get used. Then I check what the room will sit on, whether that's a slab you already have or new footings, since everything above depends on it. When we cut a new opening into the house, we cover your floors and move your furniture out of the way first, so the mess stays on our side of the wall. Our own crew builds the room and ties it into the house, and I make sure water runs off where it should and every door and window closes right. Nothing gets covered up with trim, because I spent years pulling trim off rooms to find what someone was hiding.
A solarium often goes where a patio cover is now, and if shade is all you need for the moment, our patio cover installation is the simpler build. If you aren't sure how big the room should be or where it should open into the house, we can settle that first through sunroom design.
Why Rancho Cucamonga homeowners call us for a solarium
I measure and stay on site
I come out myself to look at your space and measure, and I'm on the job with our own crew when we build. The person who priced your room is the same one checking that it goes together right.
Licensed in California, insured too
California requires a license from the Contractors State License Board for any job worth $1,000 or more in labor and materials combined, and a solarium is well past that. We're licensed and insured, so you aren't hiring someone who works outside that rule.
Building glass rooms since 2017
We've been building these rooms since 2017, and before that I spent years on property upkeep fixing patio covers and enclosures that went up in a hurry. Knowing how the bad ones failed is what I build against.
Rancho Cucamonga based, nearby cities too
We're based in Rancho Cucamonga and work in the cities around it, where a lot of our calls start with a concrete patio or an old patio cover the owner wants closed in. I've seen plenty of those slabs and covers up close, so I know what to look for when I check what your room will sit on.
On a glass room, the heating and cooling plan matters more than anything you'll see, so tell us the size of room you want and how you'll use it and I'll come take a look.
Get a written price for your solarium
Tell us the room size you have in mind and whether it will open into the house. We reply within one business day to set up a free on-site estimate, with no obligation.

What happens after you call about a solarium?
Call or send us a message
Call (909) 360-4006 or use the form, and we'll set a time for me to come out to your house.
I look, measure and price
I look at the space and what the room will sit on, take measurements and ask how you plan to use the room. You get a written estimate, so you know what the job costs before anything gets signed.
We pull permits and build
Once you sign, we take care of the permit when your job needs one and work with the city's building office through the inspections. Our own crew does the building, and I'm there with them.
Walk the finished room together
When the room is done, I walk it with you and we open and close every door and window. That's the time to ask anything about how the room works.
Solarium questions from Rancho Cucamonga homeowners
What counts as a solarium or sunroom?
In the trade, a sunroom is a one-story room attached to a house with glass over more than 40 percent of its outer walls and roof. The most complete kind is fully enclosed, designed to be heated, cooled or both, and open to the main house. If you want the room to work like the rest of your house, plan for that kind and put heating and cooling in the budget.
How much does solarium installation cost in Rancho Cucamonga?
I can't give you an honest number until I've measured, because the price comes from your room and not from a chart. A modest room on a sound slab that runs off your existing heating and cooling sits at the low end, and size, new footings, a new opening cut into the house and a separate heating and cooling unit each push it up. After the visit you get the price in writing.
How do I know if my current heating and cooling can handle a solarium?
One sunroom maker says room size decides whether your existing system can serve the new room, and larger rooms or rooms closed off from the house need vents or a system of their own. In some cases that's a ductless heat pump, a unit that heats and cools without ductwork, so you can keep the room where you like it. If the room counts as an addition, California's Energy Code also sets energy and water efficiency requirements the design has to be planned around.
Do I need a permit for a solarium in Rancho Cucamonga?
Check before you build, because the city's permit list names solar, reroofs and patio covers but doesn't name solariums. Rancho Cucamonga Building & Safety handles permits entirely online, not over the counter, and takes technical permit questions by email at EDRnotification@CityofRC.us. Before we start, we check what the city wants for your address.
How much can a contractor ask for up front on a sunroom in California?
In California, a contractor can ask for or accept a down payment of no more than $1,000 or 10 percent of the total contract price, whichever is less. After that, you pay as the work gets done or as materials arrive, on the schedule the contract lists.
How do I find out if my house is in a fire hazard zone in Rancho Cucamonga?
Look up your address on the city's fire hazard severity zone map, which you can view online or at the city's Fire Headquarters during normal business hours. It's a good step to take while you're still planning the room, before the design is set.
Work that often goes with a solarium installation
Patio cover installation
If shade matters more to you right now than an extra room, a patio cover gets you there with a lighter build.
Sunroom design
Settling the size, layout and opening into the house before you commit keeps the solarium from being built around guesses.
