Custom sunrooms in Norco CA - a room sized and insulated for how you'll use it
Got a patio or deck you barely use? We build a sunroom sized, insulated and finished for the way you'll spend time in it.

What does a custom sunroom in Norco involve?
A custom sunroom in Norco is an enclosed room with windows or screens added onto your house and planned around how you'll use it, from a screened room for mild evenings to a heated and cooled room you can sit in all year.
Most people who call me have a patio, a deck or a tired old enclosure that isn't getting used, and some are ready for a full patio-to-sunroom conversion. The price mostly comes down to size, whether the room needs its own foundation and whether it's heated and cooled, while the schedule mostly turns on the permit and inspections, and the written estimate you get from me spells out what's included and what isn't.
How we build a custom sunroom
I start every custom sunroom with one question, which is how you want to use the room, and then we pick the type, size and insulation to match. If a smaller room does the job, I'll tell you, because I won't push the biggest version just to make the job bigger. We settle the insulation during design, since insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is going up, and adding them later can often cost more. For a heated or cooled room we also decide how it ties into your house, because keeping your existing doors and windows in place seals the room off from the home, and a national sunroom trade group's guide says a room that isn't sealed off follows the same model energy code rules as any other addition. Then our crew builds it the way we planned it.
If you already know the room you want and just need it built, that's our sunroom construction work. If you've got an older enclosure that leaks or sits empty, sunroom remodeling can make more sense than tearing it out and starting over.
Custom sunrooms in Norco and the city's fire zone rules
The City of Norco says a project here will most likely need a building permit, so we plan on one for a custom sunroom from the first visit. The state fire marshal has put out recommended fire hazard maps for Riverside County, which takes in Norco, and the city says homes in a High Fire Hazard Severity Zone have to meet home hardening rules to cut ignition risk, with new construction and renovations there following wildland-urban interface, or WUI, building codes. A sunroom is new construction, so if the city's fire hazard zone maps put your lot in one of those zones, those codes shape what the room is built from, and I check that before the design is final.
Around here, what I see most is a patio or deck that takes hard afternoon sun and sits empty because of it. We're based in Norco and build all over the cities around it, and the same backyards and the same question about heating and cooling come up on jobs in Corona and Eastvale.
How a custom sunroom gets built
Call and set a visit
You call (951) 393-1005 or send the form, and we set a time that works for you. I come out myself to look at the spot, measure and ask how you plan to use the room.
Get your written estimate
You get a written estimate that says what's included and what isn't. That way you can see where the money goes and hold it up against any other bid.
We handle the permit side
If the job needs a permit, we put the application together, deal with your city or county building office and set up the inspections. The start date follows the city's review, so we schedule the build around it.
Build and walk the room
Our own crew does the build, with the inspections set along the way. When it's finished, I walk the room with you before we call it done.

Get a custom sunroom estimate at your place
We respond within 1 business day, and the on-site estimate is free with no pressure and no obligation. Once you send the form, we set a time, I come out to measure and talk through how you'll use the room, and then you get a written estimate that says what's included and what isn't.
Questions before you book a custom sunroom
What is the best way to choose between a three-season and a four-season sunroom?
Decide whether you want the room heated and cooled, because that's the real difference between them. A four-season room has heating, cooling and all-weather windows, a three-season room has neither and uses uninsulated windows or screens, and a screened porch is screens only with no windows or temperature control. If you want to sit out there in August or January, go four-season.
How much does a custom sunroom cost near Norco, CA?
A sunroom project in nearby Riverside usually costs about $17,000 to $120,000 per job, which is the going range in the area, not our price. Larger rooms that need a foundation and have heating and air conditioning land at the high end, and smaller rooms without them sit lower. Your own number comes from the written estimate after I measure.
Can you build a sunroom on top of my existing deck?
Yes, a sunroom can go on a deck, though the deck will typically need added beams, posts or footings to carry the new room's weight. I look underneath when I measure so that work shows up in the estimate instead of halfway through the build, and our deck-to-sunroom conversion page covers it in more detail.
Do I need a licensed contractor to build a sunroom in California?
Yes, because California's license board only lets unlicensed people take jobs up to $1,000, and only when the work needs no permit and they employ no one. A sunroom runs far past that and will most likely need a permit in Norco, so ask for a license before you sign anything.
How much can a contractor ask for as a down payment in California?
No more than $1,000 or 10 percent of the contract price, whichever is less, and the state allows no exception for special-order materials. The board also says a home improvement contract has to say in writing who will get the permits and give a completion date, so look for both before you sign.
How do I take care of a sunroom once it's built?
Have the roof and gutters looked over once a year, which is what one sunroom maker's construction guide suggests. Clear leaves out of the gutters when they build up too, since backed-up water is usually what finds its way in.
Why Norco homeowners call Suncrest Norco Sunrooms & Patios for custom sunrooms
I measure your space myself
The person who comes out, measures and asks how you'll use the room is me, and our own crew does the build. The plan you sign is built on what I saw in your backyard, not on a sales sheet.
In business since 2017
We've been building sunrooms and patios since 2017, and we're based in Norco, so the city's fire zone rules for new construction are part of how we plan a room here. That keeps you from a design that has to change after the city weighs in.
Licensed and fully insured, every job
We're licensed and fully insured. That protects you if something goes wrong on your property while the room is going up.
Satisfaction guaranteed on every job
Satisfaction guaranteed on every job is the promise we make. I'd rather talk you out of the wrong room up front than build something you won't sit in.
A sunroom only pays off if you use it, and that starts with how you plan to spend time in it. Tell us about your space or call (951) 393-1005, and I'll come out and measure.
