Sunroom additions in Norco CA - a room built for how you'll really use it
Patio too hot, too buggy or too bare to use? We add a sunroom planned around how you'll actually spend time in it.

What goes into a sunroom addition in Norco?
A sunroom addition is a new room built onto your house, with a roof, a floor and walls of glass tied into the house. We build sunroom additions in Norco so the patio or corner of yard you never use becomes a room you sit in.
Most people who call me have a patio that's too hot by noon, or a deck or old enclosure that's past fixing. If you already have a patio you'd like to close in, that's often a patio-to-sunroom conversion, and I'll tell you on site whether it makes sense. The size of the room, whether it needs new footings under it and whether it's heated and cooled move the price most. The schedule mostly turns on how fast those choices get settled, because nothing gets ordered until they are. Your written estimate spells out what's included and what isn't for your room.
What our sunroom additions include
The first thing I ask is whether the room gets heating and cooling, and whether the AC you have now can handle the extra space, because we sort that out with you before anything gets drawn. Then we design the room around your house, set the footings, frame it, flash and seal where it meets your wall so water stays out, put the roof on, run the electrical and lay the floor. That's a lot of trades in one room, so I'd rather our crew carry it from the ground up than piece it out to strangers.
Most additions end up as one of two rooms, four season sunrooms or three season sunrooms, and that choice comes first because it decides the windows, the insulation and whether the AC question matters at all. I'll tell you straight which one fits the way you described using the space.
Planning a sunroom addition in Norco
Before we draw anything, look up your address on the State Fire Marshal's fire hazard map to see which Fire Hazard Severity Zone your property sits in. If your property falls in a Local Responsibility Area, the state sends you to your local jurisdiction, so that's who you'd ask. It takes a few minutes, and it means we're planning with that answer in hand.
A lot of Norco calls start with an existing patio slab, often one poured bigger than the room you want, so we check its size and condition before deciding whether to build on it or put in new footings. We see the same setups on jobs in Corona and Eastvale, along with the same summer heat that makes the AC question the first one I ask.
How a sunroom addition works
Call or send the form
Call (951) 393-1005 or use the form, and we'll set a time for me to come to your house. We pick up weekdays from 6 AM to 11 PM and weekends from 8 AM to 9 PM.
I come out and measure
I look at the spot, measure and ask how you plan to use the room, because that decides the room type and whether your AC has to carry it. It helps to know when you'd sit in it, mornings, summer afternoons or evenings.
You get a written estimate
It lists what's included and what isn't, so you can see where the money goes and compare it with anyone else's. If the job needs a permit, we put the application together, deal with your city or county building office and set up the inspections.
Our crew builds the room
Our own crew handles the build from footings to floor. When it's finished, I walk the room with you before we call it done.

Get a written estimate for your sunroom addition
We respond within 1 business day, and the on-site estimate is free, with no pressure and no obligation. After you send the form, we call to set a time for me to come out, look at the spot and measure.
Questions before you add a sunroom
How much does a sunroom addition cost in Norco?
A sunroom in the Riverside area usually costs about $17,000 to $120,000 per project, according to a local cost guide. Larger rooms that need a foundation and get heating and air conditioning sit at the high end. That's the area's range, not our price, and your written estimate gives you the number for your room.
What is the difference between a four season and a three season sunroom?
A four season room is fully enclosed, heated and cooled, while a three season room has no heating or cooling and uses uninsulated windows or screens. So the real choice is a room you can use in any month or an enclosed porch for milder weather. That's how sunroom makers and builders describe the two across the country, and it holds here too.
How do I know if my AC can handle a new sunroom?
Ask before the room is designed, because most central systems are sized for the house as it was first built, and a sunroom can push yours past what it can handle. When that happens, the whole house runs warmer, not just the new room. If the answer is no, we plan for it now instead of finding out in July.
Should I insulate a sunroom when it's built or add it later?
Insulate it when it's built. Insulated windows, walls, floor and roof are much easier to put in during the build, and adding them later can often cost more. If you want an energy efficient room, those choices get settled before work starts.
What causes a damp spot on a sunroom floor in wet weather?
On a slab that's bigger than the room, the room's floor channel is sealed straight to the concrete, and a damp spot can show inside when it's wet out. One sunroom maker says the spot goes away with the wet weather and isn't a structural problem. If we're building on your existing slab, I'll point this out before you decide.
Does it matter who installs my sunroom for the warranty?
Yes, because one maker gives no labor warranty to owners who install the room themselves or arrange their own installer, and many factory warranties depend on proper installation. Those are a maker's terms, so read the warranty on the room you pick. Our own crew does the build, so you know who installed it.
Why Norco homeowners call Suncrest Norco Sunrooms & Patios for sunroom additions
I measure every job myself
I come out to look at the spot, measure and ask how you'll use the room, whether it's a slab off the kitchen or a corner of a big Norco lot. That way the room gets drawn for your house and your habits, and if what you asked for won't work, I'll say so.
Our own crew builds it
The people framing, roofing and finishing your sunroom work for us, not for whoever was free that week. You know who's at your house, and I answer for every part of the job.
In business since 2017
I learned the trade on a sunroom and patio crew and have run this business since 2017. Nine years in, what people know us for is a straight answer, even when that answer is a smaller room or a different one.
Licensed and fully insured
We're licensed and fully insured on every sunroom we build. Ask about it at the estimate, and I'll answer before you sign anything.
A room you'll actually sit in starts with getting the room type and the AC question right before anything is drawn, so tell us about your spot or call (951) 393-1005.
Other sunroom work you might need
Four season sunrooms
Pick this if you want a room you can sit in through a Norco summer afternoon and a cold January night, with heating and cooling built in.
Three season sunrooms
A good fit if you mostly want shade and a place out of the bugs in spring and fall, without adding to the load on your AC.
Tell us where your sunroom will go
