Sunroom Contractor in Corona, CA - Patios and Decks Turned Into Rooms You Use
Comfortview Corona Sunrooms & Patios is a sunroom contractor based in Corona, CA. We turn backyard patios, decks and patio covers into sunrooms, screen rooms and enclosed patio rooms that homeowners here can use for more of the year.
Corona as we see it from the backyard
Corona is home for us. I started the business here in 2023 after learning the trade on a crew building patio covers and sunrooms around Riverside County, and we do the same work in nearby Jurupa Valley and Norco.
On jobs here we see older neighborhoods and newer tracts, mostly single-family houses with a backyard patio that doesn't get as much use as the family hoped. Some already have an aluminum or wood patio cover, some have a raised deck, and a few have an older sunroom that's ready for new glass or a new roof. What's already there decides most of the plan, because the slab, the deck framing and the wall we tie into all have to carry the room for as long as you live with it.
Services in Corona, CA
Sunroom additions
Plenty of Corona homes have a back wall that opens onto an empty patio, and sunroom additions give that wall a real room with a roof tied into the house. We plan the footings and the roof joint first, because those decide whether the room stays solid and dry.
Patio-to-sunroom conversion
When you already have a concrete patio, we check its thickness and condition before we put walls on it. If it can carry the room, we build there, and if it can't, we explain what it needs before we price anything.
Patio enclosures
Many backyards here already have a patio cover for shade, and enclosing it with windows or screens can make it usable for more of the year. We look at whether the posts and beam can take the added weight before we suggest it.
Screen room installation
Some homeowners want the open-air feel of the patio without the bugs, and a screen room keeps the air moving while keeping insects out. We frame it to fit the space you already have, with a door that closes tight.
Deck-to-sunroom conversion
A raised deck out back is a good start for a room, but a deck built for patio furniture usually needs more support before it can carry walls and a roof. We open it up, check the framing and footings, and tell you plainly what we found.
Sunroom remodeling
Older sunrooms and patio rooms around Corona often show their age in fogged glass, worn seals or a leak where the roof meets the house. We'd suggest fixing the seal and the roof tie-in first, since new finishes won't last over a leak.
Working in Corona: permits, licenses and what moves the price
Whether your sunroom needs a permit is up to the City of Corona's building office, not us, so we don't put a build date on the calendar until we know what that office expects for your address. Before you sign with anyone, you can check two things. Look up the contractor's state license with the Contractors State License Board, and ask whether they hold a City of Corona business license, which the city requires of every business working here.
We're licensed and insured, and when your job calls for a permit, we prepare the paperwork and work through the process with you. The price moves with the room type, from a screen room up to a fully glassed four season room, along with its size, the glass and how much work the slab, deck or cover needs before it can carry the room, while the schedule mostly turns on the permit and the inspections. Building offices differ from one city to the next, so a job just over the line in Riverside gets its own check rather than a copy of Corona's steps.
What Corona backyards tell us before we plan a room
Most calls we get in Corona start with something already built, like a concrete patio, a raised deck or a patio cover the family likes but rarely sits under. A room is only as good as what it sits on and how well it's sealed, so I'd rather take a second look at that slab or those posts than rush a plan, and if they can't carry walls and glass, we explain the fix before we price it. We also look closely at where the new roof will meet your house, because that joint is where a room either stays dry or doesn't.
Some properties in Corona also fall under the city's construction requirements for fire hazard severity zones. If those apply to your address, they shape how the room has to be built, so we find out before the plan is drawn.

I visit and take measurements
I look at the space, measure it and check what the room would sit on, whether that's a slab, a deck or an existing cover. It helps if you've thought about how you'd use the room, for meals, a home office or just sitting out.
Review your written estimate
You get a written estimate showing the room type, materials and what's included. We go over each option and its tradeoff so you know what you're paying for before you agree to anything.
We check the building office's requirements
Before the job is scheduled, we check what the city's building office expects for your address and prepare the permit paperwork when it's needed. Corona City Hall is open Monday through Thursday, 7 AM to 6 PM, and closed Fridays, so any in-person permit visit falls on those days.
We build, inspect and walk through
Our installers and I build the room together, and since the city schedules inspections Monday through Thursday, we plan each stage around those days. Before we call it complete, I walk through the finished room with you.
Sunroom questions from Corona homeowners
How do I get a building permit for a sunroom in Corona?
Building permits in Corona go through the City's Planning & Development department, which handles building, electrical, mechanical and plumbing permits, and its permit line is 951-736-2250. The city also runs an online permit and project portal for applicants.
Does a contractor based outside Corona need a Corona business license?
Yes, the City of Corona requires a business license for every business working in the city, including contractors whose main address is somewhere else. The license renews every year, so it's fair to ask a contractor from a neighboring city whether theirs is current.
When does a sunroom contractor need a California state license?
A contractor needs a California license whenever the job needs a building permit, uses any hired workers, or comes to $1,000 or more in labor and materials. That small-job limit used to be $500 and is now $1,000, and it only covers work with no permit and no hired workers, so nearly any sunroom job falls outside it.
Which building code does Corona use for sunrooms?
Corona has adopted the 2025 edition of the California Building Standards Code, through an ordinance the city council passed in November 2025. We plan your room around what the building office will review it against, not around an older set of plans.
How much does a sunroom cost in Corona?
Your price comes from a written estimate after I've seen the space, because the biggest factors are the room type, its size, the glass or screen and how the roof ties into your house. What's already there matters too, since a slab, deck or cover that can carry new walls costs less to build on than one we have to reinforce or replace.
What is the best way to turn a patio cover into a sunroom in Corona?
Start by having the cover and the slab under it checked, because a cover built for shade often wasn't built to carry walls, windows and a sealed roof. Sometimes the posts and beam can stay and we build around them, and sometimes a new roof is the cleaner choice, and we'll tell you which we'd suggest and why at the estimate.
