YOUR LOCAL SUNROOM CONTRACTOR
Trusted Sunroom & Patio Room Contractor Serving Corona Homes
Corona knows wind. When the Santa Anas funnel through the canyon, flimsy backyard structures are the first casualties — which is why every aluminum system we install is engineered to 130 MPH wind ratings and Seismic D standards. Pair that with glazing that blocks up to 85% of solar heat, and you get a room that's calm and comfortable while the weather does whatever it wants outside.
For the thousands of Corona residents who spent years on the 91 and now work from home, a sunroom is the office upgrade the spare bedroom never was: separate, quiet, and full of daylight. We run the entire project — free in-home design quote, site check, engineering, City of Corona permits, and installation by factory-trained crews — and with C-Thru's factory in neighboring Riverside, your room doesn't spend weeks on a truck.

- Aluminum systems engineered to 130 MPH wind / Seismic D

WHAT WE BUILD
Custom Sunrooms & Patio Enclosures in Corona
Glass rooms for year-round living, enclosed patios on the slab you already own, and patio covers that stand up to canyon winds — engineered for Corona conditions.
Four-Season Sunrooms
Insulated glass rooms with CONSERVAGLASS NXT — bright in January, cool in August, and sealed tight against the dust the canyon winds carry.
Three-Season Patio Rooms
Turn your covered patio into a real room. For newer South Corona homes, it's the fastest way to add the bonus room the floor plan skipped.
Solid-Roof Patio Enclosures
Insulated EPS roof panels with C-Thru Alpha and Omega wall systems — built one town over in Riverside, engineered for Inland Empire weather.
Screen Rooms
DuraScreen enclosures that hold up in gusty weather and keep the evenings on the patio going — without bugs or windblown debris on the furniture.
Aluminum Patio Covers
Duralum Weatherwood solid and lattice covers in 8 woodgrain colors. The 130 MPH wind rating isn't marketing here — in Corona it's a requirement.
Conversions & Upgrades
Convert an existing patio cover into a full patio room, replace a wind-damaged cover with engineered aluminum, or upgrade an older enclosure.
WHY HOMEOWNERS HIRE US IN CORONA
We Build for Corona Conditions
Canyon winds, hot summers, and neighborhoods that range from century-old streets to brand-new tracts. Here's what that takes.
Wind-Rated Engineering
Every Duralum system we install carries a 130 MPH wind rating and Seismic D engineering. When the Santa Anas come through the canyon, your room and cover stay put — and stay quiet.
Corona Permit Experience
Plan submittals, building permits, and inspections with the City of Corona, handled in-house from start to finish. HOA paperwork for communities like Eagle Glen and Dos Lagos? Also us.
The Home-Office Upgrade
Working from home after years on the 91 deserves better than a corner of the dining table. A daylight-filled, permitted sunroom office is the room remote work actually calls for.
Factory One Town Over
C-Thru manufactures in Riverside, minutes from Corona — factory-direct lead times and fast parts. Duralum builds in Sacramento and Four Seasons manufactures in California, so every line is state-made.
OUR PROCESS
From Free Quote to Finished Room
One point of contact from the first phone call to the final city inspection — here's how it goes.
Free In-Home Consultation
A design consultant comes to your Corona home, measures the space, checks wind exposure and sun angles, and tells you straight what will and won't work — no obligation.
Design & Product Selection
Pick the line and options that fit — Four Seasons, C-Thru, or Duralum; glass, frames, doors — and walk away with a firm, line-item price.
Site Check, Engineering & Permits
We confirm your slab and footings, run the wind-load engineering, and pull your City of Corona permits in-house.
Professional Installation
Factory-trained crews assemble your pre-engineered room in days to a few weeks on site — most projects wrap within a few months of signing.
Final Inspection & Warranty
City final inspection, a full walkthrough of your new room, and your transferable lifetime manufacturer warranty registered in your name.
CORONA SUNROOM FAQs
Common Questions From Corona Homeowners
Ours can — it's what they're engineered for. Duralum's aluminum systems are rated to 130 MPH wind and Seismic D standards, with engineering calcs the City of Corona reviews as part of your permit. If you've lost a wood or bargain-aluminum cover to the canyon winds before, this is the replacement that ends the cycle.
Budget $15,000-$25,000 for a three-season patio room on an existing slab, and $30,000-$70,000+ for a fully insulated four-season sunroom with premium glass. A comparable stick-built addition typically costs two to three times more. Your free in-home quote breaks the whole number down line by line.
Yes — sunrooms, patio rooms, and most patio covers need a City of Corona building permit, and the wind-load engineering matters here more than most cities. We prepare and submit everything, schedule the inspections, and handle HOA architectural paperwork where your community requires it.
A few months from signed contract to final inspection, most of it permitting and engineering. The build itself moves fast — pre-engineered rooms go up in days to a few weeks, and with C-Thru manufacturing in neighboring Riverside, material lead times stay short.
It's arguably the best one. You get a dedicated, permitted room flooded with natural light, separated from household noise, with its own entrance to the backyard. Add a mini-split and CONSERVAGLASS NXT glazing and it holds a working temperature year-round — video-call ready in February and July alike.
A patio room (or patio enclosure) is usually built on your existing patio slab for three-season use. A four-season sunroom is fully insulated and can tie into your home's heating and cooling for year-round comfort. We build both and we'll recommend the right fit at your free quote.
Three California-made lines: C-Thru Sunrooms (built in Riverside, one town over), Four Seasons Sunrooms with CONSERVAGLASS NXT glazing, and Duralum (Sacramento). Each carries a transferable lifetime warranty that follows the house, not just you.
Yes. We have financing options available, and plenty of Corona homeowners pair the project with a HELOC instead. Bring the question to your free in-home quote and your consultant will lay out the choices.
