Outdoor Living Spaces
YOUR LOCAL SUNROOM CONTRACTOR
Trusted Sunroom & Patio Room Contractor Serving Anaheim Homes
A sunroom or patio room is the fastest way to gain a bright, usable living space — a breakfast room, home office, gym, or entertainment area — typically at 50-70% less than the cost of a conventional addition. In Anaheim, that new room has to stand up to 90°+ inland summers and Santa Ana wind events, and in many neighborhoods it has to clear an HOA review too. We engineer for all of it.
We're a true concept-to-completion contractor. One of our designers comes to your Anaheim home for a free in-home quote, we run the site check, handle engineering and City of Anaheim permits, and our factory-trained crews handle the installation. Our showroom in Buena Park is just minutes away, so you can see and touch the rooms before you buy.

WHAT WE BUILD
Custom Sunrooms & Patio Enclosures in Anaheim
Whether you want a fully insulated glass room you can use year-round, an enclosed patio room on your existing slab, or a patio cover to tame the afternoon sun — we design and build it from scratch.
Four-Season Sunrooms
Fully insulated glass sunrooms built for year-round comfort. CONSERVAGLASS NXT glazing blocks up to 85% of solar heat and 90% of UV rays, so the room stays usable even in Anaheim's hottest months.
Three-Season Patio Rooms
Budget-friendly enclosed patio rooms that convert your existing covered patio into a real room — perfect for spring evenings, fall mornings, and everything in between.
Solid-Roof Patio Enclosures
Insulated EPS roof panels with C-Thru Alpha and Omega wall systems. A cooler, quieter enclosed patio that feels like part of the house.
Screen Rooms
DuraScreen and screened patio enclosures that give you airflow and indoor-outdoor living without the bugs — a favorite for Anaheim backyards near the riverbed and parks.
Aluminum Patio Covers
Duralum Weatherwood solid and lattice covers in 8 woodgrain colors — engineered to 130 MPH wind ratings, so Santa Ana winds aren't a problem.
Conversions & Upgrades
Already have a patio cover? We can convert it into a full patio room, or upgrade glass, doors, screens, and electrical in an existing enclosure.
WHY HOMEOWNERS HIRE US IN ANAHEIM
We Know Anaheim Homes
From mid-century ranch homes in the Colony to hillside lots in Anaheim Hills, every neighborhood brings its own permitting, HOA, and engineering wrinkles. Here's how we handle them.
Anaheim Permit Experience
We handle plan submittals and building permits with the City of Anaheim from start to finish — including the HOA architectural paperwork common in Anaheim Hills communities. You won't make a single trip to City Hall.
Built for Inland Heat & Wind
Anaheim summers regularly top 90°, and Santa Ana winds are no joke. We spec high-performance glass that blocks up to 85% of solar heat and aluminum systems engineered to 130 MPH wind and Seismic D standards.
California-Made Product Lines
Every room we install is built in California — C-Thru in Riverside, Duralum in Sacramento, and Four Seasons at its California manufacturing plant. That means shorter lead times, readily available parts, and rooms designed for California building codes from day one.
Showroom Minutes Away
Our Buena Park showroom is about 10 minutes from most of Anaheim. Walk through full-size sunrooms and patio rooms before you decide — then get a free in-home quote at your house.
OUR PROCESS
From Free Quote to Finished Room
A clear, simple process with one point of contact from your first call to your final city inspection.
Free In-Home Consultation
One of our design consultants visits your Anaheim home, measures your patio or yard, talks through how you'll use the space, and gives honest feedback on what's possible — no pressure, no obligation.
Design & Product Selection
We help you choose the right product line — Four Seasons, C-Thru, or Duralum — plus glass, frame colors, doors, and electrical options. You get a firm, line-item quote with no surprise allowances.
Site Check, Engineering & Permits
We verify your slab, footings, and site conditions, then handle all engineering and City of Anaheim permitting in-house — including HOA submittals where required.
Professional Installation
Factory-trained crews install your room. Because these are pre-engineered systems, on-site installation usually takes days to a few weeks — most full projects wrap up within a few months of signing, permits included.
Final Inspection & Warranty
We coordinate the final city inspection, walk you through the finished room, and register your transferable lifetime manufacturer warranty.
ANAHEIM SUNROOM FAQs
Common Questions From Anaheim Homeowners
Most Anaheim sunroom and patio room projects run between $15,000 and $70,000+ depending on size, glass, and insulation level. A basic three-season patio room starts around $15,000-$25,000, while a fully insulated four-season sunroom with premium glass runs $30,000-$70,000+. That's typically 50-70% less than a traditional room addition. We give you exact, line-item pricing at your free in-home consultation.
Yes. The City of Anaheim requires a building permit for sunrooms, patio rooms, and most patio covers. Premium Sunroom Construction handles all engineering, plan submittals, permits, and inspections for you — and if you live in an HOA community like many in Anaheim Hills, we prepare the architectural approval paperwork too.
Plan on a few months from contract to completed room, with most of that being design, engineering, and city permitting. The on-site installation itself is fast — because our rooms are pre-engineered modular systems, crews are typically on your property for days to a few weeks, not months.
The terms overlap a lot. A patio room (or patio enclosure) is usually built on your existing patio slab, often under an existing or new solid roof, and is designed for three-season use. A sunroom — especially a four-season sunroom — is a fully insulated glass room that can tie into your home's heating and cooling for year-round comfort. We build both, and we'll help you pick the right one for your budget and how you plan to use the space.
We're an authorized dealer for three of the most established names in the industry: Four Seasons Sunrooms (with CONSERVAGLASS NXT high-performance glazing), C-Thru Sunrooms (manufactured in Riverside, CA — Alpha and Omega wall systems), and Duralum (Sacramento, CA — Weatherwood patio covers and Duralife sunrooms). Every line carries a transferable lifetime warranty.
Yes — if it's built for it. Our four-season rooms use insulated wall panels and CONSERVAGLASS NXT glass that blocks up to 85% of solar heat and 90% of UV rays, which keeps the room comfortable through Anaheim's hot summers. Add a mini-split or tie into your HVAC and the room is usable 365 days a year.
A professionally built, permitted sunroom adds usable square footage and is a strong selling point in the Orange County market. Because all three of our product lines carry transferable lifetime warranties, the coverage passes to the next owner — something buyers and agents notice.
Yes — financing options are available, and many Anaheim homeowners also use home equity lines to fund their project. Ask your design consultant during your free in-home quote and we'll walk you through the options.
