What is an enclosed patio room, and should mine be heated?
An enclosed patio room, which the sunroom trade calls a patio enclosure, is a sunroom built over a patio slab or deck you already have. For Seal Beach homeowners it turns a spot you dodge on windy or buggy evenings into a room with walls, windows and a roof.
Most people who call me have a patio they like but hardly use, because the wind, the bugs or the afternoon sun chase them back inside. The biggest thing that moves the price is whether you want the room heated. One maker says four-season rooms are generally much more expensive than three-season rooms because they're a deeper change to the house, and that they may need extra permits, which we find out about and pull for you. Larger rooms that need a foundation plus heating and air conditioning land at the high end, and the schedule mostly turns on the design you settle on and the permits it calls for. Your written estimate puts your own number on it.
How we build an enclosed patio room
I start every patio room by laying out a simple unheated option next to a heated one, so you can compare comfort and cost side by side before you commit to either. That's also the time to decide on insulation, because 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 often costs more. Once you've picked, we check that your slab or deck can carry the room, frame the walls and roof, tie the room into the house, seal the joints where new meets old, set the windows or screens and clean up.
Some patios call for a different job. If you want glass overhead and walls that are mostly windows, solarium installation is the closer fit, and if shade and a dry spot are all you're after, patio cover installation gets you there with less work.
Unheated patio room
This suits you if you want the patio for evenings and weekends with the wind and bugs kept out, and you're fine stepping back inside on the coldest nights. It's the simpler, lighter build, and we plan openings so the room can breathe.
Heated four-season room
This suits you if you want a real room you'll use every day, often open to the kitchen or living room. It costs more and asks more of the build, so it's worth choosing at the start rather than adding later.
Building enclosed patio rooms in Seal Beach's salt air
Salt air is the local factor that changes how I build a patio room here. Near the shoreline we use frames that resist corrosion with stainless fasteners, and we look harder at covered spots, because one supplier notes that areas under overhangs, covered decks and screened enclosures tend to corrode faster where rain can't rinse the salt off. A patio room is full of those spots, so that's where the hardware and sealing get our closest look. We see the same air on jobs in Huntington Beach and Long Beach.
The other thing I meet on most jobs is a house that's been lived in a while, with stucco walls and a slab poured long before anyone planned a room on it. I check both before I draw anything, since how the room meets that wall and sits on that slab matters more than anything you'll see. We're based in Seal Beach and work across the cities around it.
Why Seal Beach homeowners call Seal Beach Sunrooms & Patios for patio rooms
The owner estimates and builds
I give the estimate and then work alongside our crew on the build, so the person who sketched your room is on site while it goes up. Details like where the room meets your stucco don't get lost between a salesperson and a crew.
Adding onto houses since 2020
We've been building rooms onto lived-in houses since 2020, and I spent the years before that framing new ones. That taught me the hard part is the joint between old and new, so that's where I spend the most time.
Licensed, insured, and easy to check
We're fully licensed and insured. When you compare bids, ask each contractor which license class they hold for enclosure work, since the state's contractor board says its awning license covers patio covers but not patio enclosures.
The choice between heated and unheated is easier to make standing on your own patio than reading about it, so call (562) 200-7987 or send us a note and I'll come take a look.

What happens after you call about a patio room?
Walk your patio with me
After you call or send the form, I come out to look at your house, the patio or deck and how you want to use the room, and sketch the options with you right there. Your written estimate lays out each option you're weighing and what it includes, so the cost isn't a guess.
Permits, then the build
Once you pick an option, we line up the permits and inspections the job calls for, so you're not chasing paperwork. Then our crew and I build the room, starting with how it ties into your house.
Walk the finished room together
When it's done, I walk the room with you and point out anything that needs your attention. I also show you how to look after the windows, seals and frame.
Frequently asked questions
What is the difference between a three-season and a four-season patio room?
A four-season room is fully enclosed, heated and cooled, with all-weather windows, while a three-season room or enclosed patio usually has no heating or cooling and uses uninsulated windows or screens. Which one suits you comes down to whether you want the room on cold nights and hot afternoons or mostly on mild days.
How much does an enclosed patio room cost in Orange County?
Going by 2024 figures, sunroom construction in Orange County usually costs about $17,000 to $120,000 per project. That range covers sunrooms in general, not patio rooms alone, and heated rooms on a new foundation sit toward the top for the reasons above. Your free written estimate gives you the number for your own patio.
Which materials hold up best near the shoreline in Seal Beach?
Aluminum and composite hold up better than standard steel or untreated wood near the shore, according to one coastal supplier. It adds that they still depend on the right hardware, with stainless steel fasteners keeping the connections strong, which matches how we build near the water.
How do I find out what flood zone my Seal Beach house is in?
Look up your street address on the FEMA Map Service Center, which is where Orange County's flood program sends owners. The quick map it shows first is not an official flood map. I'd rather know your zone before we plan the floor, so bring it to the estimate if you have it.
What causes an enclosed patio room to get too hot in summer?
An enclosed room stores heat in summer, and one maker notes it can get quite uncomfortable when its panels can't open enough or air can't move through. That's why I plan where the openings go as carefully as where the glass goes.
Does a heated patio room open to the house count as living space?
Yes, the sunroom industry's standard treats an enclosed room that's heated or cooled and open to the main house as habitable living space. Its windows have to meet that standard's requirements for air leaks, water getting in and how well they hold heat. If you want the room open to your kitchen or living room, I'll plan the windows for that from the start.
