Vinyl sunrooms in North Tustin CA - a bright room built the way it was planned
Your patio gets too much sun, wind or bugs to enjoy. We enclose it in vinyl frames and the right glass so you actually use it.

Is a vinyl sunroom the right fit for your North Tustin patio?
Vinyl sunrooms in North Tustin, CA enclose a patio or porch with PVC-framed windows, walls and a roof. You get a room out of the wind and bugs that you can use more of the year, built either as a three-season room or as a four-season room you heat and cool.
Most people who call us have a patio that's too hot to sit on in the afternoon, or a porch they'd like to use past summer. The price moves mostly with the room's size, whether it's a three-season room or one you heat and cool, whether it needs its own foundation, and how much insulation and glass goes in. The schedule turns on settling those choices and on the permit review for your address, and your estimate spells out each piece so the number you see matches the room we'd build. We're licensed and fully insured, and that license comes from California's Contractors State License Board, which licenses and regulates the state's construction industry.
What happens after you call about a vinyl sunroom?
Call or send us a message
Call (657) 356-0209 or use the form, and we'll set a time for me to come out. Give us your address up front, because we look up which office reviews permits there.
I measure and plan the room
I measure the space, look at the slab, deck or wall the room will tie into, and ask how you plan to use it. You get a written estimate that lists the room type, windows, roof and base, so you can see what each choice costs before anything is ordered.
We handle permits and build
Once you're ready, we take care of the permit applications and inspections, and our own crew builds the room, led by an experienced installer. I check in as the job goes so what goes up matches what's on paper.
We walk the finished room
Before we call it done, I walk through the room with you and compare it to the written plan, down to the windows and roof panels. The work is backed by our satisfaction guarantee.
How we build a vinyl sunroom
We start with how you'll use the room, because that decides whether it's a three-season or four-season build and what goes into the walls. We like vinyl frames because they pass much less heat than metal frames, about the way wood does, and they clean up easily. If there's any chance you'll want the room year-round, we settle insulated windows, walls, floor and roof in the plan, since they're much easier to put in during the build and adding them later can often cost more. Then our crew preps the slab, deck or wall the room ties into, sets the vinyl frames and the glass we picked together, puts on the roof panels and seals everything to the house, building to the written estimate so the room matches what you agreed to.
If there's no patio to build on, or the room needs its own foundation, the job becomes one of our sunroom additions, where we build the base and tie the roof into the house. When you want to sit out there in August and January alike, our four season sunrooms cover the insulated, heated and cooled version in more detail.

Vinyl sunroom questions from North Tustin
How much does a sunroom cost in Orange County?
A sunroom in Orange County usually costs about $120 to $200 per square foot, and that range covers sunrooms of every type, not vinyl ones alone. Larger rooms that need a foundation and come with heating and air conditioning sit toward the top of it, while a smaller three-season room on an existing patio usually lands lower. Your written estimate lists the room type, windows, roof and base, so you can see which choices set your number.
What is the difference between a three-season and a four-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. That's how the terms are generally used around the country, and the choice shapes your budget. I'll lay out both at the estimate, and if a simpler three-season room fits how you'll actually use the space, I'll tell you so.
Who handles building permits for a sunroom in North Tustin?
Orange County handles building permits in the county's unincorporated areas. Its list of typical permit projects names building additions and patios but doesn't name sunrooms, so whether your room needs one is a question for the county, not something to guess at. We look up which office reviews your address, then handle the permit applications and inspections for the work we do.
How do I plan a sunroom if my North Tustin home is in a fire hazard zone?
Plan around the fire rules from the start, because buildings constructed in a Very High Fire Hazard Severity Zone are required to use fire-resistive features from California's building codes for exterior wildfire exposure. The county's fire hazard map for unincorporated areas sorts places into Very High, High and Moderate zones. We check your address against that map and against the county's North Tustin Specific Plan before the room is drawn, since either can shape the materials and layout.
How much can a contractor ask for as a down payment in California?
On a California home improvement job, a contractor can't ask for or accept a down payment of more than $1,000 or 10 percent of the total price, whichever is less. Later payments have to be listed in the contract and match work done or materials delivered, so it's worth reading that part before you sign.
What is the best way to keep a vinyl sunroom cool in summer?
Glass choice does most of the work, and the California Energy Commission notes that cooling climates generally benefit from a low SHGC coating, one that lets in less of the sun's heat. Heating climates may do better with a high SHGC coating instead, so we look at which way the room faces and how you'll use it before choosing. California's Energy Code also sets efficiency requirements for additions, not only new houses, and it's a fair question to ask any installer, us included, how the room meets them.
Other work that often goes with a vinyl sunroom

When the yard has no slab or deck to build on, an addition gives the new room its own base and a roof tied into the house.
