What is a vinyl sunroom, and which kind fits your patio?

A vinyl sunroom in Fountain Valley, CA closes in your patio or porch so you can use it more of the year. It can be anything from a screened space that keeps the bugs out to a fully enclosed room with all-weather windows.

We're Fountain Valley Sunrooms & Patios. We're based in Fountain Valley and work in many cities around it. Most people who call us have a patio that's too hot, too buggy or too dusty to enjoy, and they want a room they'll actually sit in. Before I talk about size, I'll ask whether you plan to heat and cool the room, because that one answer decides the windows, the insulation and the paperwork the city will want. The price moves mostly with the size of the room, the kind of windows and whether it's heated and cooled. The schedule depends on the permit and on what I find when I look at what the room will stand on, so you'll see your own figure in the written estimate after my visit.

How do you know your patio is ready to become a room?

  • A patio nobody uses

    If the chairs out back sit empty most of the year because of the sun, the bugs or the dust, the space usually needs walls and a roof more than new furniture. Each season you wait is another one you spend indoors looking out at it.

  • Screens torn or sagging

    Torn, sagging or patched screens on an older enclosure usually mean the panels have had their run. Left alone, the gaps let bugs and leaves in, and the room slowly turns into storage.

  • Too chilly come evening

    If the patio is pleasant at noon but you head inside once the air cools, an open or screened space can't hold any warmth. That usually means you want glass, and maybe a room you can heat, and it's much better to decide that now than after the room is built.

  • Sunroom additions

    If you want the new room to feel like part of the house rather than a closed-in patio, an addition ties it into your home.

  • Four season sunrooms

    For a room you'll use on cool winter evenings as much as on summer afternoons, a heated and cooled room is the better fit.

How we build your vinyl sunroom

I start by asking how you'll use the room. Then we go over exactly which windows it will have, screens, plain glass or all weather, so the estimate shows clearly which kind of room you're paying for. If there's any chance you'll heat or cool it, we plan the insulated windows and the insulation in the walls, floor and roof now, because they go in far more easily while the room is being built and adding them later can often cost more. From there we check what the room will stand on, put up the frame and roof, set the windows and doors, seal everything against the weather and leave your yard clean.

Some homeowners want the room to look like part of the house, with the roofline and walls carried through, and that's the work we do as sunroom additions. If you already know you'll want it comfortable all year, we'll point you toward four season sunrooms, which are planned for heating and cooling from the start.

  • Screened room

    This suits you if you mainly want shade and fewer bugs and will use the room in mild weather. It's the simplest version, and with no glass it won't hold any warmth.

  • Three-season room with plain glass

    This suits you if you want shelter from wind, dust and the evening chill but don't plan to heat or cool the room. These rooms generally have uninsulated windows, so they're comfortable most of the year rather than all of it.

  • Four-season room with all-weather windows

    This suits you if you'll heat and cool the room and use it like any other room in the house. It takes more planning and paperwork up front, and it's the one I'd recommend if you want it comfortable every month of the year.

Why Fountain Valley homeowners call Fountain Valley Sunrooms & Patios for vinyl rooms

  • I look underneath before building

    I come out to measure and look over every job myself, because I grew up on a farm where you checked the barn floor before you drove a tractor onto it. A sunroom is only as sound as what it sits on, so that's the first thing I look at.

  • Rooms sized for Fountain Valley lots

    The city limits how much of a single-family lot can be covered by buildings and requires open space in the back yard, so I measure the yard as well as the patio before I suggest a size. It's also why we won't talk you into more room than you need.

  • Licensed and insured before we start

    We're fully licensed and insured. A sunroom attaches to your house, and you should have that protection in place before anyone sets a ladder against it.

  • Our own business since 2023

    I started this business in Fountain Valley in 2023 after years of sunroom and patio work. That's three years under our own name, and we've kept it by giving honest advice about which room you actually need.

What matters most is a room that's sound underneath and the right size for how you'll use it. Please send us a message and I'll come out and take a look.

What happens after you call about a vinyl sunroom in Fountain Valley?

  1. Call or send a message

    Call (657) 329-2023 or use the form, and we'll set up a time for me to come to your house. We take calls Monday through Friday from 8 AM to 10 PM and on weekends from 6 AM to 9 PM.

  2. I measure and write it up

    I measure, look at what the room will stand on and ask how you plan to use it, then send you a written estimate in plain words. It spells out what's included, down to which windows you're getting, so you can compare it fairly with any other quote.

  3. We handle permits and paperwork

    If you go ahead, we prepare the plans, file them with the city and meet the inspector. We'll tell you early what we need from you, such as approval from your HOA.

  4. Build, finish and walk through

    I'm on site with our crew until the room is finished. Then we walk through it together so you can try every window and door before we call it done.

Common questions

  • How much does a vinyl sunroom cost in Fountain Valley?

    A sunroom in Orange County usually costs about $120 to $170 per square foot. That's the going rate across the county, not a price of ours. Larger rooms and rooms with heating and air conditioning tend to land toward the higher end, and you'll see your own figure in the written estimate after I've measured.

  • What is the best way to choose between a three-season and four-season sunroom?

    Decide first whether you'll heat or cool the room. A four-season room generally has heating, cooling and all-weather windows, and a three-season room generally has neither. Under California energy guidance, heating or cooling a space that wasn't heated or cooled before counts as an addition, so a certificate of compliance goes in with the building permit application, and we include it in the permit paperwork we prepare. If you're unsure, tell me how you picture using the room in January and we'll work it out from there.

  • Do I need a building permit for a sunroom in Fountain Valley?

    Plan on it. In Fountain Valley, anyone who intends to build, enlarge or alter a building or structure first applies to the city's building official for permits, and adding a sunroom enlarges your house. When your room needs a permit, we take care of the filing for you.

  • How big can I make a sunroom on my Fountain Valley lot?

    On a single-family lot, Fountain Valley limits the share of the lot covered by buildings to 60%, counting sheds and other accessory structures, or 50% on lots of 10,000 square feet or more. The city also requires 1,000 square feet of open space in the rear yard, so a backyard sunroom has to be sized to leave that space open. The city has adopted the California building codes and may have amended them, so for anything specific to your lot, the city's Building Department can answer your questions.

  • Who can legally build a sunroom in California?

    In California, anyone who contracts for work of $1000 or more in labor and materials combined needs a current, valid license from the Contractors State License Board. That includes a sunroom maker that builds the room at your house, so please ask anyone who quotes you whether they hold one.

  • How do I take care of a vinyl sunroom?

    Keep the door and window tracks clean and, as one maker's care guide advises, use a pure silicone spray on them rather than an oil-based lubricant so they keep sliding smoothly. The same guide says to keep the weep holes, the small drain openings in the frame, clear so water can drain out. I'll point them out when we walk through the finished room.
