Sunroom contractor services in Fountain Valley, CA
Fountain Valley Sunrooms & Patios is a sunroom contractor in Fountain Valley, CA, with 16 services, from closing in a patio to building a solarium or putting a room on your deck. The price mostly depends on the size of the room, the walls and glass you pick, and whether the slab, deck or cover underneath needs work before we build on it. The schedule depends on the permit review, any HOA approval and that same base. Your free on-site estimate gives you the figure for your own house in writing, with everything that's included spelled out.
Sunroom additions
A sunroom addition is a new room built onto your house, with its own floor, glass walls and a roof tied into the one you have. It suits families who want more living space without a full addition.
Four season sunrooms
What makes a room four season? Insulated walls, insulated glass and a roof built like the rest of the house, so the room can be heated and cooled like any other.
Three season sunrooms
We build three season rooms with lighter framing and simpler glass or screens. They're for homeowners who want a bright room without paying for full insulation.
Patio enclosures
If your covered patio mostly collects dust and leaves, an enclosure closes it in with windows or screens. Then you can use the space you already have.
Custom sunrooms
A custom sunroom is drawn for your house and yard, matched to its roofline and windows and to how you'll use the room. It isn't picked from a standard kit size.
Sunroom construction
We handle the whole build, from footings and slab work through framing, glass, roof and trim. It's for homeowners who want one crew answering for all of it.
Sunroom remodeling
Is your sunroom drafty, leaky or just never used? We replace tired glass, roofing, flooring and trim so it becomes a room you'll actually sit in.
Screen room installation
A screen room gives you a roof and screened walls, so you get fresh air and shade without the bugs. It's a good fit when you don't need glass.
Patio-to-sunroom conversion
Already have a slab and a cover out back? We check whether the slab and posts can carry a real room, then build walls, glass and roof on what's sound.
Deck-to-sunroom conversion
A deck can become a sunroom when its footings and framing are strong enough to carry walls and a roof, so we look underneath before anything else.
All season rooms
We build all season rooms with insulated walls and glass. They're for homeowners who want a sunroom that works as a den, office or dining room any month of the year.
Enclosed patio rooms
When an open patio isn't getting used, we enclose it with knee walls and windows. You get a patio room that still feels like part of the yard.
Solarium installation
A solarium has glass overhead as well as on the walls, so light fills the whole room. It's for the homeowner who wants as much sky as they can get.
Patio cover installation
We build solid and lattice patio covers for shade over a slab or deck. Each one is sized to your yard and tied neatly to the house.
Sunroom design
Not sure what kind of room you need? Design starts with how you'll use the space and what your lot allows, then settles size, glass and roofline before anything is built.
Vinyl sunrooms
Vinyl framing doesn't need painting and is easy to keep clean. A vinyl sunroom suits homeowners who want a bright room with little upkeep.

Fountain Valley homes and backyards
Fountain Valley is a city of neighborhoods and backyards, and a lot of its open space sits in a couple of well-used places. Mile Square Regional Park is a large county park inside the city, with golf, two lakes for fishing, archery, bike riding, paddle boats and picnic spots. The city's Recreation Center & Sports Park has soccer fields, tennis and racquetball courts, lighted basketball courts, and softball and youth baseball fields.
Most of the houses we visit here have a slab, a deck or an older cover out back that the family has mostly stopped using. That space is what we turn into a room. I started this business in Fountain Valley in 2023, and you can read how I came to this work if you'd like to know who you'd be hiring.

About usFrom your first call to a finished room
Call or send a message
You call (657) 329-2023 or send the form with a few lines about your house and the room you're picturing. We reply within one business day to set a time for me to come out. The visit is free, and you're under no obligation to go ahead.
I measure and write it up
I come to your house, measure the yard and look closely at what the room will stand on, whether that's a slab, a deck or an existing cover. I'll ask how you plan to use the room. Then I send a written estimate in plain words that spells out what's included.
We file and we build
If you decide to 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 HOA approval. Once that's done, I'm on site with our crew through the build, so you know who to ask.
We walk through it together
When the room is finished, I walk through it with you and we look over the doors, windows, trim and roofline together. Our crew cleans up as we go and again before we leave. Please ask anything you're still wondering about while we're standing in the room.

Common questions
How much does a sunroom cost in Fountain Valley?
It depends on the room's size, the walls and glass you choose, and whether the slab or deck underneath needs work first. A four season room with insulated glass costs more than a screen room or three season room of the same size. Your free on-site estimate gives you the figure for your house in writing.
How much of a down payment can a contractor ask for on a sunroom in California?
Under the Contractors State License Board's rules, a contractor can't ask for or accept a down payment of more than $1,000 or 10 percent of the total contract price, whichever is less. The board says this applies to all home improvement projects, so it covers a sunroom.
How long does it take to build a sunroom in Fountain Valley?
The timeline depends mostly on the permit review, any HOA approval and how much work the base needs before we build. A sound slab or deck moves things along, and one that needs repair adds time. I'll walk you through what your project depends on at the estimate.
Is Fountain Valley Sunrooms & Patios licensed and insured?
Yes, we're fully licensed and insured. In Fountain Valley, every subcontractor also needs a city business license before starting work, so it's fair to ask any contractor you're considering about both.
Can you turn my existing patio or deck into a sunroom?
Often yes, as long as the slab or the deck's footings and framing can carry walls and a roof. That's the first thing I check at the estimate. If the base needs work, I'll tell you plainly before we plan anything above it.
Do you guarantee your sunroom work?
Yes, our promise is satisfaction guaranteed. I'm on site through the build, and we walk the finished room together, so anything you're unhappy with comes up while we're still there.
What's the difference between a three season and a four season sunroom?
A four season room has insulated walls, insulated glass and a roof built for heating and cooling. A three season room uses lighter framing and simpler glass or screens. I'll ask how you'll use the room before recommending one, because there's no sense paying for insulation you won't use.
Do I need a permit to build a sunroom in Fountain Valley?
Please check with the city before you build. Its Building & Safety Division issues permits to build, enlarge or alter a structure, and its list of exempt work covers finish work like painting and tiling, not new rooms. You can call the Building Division at 714-593-4429, and when your project needs a permit, we prepare and file the plans.
