What's involved in remodeling a sunroom in Fountain Valley?
Sunroom remodeling in Fountain Valley means upgrading the sunroom you already have, usually with better insulated windows and added insulation in the walls, floor and roof, so the room is comfortable more of the year and uses less energy. At Fountain Valley Sunrooms & Patios, we do this work in Fountain Valley and in many cities around it across Orange County.
Many calls start with a room that bakes by early afternoon in summer, feels chilly on winter evenings and has slowly turned into storage. What moves the price most is whether you want the room heated and cooled, along with its size and whether what it sits on needs work first. The schedule turns mostly on the windows you choose and on the city's permit review when the work alters or enlarges the room, and in that case we prepare the plans, file them with the city and meet the inspector. If you're leaning toward a four season room, the visit is where we sort that out, and my written estimate spells out what's included.
How do you know your sunroom is ready for a remodel?
Too hot to sit in
If the room is too warm to use by early afternoon, the glass is usually single pane or the roof panels have little or no insulation. Left as is, the heat keeps you out of the room, and if it opens to the house it pushes into the rooms next to it as well.
Fogged or wet windows
Haze between the panes or water on the sill usually means a failed seal or drainage that has stopped working. Water that sits in a frame works into the trim and the floor, and that repair grows the longer it waits.
A room used for storage
When the sunroom door stays shut and boxes move in, the room is usually too hot, too cold or too drafty to enjoy. You're keeping up space you don't use, and the right upgrades are how you get it back.
Often paired with a sunroom remodel
Screen room installation
If you'd rather have open air without the bugs than glass and air conditioning, a screen room may suit your yard better than a full remodel.
Patio-to-sunroom conversion
When the space you have is really a covered patio rather than a proper room, building it up from the slab is the honest place to start.
How we approach sunroom remodeling
I start by looking over the room you have, from the slab or footing it sits on to the roof panels and every window and door, because new glass on a weak base is money wasted. Then I ask how you plan to use the room. We price the windows, insulation and other upgrades as one plan, so you can see the whole job and choose what to do first, which matters because insulated windows and insulation go in most easily when a room is first built and adding them piece by piece later can often cost more. Once you've chosen, our crew takes out the old glass and panels, insulates the walls, floor and roof where the plan calls for it, sets the new windows and doors, trims it out and cleans up before we leave.
Some rooms are better served by a different job. If you want fresh air more than climate control, screen room installation may be the plainer answer, and if your sunroom is really a covered patio with panels added over the years, a patio-to-sunroom conversion builds it properly from the ground up.
Upgrade it as a three season room
This suits you if you use the room spring through fall and don't plan to heat or cool it. We replace tired panels and screens and fix what's underneath, which keeps the cost down and the room pleasant on mild days.
Convert it to a four season room
This suits you if you want the room heated, cooled and open to the house as part of daily life, and the industry's sunroom standard then treats it as a living space, so its windows have to hold back air leaks and water and keep heat in check. The state Energy Code also applies to alterations like this, not only to new building, so we plan the windows and insulation to meet it.

The owner checks underneath first
I come out to measure and look over every job myself, starting with the slab, deck or footing the room stands on, and I work on site beside our crew through the build. Growing up on a farm taught me to look under anything before trusting it, and a sunroom is no different.
Fully licensed and insured work
We're fully licensed and insured, and you're welcome to ask about it before any work starts. Our promise is a short one, satisfaction guaranteed.
Lot rules checked before enlarging
Fountain Valley limits how much of a single-family lot can be covered, and patio covers and other accessory structures count toward it, so I check your lot before we plan to make a sunroom any bigger. I started this business here in 2023 after years on sunroom and patio jobs, and those city rules are part of every plan we draw.
A remodel is only as sound as what it stands on, so please arrange a visit and let me look underneath before you pick a single window.
What happens when you call about a sunroom remodel in Fountain Valley?
Call or send a message
Call (657) 329-2023 or use the form, and we'll get back to you to set up a visit at a time that suits you. It helps to think ahead about how you'd like to use the room.
I measure and look underneath
I come out, measure, check what the room stands on and ask how you plan to use it, then send a written estimate in plain words. It spells out what's included and what each upgrade adds, so you can see the whole cost and decide what to do first.
We permit, build and walk through
If you go ahead, we take care of the permit and city paperwork and tell you early what we need from you, such as any HOA approval. I'm on site with our crew until the room is finished, and then we walk through it together.
Common questions
How much does sunroom remodeling cost in Orange County?
A sunroom in Orange County usually costs about $120 to $200 per square foot, and that's the going rate across the area, not our price. Larger rooms that need a foundation and heating and air conditioning sit toward the top of that range, while a remodel of the room you have depends mostly on which upgrades you choose. The written estimate from our visit gives you the figure for your room.
Do I need a permit to remodel my sunroom in Fountain Valley?
Expect one if the work alters, enlarges or repairs the room, because Fountain Valley's building official issues permits for that work and the city's exempt list names finish work like painting and tiling. If you're unsure about your project, the city's Building Division can tell you, and when a permit is needed, the filing is ours to handle.
What's the difference between a three season and a four season sunroom?
A four season sunroom is heated and cooled and has all-weather windows, while a three season room has no heating or cooling and uses uninsulated windows or screens. That's why the first choice in any remodel is whether you'll heat and cool the room, since the answer decides the windows it needs.
How much can a contractor ask for as a down payment on a sunroom remodel in California?
In California, a down payment on a home improvement job can't be more than $1,000 or 10 percent of the contract price, whichever is less, and there's no exception for special-order materials. Any home improvement job over $500 also needs a written contract that tells you of your right to cancel, and any changes go in writing too. Please read both before you sign with anyone.
How do I keep my sunroom from getting too hot in summer?
Shade the glass from outside with overhangs, awnings, shutters or trellises, which is the general guidance for cutting unwanted summer heat. Overhangs do less on east and west windows because the sun sits low at sunrise and sunset, so I look at which way your room faces before suggesting one.
How do I take care of sunroom windows and doors after a remodel?
Keep the door and window tracks clean, use pure silicone spray instead of an oil-based lubricant and keep the weep holes clear so water can drain, which is what one sunroom maker's guide advises. A clogged weep hole is a common reason water ends up on a sill, so it's worth a look each season.
