How do you know it's time for a four season room?
A patio nobody uses
You've got a covered patio or slab out back, but it's too hot by afternoon and too cool once the sun drops, so the chairs just sit there. That usually means the space needs walls, insulation and its own heating and cooling, and every season you wait is another season of space you own and can't use.
A glass room that bakes
If you already have an older enclosure that turns into an oven by noon and gets shut up by evening, it's usually missing insulation and real heating and cooling. A fan or space heater only goes so far, and the longer the room sits unused, the more it turns into storage.
A crowded living room
When the home office, the kids' homework and the TV are all fighting over the same room, you usually need another room more than a nicer patio. A four season room that opens to the house can give you that space, and putting it off usually means another year of everyone squeezed together.
What is a four season sunroom, and does it fit my house?
A four season sunroom is a glass-walled room built onto your house with insulation, wiring and its own heating and cooling, so it stays comfortable in August and in January. We design and build four season sunrooms in Lynwood, CA and the cities around it, usually for homeowners turning a patio, deck or slab into a room they'll actually use.
Most people who call us have a space out back they can only use part of the day, and the first job is working out which kind of room really fits how you live before anything gets built, which is why I'll talk through a lighter three season sunroom with you too. The price mostly moves with the size of the room, the materials and the foundation it needs, and the schedule mostly turns on the drawings and the city's plan review, which we prepare and handle for you when the job needs a permit. Your estimate spells out what's in it, so you can see where the money goes before you sign anything.

How we build a four season sunroom
I've been helping people pick the right room since 2013, and it starts with me measuring the space and asking how you'll use it, because a reading nook and a playroom need different things. Then I walk you through the two choices that shape comfort most. As a general rule, a solid, insulated roof holds heat in during winter and keeps the summer sun from overheating the room, while a glass roof gives you that open-sky look at the cost of hotter afternoons. Straight, vertical glass walls cost less than sloped glass, insulate more easily and are less prone to leaks, fogging and breakage. My own lean is a solid roof and straight glass walls, since you give up a little of the look for comfort and fewer headaches, but I want you choosing with both sides in front of you. From there our crew sets the foundation, frames and roofs the room, insulates it, brings in power and heating and cooling, sets the glass and finishes the inside.
Not every space needs a full four season room. If you mostly want a bright room for mild months without heating and cooling, a three season sunroom is usually a simpler build, and if you mainly want to close in the slab you already have against wind, dust and bugs, our patio enclosures may be all you need.
Other ways to close in your space
Three season sunrooms
For a glass room you'll enjoy most of the year without paying to insulate it and run heating and cooling to it.
Patio enclosures
For sheltering the patio you already have so it's usable more often, without taking on a full addition.
What happens when you call about a four season sunroom in Lynwood?
Call or send the form
Reach us at (424) 296-8574 or through the form below, and we'll set a time for me to come out to your house. It helps to tell us whether there's a patio, deck or bare ground there now.
I visit, measure and estimate
I come out to see the space, take measurements and listen to how you want to use the room, and we go over the roof, the glass and whether it opens to the house. Then we write up an estimate that spells out what's in it, so you can see where the money goes before you sign anything.
Permits, build and walk-through
If the job needs a permit, we prepare the drawings, handle the application with the city or county office for your address and line up the inspections, then our own crew builds the room under a lead installer while I check in at each stage. When it's done, we walk through the room together and I show you how to look after it.
Questions before you book a four season sunroom
What is the difference between a four season and a three season sunroom?
A four season sunroom is insulated and has electricity and its own heating and cooling, while a three season sunroom is enclosed with glass but has no insulation or heating and cooling. That's what lets a four season room stay comfortable on a hot afternoon or a cold night. I'm happy to walk you through both on the visit.
How much does a four season sunroom cost near Lynwood, CA?
A 200 square foot four season sunroom in Los Angeles County usually costs about $28,000 to $60,000 for the whole job. That's the going range across the county, not our price, and where your room lands depends mostly on its size, the materials you pick and the foundation it needs. Our estimate spells out each of those for your space.
Who issues building permits for a sunroom in Lynwood, and what comes first?
The city's Building and Safety Division issues building permits and reviews plans for building or altering any structure in Lynwood, which covers building onto your house. Before plans go to building review, the city wants a completed plan check form with Planning Division approval attached, and energy calculations have to be part of the plans. A separate grading permit is needed if 25 yards or more of soil is disturbed, and any work out in the city's right of way along the street needs its own encroachment permit and Public Works approval, so we sort out all of that with the drawings when your job needs a permit.
Should a four season sunroom open to the house or be closed off?
Open it to the house if you want it to feel like another room of your home, and keep it closed off if you'd rather it run on its own heating and cooling. A national sunroom standard labels a heated or cooled room that opens to the house a habitable, conditioned sunroom, and one sealed off from the house's heat with its own temperature control non-habitable. How the city treats your particular room gets settled in plan review.
What is the best way to add a four season sunroom to an existing patio or deck?
A site-built room needs a proper building foundation, while prefab sunroom kits can attach to an existing wooden deck or patio as long as the surface is level. So a level patio or deck may make a kit worth a look, and a room built on site means planning for foundation work. I'll look at what you've got on the visit and tell you which way I'd go.
How do I check if a sunroom contractor is licensed in California?
You can check a contractor's license status through the Contractors State License Board, the state board that regulates the construction industry and explains how to look a license up. The board also has guidance on writing a clear contract and avoiding disputes and mechanics liens on your home, which is worth a read before you sign with anyone. We're licensed and insured, and I'm glad to go over our paperwork with you.
