Is a four season sunroom right for your Long Beach house?
A four season sunroom in Long Beach is a glass room built as part of your house, with insulation, wiring and its own heating and cooling, so it stays comfortable and connects to the rest of your home all year.
Most people who call us have a patio, a deck or a back wall they want more use out of, and they want it to feel like a real room instead of a porch with windows. Size, materials and the foundation set most of the price, and the schedule mostly turns on the permit, any foundation work and how quickly the big choices get settled. I measure, look at your base and the wall the room will join, and walk you through the choices so the written estimate you get is your own figure, not a guess.
How we build a four season sunroom
A four season room should feel like part of the house, so the first thing we settle with you is whether it opens into the house or stays behind your existing doors, because that choice shapes the glass, the base and the heating plan. From there our crew sets the base the room sits on, frames it, sets the glass and insulation, runs the electrical and ties in the heating and cooling. Then we finish the inside to match the rest of your house and clean up so the yard goes back to being your yard.
Not everyone needs a fully heated and cooled room. If you'll mostly use the space on mild days, a three season sunroom can be the better fit, and if you just want an existing patio closed in, our patio enclosures cover that.
Open to the house
This suits you if you want the room to read as part of your living space, with the back door or part of the wall opened up into it. One industry sunroom specification counts a heated or cooled room that's open to the main house as habitable space, so this is the choice when you want a true extra room.
Behind your existing doors
This suits you if you'd rather keep your back door as the line between the house and the sunroom, with the room on its own heating or cooling control. The same specification counts that closed-off room as non-habitable space, so it's worth knowing which one you're after before design starts.
Building a four season sunroom in Long Beach
In Long Beach, building or changing a structure takes a building permit and inspections through the city's Building and Safety Bureau, and a four season room joined to your house is that kind of work, so we plan on a permit from the start. When a job needs one, we pull it and handle the paperwork with the city. Zoning is the other early question, and the city's Planning Bureau asks people to reach out early because it can explain the limits on what you can build on your property.
We're based in Long Beach and work across the cities around it, and on jobs here and in Lakewood and Signal Hill we see a lot of single-story houses with a concrete patio or an older wood deck out back. I check whether that base is level and sound and how the back wall is built, because the room has to tie into both.
Why Long Beach homeowners call Long Beach Sunrooms & Patios for four season rooms
I come out to every estimate
I come out to every estimate myself, so the person answering your questions on site is the one who plans your room. You get straight answers at the first visit instead of a callback from someone who hasn't seen your house.
We build the room you approved
I sold sunrooms before I moved to building them, and I saw what happens when a room gets sold one way and built another. We've been building since 2021, and I keep every plan simple enough that the crew builds exactly the room we talked about.
Historic and coastal questions asked first
The city says extra requirements may apply in historic districts and coastal zones, so I ask about both at the first visit. That way any extra steps are known before we design anything.
Fully licensed and insured
We're fully licensed and insured. A four season room ties into your back wall, your roof line and your electrical, and that's work you want done by a covered crew.

Frequently asked questions
How much does a four season sunroom cost in Long Beach?
Across the US, adding a four season sunroom usually costs about $20,000 to $80,000 per job, according to a national cost guide. That's the market's range, not our price, and where your room lands comes down to the room itself and the base we find at your house. The written estimate after my visit gives you the figure for your home.
What's the difference between a four season and a three season sunroom?
A three season sunroom is glassed in too, but it has no insulation and no heating or cooling, while a four season room has both. That makes the four season room the one to choose if you want a temperature-controlled room that connects to the house. If you'll mostly use the space on mild days, the three season room is worth a look.
Can a four season sunroom be built on my existing deck or patio?
It can with a prefab sunroom kit, since kits can attach to an existing wooden deck or patio as long as the surface is level. A site-built room needs a proper building foundation, which adds foundation work to the plan. I check your deck or patio at the estimate and tell you which way makes sense.
Who can pull a building permit for a sunroom in Long Beach?
Long Beach issues building permits to contractors who hold a valid California State Contractor's License and an active Long Beach Business License. The homeowner of a one- or two-family house can also pull a permit for the house and related accessory structures under a city information bulletin. On our jobs, that part is ours.
How do I check that a sunroom contractor is licensed in California?
Use the state's online license look-up, which shows a licensed contractor's information and any complaints that have been disclosed. In Long Beach, a contractor with employees also shows proof of workers' compensation insurance when the city issues the permit, so it's fair to ask about that too.
What is the best way to choose glass for a four season sunroom?
Compare the solar heat gain coefficient, the rating for how much of the sun's heat a pane lets in, across the glass options you're offered. One research study found that glass with a higher rating made extreme warmth feel stronger and called the rating critical for comfort. It's a good question to raise for any room that faces hard afternoon sun.
