Patio-to-sunroom conversion in South Gate CA - a room you'll actually use in summer
Tired of a patio slab that only holds folding chairs? We enclose it into a room with walls, a roof and windows that open.
Can I turn my concrete patio into a sunroom?
A patio-to-sunroom conversion in South Gate takes the concrete patio you already have and closes it in with walls, a roof and windows, so you get a room you can sit in instead of a slab you walk past.
Most people who call me have a patio they're tired of looking at, a slab that bakes in the afternoon and gets used twice a year. The price moves with the size of the room, whether you want it insulated with heating and cooling or kept as lighter glass walls, how many windows open, and how much work it takes to tie the walls and roof into your house. The schedule mostly turns on the city's permit steps, which run longer on bigger projects, and the written estimate I give you after seeing your patio spells out what's in the price and what isn't. If all you want is shade and fewer bugs, a screen room is a smaller job and may suit you better.
How we handle a patio-to-sunroom conversion
I start where your slab ends. Where the patio meets the house, and whether it runs past the foundation, shapes the walls and how water gets handled, because walls on a slab that reaches past the house have to be anchored, kept dry at the base and given a clean step between the old floor and the new one. Once that's settled, our crew frames the walls, ties the roof into the house, sets the glass and doors, and builds in insulation if you're going with a fully indoor room. We plan for windows that open from the start, since a closed glass room in summer is an oven with a nice view. Then we trim it out and clean up.
If what's out back is a wood deck rather than concrete, the job is a deck-to-sunroom conversion, and it starts with whether the deck can carry walls and a roof. If you already know you want the room heated and cooled like the rest of the house, our all season rooms are the same idea built for every month of the year.
What a patio-to-sunroom conversion goes through in South Gate
The City of South Gate says building permits are typically required for any home improvement, alteration or construction project, and its list calls out pools and spas but doesn't mention sunrooms, so ask Building & Safety how your conversion is classified instead of guessing either way. A project valued over $50,000 or adding more than 800 square feet of new construction needs Public Works review and approval, and once Planning and Public Works sign off, the plans go to Building & Safety. If the work disturbs a bearing wall or the roof structure, which can happen when a new roof ties into the house, the city also requires approval from the regional air quality agency. We take care of those permit steps and tell you early if plans or reviews have to come first. If you'd rather build it yourself, the city asks owner-builders for ID showing they live on the property, which can't have more than two units, plus workers' comp for any helpers from outside the household.
Back patios around here take hard afternoon sun for much of the year, so we look at which way yours faces before deciding how much glass goes on that side and where the opening windows belong. We see the same thing on jobs in Lynwood and Huntington Park, and a west-facing patio gets more thought about shade and airflow than one tucked behind the garage.
How a patio conversion works
Call or send the form
You call (213) 376-0861 or fill out the form, and we set up a time for me to come see the patio. Evenings and weekends are fine to call.
I come look at it
I come out, look at what the room will sit on and where it meets the house, and ask how you plan to use it. A room for morning coffee and a room for a home office are two different rooms.
You get a written estimate
The estimate is in writing and says what's in it and what isn't, so you're not finding out about extras halfway through. If a cheaper room fits how you'll really use it, I'll tell you, because I'd rather sell you that than the wrong one.
We permit, build and walk through
We take care of the permit steps with the city, then build the room. When it's done, I walk it with you before we call it finished.
Get a written estimate for your patio conversion
We reply within one business day to set up a time. I come out, look at your patio and the wall it'll tie into, and you get a free in-person estimate with no obligation to go ahead.
Questions before you enclose your patio
Should I pick a three-season or a four-season sunroom?
Pick a four-season room if you want it to work like part of the house, and a three-season room if you mostly want a covered spot that still feels close to the yard. A four-season sunroom is insulated, heated and cooled like any indoor room, while a three-season room uses glass panels without insulation. Most of my advice comes down to one question, which is when you'd actually sit in it.
What causes a sunroom to get too hot in summer?
Trapped heat, mostly. One sunroom maker notes that an enclosed room stores heat in summer and can get quite uncomfortable without enough panels that open or enough airflow. Planning those openings early is what keeps the room usable in July and not just in March.
How much does a patio-to-sunroom conversion cost in South Gate?
The cost comes from the room you choose and what your patio needs before walls can go on it, so your figure comes from the written estimate after I've seen it. A four-season room with insulation, heating and cooling runs more than a three-season room, and a slab that reaches past the house or a roof that's awkward to tie into adds work. Picking the room you'll use, not the biggest one, is usually the best way to keep it in hand.
Does a sunroom contractor need a license in California?
Yes, for nearly any sunroom job. The California Contractors State License Board licenses anyone who builds or alters a structure when the project needs a building permit or totals $1,000 or more, and a patio conversion is almost always well past that figure.
What energy rules does a sunroom have to meet in California?
The state Energy Code has energy, water efficiency and indoor air quality requirements for additions and alterations to existing houses, and a patio conversion is the kind of project it covers. The efficiency standards for the walls, roof, windows and doors depend on the climate zone the house sits in, which matters most when you're choosing a fully insulated room.
How do I take care of a sunroom after it's built?
Give it a good look once a year. One maker's guide suggests an annual inspection of the sunroom roof and gutters, which is where leaves and standing water cause trouble first.
Why South Gate homeowners call South Gate Sunrooms & Patios for patio conversions
Our own crew, checked as built
Our own crew does the building, and I check on the work as the room goes up. The person who looked at your slab is the one watching how the walls meet it.
Building sunrooms since 2017
We've built sunrooms and patio rooms since 2017, nine years now. That's long enough to know which rooms people sit in and which end up storing the lawn chairs.
Licensed and fully insured, every job
We're licensed and fully insured. That counts on a conversion, because the work ties into your house's walls and roof.
We find the right permit office
We're based in South Gate and work in the cities and county areas around it, and some have their own building office while others are county areas. We find out which office handles your address before we draw anything, so you're not waiting on the wrong desk.
If you've got a patio you're tired of looking at, send us a note or call (213) 376-0861 and I'll come take a look.
Other rooms we build
Deck-to-sunroom conversion
For a wood deck worth keeping, where the first job is checking the posts and beams before anything gets built on them.
All season rooms
A good fit if the room has to work as an office or guest space in January as well as it does in July.
Call or send photos of your patio
Call (213) 376-0861 or use the form with a few photos, the rough size and whether you want heating and cooling, so I show up already knowing which room we're talking about.
