Sunroom Contractor in Lynwood, CA - Rooms Built on Your Existing Patio
South Gate Sunrooms & Patios is a sunroom contractor building sunrooms, patio enclosures and screen rooms for Lynwood homeowners on the slab, deck or tired patio cover already out back, so it becomes a room you actually use.

Lynwood houses and the backyards behind them
Lynwood sits right next to South Gate, where we're based, so it's a short drive for our crew. Most of our calls here come from single-family houses on modest lots, the kind with a concrete patio out back, a detached garage and a side yard just wide enough for a wheelbarrow, with apartments and shops along the busier streets. The houses look a lot like what we see in Willowbrook, and the calls sound the same too. Somebody has a patio they're tired of looking at.
A lot of these houses have been added onto over the years, a patio cover here and a back room there. That's usually where our job starts, because a slab poured for a barbecue or a cover built for shade wasn't meant to hold walls, and we need to know what's under it before anything gets drawn.
Working in Lynwood: permits, licenses and what sets the price
In Lynwood, building permits come from the city's own Building and Safety Division, not the county. The division reviews plans for building or altering any structure in the city and sends inspectors to check the work against the codes, so a sunroom waits on that review before we pour or frame anything. Before you hire anyone for work that needs a building permit, know that California requires that contractor to hold a current license from the state contractor board, so ask to see it. We're licensed and fully insured, we take care of the permit steps with the city, and I tell you early if drawings or a review have to come first.
The price mostly turns on what the room sits on and how closed in you want it, and the schedule mostly turns on the city's review. We build the same way in Huntington Park and the other cities around Lynwood, but every building office runs its own review, so I don't promise a start date until the permit is in hand. Your written estimate spells out what's in the price and what isn't.

Patio-to-sunroom conversion
Most Lynwood calls start with a concrete patio that gets used twice a year. We check whether that slab can carry walls and a roof, then build the room on it or add the footing it needs.
Four season sunrooms
On a smaller Lynwood house, the sunroom often turns into the extra room the family was missing, so it has to be comfortable every month of the year. Our four season sunrooms get an insulated roof and real windows so you use the room like the rest of the house.
Patio enclosures
Plenty of houses here already have an aluminum patio cover that's sound but open on three sides. When the posts and roof hold up, we can close it in for less than a new room, and when they don't, I'll tell you.
Screen room installation
If you mostly want the bugs out and the breeze in, a screen room costs less than a glass one and does the job. I'd rather build you that than a room you end up paying to cool.
Sunroom remodeling
Some Lynwood houses have an older add-on room that leaks where it meets the house or bakes by noon, which makes it an expensive porch. We redo the tie-in to the house and replace the roof or glass so people sit in it again.
Patio cover installation
If a full room is more than you need right now, a solid patio cover shades the slab and keeps rain off the furniture. We can set it up so walls can be added later if you change your mind.
What Lynwood lots ask of a sunroom
The slab behind most Lynwood houses was poured for a patio, not a room. It's often thin at the edges, cracked from years of settling, or sloped toward the yard so rain runs off, and that's fine for lawn chairs but not for walls and a roof. We check the thickness and the edges before we price anything, and where the slab won't carry the room we add a footing, a deeper strip of concrete along the edge for the walls to sit on, instead of hoping.
The other half of the job is the house wall. On older stucco houses, the roof edge where the room ties in has usually been patched a few times, and that joint is where an add-on room leaks if it's rushed. We open it up enough to see what's there and flash it, sealing the joint with metal so water runs off instead of in.

How a Lynwood sunroom gets built
Call and tell us what's there
You call (213) 376-0861 or send the form, and we set a time for me to come out. It helps if you're home, because I'll want to hear how you plan to use the room.
I look at the base
I check the slab, deck or wall the room ties into and talk through what kind of room fits. You get a written estimate that spells out what's included and what isn't, so you know what you're paying for.
We handle permits, then build
We take care of the permit steps with the city, and building waits on its plan review, so I tell you early if drawings or changes come first. Our own crew builds the room, and I check on the work as it goes up.
We walk the finished room
Before we call it done, I walk the room with you and we look at the windows, doors and the joint at the house together. Satisfaction guaranteed.
Lynwood sunroom questions answered
Do I need a permit to enclose my patio in Lynwood?
Plan on one, because the city's building office reviews plans for the construction and alteration of any building or structure, and closing in a patio is both. The city's posted permit types name things like re-roofs, electrical and solar rather than sunrooms, so we confirm what your project needs before drawings start and handle the permit steps from there.
Does my sunroom contractor in Lynwood need a state license?
Yes. California requires a current license from the state contractor board for anyone who contracts for work on a project that needs a building permit, uses employee labor, or contracts for work worth $1,000 or more in combined labor and materials. The board's exception only covers someone who doesn't advertise as licensed, uses no employees, needs no permit and stays under that $1,000 mark, which leaves out a sunroom crew.
When does a grading permit apply in Lynwood?
An undated city submittal sheet says a separate grading permit is required once 25 yards or more of soil is disturbed, which a room built on an existing slab usually won't come near. New footings or a leveled yard can get closer, and the same sheet says work in the city right of way, the strip along the street out front, needs its own encroachment permit. We check both before plans go in.
How do I check earthquake hazard zones for my Lynwood address?
Type your address into EQ Zapp, the state geological survey's map tool, and it shows whether your property sits in any of its mapped earthquake hazard zones. It's worth a look before you plan a room that ties into the house, and if something shows up, tell me at the estimate so we can ask the city what it means for the plans.
How much does a sunroom cost in Lynwood?
The biggest swing in a Lynwood sunroom price is the slab or deck it sits on, followed by the roof and glass you pick. A patio slab that can already carry walls keeps the cost down, while new footings, an insulated roof and wiring for lights and outlets push it up, and a screen room is usually the cheapest way to get a room you'll use. You get a written number after I've seen your yard.
What is the best way to turn an old patio cover in Lynwood into a sunroom?
Start by finding out whether the cover and the slab under it are sound, because walls add weight and catch wind that a shade cover never had to handle. If they pass, we can enclose what's there. If they don't, replacing the cover with a roof built for walls usually costs less than patching it twice.
