Why homeowners call us for their sunroom
Built for how you'll use it
We talk through how you'll really use the room before we build, so you're not paying for heat you won't run or skipping insulation you'll miss.
The person who looks plans it
I look at every job and plan it myself, so the person pricing your room is the one who's seen what it ties into.
We sort out the permit office
Some places we work have their own building office and some are county areas, so we find out which handles your address and deal with them.

Building sunrooms in South Gate
South Gate is home base for us, a city of houses with backyards where a bare slab or an old porch out back is a common sight. Most people here know South Gate Park, the biggest park in the city, where the farmers market sets up every Monday, and Hollydale Regional Park with its dog park off Century Boulevard. You can find both on the city's parks page.
We build all over South Gate and the cities around it, and the call is usually the same one, a patio, deck or porch someone wants to finally use. Work like ours here goes through the city's Building and Safety Division, which checks that new and remodeled construction meets state law and city rules, and we deal with them so you don't have to.

Tell us about the room you have in mind
We reply within one business day to set a time for me to come out and look at your place. The estimate is free and in person, and there's no obligation to go ahead.
About South Gate Sunrooms & Patios

I framed houses when I was young, spent years doing something else, then came back to building through sunrooms because they're small enough to do right and big enough to matter. We're licensed and fully insured, our own crew does the building, and we have pages for 12 of the cities we work in. You can read more about us and how we work.
Sunroom contractor services in South Gate, CA
South Gate Sunrooms & Patios is a sunroom contractor in South Gate, CA, with 16 services, from screen rooms and patio covers to fully insulated rooms you can use all year. The price moves with the room's size, the glass, the insulation, whether it needs heat and whether the slab or deck underneath is ready for it. The schedule mostly turns on permits and any plan review, and your free estimate spells out what's in it and what isn't.

Sunroom additions
We build a sunroom addition onto the back or side of your house, tied into the existing wall and roof like a real room.

Four season sunrooms
A four season sunroom is insulated, glazed and usually heated and cooled, for homeowners who want a room they'll use every month of the year.

Three season sunrooms
If you want a room for most of the year without paying for insulation and heat, a three season sunroom is the lighter build.

Patio enclosures
We close in an existing covered patio with walls, windows and a door, so outdoor space you rarely use becomes a room you'll sit in.

Custom sunrooms
A custom sunroom is designed around your house, its roofline and how you'll use the room, rather than picked from a standard kit size.

Sunroom construction
Our own crew handles sunroom construction from the base to the roof, and I check on the work as the room goes up.

Sunroom remodeling
A sunroom that leaks, runs too hot or never gets used can be remodeled with new glass, roofing or insulation so it earns its space.

Screen room installation
A screen room lets the air through and keeps bugs out, a simple way to get more use from a patio without walls and glass.

Patio-to-sunroom conversion
We turn an open concrete patio into a sunroom, checking the slab first because the room is only as solid as what it sits on.

Deck-to-sunroom conversion
A deck-to-sunroom conversion builds a closed-in room on your deck, after we check that the framing underneath can carry the extra weight.

All season rooms
An all season room is insulated like the rest of the house, for families who need an office, a playroom or space for guests.

Enclosed patio rooms
An enclosed patio room puts a roof, walls and windows over your slab, giving you living space without the cost of a full addition.

Solarium installation
We install solariums with glass roofs as well as glass walls, for homeowners who want the most light and are ready to plan for heat.

Patio cover installation
We install patio covers that put shade and a solid roof over your patio while leaving the sides open to the yard.

Sunroom design
If you can't decide between a screen room and a heated sunroom, sunroom design starts with how you'll use it and ends with a plan.

Vinyl sunrooms
A vinyl sunroom uses vinyl framing that doesn't need painting, a good fit for homeowners who want a room that asks little upkeep.

How a sunroom job goes with us
Call or send the form
Call (213) 376-0861 or use the contact form to tell us a little about your patio, deck or porch, even if all you know is that you're tired of looking at it. We reply within one business day to set up a time for me to come out.
I look and you get an estimate
I come out myself, look at the slab, deck or wall the room will tie into, and ask how you plan to use it. You get a free written estimate that says what's in it and what isn't, so heating, a new slab or permit work don't turn up later.
Permits, then the build
We take care of the permit steps with whichever office handles your address, city or county, so you're not stuck on the phone with them. Once that's cleared, our own crew builds the room, and I check on the work as it goes up.
We walk the room together
I walk the finished room with you before we call it done, so you can open the windows, try the door and point out anything that isn't right. Then it's yours to sit in, which was the whole idea.
Your sunroom questions answered
How much does a sunroom addition cost in South Gate?
I don't give a number until I've seen what the room will tie into, because a sound slab and a slab that needs replacing are two different jobs. The same goes for a deck that may need more framing underneath. Your free in-person estimate puts your number in writing.
Why does a four season sunroom cost more than a three season room?
Insulation, better glass and heating and cooling are what push a four season room's price up. If you'll only use the room part of the year, a three season room is often the smarter buy. I'd rather talk you into the cheaper room than the wrong one.
How long does it take to get a sunroom built in South Gate?
Most of the wait usually comes from permits and plan review, not the build itself. In the city's residential plan check, projects valued over $50,000 or with more than 800 sq ft of new construction also need Public Works review, and we tell you early if plans or a review have to come first.
Does a sunroom contractor need a license in California?
Yes, the state licensing board requires a contractor license for any job that needs a building permit, uses other workers, or totals $1,000 or more in labor and materials. A sunroom clears that bar easily. We're licensed and fully insured.
Who gets the building permit for a sunroom in South Gate?
Either the property owner or a state-licensed contractor with a South Gate business license can, and we take care of the permit steps on our jobs. The city says permits are typically required for home improvement, repair, alteration and construction work, so ask the Building and Safety Division for a ruling on a specific small job.
Is your sunroom work guaranteed?
Yes, our work is satisfaction guaranteed. That's why I spend the first visit on what the room ties into and how you'll use it, because a room that's too hot or leaks is just an expensive porch.
Should I get a solid roof or a glass roof on my sunroom?
For most rooms I'd pick a solid, insulated roof, because a glass roof lets in the most light and also the most heat. A glass roof makes sense if light matters most to you and you're ready to plan for shading or cooling.
Does my contractor need a city business license in South Gate?
Yes, South Gate requires a business license of every business working within city limits, including contractors whose offices are outside the city. It's worth asking any contractor you're considering whether they have one.
