What does adding a sunroom in South Gate involve?

A sunroom addition in South Gate closes in a patio, deck or porch on your house with windows or screens. The finished room can be anything from a screened porch to a room you heat and cool and use like the rest of the house.

Most people who call me are tired of looking at a bare patio or a porch that's seen better days. The price moves with the room type, its size, whether the slab under it is sound and whether you heat and cool it. The schedule mostly turns on the city permit and on whether we have to pour a new slab first. Your written estimate spells out what's in the price and what isn't, so you know your own number before you decide anything.

What a sunroom addition from us includes

I start with one question, whether you want a screened porch, a three season room or a room you heat and cool, because everything after that follows from the answer. Then I look hard at the patio or slab the room will sit on before I quote, since a tired slab can mean starting with a new one. When the job starts, our crew pours or preps the base, frames the walls and roof, ties the roof into the house so water runs off instead of in, and fits the windows, screens and doors. We finish with trim, sealing and cleanup, so you're left with a room and not a job site.

A screened porch is a roof and screens, with no windows and no heating or cooling, and it's the cheapest way to sit outside without the bugs. Three season sunrooms add windows but usually skip heating and cooling, so they cost less and work best when the weather's mild. Four season sunrooms are fully closed in with all weather windows and heating and cooling, which makes them real living space with a bigger price and more rules. I'd rather talk you into the cheaper room than the wrong one.

What South Gate requires for a sunroom addition

South Gate lists additions and patios among the work that needs a permit, so a sunroom addition here goes through the city's Building and Safety Division before we build. The city inspects the work against current California building, electrical, plumbing, mechanical, energy and green building codes, so on a sunroom the wiring and any heating or cooling get checked along with the framing. Plans also have to follow the current Zoning Code, which the city updates from time to time, so we check the version in force for your lot. Some nearby addresses are county areas with a different office, so we find out which office handles yours and take care of the permit steps with them.

We're based in South Gate and work in the cities around it, plus the county areas nearby. Most of what we see is older one-story houses with a concrete patio out back, often under a patio cover that's done its time, and those slabs range from fine to badly heaved. It's the same story on jobs in Lynwood and Downey, so the slab gets a hard look before anything else.

How a sunroom addition works

  1. Call or send the form

    Call (213) 376-0861 or use the form, and we'll set a time for me to come out. It helps to know the room type you're leaning toward and roughly how big.

  2. I check the slab first

    I look at the slab, deck or wall the room will tie into and ask how you plan to use the room. You get a written estimate that says what's in it and what isn't, so you can see exactly what you're paying for.

  3. We clear permits, then build

    If plans or a review have to come first, I tell you early so the schedule doesn't catch you off guard. Once the city signs off, we build the room.

  4. Walk the finished room together

    I walk the finished room with you before we call it done. We open the windows and doors and go over anything you want to ask.

Questions before you book a sunroom addition

How much does a sunroom addition cost near South Gate?

A sunroom in the Los Angeles area usually costs about $16,000 to $120,000 per job, depending on the room. Larger rooms that need a foundation and have heating and air conditioning land at the high end, and a smaller unheated room on a sound slab lands lower. Your written estimate gives you the number for your house.

Do I need a permit to add a sunroom in South Gate?

Yes, the city counts additions and patios as permit work, so a sunroom addition needs one. The details are in the South Gate section above, and that part is on us.

Does a heated sunroom have to meet California energy rules?

Yes. The California Energy Commission says the state Energy Code applies to additions, and a space that gains heating or cooling has to meet the requirements for an addition. That's part of why a four season room costs more than a three season one, and it's worth deciding before the room is designed, not after.

How do I know if my patio slab can hold a sunroom?

The slab usually has to be close to new, without much buckling or cracking. One sunroom maker's guide prefers a new slab or deck, says an existing one needs to be in like new condition and warns that many buckles or cracks make a slab unsuitable and could lead to leaks. If yours doesn't pass, the estimate starts with a new slab.

Is upright glass or sloped glass better for a sunroom?

Upright glass walls are usually the better pick. An older fact sheet says they cost less and are easier to install and insulate than sloped glass, and they're less prone to leaks, fogging and breakage. Sloped glass looks great in a photo, but it's more to keep up with.

How do I take care of a sunroom so it keeps working?

A once-a-year check covers most of it. One sunroom maker suggests looking over the roof and gutters each year, keeping door and window tracks clean with pure silicone spray, and keeping the weep holes, the small openings that let water drain, clear. A clogged weep hole can make a good room look like it leaks.
