Sunroom contractor in Los Angeles - patios and decks turned into rooms
Lightcraft Los Angeles Sunrooms & Patios is a sunroom contractor based in Los Angeles. We turn backyard patios and decks into sunrooms, build sunroom additions and rework older rooms across the city.

Sunrooms on Los Angeles houses, from bungalows to hillside homes
Los Angeles is home for us, and it's where most of our calls start. The houses here run from older bungalows and Spanish-style homes on flat blocks to postwar ranch houses and homes stepped into the hills, and nearly every one has a patio slab, a deck or an old patio room out back that the family wishes they used more. Lots tend to be tight, so a sunroom usually has to fit the space between the house and the garage instead of spreading out across the yard.
We do the same work just across the line in East Los Angeles, but inside the city the job almost always starts with what the room will sit on. A slab poured decades ago or a deck built for chairs and a grill has to be checked before I'll talk about glass.

Sunroom additions
On tight city lots, our sunroom additions often tuck into the corner between the house and the garage, so I plan the roof to tie into the house cleanly. We build it on a foundation sized for the room, not on whatever happens to be there.
Patio-to-sunroom conversion
A lot of houses here have a concrete patio out back that only gets used a few weekends a year, and enclosing it is one of our most common calls. We check the slab first and enclose it only once we know it can carry the room.
Deck-to-sunroom conversion
Raised decks on hillside lots can make good sunroom floors, but most were framed for people and furniture, not walls and a roof. We check the posts, beams and footings and strengthen them before we build on top.
Sunroom remodeling
Aluminum patio rooms built decades ago are all over the city, usually with sticky sliders, worn seals and glass that's gone cloudy. We rework the frames and tracks and replace the glass so the room is comfortable to sit in again.
Three season sunrooms
Plenty of families here want a shaded, enclosed spot for mornings and evenings rather than another fully finished room, and a three season room fits that use for less. I'll ask how you plan to use it before I suggest one.
Patio cover installation
Some small backyards here are better served by a solid patio cover than a closed room, especially when the family mostly wants shade. If a cover is the right fit, I'll say so, even though it's the smaller job.
What a sunroom job inside Los Angeles city limits involves
Inside Los Angeles city limits, your project goes through the city's own offices, and the City of Los Angeles website lists the contacts for each department. We find out which office covers your address and handle the permit applications and inspections when your project needs them, and your contract says in writing who's getting the permits. Since the crew can't start until any permits are in hand, that wait usually sets the start date more than anything we do on site. When you're comparing contractors, ask whether they're licensed and insured, as we are, and ask for their city Business Tax Registration Certificate, because the city's Office of Finance requires one from every business working here.
The price mostly follows what you're asking the room to do. It's a lot like choosing between a single-pane slider and a dual-pane one, where the frame looks about the same but the glass changes both the cost and how the room feels, and size, the roof tie-in, any electrical and whether the slab or deck needs work first move it from there. On narrow streets with little parking, getting glass panels and framing to the back of the house takes planning too, which is one more thing I look at on the visit and spell out in the written quote. We see the same mix of streets up in Glendale and Pasadena, and we plan deliveries the same way there.
What Los Angeles lots and older houses mean for your room
Sloped yards are common here, and a slope changes the whole plan, because the room either sits on a raised deck or needs a foundation that steps down with the ground. I look at how the yard drains and where the low side is, since water running toward a new room is a problem you want solved before the walls go up, not after.
Older houses bring their own quirk. Years of putting windows and doors into older openings taught me they're rarely square, and a sunroom wall that meets your house is the same thing on a bigger scale, so we set the frame to the house as it really is so the glass seals and the doors slide the way they should.

I visit, measure and ask
I come out to every job myself, measure the space and check what the room will sit on. I'll ask a lot about how your family plans to use the room, because that decides the type of room before anything else.
You get a written quote
After the visit I send a written quote that covers the room, the glass and any slab or deck work it needs. Take your time with it and call me with questions.
We handle the permits
Once you sign, we take care of the permits that apply to your project before the crew starts. If an inspection is part of it, we set it up.
Our crew builds, then we walk through
Our own crew does the build, with a lead installer running the site. When it's done I come back and walk through the room with you, opening every window and door together.
Sunroom questions from Los Angeles homeowners
How much does a sunroom cost in Los Angeles?
Your own number comes from a free on-site visit, because the biggest swing on a Los Angeles job is usually what I find under the room. A sound slab means the money goes into the room itself, while a cracked slab or an undersized deck adds repair work before we start. The glass you pick and how the roof ties into your house are the next biggest factors, and the written quote lists each one.
Who issues permits for work that affects the street or sidewalk in Los Angeles?
The city's Bureau of Engineering issues permits for private work that affects the public right of way, the street and sidewalk area the city controls. Most sunrooms sit in the backyard, but if your project reaches that area, it goes through the bureau, and we sort that out before work starts.
How do I check if my house in Los Angeles has a historic designation?
Look up your address in ZIMAS, the city's zoning and map database, which shows whether a property has a historic designation or was identified as eligible for one. City Planning points owners there, and it's worth checking before you settle on a design.
Who reviews a sunroom on a historic property in Los Angeles?
City Planning's Office of Historic Resources reviews proposed projects on designated properties and checks them against the Secretary of the Interior's Standards, a national set of standards for work on historic buildings. That only applies if your property holds one of those designations, so we check early, before the design gets far along.
What is the best way to turn an old patio slab into a sunroom in Los Angeles?
Start by finding out whether the slab can carry walls, glass and a roof, because a lot of older patio slabs here were poured for chairs and a grill, not a room. I check its thickness, cracks and any settling at the estimate, and if it's tired we deal with it first instead of building on top of it.
How long does it take to build a sunroom in Los Angeles?
The wait for any permits your project needs is usually what decides when we can start, and the build follows once they're in hand. Room size, any slab or deck repair and the glass order move the time from there, and I'll talk you through what affects yours when I'm out at your house.

Call (213) 340-1547 or send the form with your address and what you have in mind, since one look at the slab or deck tells us early whether the room or the ground under it comes first.
