Sunroom contractor in South Pasadena, CA - rooms that suit older homes
Lightcraft Los Angeles Sunrooms & Patios is a sunroom contractor working in South Pasadena, CA. We turn patios and decks into sunrooms, build patio covers and enclosures, and rework older sunrooms whose glass, frames or seals have worn out.

What sunroom work looks like in South Pasadena
South Pasadena is a small city of flat streets and hillside lots on the west side of the San Gabriel Valley, with Pasadena to the north and Alhambra to the east. It's mostly homes, and a lot of them have been standing a long time.
Most calls we get here start in the backyard. On the flatter streets it's usually a concrete patio off the kitchen or family room that the owner wants to get more use out of. Up the hills it's more often a raised deck off the back of the house, or a sunroom somebody added decades ago whose sliders now drag and whose glass has gone cloudy. People here also want the new room to look like it belongs to the house. Older houses mean older patios, decks and walls to tie into, so on every job here I look at what the room will sit on and attach to before we talk about glass.
Services in South Pasadena, CA
Patio-to-sunroom conversion
On the flatter streets, the back patio is usually an older slab that's been patched or has sunk a little over the years, and that's what a new room would sit on. For a patio-to-sunroom conversion we check the slab first and repair or replace what needs it, so the frame and glass go onto something level.
Deck-to-sunroom conversion
Hillside lots here often have a raised deck off the back of the house, and it's one of the most common spots people want to close in. For a deck-to-sunroom conversion we find out first whether the deck can carry a room, and we don't build on one that can't.
Sunroom remodeling
Some of the sunrooms we see here were added a long time ago, and the trouble usually shows up as foggy glass, sliders that drag and seals that let dust and water in. We rework the glass, tracks and seals, and the frame if it needs it, much the way I'd bring a tired sliding door back to life.
Sunroom design
Older houses here have their own rooflines, trim and window styles, and a room that ignores them looks bolted on. We draw the room around your house and around how your family will use it, so you settle on a three-season or four-season room before we ever talk about finishes.
Patio enclosures
Plenty of homes here already have a covered patio, and closing it in with glass or screens is often the shortest path to a room you'll use. We check the posts and beam that are already there, because an enclosure hangs a lot of weight on framing that was only built to hold up a roof.
Patio cover installation
On smaller lots where a full room would crowd the yard, a cover over the patio gives you a shaded, dry spot to sit and keeps the yard open. We tie the cover into the house so it lines up with the existing roof edge, which takes some care on older homes where nothing is quite square.
Working in South Pasadena: permits, licenses and what moves the price
In South Pasadena, the city's Building Division issues the permits for new structures, and its list of projects that need one includes additions and decks, so plan on a permit for most sunrooms. Most exterior changes here also need the city's design approval, and that review, more than the build itself, usually decides when we can start. Before you hire anyone, ask for their license from the California Contractors State License Board and their South Pasadena business license, because the state and the city both require them for a job like this.
We handle the permit applications and inspections your project needs, and your contract says in writing who's getting the permits. The price here mostly turns on what the room sits on, whether you want a three-season room or a fully closed four-season room, how much glass it has and how the new roof ties into an old house. When I come out I measure, look at the slab or deck and follow up with a written quote, so your figure comes from your own backyard. We do the same work across the cities around Los Angeles, from Pasadena down to Huntington Park.
What older houses and hillside lots mean for your sunroom
Older houses are rarely square anymore, and the wall a sunroom ties into is the part I watch closest. I learned that in the years I spent setting windows and sliding doors before I started building sunrooms in 2013, because an opening that leans a little out of plumb will make a door bind no matter how good the door is. So on an older house we measure that wall at several points and build the frame to fit it, which lets the glass sit evenly and the seals close all the way around.
Hillside lots take their own planning, since getting glass panels and framing from the street to the backyard can mean steps, slopes and narrow side yards. We work out where materials will be staged and how they'll be carried before build day, so nothing gets set down on a slope.

I come out and look
I come out myself to look at the slab or deck, measure the wall the room ties into and talk through how your family will use the space. Most of my questions are about use, because a room built for the wrong use is the one people regret.
You get a written quote
After the visit I send a written quote that spells out the room, the glass and any slab or deck repair it needs first. Once you sign, your contract says in writing who's getting the permits.
We sort out the permits
We handle the permit applications and inspections the job needs. In South Pasadena this step also waits on the city's design review, so it's the part of the schedule that moves the most.
Our crew builds the room
Our own crew builds it, with a lead installer running the site. When it's done I come back and walk through the room with you, and we try every door and slider together.
South Pasadena sunroom questions
How much does a sunroom cost in South Pasadena?
The cost comes down to what the room sits on, what kind of room you want, how much glass it has and how the roof ties into your house, so I don't give a number until I've seen the backyard. A sound slab or deck keeps the cost down, while one that needs repair, a fully closed four-season room or a design that changes more of the outside of the house pushes it up. I'll measure on the visit and send you a written quote.
Does a sunroom in South Pasadena need design approval?
Usually, yes, because the city requires design approval for most exterior changes to homes, and a sunroom changes the outside of the house. Depending on how much the room changes and what kind of change it is, that review can be a sign-off from city staff or can go to a public hearing, which usually means more time. We draw the room around your house's lines from the start, so the plans begin in keeping with the house.
How do I find out if my South Pasadena house is on the historic inventory?
Ask the city's Planning and Building department, which can tell you whether your house is listed. About 2,500 properties are on the city's Cultural Heritage Inventory, and most homes 50 years or older are on it, so there's a good chance an older house here is. Being listed only affects exterior work, which then has to follow the city's standards and guidelines, and since a sunroom is exterior work we plan it with that in mind.
When does a contractor need a state license to build a sunroom in California?
A contractor needs a state license when the project needs a building permit, uses any additional workers, or has contracts totaling $1,000 or more in labor and materials, and a sunroom almost always meets all three. The board licenses anyone who builds or alters structures in California, with a few listed exemptions, so ask for the license before you sign. We're licensed and insured.
Does a contractor based outside South Pasadena need a city business license?
Yes, anyone doing business inside South Pasadena city limits needs a city business license, and the city specifically says contractors based outside the city have to apply too. That includes us, since we're based in Los Angeles, so it's a fair thing to ask any contractor about before work starts.
What is the best way to turn a raised deck into a sunroom in South Pasadena?
Start with the deck, not the glass, because a sunroom puts a roof, a frame and walls of glass on framing that was built for people and furniture. On hillside lots the downhill posts are usually the tall ones, so I check them along with the beams and footings, and we reinforce or rebuild before anything else goes on. Then we pick the room for how you'll use it, since a four-season room with heavier glass asks more of a deck than a three-season room does.
