Sunroom Contractor in Monterey Park, CA - Patio Rooms Built on Solid Ground
Lightcraft Los Angeles Sunrooms & Patios is a sunroom contractor working in Monterey Park, CA. We turn back patios and decks into sunrooms and screen rooms, and we rework older patio rooms whose glass, frames and sliders have worn out.

Monterey Park homes as we see them on our jobs
What we usually find in Monterey Park is a single-family house with a back patio that's been there a long time, often under an old aluminum cover or a patio room someone added years ago. The neighborhoods run right into the cities next door, so a job here has a lot in common with one in Alhambra or East Los Angeles, but every back yard has its own history once you look under the room.
That history is why I look at the slab or deck before we talk about glass, because a patio poured for a grill and a few chairs wasn't always poured to carry walls and a roof.
Services in Monterey Park, CA
Patio-to-sunroom conversion
Plenty of houses here already have a covered back slab, so a patio-to-sunroom conversion is often the simplest way to add a room. I check the slab and the cover's posts first, because we only build on what will hold the new walls.
Three season sunrooms
If you want a bright spot for family dinners and weekend afternoons rather than an extra bedroom, three season sunrooms give you glass and screens without building a fully insulated room. We talk through how you'll use it first, because that's the choice people regret getting wrong.
Four season sunrooms
When the room has to work as a home office or a place for visiting family to stay, a four season sunroom is built and insulated like part of the house. That usually means tying into the house's electrical and heating and cooling, which we plan from the first visit.
Sunroom remodeling
Older patio rooms around here often have fogged glass, sliders that drag and seals that have given up. I spent years on window and door work, so we replace the glass and rework the tracks and frames instead of tearing out a room that's still sound.
Deck-to-sunroom conversion
Some homes here have a raised wood deck off the back door instead of a slab. A deck built for chairs isn't built for walls and a roof, so we check the framing and footings and strengthen them before any room goes on top.
Patio cover installation
If the old cover over your patio is sagging or rusting and you're not ready to enclose the space, we can put up a new one. We can size the posts and beam so walls can go in later if you decide you want a room.
Working in Monterey Park: permits, licenses and what sets the price
Building or changing a structure in Monterey Park goes through the city's One Stop Building Permit Center, and the permit is usually what sets the pace at the start. Over-the-counter service only covers permits that need no plan check, so a sunroom with drawings waits for plan review, and once the plans are approved the city wants certain clearances done, and sometimes fees paid outside the city, before it issues the permit. While you're checking us out, look for two things, a California contractor license from the state license board and a Monterey Park business license, which the city requires even of contractors from other cities who come in for a single job.
We're licensed and insured, we find out which office covers your address, and we handle the permit applications and inspections when your project needs them, with your contract saying in writing who's getting the permits. The price moves with the size of the room, whether it's a three season or four season room, the glass and frames you pick, any work the slab or deck needs first and whether the room gets lights or heating and cooling, while the build schedule mostly turns on the permit and the materials you choose. The written quote I send after my visit puts your own number on all of that, the same way we do it for homeowners in Pasadena and El Monte.
What we run into on Monterey Park patios and older sunrooms
A lot of the patio rooms we're called to here have been up for years, and the trouble usually shows up at the glass and the tracks first. It's the same thing I saw installing sliding doors, where a door that drags usually means a worn roller or a frame that's shifted out of level, so I check whether the room or the slab under it has moved before blaming the glass. If the slab has cracked or settled, we deal with that first, because new glass in a frame that's still moving just starts sticking again.
The other call we get is from families who simply want more use out of the back yard. Before we talk materials, I ask who's going to be out there and when, because a room built for the wrong use is the one people end up regretting.

How it works when you call us about a Monterey Park sunroom
Call or send a message
Call (213) 340-1547 or use the request form, and we'll get back to you to set up a visit. It helps to tell us what's out back now, a slab, a deck or an older room, so I know what to look for.
I visit and check the base
I come out myself, measure, and take a close look at the patio, slab or deck the room will sit on. I'll ask a lot about how your family plans to use the room, because that decides what kind of room we build.
You get a written quote
After the visit I send a written quote that lays out the room type, the glass and frames and any base work. Take your time with it and call me with any questions.
We handle the city permits
Once you sign, we apply to the city for the permits your project needs, and your contract says in writing who's getting them. If the room needs plan review, the build date follows the city's approval, so I'll keep you posted on where it stands.
We build and walk through
Our own crew builds the room, with a lead installer running the site and the city's inspections along the way. When it's done, I come back and walk through every slider and seal with you.
Monterey Park sunroom questions we hear
How do I get a permit for a sunroom in Monterey Park?
You get it from the city's One Stop Building Permit Center, which handles permits to build, alter, repair or move any building or structure in Monterey Park. The city's building code exempts a few items, and we check your project against that list rather than guess. When your project needs a permit, we handle the application and the inspections.
Do I need a permit to replace the windows in my old sunroom in Monterey Park?
Yes, the city names window and door change-outs as work that needs a permit. That covers a lot of sunroom remodels, since swapping old windows or a worn sliding door is exactly that kind of change-out, so we put it in the permit plan from the start.
Does adding lights or air conditioning to a sunroom need a separate permit in Monterey Park?
Yes, electrical and mechanical permits are separate from the building permit, with electrical covering lighting and mechanical covering heating and air conditioning. The city can bundle them with the building permit into what it calls a combo permit, so a four season room with lights and cooling can move through together.
Does my sunroom contractor need a California state license?
Yes, for nearly any sunroom, because the state requires a license when a project needs a building permit or costs $1,000 or more in labor and materials. A bigger job can't be split into pieces under $1,000 to get around that, and you can look up a contractor with the Contractors State License Board.
Can I pull a sunroom permit myself as the homeowner in Monterey Park?
Sometimes, because the city may issue a permit to a homeowner as an owner-builder under certain circumstances. Permits for some types of work only go to people licensed by the state for that trade, and the city's permit issuance page links the full list of license categories and what each one can do.
What causes a sunroom to cost more in Monterey Park?
The biggest jumps come from going to a full four season room, adding more glass, and fixing a tired slab or weak deck before we build. What keeps it down is a sound slab we can build right on and a three season room that fits how you'll use it, and the written quote after my visit gives you the number for your house.
