Sunroom contractor in El Monte, CA - turn your backyard patio into a real room
Lightcraft Los Angeles Sunrooms & Patios is a sunroom contractor based in Los Angeles that builds sunrooms, patio enclosures and screen rooms in El Monte, and reworks older rooms that have started to leak or stick.
El Monte homes and the backyards behind them
El Monte is mostly blocks of single-story houses on flat lots, a lot of them from the postwar decades, with a concrete patio by the back door and often an aluminum cover someone added years ago. Families here use the backyard hard, for meals, birthdays and kids, so most calls we get are about making that space usable on hot afternoons and cool evenings. The houses look a lot like what we work on in Monterey Park and West Covina, though each city runs its own permit counter.
Most rooms we build here go on top of an existing patio or under an old cover, so what's already in your yard decides a good part of the job.
Services in El Monte, CA
Patio-to-sunroom conversion
Plenty of El Monte backyards already have a concrete patio off the kitchen or family room, which makes it the natural spot for a room. We check that slab first, then frame and glass the room on it, or fix the slab before anything goes up.
Patio enclosures
If your patio already has a solid roof over it, closing it in can be the simpler path to a room you use most of the year. We set walls, windows and a door under the cover once we've checked that the posts and beam can carry them.
Sunroom remodeling
A lot of the older enclosures we see here have sliders that drag, fogged glass and seals that let water in at the corners. Our sunroom remodeling work replaces tired glass, tracks and roof panels, which is the same work I did for years on windows and doors.
Four season sunrooms
When you want the room comfortable on a hot July afternoon and not just in spring, a four season room with insulated glass and an insulated roof is the one to look at. We'll talk through whether you need that or whether a lighter room fits how you'll actually use it.
Screen room installation
Some families here mostly want a shaded, bug-free spot for evenings outside, and a screen room does that for less than a glass room. We build it on your patio with a solid roof, and we can talk about framing it so glass can go in later.
Patio cover installation
Many El Monte patios still sit under aluminum covers that have sagged or rusted out at the posts. We replace them with a new cover sized for your patio, and if a room is in your plans, we can build it to carry walls down the road.
Working in El Monte: permits, paperwork and what sets the price
For a sunroom on your lot, the city's Building and Safety office is the main stop for plan review, permits and inspections, and the counter staff say which other departments need to see your project. That review usually sets the start date, because our crew doesn't build until the plans are approved, so we find out which office covers your address and handle the applications and inspections for you. If any part of a job reaches onto public property, the Public Works Department has to issue its own permit first, and the contractor has to show a valid City of El Monte business license, a contractor license and liability and workers comp insurance naming the city, which are fair things to ask anyone you're thinking of hiring to show you. We're licensed and insured, and happy to show it.
As a sunroom contractor based in Los Angeles, CA, we're out this way often, along with nearby Alhambra and down in Downey. What moves your price is the kind of room, its size, the glass and roof you pick, and whatever the slab or deck needs before we build on it. What moves the schedule is mostly permit review and how much prep the base needs, and you get your own figure in the written quote after I've seen the site.
What El Monte heat and ground ask of a sunroom
Summer afternoons get hot here, and a glass room facing west can turn into an oven if the glass and roof are wrong for it. That's the lesson I brought over from windows, where the glass does most of the work, so we match the glass coating and roof insulation to which way the room faces and how much you'll be in it in July.
The ground matters just as much. The city designs for strong earthquake shaking, Seismic Design Category D, unless a soils report for your lot sets a different one, and a room full of glass has to sit on footings and a slab that can hold it through that. So I check your slab for cracks, settling and soft spots before we talk about anything else, and if it's tired, we fix or replace it first instead of setting glass walls on top of a problem.

Call or send a message
Call (213) 340-1547 or use the form and tell us a little about your patio or deck. We set up a time for me to come out.
I come out and measure
I look at the patio, slab or deck myself and ask a lot of questions about how your family will use the room. It helps to have a rough idea of what you want the room for, even if you're not sure on the details.
Review your written quote
You get a written quote that spells out the room, the glass and roof, and any work the base needs first. Take your time with it and call me with questions.
We take care of permits
Once you sign, we file the permits your project needs with the city and line up the inspections, and the build starts after plan review. Your contract says in writing who's getting the permits.
Build and final walkthrough
Our own crew builds the room, with a lead installer running your site. When it's done, I come back and walk through it with you, doors, tracks and glass included.
Sunroom questions from El Monte homeowners
How much does a sunroom cost in El Monte?
The price comes down to the kind of room, its size, the glass and roof you choose, and what your patio or deck needs before we build on it. A screen room on a sound slab costs far less than a four season room on a slab that has to be replaced, and city permit fees come from the Building Division's posted schedule, which went up for the 2026-2027 year. I come out, measure and send a written quote so you see your own number.
Which building code applies to a sunroom in El Monte?
A sunroom submitted for permit now has to be designed to the 2025 California building codes, which the city enforces as of January 1, 2026. An application filed before that date can stay on the code in effect when it was filed while its plan check is still active, but once that plan check expires, it takes a new application under the new codes. We design your room to the current code from the start.
How do I apply for a sunroom permit in El Monte?
You apply in person at Building and Safety, which takes walk-ins with no appointment, because the city's online portal only handles residential electrical panel upgrades and water heater change outs. The office has separate building, electrical and mechanical, and plumbing and sewer applications on its permit applications page. When your project needs permits, we handle the applications for you.
How do I check if my house is in the City of El Monte for permits?
Building and Safety's permit applications page has a link that tells you whether an address falls within the city's jurisdiction. It's worth checking, because a mailing address doesn't always match the city line, and the city line decides which office reviews your room. We find out which office covers your address before we file anything.
What is the best way to build a sunroom roof for El Monte wind?
Build the roof, posts and their connections to the house for the city's design wind speed of 95 mph as a three-second gust, Exposure B, which is the setting for built-up neighborhoods with houses and trees around. That load is a big reason we pay close attention to how the room ties into your house, the same way a sliding door frame has to be anchored right before the glass goes in.
Can I enclose my old aluminum patio cover in El Monte?
Sometimes, but only after we check it, because a lot of older covers were built for shade, not for walls, glass and the wind and earthquake loads the city designs for. If the posts, beam and footings hold up, we can enclose it, and if they don't, we replace the cover as part of the job. It's one of the first things I look at on the visit.
