Sunroom contractor work in Baldwin Park, CA
Baldwin Park Sunrooms & Patios is a sunroom contractor in Baldwin Park, CA, and we've been building rooms onto houses here since 2017. Most calls start with a patio, deck or slab you'd use more if it had walls and a roof. The price mostly turns on the room type, its size, the glass, whether it opens into the house and what the base under it needs. The schedule turns on that base and on what the city or county asks for at your address. I measure your spot in person, and you get a written estimate with your own figure. Here are the 16 kinds of work we do.
Sunroom additions
A sunroom addition is a new glass-walled room built onto your house, with its roof tied into yours. It's for homeowners who want more living space and more daylight in the same spot.
Four season sunrooms
Want a room you can sit in any month? A four season sunroom is insulated and sealed like the rest of the house, so it can be heated and cooled along with it.
Three season sunrooms
A three season room is closed in with windows but not insulated like the house, so it costs less than a four season room. It suits people who don't plan to heat the space.
Patio enclosures
Got a patio cover you barely use because of bugs, wind or dust? We close in the sides with screens, windows or panels so the space under it works as a room.
Custom sunrooms
We design a custom sunroom around your house and lot instead of a standard size, with the roof line, glass and doors picked to match. It fits houses with an odd footprint or owners with a clear picture of the room.
Sunroom construction
Our own crew handles the full build, from the base and framing to the glass, roof and trim. You deal with one business from the first measurement to the last cleanup.
Sunroom remodeling
If your sunroom leaks at the edges, runs hot or just looks dated, we can replace the glass, panels, roof or floor. We keep what's still sound so you're not paying to rebuild it.
Screen room installation
A screen room keeps bugs out and lets the air through, and it's the simplest way to close in a patio. It's for people who want to sit outside, not heat or cool the space.
Patio-to-sunroom conversion
We turn an existing concrete patio into a walled, roofed sunroom, using the slab you already have when it can carry the room. That's often where a backyard has the most room to gain.
Deck-to-sunroom conversion
A raised wood deck can become a sunroom, but only if its posts and framing can hold the weight of walls and a roof. We look at what's under it and build from there.
All season rooms
What's an all season room? It's a fully insulated sunroom, heated and cooled so it works as an everyday room like a den or an office.
Enclosed patio rooms
We wall in a covered patio with windows, doors and a proper floor so it works as a room for meals, guests or a place for the kids to play.
Solarium installation
A solarium has glass in the roof as well as the walls, so you get as much daylight as a room can hold. The glass choice matters more here, because that much glass overhead lets in a lot of heat.
Patio cover installation
We build patio covers, attached to the house or freestanding, that put shade over a slab or deck. A cover built right can also be the first step toward closing the space in later.
Sunroom design
Not sure what the room should look like? We work out the size, roof shape, glass and door placement with you before anything is ordered, so the room fits the house.
Vinyl sunrooms
Vinyl sunrooms use vinyl framing that never needs painting, which suits homeowners who want a room with little upkeep. We'll tell you plainly where vinyl fits your room and where it doesn't.

Baldwin Park backyards, slabs and patios
Baldwin Park is where we're based, and it's a city that spends a lot of time outdoors. Morgan Park sits beside the Community Center and Senior Center, with an outdoor amphitheater, splash pads and paved paths, and Barnes Park has picnic shelters and a lighted soccer field. Walnut Creek Nature Park keeps a stone picnic shelter and native plants close to home, and the Baldwin Park Historical Museum holds the stories of the people and events that shaped the city.
On jobs around the city we see plenty of concrete patios, older patio covers and backyard slabs that could be doing more. The state's EQ Zapp tool shows whether a lot sits in a mapped earthquake hazard zone, including ground that can briefly act like quicksand in a quake, or whether the area hasn't been evaluated yet. When you're ready to make more of your own yard, we're right here in Baldwin Park and in the cities around it.

About usFrom your first call to the finished room
Call or send the form
Call (626) 869-2042 or send the form, and we get back to you within one business day. Tell us what's out back now, whether it's a slab, a deck or a patio cover, and what you'd like the room for. That gives me enough to plan the visit.
I measure and check the base
I come out to your house, look at the spot, measure it and check the slab or deck underneath. Then we talk through the room type, the glass and whether the room opens into the house. You get a written estimate after that, free and with no obligation.
Permits, then the build
Once you're ready, we find out whether your address goes through the city or Los Angeles County, and we take care of the permit paperwork when the job calls for one. Then our own crew builds the room, starting from the base we checked at the visit.
Final check and cleanup
When the room is up, we go through it with you and look at the corners, the doors and the sealed edges, because a room that's square and tight is one you'll use. Any inspection the permit calls for gets scheduled, and we clean up before we leave.

Common questions
How much does a sunroom cost in Baldwin Park?
The cost depends on the room you pick, its size and what the base under it needs, so there's no fair number until the spot is measured. A screen room usually costs the least and a fully insulated four season room the most, with three season rooms in between. Glass in the roof, a door into the house and slab repair all push it up.
Is it cheaper to enclose my existing patio than to build a new sunroom addition?
Often it is, because a sound slab or patio cover saves you from paying for a new base or roof. That only holds if what's there can carry walls and glass. A cracked or out-of-level slab needs work first, and that narrows the difference.
How long does it take to build a sunroom in Baldwin Park?
The time mostly depends on the permit review and the condition of the base, more than on the framing and glass. If plans have to be checked by the city or county, that comes first, and a slab or deck that needs repair adds time before the room goes up. We'll walk you through the order of work at the estimate.
Does a sunroom contractor in California need a license?
Yes, a sunroom job almost always needs a licensed contractor, because California requires one when the work needs a building permit, uses employees or totals $1,000 or more in labor and materials. A bigger job can't be split into smaller contracts to stay under that line. Contractors from outside Baldwin Park also need a city business license to work here, and we're licensed and insured.
Can my existing concrete patio hold a sunroom?
Sometimes, and the only way to know is to check the slab before anything gets ordered. We look at its cracks, its level and how it was built, because walls and a roof put weight on it that a patio was never asked to carry. The same goes for a deck you want to turn into a sunroom.
Do you guarantee your sunroom work?
Yes, our work is satisfaction guaranteed. We check the base and the measurements before anything is ordered, because most sunroom problems start at the slab and at the edges where the room meets the house.
What's the difference between a three season and a four season sunroom?
A four season sunroom is insulated and sealed so it can be heated and cooled with the rest of your house, and a three season room isn't, so it costs less but isn't meant to be heated. We help you choose by how you'll use the room. You can read more about four season sunrooms and three season sunrooms.
Do I need a permit to add a sunroom in Baldwin Park?
The city's Building and Safety Division decides that, since it handles plan checks and inspections for construction in Baldwin Park. An older city notice lists home additions among the jobs that need plans submitted. Some addresses near here go through Los Angeles County instead, so we confirm which office covers yours and handle the paperwork when the job calls for a permit.
