What goes into building a custom sunroom in Baldwin Park?
A custom sunroom in Baldwin Park is a glass room we build onto your house to fit your own patio, deck or slab. The space you already have becomes a room you can sit in, out of the sun, wind and bugs.
Most people who call us have a patio they barely use, or an old cover that never really fit the house, and they're ready for a patio-to-sunroom conversion. The price mostly moves with the size of the room, whether it's a three-season or four-season room, the glass and roof you pick, and whether your slab can carry the room or has to be replaced. The schedule turns on the base work, on ordering parts once the measurements are checked, and on the permit. Before work starts, we check whether your address goes through the city or Los Angeles County, and we handle the permit paperwork when the job needs it. After I measure, you get a written estimate with your own number on it.
How do you know your patio is ready to become a sunroom?
A patio nobody sits on
If the patio sits empty most afternoons because of the sun, the wind or the bugs, you're keeping up space you don't get to use. Walls and glass usually fix that, and every season you put it off is one more season you spend indoors.
Cracks across the slab
Cracks, a raised edge or water pooling by the house usually mean the slab has moved. You want to know that before you plan a room on it, because a slab that keeps moving can open gaps at the edges of whatever sits on top.
Drips and sticking doors
If your current enclosure drips at the edges, fogs between the panes or has doors that drag, it usually wasn't built square or sealed well. Left alone, water works into the frame and the floor, and the repair keeps growing.
Often paired with a custom sunroom
Sunroom construction
For when there's no usable patio or deck and the room has to go up from new ground.
Sunroom remodeling
For a sunroom you already own that leaks, sticks or no longer suits how you live.
How we build a custom sunroom
A custom room starts with what it sits on, so I measure the spot first and look hard at the patio for cracks and buckling before we plan anything. If the slab won't do, I'll say so, and we'll plan a new base instead of building on a problem. Then we work out the room around your house, meaning how the roof meets yours, where the glass goes and whether the room opens into the house. Nothing gets ordered until the measurements are checked, because I'd rather spend an extra hour checking than guess. On the roof, I usually steer people toward a solid, insulated roof over a full glass one, since glass overhead lets in the most heat and glare, and a solid roof keeps the room usable on a summer afternoon. Our crew then sets the base, frames the room, sets the glass and seals the edges, because a room that's square and sealed is a room you'll actually use.
Some jobs start with nothing to build on, and those go through our sunroom construction work, new base and all. If you already have a room that leaks or doesn't fit the house, sunroom remodeling may get you there without starting over.
Three-season room
This suits you if you want shade and shelter from wind and bugs and don't plan to heat or cool the room. It's a lighter build with simpler glass, so it usually costs less.
Four-season room
This suits you if you want a room you use every month, with insulated walls and roof, better glass and its own heating and cooling. It costs more and comes with more paperwork, and at the estimate I'll tell you which type fits how you'll use it.

Building in Baldwin Park since 2017
I grew up working summers on crews building patio covers and sunrooms, and I opened this business here in 2017. After nine years, we know the slabs, patios and tired old enclosures people deal with in Baldwin Park and the cities around it.
Licensed and insured for your build
We're licensed and insured. In California, contractors are licensed by the Contractors State License Board, the state office that licenses and regulates the construction industry, and a room tied into your house is real construction.
On a custom room, the base and the measurements decide how everything else goes, so request a visit on our contact page and I'll start with what's under your patio.
What happens after you call about a custom sunroom?
Call and I come out
Call (626) 869-2042 or send the form, and I'll come out to look at the spot, measure it and check the slab or deck underneath. Expect me to spend real time on the base, because that's what everything else sits on.
Talk it through, get it written
We go over the room type, the glass and whether the room opens into the house, and then you get a written estimate. You'll have the room we talked about and its price on paper before you decide anything.
Permits, then our crew builds
Once you're ready, we sort out what the city or county asks for at your address, and in the city that goes through Baldwin Park Building and Safety, which is open Monday through Thursday, 8 am to 5 pm, and closed Fridays. When that's settled, our own crew builds the room.
Common questions
What is the best way to choose between a three-season and a four-season sunroom?
Choose a three-season room if you'll use it in spring, summer and fall, and a four-season room if you want it year round. A national home-services guide, writing about moderate and cold climates, describes three-season rooms as uninsulated, often with single-pane windows, while four-season rooms add better insulation, double- or triple-pane windows and their own heating and cooling. In California, the California Energy Commission counts heating and cooling a space that wasn't conditioned before as an addition, so a four-season room gets planned around the state's addition rules from the start.
How much does a custom sunroom cost near Baldwin Park?
A sunroom addition in Los Angeles usually costs about $23,000 to $66,000 per job. That's the going range for the area, not our price. Where your room lands depends mostly on its size, the room type, the glass and roof, and whether your slab works or needs replacing, and the written estimate after I measure gives you your own figure.
Who issues building permits for a sunroom in Baldwin Park?
The city's Building and Safety office issues building permits in Baldwin Park. For an addition that changes the outer shell of the house, the state also requires an energy compliance form with the permit application. The plan has to meet the city's zoning standards for your home's zone too, so that's where our planning starts.
How much can a contractor ask for up front in California?
A contractor can't ask for or accept a down payment of more than $1,000 or 10 percent of the total contract price, whichever is less. That's the state licensing board's rule for all home improvement projects in California. Any other payments have to be listed clearly in the contract and based on work done or materials delivered, so ask to see that schedule before you sign.
How do I know if my patio slab can hold a sunroom?
Your slab has a chance if it's flat, solid and close to new, and a slab with a lot of cracks or buckles usually isn't. One sunroom maker's install guide prefers a new slab or deck and says an existing one should be in like-new condition, because a cracked or buckled slab is unsuitable and could lead to leaks. A cracked patio may mean starting on a new slab or deck.
What counts as a sunroom in California?
A sunroom is a one-story room attached to a house with glass over 40% of the gross area of its outer walls and roof. That's California's residential code definition, as a Milpitas city building handout quotes it.
