What does it take to add a four season sunroom in Baldwin Park?
A four season sunroom is an insulated, temperature-controlled room built onto your house in Baldwin Park, so you can use it on summer afternoons and cool winter evenings and it works as part of your home instead of a porch.
Most people who call me have a slab patio or a deck they like and want to use every month, not just on mild days. If spring and fall are enough for you, a three season sunroom may do the job. The price of a four season room moves with its size, the glass and materials, and what it sits on. The schedule depends on whether it's a kit or built custom, how much work the slab or deck needs first and what the city or county asks for. Your written estimate puts all of that together for your room.
How do you know it's time for a four season room?
Patio too hot by noon
You use the patio in the morning and give up on it by midday because the sun bakes it. A cover gives you shade but can't hold cool air, so the space stays a morning-only spot until it's closed in and cooled.
Screen room empty in winter
A screened or three season room is nice on mild days and then sits unused on cold evenings because there's no way to heat it. If you want it year-round, it needs insulation and its own temperature control, and every winter you wait is another season you're not using it.
Drafts at the edges
You feel air at the base of an old enclosure or see water where the wall meets the slab. That usually means the room isn't square or sealed where it meets the house, and water left there works its way into the floor and framing.

Worth a look if you mostly want the room on mild days and don't plan to heat or cool it.
Patio enclosures
A good fit when you already have a solid patio cover and want walls and glass added under it.
How we build a four season sunroom
First I measure the spot and check the slab or deck underneath, because every part gets ordered off those numbers. Then we walk you through keeping the room closed off from the house with its own heating and cooling, or opening it up as part of your living space, and we pin that down before any drawings start, since each choice changes the plan. One California city's sunroom handout tells crews to check whether a slab is post-tension, held by tensioned cables called tendons, before cutting into it, because cutting a tendon can be very dangerous and expensive to repair. Once the drawings and glass are settled and the parts arrive, our crew frames the room, seals it at the edges and cleans up.
Not every patio needs a fully conditioned room. A three season sunroom gives you glass and shade for the mild months without the heating and cooling, and patio enclosures close in a covered patio you already have, which can make sense when the cover is in good shape.
Closed off from the house
This suits you if you want a room you can shut and heat or cool on its own, with your existing doors and windows left where they are. Its heating and cooling stay separate from the rest of the house.
Opened up to the house
This suits you if you want a real extra room that flows into the kitchen or family room. It's built like any other part of the house, so there's more to plan up front.

I measure and check myself
I come out, measure the spot and check the slab or deck before anything gets ordered, and our own crew does the build. A room that's square and sealed at the edges starts with numbers you can trust.
Building rooms here since 2017
I opened the business in Baldwin Park in 2017, and we work in the cities around it, including West Covina, El Monte, Azusa and Rosemead. We see a lot of slab patios and older covers that people want closed in, so that's the work we know.
Licensed and insured in California
We're licensed and insured. The state's Contractors State License Board caps a contractor's down payment at $1,000 or 10 percent of the contract price, whichever is less, and any other payments have to be listed in the contract and tied to work done or materials delivered.
Room sized to your lot
Baldwin Park limits how much of a lot buildings can cover, from 40 percent in the R-1-7,500 zone up to 60 percent in R-3, so the room has to fit your lot as well as your patio. How an attached sunroom counts is the city Planning office's call, so we find that out for your address before drawings start.
On this job the base and the measurements matter most, so that's where I start. Tell us about your patio or deck and I'll come take a look.
What happens after you call about a four season sunroom?
Call or send the form
Call (626) 869-2042 or fill out the form, and we'll set a time for me to come to your house. It helps to tell us whether the room would sit on a slab, a deck or under an existing cover.
I measure and check underneath
I look at the spot, measure it and check the slab or deck the room will sit on. I'd rather spend an extra hour here than guess.
We plan it and price it
We talk through the room type, the glass and whether it opens to the house, and then you get a written estimate. You see the price for your room before anything gets ordered.
Permits first, then the build
Once you're ready, we sort out what the city or county asks for at your address, and then our crew builds the room. The city's building counter is open Monday through Thursday, 8 am to 5 pm, and closed Fridays, so city paperwork moves on those four days.
Common questions
How much does a four season sunroom cost in Baldwin Park?
Adding a four season sunroom usually costs about $200 to $400 per square foot across the US, and that's a national figure for the work, not our price. Size, materials and the foundation move it most, so a room on a deck that needs new footings costs more than one on a sound slab. Your written estimate gives you the figure for your room.
What is the difference between a Category IV and a Category V sunroom?
A Category IV sunroom has its own heating, cooling or both and keeps the house's existing doors and windows in place, so it stays separate from the home, while a Category V sunroom is basically a regular room addition that doesn't have to be kept separate. A Category V room follows the same requirements as any other addition, and in California that includes the state Energy Code's energy efficiency requirements for additions. It's the closed-off or opened-up choice described above.
Can I build a sunroom on my existing deck?
Yes, a sunroom can go on a deck, but the deck will typically need added beams, posts or footings to carry the room's weight. A local structural engineer can tell you whether your deck is suitable, so that check comes first. I look at the framing underneath on my first visit, so you know early what we're working with.
Who issues building permits for a sunroom in Baldwin Park?
The city's Building and Safety Division issues building permits in Baldwin Park, and it also handles plan checks and inspects construction sites. Before work starts, we check 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.
How long does it take to build a four season sunroom?
A prefab sunroom kit takes 1 to 2 weeks to build, while a custom-built sunroom takes 2 months or more. If you're on a tight schedule a kit is worth a look, and if you want a room built to fit your house, plan for the longer build. I'll tell you at the estimate what your slab or deck needs before the build can start.
What is the best way to keep a sunroom from getting too hot?
Start with the glass, because its Solar Heat Gain Coefficient, or SHGC, rates how much of the sun's heat gets through on a scale from 0 to 1, and a lower number blocks more. On a wall that takes the afternoon sun, a lower number is worth asking for. We go over the glass choices with you when we plan the room.
