Four season sunrooms in Wildomar CA - a room you can use in July and January
Patio too hot in summer and too cold in winter to use? We build a heated and cooled room you'll sit in all year.

Is a four season sunroom right for your Wildomar home?
A four season sunroom is a fully enclosed room with all-weather windows and its own heating and cooling, so your house in Wildomar, CA gains a room you can use in August and January, not just on mild spring days.
Most people who call me have a patio or deck that sits empty half the year because it's too hot or too exposed, and they want more out of it but aren't sure where to start. Size moves the price most, and a larger room that needs a foundation and heating and air conditioning sits toward the high end, while the schedule turns on the permit, the city's inspections and how much of your roof, walls and floor the new room ties into. Before you sign anything, you get a written estimate with each part of the job listed in plain language, so you know exactly what you're paying for.
How we build a four season sunroom
I start every four season room by planning the windows, insulation and heating and cooling together in the first drawing, because the whole point is comfort all year and those three only work if they work as one. Highly insulated windows and insulation in the walls, floor and roof are what make a sunroom efficient, and they're much easier to put in while the room goes up than to add later, when it can often cost more. Once the plan is set, we get the permit, prepare the base, frame the walls, tie the new roof into your house, set the windows, insulate, run the heating and cooling, finish the inside and clean up.
Not every patio needs to be a full year-round room. We also build three season sunrooms and patio enclosures, and I'm happy to sketch either one next to a four season room so you can see how they compare. The main difference is heating and cooling, which I cover in the questions below.
Why Wildomar homeowners call Daylight Wildomar Sunrooms & Patios for four season rooms
I measure and explain the options
I'm the one who comes out to look at the job, measure and talk through the options, and I'll ask plenty of questions about how you plan to use the room. Our own crew does the building and I check in as it goes up, so the person who explained the plan is the one keeping an eye on it.
A former roofer on the tie-in
I roofed houses for years before I started this business in Wildomar in 2017, and that's still how I look at every sunroom. The new roof has to meet your house roof without opening a path for water, so that seam is the first thing I study.
Planned for local termite risk
Wildomar's building design criteria rate the termite hazard here as very heavy. That's why we go over what the frame and floor are made of in the first drawing, not after the walls are up.
Licensed, insured and handling permits
We're licensed and fully insured, and when a job needs a permit we handle the paperwork and inspections with the city or county while I explain each step. The city's permit application asks for a signed statement that the builder is licensed under the state's contractor law, so it's fair to ask any builder who will be signing it.
On a four season room, the thing that matters most is getting the heating, cooling and windows into the plan before anything gets built. Send us your project details or call (951) 290-7274, and it helps if you know roughly how big you want the room, whether it'll be heated and cooled and whether the work means cutting into an existing slab.
Get a written estimate for your four season room
We reply within one business day to set up a visit. I'll come out, measure and talk through what you want from the room, and the estimate is free at your property with no obligation to go ahead.
Four season sunroom ideas
Questions before you build a four season sunroom
How do I choose between a four season and a three season sunroom?
It comes down to whether you want the new room heated and cooled. Three season rooms and enclosed patios have neither, and they use uninsulated windows or screens, so they suit the months when the weather cooperates, while a four season room is built to be lived in all year. I'll ask how you plan to use the space before we pick.
How much does a four season sunroom cost in the Riverside area?
A sunroom in Riverside, California usually costs about $17,000 to $120,000 per project, which is what the area's market runs, not our price. Where your room lands depends on the size and the other things I mentioned up top, and your written estimate gives you your own figure.
Who issues building permits for a sunroom in Wildomar?
The city's Building and Safety Department issues construction permits for projects that meet code, including building, electrical, plumbing and mechanical permits. We sort out with you what your room needs before work starts, so nothing gets built ahead of the paperwork.
Can a four season sunroom be built on my existing patio slab?
Sometimes, but before anyone saw cuts or breaks into an existing slab, the first thing to find out is whether it's a post-tension slab, one with steel cables pulled tight inside the concrete. Another California city's building handout warns that cutting one of those cables can be very dangerous and expensive to repair. Let us know when you call if the room means cutting your slab.
Do fire hazard zones affect building a sunroom in Wildomar?
They can, because the city says its updated Fire Hazard Severity Zones affect defensible space, building codes and real estate disclosure requirements in Local Responsibility Areas. With limited exception, the same wildfire building and defensible space rules apply in any zone from Moderate to Very High, so even a Moderate rating matters for how the room is planned. For questions about your property's zone, call the Riverside County Fire Department Office of the Fire Marshal at (951) 955-4777.
How long does it take to build a four season sunroom in Wildomar?
The timeline turns on the size of the room, the design and the permit, so I talk you through the schedule once I've measured and we've settled on a plan. During the build the city inspects at stages such as foundation, framing, electrical and final, and the next step waits on each one. Crews can work Monday through Saturday from 6:30 am to 7:00 pm, with no construction on Sundays or city holidays.
Other ways to get more from your patio
- Three season sunrooms
A good fit if you mostly want shelter for the mild months and don't plan to run heating or cooling out there.
- Patio enclosures
For closing in the patio you already use so the wind, dust and bugs stay outside.
