Is a three season sunroom the right fit for your patio?
A three season sunroom closes in your porch or patio with screens or uninsulated glass, so you get a room off the house that isn't heated or cooled. In Twentynine Palms we usually build it onto the slab or patio you already have.
Most people who call Twentynine Palms Sunrooms & Patios about one have a patio they'd use a lot more if it had walls, and they don't need it heated and cooled like a four season sunroom. The price moves with the room's size, screens or glass, the roof, and how much work the base and the wall it joins need before we start. The schedule mostly turns on the city's plan review and that same prep, and your estimate lays out what the price covers and what it doesn't.
How we build a three season sunroom
I start with the two questions that settle most of a three season room, screens or glass, and where the room sits on the house, because those two choices shape everything after them. Once you've signed off, our crew checks and preps the base, frames the walls, ties the roof into the house and flashes that joint so water runs off instead of in, then sets the screens or glass and cleans up. We aim for a room that looks like it belongs to the house, not one bolted onto it.
If the patio already has a cover and you mostly want it closed in, our patio enclosures work may be the simpler route. When the house has an odd roofline or a slab that meets the wall in a strange spot, we can plan one of our custom sunrooms around it instead of forcing a standard layout.
Building a three season sunroom in Twentynine Palms
In Twentynine Palms, the city's Building and Safety Division issues permits for every structure built or rebuilt, so expect your room to need one, and applications go through the city's online portal. We prepare the plans, file them and handle the inspections, so you aren't stuck sorting out the paperwork yourself. Any contractor who requests permits or submits plans in the city also needs a City of Twentynine Palms business license, which makes it a fair question to ask whoever you're thinking of hiring.
Most rooms we build here go onto an existing slab or patio behind the house, and a good share of the work is in how the room meets the wall and the roofline. We're based in Twentynine Palms and see the same kinds of patios on jobs in Joshua Tree and Yucca Valley, along with other cities around them.

We file plans and permits
Once you say go, we prepare the plans and file them with the city. The city lists a plan review period of 15 working days for plans like these, so build that wait into your timeline.

Our crew builds the room, and I check in while it goes up. When it's finished, I walk through it with you before we call the job done.
Why Twentynine Palms homeowners call us for three season rooms
The owner writes your estimate
I'm the one who comes out, measures and writes the estimate, and I check in while our crew builds the room. The person who heard what you wanted is the one keeping an eye on how it turns out.
Building sunrooms since 2020
I learned this trade working beside an experienced sunroom installer and started this business in 2020. I like jobs with a puzzle in them, so an odd roofline or an old patio is something I want to look at, not a reason to walk away.
Fully licensed and insured
We're fully licensed and insured. That matters because California requires a state contractor license for anyone who builds or alters a structure once the labor and materials reach $1,000 or more.
Big decisions settled on paper
Screens or glass, where the room sits, and what the price leaves out all go in writing before we build anything. Those are the choices that cost the most to change once the frame is up, so I'd rather ask one more question at your kitchen table than guess.
Call (760) 362-8204 or tell us about your patio, and I'll come out to measure and talk it through.

Questions about three season sunrooms in Twentynine Palms
How much does a three season sunroom cost in Twentynine Palms?
A three season room built onto an existing base in San Bernardino usually costs about $100 to $140 per square foot with labor included, so the size of your patio moves the total more than anything. That figure leaves out insulation, extending heating or cooling, plumbing and pulling permits, so budget for those separately if your job needs them. Our estimate spells out which of those your room includes.
What is the best way to choose between a three season and a four season sunroom?
Start by deciding whether you want a room that's heated and cooled. A four season room is fully closed in with all-weather windows and its own heating and cooling, while a three season room uses screens or uninsulated glass and isn't heated or cooled. If you want a sheltered space you use when the weather suits you, the three season room is the simpler build.
How do I choose which side of the house a sunroom should face?
Pick the side by how much sun and heat you want, because south-facing windows let in the most sun in winter and less direct sun in summer, while east and west windows bring in extra heat and glare. North-facing windows give natural light with little glare and less summer heat. If you're thinking about a glass roof, Australian government guidance says roof glass takes in more heat than an unshaded west window of the same size and suggests outside blinds or louvres, which are slatted shades, over it.
How much can a contractor ask for up front on a sunroom in California?
California's Contractors State License Board caps a home improvement down payment at $1,000 or 10 percent of the contract price, whichever is less. After that, the contract lists each later payment, and each one matches work already done or materials already delivered, so you pay as the room goes up.
Is a three season sunroom considered living space?
No, the sunroom industry's own specification classes a glass- or plastic-walled room that isn't heated or cooled as non-habitable. It still holds that room to structural requirements, so it's fair to ask any contractor whether the room they're offering meets that specification.
Do I need to call 811 before a sunroom is built?
Only when the job involves digging, and then Underground Service Alert of Southern California asks for notice at digalert.org or by dialing 811 at least two days before work starts. Whether your room needs any digging depends on the base it sits on, which I check at the estimate.
