What goes into a sunroom addition in Rialto?
A sunroom addition in Rialto is a new room built onto your house on an existing base, usually a slab or a sturdy deck, with its own windows, walls, roof, fixtures and power, so space you barely use out back becomes part of your home.
Most of the calls I get start the same way. There's a slab or a deck out back that nobody uses, and you want a real room there instead, so a lot of our work is patio-to-sunroom conversion. The price moves with the size of the room, whether it needs a new foundation, whether you want it heated and cooled, and how much insulation and glass go in. The schedule mostly turns on how fast we settle the design and how long the city takes to review the plans. Once I've seen your house, you get a written quote with your own numbers in it.
How do you know your house is ready for a sunroom?
A patio nobody sits on
You walk past it every day and only use it a few weekends a year. That usually means the space is fine but has no walls, glass or comfort, and every year you wait is another year that square footage you already own goes unused.
Rooms feel crowded inside
There's a desk in the kitchen, toys in the hallway and guests sleeping on the couch. That usually means you've run out of rooms, and building on a base you already have is often a simpler fix than pushing out a wall of the house.
A deck that's starting to give
You feel a bounce when you walk across it, or you see soft boards and tired posts. That usually means the deck needs work before anything sits on it, and putting it off only lets the damage spread further.

How we build a sunroom addition
If you want the room on top of an old deck, I look hard at what's holding it up before anything else gets planned, because a room is only as good as what's under it, and on a slab I check that it's sound and level. Then we lay the room types out side by side so you can match one to how you'll really use the space. Once you pick, our crew frames the walls, sets the windows, puts on the roof and siding, runs the electrical and finishes the inside. We spend the most care on the flashing, the metal that seals the spot where the new roof meets your house, because that's where a room either stays dry or doesn't.
If you already know you want heat and air so the room works every month, our four season sunrooms page goes into that build. If you mostly want a bright spot for the milder months and less to pay up front, look at our three season sunrooms.
Four season room
This suits you if you want a room you use all year. It's heated and cooled with all-weather windows and insulation, so it works like the rest of your house, and it costs the most of the three.
Three season room
This suits a reading spot or a place for dinner in good weather. It usually isn't heated or cooled and has uninsulated windows or screens, which keeps the cost down.
Screened room
This suits you if you mostly want shade and fresh air without the bugs. It has screens only and no windows, so it's the simplest build of the three.

The owner measures, then builds
I come out myself to look at the house and measure, and our own crew does the building with me on site. You're talking to the person who actually saw your slab, not someone reading it off a work order.
A straight no when needed
If a slab or an idea isn't going to work, I'll tell you up front. I'd rather lose the job than build you a room you regret.
Licensed and fully insured, every build
We're licensed and fully insured. Ask anyone you hire how they're licensed, because California's awning contractor license covers patio covers but not patio enclosures.
Rialto fire and zoning rules planned in
If your house is in a High or Very High Fire Hazard Severity Zone, Rialto's Fire Department says new construction and renovations have to meet the Wildland-Urban Interface building codes and the city's home hardening requirements. We check that and the city's zoning before we draw anything, so the room you approve is one the city will let us build.
The room has to sit on a base that can carry it and stay dry once it's built. Tell us about your patio or deck and I'll come take a look.
What happens after you call about a sunroom addition?
Call or send the form
Tell us what's out back now and what you'd like the room for. We'll set a time for me to come out.
I measure and look underneath
I measure, check the slab or deck and how your house is built, and we talk through how you'll use the room. You get a written quote that spells out what's included, so you can compare it line for line.
We file for the permit
Once you approve the quote, we put in the permit application and handle the inspections. Rialto's online permit status lists a review time of 30 days for plans in review with city departments, so plan your start date around that.
Our crew builds, start to inspection
Our crew frames, glazes, roofs and finishes the room, with me on the job through the final inspection. We clean up as we go so your yard is usable when we pack up.
Common questions
How much does a sunroom addition cost near Rialto?
A sunroom in the San Bernardino area usually costs about $95 to $195 per square foot. One San Bernardino estimate leaves out insulation, heating or cooling, plumbing and permits, so check what every quote includes, ours too. Our written quote lists what's in it so you're not guessing.
How do I decide whether to insulate my sunroom now or later?
Decide now, while the room is still on paper. Insulated windows and insulation in the walls, floor and roof are much easier to put in during the build, and adding them later can often cost more. California's Energy Code also applies to substantial additions to existing homes, so we plan for it in the first drawing.
Can a sunroom be built on my existing deck?
Sometimes, if the deck is strong enough to carry it. One maker's guide notes many decks aren't designed for the added load and says a local engineer or qualified contractor should review the deck first. If yours won't hold a room, I'll say so and we'll talk about a deck-to-sunroom conversion that starts with a stronger base.
Who handles permits for a sunroom addition in Rialto?
The City of Rialto's Building Department handles plan check, permits and inspections for building permits inside the city. When your addition needs a permit, we put in the application and deal with the inspections for you.
What is the best type of glass for a sunroom?
For most rooms, upright glass walls are the better pick over sloped glass overhead. Upright glass costs less and is easier to install and insulate, and it's less prone to leaking, fogging and breakage. That's what I steer people toward when they want a room that stays dry.
How do I take care of a sunroom once it's built?
Look over the roof and gutters once a year. One maker's guide suggests an annual inspection of the sunroom roof and gutters, and clearing out leaves while you're up there is ordinary upkeep that keeps water moving off the room.
