About Ontario, CA

Ontario is a short drive from where we're based in Jurupa Valley, and we work here much as we do in Chino and Rancho Cucamonga. It's a big, busy city with freeways, warehouses and shopping on one side and street after street of homes on the other. The backyards we see run from older single-story houses with a patio slab and a worn cover to newer tract homes on tighter lots.

That spread is what shapes the job. On older houses it's mostly about whether the slab, deck or cover out back can carry a room, and on newer ones it's fitting the room to a smaller yard and a roofline nobody drew with an addition in mind.

Services in Ontario, CA

  • Patio enclosures

    Many Ontario homes already have a covered patio off the family room, and patio enclosures close it in with windows, screens or both, so you get a room without starting from bare ground. We match the frame to the house so it doesn't look tacked on.

  • Patio-to-sunroom conversion

    When there's already a cover over the slab, a patio-to-sunroom conversion keeps what's worth keeping and adds walls, windows and a door. This is the kind of job we're known for, because getting a real room out of a patio that was never built for one takes some figuring.

  • Deck-to-sunroom conversion

    Some older Ontario homes have a raised wood deck off the back that has seen better days. We look at the footings and framing before anything else, since a room on top puts far more weight on them than a few chairs ever did.

  • Patio cover installation

    Plenty of yards here have a bare slab with nothing over it. We build covers that tie cleanly into your roof, and if you think you'll close it in someday, we size the posts and roof for walls now so you aren't paying twice.

  • Four season sunrooms

    Families here often want the extra space to work as a den, an office or a playroom every month of the year. A four season room is insulated and finished like the rest of the house, and we match it to your roof and siding so it looks like it was always there.

  • Sunroom remodeling

    Older houses in Ontario sometimes come with a sunroom or enclosed patio a previous owner put up, with leaky panels or a floor that has dropped. We figure out what can stay and what has to go, so you're not paying to replace parts that are still sound.

What a sunroom job in Ontario involves before we build

In Ontario, permits go through the city's Building Department, which checks the plans before work starts and inspects the work as it goes up, and whether your room needs a permit is the department's call. Those reviews set part of the schedule, so I reach out to them early and you'll know what to expect before we start. You can check any contractor's state license before you hire them, and the city requires a business license from contractors who work here, including ones based outside Ontario like us. We're licensed and fully insured.

We take care of any permits your project needs and the paperwork with the city, the same way we do in Corona and the other cities around Jurupa Valley. What moves your price most is what's already in your yard, because a sound slab or cover we can build on costs less than one we have to repair or replace. After that it's the room itself, a screened room versus a four season room with insulated walls and glass, plus its size, how the new roof ties into yours and whether you want lights, fans or outlets, and your written estimate lays those options side by side.

Ontario, CA properties and local conditions

The patio slab is the first thing I look at on most Ontario jobs. A lot of them were poured as a patio, not as the floor of a room, so they can be thin at the edges, cracked or sloped away from the house, which is fine for rain but not for walls and a door that has to close right. We check the edges and the condition of the concrete, and depending on what we find we add footings, level the floor inside or pour new where the old slab can't be saved.

The other thing we run into is the cover already over the patio. Many were built for shade, with light posts and lattice, and weren't meant to hold windows, a solid roof or walls hanging off them, so we either reinforce them or replace them with a roof built for a room.

How it works when you call us about a sunroom in Ontario

  1. Call us or send a request

    Tell us a little about the patio, deck or room you have in mind, and we'll set up a time to come out to your Ontario home. It helps if you're there, since most of the visit is me asking how you want to use the space.

  2. I come out and measure

    I measure, look over the slab, deck or cover you have now and talk through how you'll use the room. Then you get a written estimate with your options laid out, so you can see what each choice does to the price before you decide anything.

  3. We handle the permit paperwork

    Once you say yes, we take care of the permit paperwork with the city. The city reviews the plans before work starts and inspects as the room goes up, so those reviews set part of the schedule.

  4. Build and a final walkthrough

    Our installers do the build, starting with whatever the base needs before any walls go up. When it's done, I walk the finished room with you so you can check every window, door and detail.

Frequently asked questions

Do I need a licensed contractor to build a sunroom in Ontario, CA?

Almost always, yes. California requires a current license from the Contractors State License Board for anyone contracting on work that needs a building permit, uses employees, or comes to $1,000 or more in labor and materials together, and a sunroom usually hits at least one of those. The board's small-job exemption only applies when there's no permit, no employee labor and the total stays under $1,000, and a bigger job can't be split into smaller contracts to get under it.

How much can a sunroom contractor in Ontario ask for up front?

California caps the down payment on a home improvement job at $1,000 or 10 percent of the total contract price, whichever is less. The rest of the payments are listed in the contract and based on work completed or materials delivered, so look for that schedule before you sign.

Is it cheaper to enclose my patio cover than build a new sunroom in Ontario?

Often it is, if the slab and the cover are sound enough to carry walls, windows and a real roof, because you're not paying to pour and frame what's already there. When the cover is light lattice or the slab is cracked or sloped, the savings shrink, and sometimes starting fresh costs about the same and gives you a better room. I'll put both options in your estimate so you can compare them.

Does Ontario charge a fee to extend a building permit?

Yes, but not for the first request. The city doesn't charge for the first extension on a plan check or permit, and each further extension it grants costs $150 on a residential permit. Keeping the job moving once the permit is issued avoids that, which is one reason we stay on top of the paperwork from the start.

How long does it take to build a sunroom in Ontario?

Most of the calendar is set by the steps around the build, like the estimate visit, the city's review of the plans and the inspections along the way, more than by our installers' time on site. Repairs to a cracked slab or a worn deck add time too, which is why I'd rather find them at the estimate than once the walls are going up.

What is the best way to add a sunroom to a small backyard in Ontario?

Start with how you want to use the room and size it to that, because on a tighter lot a few feet can be the difference between a room that works and a yard you've given up. I measure the space, look at where your roofline lets a new roof tie in, and sketch a couple of sizes so you can see what you gain and what you keep.
