About Ontario, CA

Ontario sits on the west side of the cities we cover, past Fontana and next door to Rancho Cucamonga, and it's a big city with a busy commercial side. The calls we get here come from the residential streets, where you'll find a mix of older houses and newer tracts. Most come from homeowners with a slab out back that only gets used a few times a year, a patio cover that's seen better days, or a sunroom an earlier owner added that never quite worked.

What's already behind the house decides most of the job here, because a solid slab and a sound wall where the room ties in let us build on what you have, and a tired slab or cover means we start a step earlier.

Services in Ontario, CA

  • Patio-to-sunroom conversion

    A lot of Ontario backyards already have a concrete patio against the house, and that slab can often become the floor of a room if it's level and solid enough. I check it first, and then we either build walls, glass and a roof on what's there or fix the slab before we start.

  • Patio enclosures

    If you like the patio cover you have and just want more use out of the space, we can close in the sides with windows, screens or panels. That's usually less work than a new room, as long as the cover's posts and beam are sound enough to carry the new walls.

  • Sunroom remodeling

    We see a fair number of rooms here that an earlier owner added, which leak where they meet the house or just never get used. Our sunroom remodeling work replaces the roof, panels or windows that aren't working and keeps the frame when it's still good.

  • Patio cover installation

    Plenty of houses here have an older cover over the patio that's sagging or too small for how the yard gets used. We build new covers sized to the space and tied into the house so water runs away from the wall, and we can plan them so they're easy to close in later.

  • Screen room installation

    If you want to sit out back in the evening without the bugs, a screen room keeps the air moving and costs less than a glass room. We build it on your slab or deck under a solid roof, so you can add windows later if you decide you want a full room.

  • Four season sunrooms

    When a family wants a room they'll use every day, as an office, a playroom or a place for the TV, we build a four season room with insulated walls, roof and windows. It ties into the house like any addition, so it takes the most planning up front.

Working in Ontario: permits, licenses and what sets the price

When your room needs a permit, it comes from the City of Ontario's Building Department, which reviews the plans before work starts and inspects the work as it's built, so the schedule runs on that review as much as on our crew. Before you hire anyone for the job, check two things, a current California contractor's license and a City of Ontario business license, which the city requires from contractors based outside its limits as well as inside.

We're based in Colton and work in cities all around it, from Grand Terrace out to Ontario, and when your project needs a permit we confirm which building office covers your address, prepare the plans, handle the paperwork and set up the inspections. The price mostly turns on the size of the room, whether it's screened or fully closed in and insulated, the glass and roof you choose, and whether your slab or deck can carry it as it is, and I'll put your own figure on all of that in a written estimate.

Ontario, CA properties and local conditions

Many of the older patio covers we see in Ontario were hung off the house at the roof edge in a way that works for shade but not for a room. A room needs a roof that ties into the house so water runs off instead of in at the wall, so I look closely at that connection and the roofline before we talk about glass or layouts. If the old cover has to come down, we tell you at the estimate, not halfway through the job.

Where a second story sits over the back patio, the room's roof has to tuck under the upstairs windows, and that sets how tall the room can be and which way it drains. We plan the pitch and height around those windows first.

Get a free on-site sunroom estimate in Ontario

Send the form and we'll reply within one business day to set up a time for me to come out to your house in Ontario. The estimate is free, with no pressure and no obligation, and you'll get it in writing after I've seen the patio or room and we've talked about how you'll use it.

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

  1. Call or send a message

    Call (909) 679-6010 or use the form, and we'll set up a time for me to come out. It helps if you're home for the visit, since a good part of it is talking about how you'll use the room.

  2. Walk the space with me

    I look at the patio, deck or slab and at where the room will meet the house, and ask how you plan to use it. Then you get a written estimate that spells out what you're paying for, and I'm glad to go over any line of it twice.

  3. We handle plans and permits

    Once you're ready, we prepare the plans and file the permit paperwork with the city, which reviews them before building starts. If a review needs more time, the city doesn't charge for the first extension request, and each further one it grants costs $150 on a residential permit.

  4. Build, then walk through together

    Our crew builds the room, with the city's inspections set up along the way when the job has a permit. When it's done, I walk through the finished room with you.

Frequently asked questions

How do I know if I need a licensed contractor for a sunroom in Ontario, CA?

In California you need a licensed contractor for any job that needs a building permit, uses hired workers, or comes to $1,000 or more in labor and materials combined, and few sunroom projects come in under that. The state licensing board only allows an exemption when a job needs no permit, uses no employees and totals less than $1,000 across every contract, and a bigger job can't be split into small ones to get under that line. We're licensed and insured.

How much of a down payment can a sunroom contractor ask for in California?

Under the state licensing board's guidance, a down payment can be no more than $1,000 or 10 percent of the total contract price, whichever is less. Payments after that should be listed in the contract and tied to work done or materials delivered, and the rule covers all home improvement work, so a request for a big check up front is a reason to stop and ask questions.

How much does a sunroom cost in Ontario, CA?

Your price comes from a written estimate after I've seen your place, because the same size room costs different amounts depending on what it's built on and how it's closed in. A screen room over a sound slab sits at the lower end, an insulated room with glass, a solid roof and electrical work sits higher, and a slab that needs replacing or an old cover that has to come down adds to either one.

What is the phone number for the City of Ontario Building Department?

The Building Department's phone number is (909) 395-2023. Its Building Counter closes for staff meetings every Tuesday from 7:30 to 9:00 am and the first Thursday of every month from 8:00 to 10:00 am, so plan around those times if you go in person.

What is the best way to choose between a screen room and a four season sunroom in Ontario?

Choose by how you'll use the room, not by what's biggest. If you picture a couch, a desk or a TV in there, go with a four season room, and if it's for dinners outside with outdoor furniture, a screen room or three season room does the job and costs less. I'll ask about this at the estimate, and I'd rather spend the extra time on it than have you wish you'd picked the other one.

How do I tell if my old sunroom in Ontario should be remodeled or replaced?

If the frame is straight and solidly attached to the house, a remodel is usually the better buy, because the roof, panels and windows are what wear out first. If the frame is rotted, pulling away from the wall, or sitting on a slab that's cracked and sinking, replacing it is usually the better call, and I'll show you what I'm seeing so you can judge it too.
