Homes and backyards across Ontario
Ontario sits just north of Chino, so it's some of the closest work we do, and the houses here aren't all one kind. In the older parts of town you see single-story homes with a patio cover somebody added decades back. In the newer tracts it's tighter yards with a concrete patio the builder poured. We see the same mix in Pomona to the west and in Upland to the north.
That mix shapes the job more than anything else. An old cover usually wasn't framed to carry walls and glass, and a builder's patio is often thinner than a room needs or slopes back toward the house, so I look at what's under the room before we talk about what goes on top.
Our services in Ontario, CA
A lot of Ontario backyards already have a slab and a cover, so closing that in is a common call here. I check whether the slab is thick and level enough to carry walls and glass before we price it, because a room that settles pulls its windows out of square.
If you want a place to sit out back without running heating and cooling into it, a three season sunroom gives you glass walls and a solid roof for less than a full addition. We tie the roof into the house cleanly so the water runs off away from your wall, not into it.
Many older houses here have a wood patio cover that's tired or was never framed to hold much. We replace it with a new cover on proper posts and footings, and if you think you'll close it in later, we build it now so it can take walls.
Rooms added to older Ontario homes sometimes leak where they meet the house or have glass and frames well past their best. We find where the water's getting in first, then replace the panels, roofing or flashing, the metal that turns water at that joint, as the room needs.
When you want a room you'll use like any other room in the house, a four season sunroom with insulated glass and a tied-in roof is the way to go. It needs a real foundation and usually electrical, so I'll tell you straight if your existing slab can't carry it.
A small builder patio in the newer tracts is often fine for a screen room even when it can't carry glass. You get the bugs kept out and the breeze let in with a lot less structure, and we can frame it so it can be glassed in down the road.

What happens when you call us about a sunroom in Ontario
Call us or send the form
I come out myself to see the space, measure it and ask how you plan to use the room. It helps if you're home so we can stand out back and talk it through.
Get your written estimate
You get a written estimate that spells out what we'd build and what it sits on, your existing slab or new footings. You see the whole picture before you sign anything.
We handle the city side
Once you sign, we take care of the city's paperwork, and the city checks the plans before we build and inspects the work along the way. I keep you posted as it moves.
Build it, then walk it
My lead installer runs our own crew on site, from the base through the roof tie-in. When it's done, I walk the finished room with you and show you where the water goes.
Ontario sunroom questions answered
How do I find out if my sunroom needs a permit in Ontario, CA?
Ask the city's Building Department, which issues permits for buildings and projects in Ontario and can be reached at (909) 395-2023. When you hire us, we check with it about your address before anything is built and take care of whatever it asks for.
Do I need a licensed contractor to build a sunroom in Ontario?
Yes, in almost every case. California requires a license from the Contractors State License Board for anyone contracting on work that needs a building permit, uses employee labor or comes to $1,000 or more in labor and materials combined. The only way around it is a job with no permit, no employees and under $1,000 in total, and a bigger job can't be split into smaller contracts to get under that line. We're fully licensed and insured.
Does a contractor from outside Ontario need a city business license?
Yes. The City of Ontario requires a business license before a business starts work in the city, and contractors based outside the city limits use the same application as local ones. Out-of-city contractors give the job location and value, along with their state license number and workers' comp details.
How much does a sunroom cost in Ontario?
It comes down to what the room sits on, how big it is and how closed in you want it, so your real number comes from a look at your yard. A room that can go on your existing slab costs less than one that needs new footings, and a screen or three season room costs less than a four season room with insulated glass and electrical. How the roof ties into your house moves it too, and your written estimate spells all of it out.
How long does it take to get a sunroom built in Ontario?
It depends mostly on the city's plan review and inspections, what the room sits on and when materials come in, so I'll give you a realistic picture once I've seen the site. If a plan check or permit needs more time, the city's first extension is free and each further one it grants costs $150 on a home, which is one reason we keep the paperwork moving.
How much can a contractor ask for as a down payment on a sunroom in California?
The board's guidance says a contractor can't ask for or take a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. After that, payments are listed in the contract and tied to work done or materials delivered, and those rules cover all home improvement projects.
