Homes and backyards across Rancho Cucamonga
Rancho Cucamonga grew out of three older communities, Alta Loma, Etiwanda and Cucamonga, and a lot of it filled in fast once families came out from Los Angeles and Orange County looking for a house they could afford. We're based in Chino and work all through here, the same way we do next door in Upland and down in Ontario.
Out back, that growth left a mix. Some houses still have the slab and cover they came with, some have a cover a past owner added, and some have a deck or bare yard. What the room sits on and how its roof meets your house set most of the price, and whether that needs work first is what usually moves the schedule. That's why I look there before anything else, and it's what your written estimate spells out.
Our services in Rancho Cucamonga, CA
Plenty of Rancho Cucamonga backyards already have a slab and a cover, so a conversion is usually the first thing people ask about. We enclose the space you already use and tie the new roof into your house so water runs away from the wall, not down it.
When there's no cover yet, or the old one is tired, we build a new patio cover with posts and footings sized for the job. Build it right the first time and you can enclose it later without tearing it out.
Some folks here want to sit out in the evening without the bugs and don't need glass at all. A screen room built on the patio you have is lighter and costs less than a glassed room, and it still gives you a real place to sit.
If you want a room you'll use like the rest of the house, a four season room gets insulated walls and roof and windows you can close up tight. It's a heavier room than a screen room, so what it sits on matters even more, and I check that before anything gets sold.
A lot of older homes here have a room out back that someone added years ago, and it's starting to show it. We find out why first, whether it's a roof seam, a failed seal or a slab that's moved, and fix that before we change what you see.
When there's no slab or cover where you want the room, we build it as an addition from the ground up. That means a foundation sized for the room and a roof tied properly into your house, the two parts you stop seeing once it's done.

What happens when you call us about a Rancho Cucamonga sunroom
Call or send us the form
Call (909) 413-6398 or send the form, and we set a time for me to come out to your house. I do the estimate visit myself, and it helps if you're home for it.
I measure and look underneath
I measure the space, check the slab, deck or cover the room would sit on and ask how you plan to use it. You get a written estimate that spells out what we'd build and what it sits on, so you can see what the price pays for.
We handle the city side
Once you sign, we take care of the city side for your Rancho Cucamonga address so you aren't the one chasing it. The room goes up once anything the city asks for is done, so that step sets when we can start.
Our crew builds, then we walk it
My lead installer runs our own crew on site while the room goes up. When it's finished, I walk the room with you and we go over the roof edge, the seals and where the water goes.
Rancho Cucamonga sunroom questions
Do I need a permit for a sunroom or patio cover in Rancho Cucamonga?
Patio covers are on the list of jobs the City of Rancho Cucamonga issues permits for, along with solar and reroofs. The list doesn't name sunroom enclosures, so we check with the city's Building & Safety office about your address and take care of the paperwork it asks for. Permits there are applied for online, and we keep you posted as yours moves along.
Does a contractor need a business license to work in Rancho Cucamonga?
Yes, the city requires a city business license for everyone doing business inside the city, taken out before the work starts and renewed every year. That's separate from the state contractor license issued by the Contractors State License Board, so a contractor working here needs both, and we're fully licensed and insured.
How much can a contractor ask for up front on a sunroom in California?
A down payment on a home improvement job in California can't be more than $1,000 or 10 percent of the contract price, whichever is less. That's the state board's rule, and every other payment has to be listed in the contract and tied to work done or materials delivered.
How much does a sunroom cost in Rancho Cucamonga?
The price comes down mostly to the size of the room, what it sits on and how its roof ties into your house. A screen room on a sound slab sits at the low end, and a four season room, or any room that needs a new foundation or a replaced patio cover first, costs more. Your estimate gives you the figure for your own house, in writing.
How long does it take to add a sunroom in Rancho Cucamonga?
The schedule usually turns on two things, how long the city side takes for your address and whether your slab or cover needs work before the room can go up. A room going onto a sound slab under a cover that can carry it moves faster than one that needs a new foundation first, and I'll tell you which one you're looking at when I come out.
What is the best way to turn a covered patio into a sunroom in Rancho Cucamonga?
Start by finding out whether your slab and patio cover can carry a closed room, because that decides everything after it. Plenty of covers were built for shade, not to hold walls and glass, and a slab poured for patio furniture may need reinforcing or replacing. If they're sound, we build on them, and if they're not, I tell you straight and we fix what's underneath first.
