Rancho Cucamonga homes and their back patios
Rancho Cucamonga grew out of three older towns, Alta Loma, Etiwanda and Cucamonga, and each one's old center still has its own feel. Most of the houses came later. The area grew fast in the 1970s, when families from Los Angeles and Orange County came looking for homes they could afford, and building has kept going since, much like it has next door in Fontana. So one week we might be behind a house from that first big wave, and the next behind a much newer one.
For a sunroom, that usually means we start from something already there, like a slab patio, an older cover or a room somebody added years ago. Before we draw anything, I check whether that slab and the wall it meets can carry a real room, because a room is only as good as what it sits on.

Sunroom work we do in Rancho Cucamonga
Patio-to-sunroom conversion
Plenty of houses here have a slab patio out back that only gets used a few times a year, and closing it in is the kind of call we get most. We check the slab and how it meets the house before planning any walls on it, so the new room doesn't settle or pull away later.
Patio cover installation
A lot of the older covers here are faded aluminum that sags or leaks where it meets the house. We put up a cover sized and attached for your house, and if you might close it in someday, tell us now so we can plan the cover with that in mind.
Sunroom remodeling
Some of the add-on rooms here were built decades ago and now have foggy glass, sticky sliders or a roof that drips. Our sunroom remodeling keeps what's still sound and replaces what isn't, so you're not paying to tear out a frame that's fine.
Four season sunrooms
If you want the room to feel like part of the house all year, a four season room is built with insulated walls, roof and glass instead of a light frame. I'll tell you straight whether your house and budget suit one, because sometimes a three season room is the better fit.
Screen room installation
Not everyone wants glass, and if you mostly want shade and fewer bugs on the back patio, a screen room does that for less. We build it on your slab or under your cover, and we can often set it up so glass could go in later.
Sunroom design
Houses here run from the first big wave of tract homes to much newer neighborhoods, and a room that suits one roofline looks bolted on next to another. We sit down with you, go through each choice and draw the room to match your house before anything gets built.
Working in Rancho Cucamonga: permits, licenses and price
Permits here go through the City of Rancho Cucamonga, so before we start we confirm what the city needs for your job, and when it calls for a permit, we take care of the paperwork with them. Work waits until the permit is issued, so that review usually sets the start date. Before you hire anyone, ask for two things. One is a state contractor license from the Contractors State License Board. The other is a city business license, which anyone doing business in Rancho Cucamonga needs before they start. We're licensed and fully insured.
Rancho Cucamonga is an easy run up from Bloomington, and we do the same work in Ontario just south of it. What moves your price is the size of the room, whether it's screen, glass or fully insulated, how much of your slab and cover we can keep, and whether you want power, lights or a fan run out to it. The schedule mostly turns on settling the design, the city's permit review and how long the made-to-size parts take, and I'll go through all of it with you when I come out to look.

Sunroom questions from Rancho Cucamonga
Do I need a permit for a patio cover or sunroom in Rancho Cucamonga?
For a patio cover, yes, the City of Rancho Cucamonga issues permits for patio covers along with solar and reroofs. A full sunroom isn't named on that list, so ask the city's Building and Safety office about your plans, and note that permits there are applied for online. When your job calls for one, we handle the paperwork with the city.
Does a contractor need a business license to work in Rancho Cucamonga?
Yes, anyone doing business in Rancho Cucamonga has to get a city business license before they start, and it's renewed every year. It's separate from the state contractor license, so it's fair to ask whoever you hire about both.
How much can a contractor ask for as a down payment on a sunroom in California?
Under state contractor rules, a down payment can't be more than $1,000 or 10 percent of the contract price, whichever is less. Every payment after that has to be listed in the contract and tied to work done or materials delivered. If someone wants a big check before anything shows up at your house, I'd walk away.
How much does a sunroom cost in Rancho Cucamonga?
Your price comes down to the size of the room, how it's built and how much of what's already there we can reuse. A screen room on a sound slab costs far less than an insulated four season room that needs new footings and a roof tied into the house, and power, lights or a ceiling fan add to it. I'll look at your patio and give you a number for your house, not a guess from a chart.
How long does it take to turn a patio into a sunroom in Rancho Cucamonga?
Most of the wait usually comes before building starts, while we settle the design, the city reviews any permit the job needs and the made-to-size parts get ordered. The build itself depends on the room's size and whether we're reusing your slab, and I'll give you a realistic schedule once I've seen your house.
What is the best way to turn an old patio cover into a sunroom?
Usually the best way is to check the cover and slab first and replace whatever can't carry a real room, rather than hanging walls and glass on a cover built for shade. Many older aluminum covers weren't made to hold that kind of weight, so we often keep the slab and build a new roof. If both turn out sound, I'll tell you, because there's no sense paying to replace good work.
