Homes and backyards across Rancho Cucamonga
Rancho Cucamonga grew out of three older towns, Alta Loma, Etiwanda and Cucamonga, and each part of the city still has its own feel. A lot of it filled in fast starting in the 1970s, when families from Los Angeles and Orange County came out looking for houses they could afford, so on our jobs here we see houses from several decades, from older places with long patios to newer tracts with tighter yards.
Most calls we get here sound a lot like the ones from Fontana next door, a homeowner with a covered patio who wants it to be a real room. What decides the job is the slab under it and how the house is framed where the new roof meets the old one, so that's what I look at first.
What to know before you build in Rancho Cucamonga
Permits here come from the City of Rancho Cucamonga. The city's permit list names patio covers but doesn't spell out sunrooms, so whether your room needs one is the city's call, and we check with them about your job before we build. Before you hire anyone, look up their state contractor license with the Contractors State License Board, and know that the city also wants its own business license from anyone working here.
We're licensed and fully insured, and when a job needs a permit we handle the application and the inspections, so the paperwork isn't on you. The price moves with the size of the room, whether it's screened, glassed or fully insulated, the shape your slab is in and how the roof ties into the house, and the schedule turns mostly on permit review and any slab work we find. It's the same work we do in Upland and over in Riverside, and the written quote after the estimate gives you your own number.

Patio enclosures
A lot of Rancho Cucamonga backyards already have a covered slab that only gets used a few weeks a year. Our patio enclosures close in that space with walls and windows so it works as a room, after we check that the slab and cover can carry it.
Patio-to-sunroom conversion
When the patio is the size you want and the slab is sound, we turn it into a finished room with walls, windows and a roof tied into the house. It's the job we're best known for, and it gets you real living space without starting from bare dirt.
Patio cover installation
Some yards here have no cover at all, or one that's tired and sagging. We put up a new cover framed to tie into your roofline, so it can be closed in later if you decide you want a room.
Four season sunrooms
If you want a room you'll use every month, a four season room is built with insulated walls, roof and glass like the rest of the house. It costs more than a screen room, and it's the one I'd pick if a desk or a couch is going out there.
Screen room installation
For homeowners who mostly want shade and to keep bugs off the table, a screen room is the simpler build. We frame it right on your existing slab when it's level and solid.
Sunroom remodeling
With houses built across several decades here, we run into older sunrooms and enclosures that leak at the roof or just feel worn out. We find where the water gets in, fix it, and update the glass and finish so the room is worth sitting in again.
What happens after you call us about a Rancho Cucamonga sunroom
Call or send the form
Call (909) 546-5002 or send the form with a line about the patio or room you have in mind, and we'll set a time to come out. It helps if you're home for the visit so we can talk it through together.
I measure and look it over
I come out myself, measure, and check the slab or deck and how the house is built where the room will attach. We talk about what you'll use the room for, because that decides screen, glass or fully insulated, and that's most of the price.
You get a written quote
You get the quote in writing with what's included, so there's nothing to guess at. If the job needs a permit, we file it with the city and wait on their review before we start.
We build it and finish up
Our own crew does the building with me on site, and I stay on the job through the final inspection. We clean up before we call it done.
Common questions
Does a patio cover in Rancho Cucamonga need a city permit?
Yes, patio covers are on the list of work the city issues permits for. You apply online through the Online Permit Center on the city's Building & Safety page, and the permit is issued by email. When we're building your cover, filing it is part of our job.
Does a contractor need a city business license to work in Rancho Cucamonga?
Yes, the city requires a business license from everyone doing business inside the city, and it has to be in place before work starts. It's renewed every year and is separate from the state contractor license, so a builder working here needs both, and one based outside the city also lists the job's location and value when applying.
How much of a down payment can a sunroom contractor ask for in California?
Under state contractor rules, a down payment can be no more than $1,000 or 10 percent of the contract price, whichever is less. After that, each payment should be written into the contract and tied to work done or materials delivered, and the rule covers home improvement jobs like a sunroom.
How much does a sunroom cost in Rancho Cucamonga?
Your price comes from the size of the room, how it's built and what your slab and house let us do, which is why I give a number only after I've seen it. A screen room on a sound slab sits at the low end, and an insulated room with full glass and a new roof tied into the house costs the most. A cracked or uneven slab adds work, and I'll show you where before it goes into the quote.
What is the best way to turn a covered patio into a sunroom in Rancho Cucamonga?
Start with what you want the room for, because that decides whether a screen room, a glass room or a fully insulated room makes sense. Then the existing cover needs a hard look, since an older cover often can't carry walls and glass and has to be replaced with a roof framed for the job.
How do I know if my existing patio slab can hold a sunroom?
Usually it can if the slab is solid, level and big enough for the room you want, and I check all three at the estimate. With houses here built over several decades, we see slabs in every kind of shape, and some need repair or replacing first. If yours won't work, I'll tell you up front rather than build on it and have you regret it.
