Sunroom Contractor in Fontana, CA - Turning Covered Patios Into Real Rooms
Rancho Cucamonga Sunrooms & Patios is a sunroom contractor building sunrooms, patio enclosures and patio covers for homes in Fontana. I measure the job myself, and our own crew builds rooms that keep water out and doors closing right.
Fontana: covered patios waiting to become rooms
In Fontana we mostly work on single-family houses with a covered patio out back, from older homes in the older parts of the city to newer tract streets. Most calls here sound like the ones we get next door in Rialto. The family already uses that patio every day and wants it to work like a real room.
Some of those patios are ready to build on. Others have a cover that went up fast and has been leaking at the house for years, so the same request can mean a straight enclosure on one street and a new cover first on the next.

Sunrooms and patio rooms we build in Fontana
Patio enclosures
Plenty of Fontana houses already have a covered patio out back, so closing it in is often the shortest way to a usable room. A patio enclosure only makes sense when the cover and slab are sound, and I'll tell you on site if yours aren't.
Patio-to-sunroom conversion
When you want that patio to feel like part of the house, with glass, a solid roof and a door that seals, we convert it into a sunroom. We tie the new roof into your house so rain runs off it instead of into the wall.
Patio cover installation
A lot of the older aluminum and wood covers we see here sag or leak where they meet the house. We replace them with a cover that's attached and sealed properly at the wall, which also gives you a good start if you want to close it in later.
Sunroom remodeling
Some Fontana calls come from people living with a room somebody built in a hurry, with sticking doors, fogged glass or stains on the ceiling. We open up the problem and fix what's causing it instead of hiding it behind new trim.
Sunroom additions
On lots with room beside or behind the house, a new sunroom on its own foundation can make more sense than reusing a tired old slab. We build it as part of the house, so the roof, doors and windows work the way the rest of your home does.
Screen room installation
If you want the patio for evenings without the bugs and don't need it closed up all year, a screen room costs less and keeps the air moving. We build it on the same kind of solid frame we'd use for glass, so you can upgrade later without starting over.
What we know about building in Fontana
If your house is inside Fontana's city limits, the permit goes through the city's Building & Safety office, and if it's in the unincorporated part of Fontana, the County handles it, so the first thing we check is which side of that line your address sits on. When a job needs a permit, we pull it and work with the building office through the inspections, and we don't start building until it's issued, so the city's review sets the start date more than anything we do. Every business working in the city needs a Fontana business license, so ask to see one from any contractor you're considering.
The price moves with the size of the room, glass walls or screens, the roof, and whether your slab and patio cover are good enough to build on, and the schedule moves with the permit review and how much old work has to come out first. I come out myself, look at what's there, measure and put the price in writing. We're based next door in Rancho Cucamonga, and our own crew does the same work in Jurupa Valley and the other cities around Fontana, with me on the job alongside them.

Sunroom questions from Fontana homeowners
Who can sign for a building permit in Fontana?
Once the fees are paid, only the contractor signing for the job or the property owner can sign for a Fontana building permit. Anyone else needs written permission notarized by one of them. The city's permits page also says an owner who pulls a permit for a contractor's work takes on the liability for the project, including taxes and personal injury, which is one reason we pull the permit ourselves when a job needs one.
Does a contractor based outside Fontana need a city business license to build my sunroom?
Yes, Fontana requires every business working in the city to hold a city business license, even one based somewhere else. It costs a $35 application fee, then $15 to renew each year, plus a yearly business tax based on the business's estimated gross receipts. A license runs one year from the day it's issued, so check that the one you're shown is current.
Can I apply for a building permit online in Fontana?
The city's building office encourages applicants to set up an account on the Build Fontana Public Portal, and it also takes permit applications in person at its counter at 8353 Sierra Avenue. The counter is open Monday through Thursday and closed every Friday. When your job needs a permit, we handle the application, so you won't have to.
How much does a sunroom cost in Fontana?
It depends on your job, mostly the room's size, glass or screen walls, the roof, and whether your existing slab and patio cover are sound enough to build on. Tearing out a leaking cover or a cracked slab adds to the price, while reusing a good one keeps it down. When a job needs a permit, the city's fees come on top, and paying them through the city's online system adds a service fee of a flat $3.00 by bank transfer, or a percentage plus $0.20 by card.
How do I turn my covered patio into a sunroom in Fontana?
Start by having the slab and the cover checked, because a cover that already leaks at the house will leak worse once it's closed in. I look at how the cover ties into your wall and where the roof water goes, then we decide together whether to enclose what's there or rebuild part of it. If you bought the house recently, the city asks for proof of ownership with the permit application, so keep your closing papers handy.
What causes an old patio enclosure to leak in Fontana?
Usually it's the joint where the cover meets the house, because the flashing, the metal strip that sheds water off that joint, was skipped or done wrong. The other common causes are a roof with too little slope and gutters that dump water back against the wall. I spent years fixing these, and we fix the path the water takes instead of covering the stain with new trim.
