Sunroom additions in Rancho Cucamonga CA - a dry room with doors that close right
Patio or deck sitting unused? We add a sunroom sized to how you'll use it and priced so you can finish it.
What goes into adding a sunroom in Rancho Cucamonga?
A sunroom addition in Rancho Cucamonga encloses a space attached to your house with windows or screens, and the finished room can be anything from a screened porch to a space that works like a regular room addition.
Most people who call us have a patio or deck they hardly use because it's too hot, too buggy or too exposed, and they want a real room out of it. The price moves most with the size, whether the room is heated and cooled, how much insulation and window performance goes in, and what the room sits on, since an old deck or slab may need more support under it. The schedule usually turns on that groundwork and on the permit, and you'll know your own figure once I've measured and put the price in writing.

Sunroom additions, up close
How we build a sunroom addition
We start by going over size, room type and budget together, so the room we price is one you can afford to finish instead of one that stalls halfway. Then I look hard at what the room will sit on, because a deck usually needs added beams, posts or footings, and a slab or bare ground needs footings or a foundation that suit the room. Our crew frames the walls and roof, sets the windows or screens, and flashes the joint where the roof meets your house, which means fitting the metal that turns water away from that seam, so water goes where it should. Before anything gets closed in, we make sure the doors and windows open and shut right, because I won't hide a bad fit behind trim.
Most additions end up as either a four season sunroom you can heat and cool or a three season sunroom for the milder months, and we build both. If you're not sure which one fits how you'll use the room, that's the first thing we sort out together.
Why Rancho Cucamonga homeowners call us for sunroom additions
I measure and price it myself
I come out to look at the job and measure, and I'm on site with our own crew while they build. The person who priced your room is the one checking that it goes together the way it was planned.
Years spent fixing failed rooms
Before we started building in 2017, I spent years fixing leaky patio covers, sagging enclosures and sunrooms somebody built in a hurry. Taking those apart taught me where these rooms fail, and that's where we put the most care.
Permits pulled with the city
When your room needs a permit, we pull it and work with Rancho Cucamonga's building office through the inspections, after checking what the city wants for your address. A sunroom attached to your house falls under the state building code like any other addition, so we plan for that from the first drawing.
Licensed and insured for your house
We're licensed and insured, and our work is backed by our satisfaction guarantee. If something goes wrong while we're building, you're not the one left carrying it.
A sunroom only earns its cost if it stays dry and you can afford to finish it, so start by talking size and budget with the person who'll be on the job. Send us your project details or call (909) 360-4006.
Get a written price for your sunroom addition
Send the room size, the type you want and whether it goes on a deck, patio or new foundation. We reply within one business day to set up a free on-site estimate, with no obligation.

What happens after you call about a sunroom addition?
Call or send a message
Call (909) 360-4006 or use the form, and tell us roughly how big you want the room and what it'll sit on. We get back to you to set a time for me to come out.
I measure and talk use
I look at the space and what the room will sit on, take measurements and ask how you plan to use it. You get a written estimate with the price, so you know the number before anything starts.
We permit and build
Once you sign, we take care of the permit when the job needs one, and our own crew builds the room. I'm on the job with them the whole way.
Walk the finished room
I walk the finished room with you and we work the doors and windows together. You see how everything opens, closes and drains before we pack up.
Sunroom addition questions
What is the difference between a three season and a four season sunroom?
A four season room is fully enclosed, heated and cooled, with all-weather windows, while a three season room has no heating or cooling and uses uninsulated windows or screens. The choice comes down to how much temperature control you need in there. If you lean toward four season, plan the insulated windows and the wall, floor and roof insulation from the start, because adding them later can often cost more.
How much does a sunroom addition cost in Rancho Cucamonga?
A sunroom in Southern California usually costs about $110 to $190 per square foot, which is the going range across the region, not our price. Larger rooms that need a foundation and have heating and air conditioning sit at the higher end. Your own number comes from the written estimate after I measure.
Can a sunroom be built on my existing deck or patio?
It can, but a deck will typically need added beams, posts or footings to carry the room's weight, and it's worth planning for a local structural engineer to check whether yours is suitable. On a concrete patio, footings are needed where they have to reach frost line depth, the depth the ground freezes to, and where there's no frost depth they may only be required as the structure needs them. I look at what's under the room on the first visit, since that shapes the price.
How do I apply for a building permit for a sunroom in Rancho Cucamonga?
Rancho Cucamonga takes all permit applications online through its Online Permit Center, which you reach from the city's building and safety page. The online list names solar, reroofs and patio covers, not sunroom additions, and the city takes technical permit questions and other permits by email at EDRnotification@CityofRC.us. On our jobs, we handle that part for you.
What is the best way to make a sunroom more energy efficient?
Start with which way the windows face and how well they perform. One window guide found that windows facing mainly north use less energy than ones facing east, south or west, and high-performance windows and shading make those differences considerably smaller. If your patio faces south or west, ask about both when I come out to measure.
How do I take care of a sunroom roof and gutters?
Stay off the roof unless you need to be up there, and have the roof and gutters inspected once a year, which is what one sunroom maker's care guide advises. The same guide says to keep the weep holes clear, the small openings that let water drain out, so the room drains the way it should. Follow the care guide from your room's maker, since that's what decides how it should be kept.
