Sunroom Contractor in Pomona, CA - Rooms Built to Fit Older Homes and Yards
Comfortview Corona Sunrooms & Patios is a sunroom contractor based in Corona that builds sunrooms, patio enclosures and patio covers for Pomona homeowners who want to use their back patio or deck for more of the year.

Pomona as we see it from the back patio
Many of the Pomona homes we're called to are older, and it shows when I walk around to the back of the house. Often there's a concrete patio that was poured long ago, a cover that was added later by someone else, and a stucco or wood wall that's been painted more than once. Pomona also sits in a different county from our base in Corona, just across the line from Chino and Chino Hills, so I treat each address here on its own terms rather than assuming it works like home.
That's what shapes a sunroom job here. A room is only as good as the slab under it and the wall it seals against, so on older houses I spend more of the first visit checking those two things than talking about glass.
Services in Pomona, CA
Patio enclosures
Plenty of Pomona backyards already have a slab and a cover, which makes patio enclosures a natural place to start. We check that the slab is level and the posts are sound, then close in the sides with walls, windows and a door sized to your opening.
Patio cover installation
Older aluminum and wood covers here have often outlived their fasteners or sag where they meet the house. We build a new cover tied properly into your wall and size the posts so you can enclose it later if you decide to.
Sunroom additions
When an existing slab is too thin or out of level, we'd suggest a true addition on new footings rather than building over a problem. It costs more up front, but the room sits on concrete we've poured and checked ourselves.
Three season sunrooms
Many homeowners here want a covered, closed-in place to sit without heating and cooling another room. A three season room uses lighter glass or vinyl panels over a simpler frame, so it usually costs less than a fully insulated room.
Four season sunrooms
If you want the room to work like the rest of the house, with insulated walls, roof and glass, a four season room is the better fit. On older homes we look closely at how the new roof meets the old one, because that joint decides whether the room stays dry.
Sunroom remodeling
Some Pomona houses already have an enclosed room from years back, with cloudy panels, sticking windows or a leak at the wall. We'd suggest fixing what's failing before adding anything, and we'll tell you plainly which parts are worth keeping.
Working in Pomona: permits, plans and what moves the price
In Pomona, building permits come from the city's Building and Safety Division, which also reviews construction plans and does the inspections. That means your schedule usually turns on plan review and when inspections can be booked more than on our time building, so I check what the division expects for your address before anything goes on the calendar. We're licensed and insured, and when your job calls for a permit, we prepare the paperwork and work through the process with you. The price moves with the room type, its size, the glass and roof panels, any electrical work, and whether your slab and cover can carry a new room, and your written estimate spells out each of those for your house.
Pomona's streets carry a lot of city trees, about 37,000 public trees in parkways, parks and other city property, so we stage panels and framing in your driveway or yard and keep clear of the trees out front. As a sunroom contractor in Corona, CA, we're a little farther from Pomona than from Home Gardens, but the planning and the crew are the same, and we're glad to hear from homeowners up this way.
Why Pomona homeowners call us about the patio out back
On older houses, the patio slab was rarely poured with a room in mind. It may be thin, cracked or sloped away from the house to drain, which is fine for a table and chairs but not for walls and glass. We check the slab's thickness and level on the first visit and tell you whether we can build on it, repair it, or need new footings, before you're asked to choose a room.
Many homes here are single-story with a low roofline, which limits how high a sunroom roof can tie in. We plan the roof pitch and panel thickness around that line so the room doesn't feel cramped and water runs away from the house.

Pomona sunroom questions we hear often
Do I need a permit to build a sunroom in Pomona?
Pomona's list of work that can skip a permit covers fences no taller than 7 feet and low walls of about 2 feet that aren't holding back extra load, not sunrooms or patio enclosures, so don't plan on a sunroom being exempt. The city's forms page has a Do I need a Permit? guide, and we confirm what your address needs before we schedule anything.
When can I visit Pomona Building and Safety in person?
Building and Safety takes walk-ins Monday through Thursday, 7:30 a.m. to 6 p.m., at City Hall, 505 South Garey Avenue. City Hall is closed on Fridays, so call 909-620-2371 first if you'd like to check something before you go.
How much does a sunroom cost in Pomona?
The cost depends mostly on the room type, its size and what it sits on, so we give you your figure in writing after I've measured. A screen or three season room usually costs less than an insulated four season room. On older Pomona houses, the biggest swing is often whether the existing slab can be used or needs new footings.
What is the best way to turn a patio cover into a sunroom in Pomona?
Start by having the slab and the cover checked, because an enclosure is only as sound as the posts and concrete already there. If both are in good shape, enclosing them is usually the simplest route, and if not, we'd suggest a new cover or footings first rather than closing in a problem.
Can I add a sunroom to an older or historic home in Pomona?
In most cases we can, but if your house might be historic it's worth asking the city early, since Pomona has 5 historic districts and 27 historic landmarks, and numerous properties here are on the National Register of Historic Places. On any older house, we plan how the new roof and walls meet the existing siding or stucco so the joint stays sealed and the room looks like it belongs.
How long does it take to build a sunroom in Pomona?
The time on site depends on the room type and size, and the longer wait usually comes before we start, while plans and any permit go through the city. I'll walk you through the order of each step at the estimate so you know what the schedule depends on before you commit.
