Services in Pomona, CA
Patio-to-sunroom conversion
A lot of Pomona backyards already have a slab and a cover, and closing that in is often the shortest path to a real room. We check how thick the slab is and what's under its edges first, because glass walls put weight where a patio table never did.
Deck-to-sunroom conversion
A deck framed for foot traffic usually isn't ready to carry walls and a roof. We open it up, check the posts and footings, and add what's missing before any room goes on top.
Sunroom remodeling
We see plenty of older add-on rooms here that leak at the house wall, fog up between panes or just sit empty, and that's where we remodel an older sunroom instead of starting over. We find out why it failed first, which is often what it's sitting on, and fix that before we touch the glass.
Custom sunrooms
Not every back wall is a straight run, and plenty of Pomona houses have bump-outs, low eaves or an old addition in the way. We size and shape the room around what's actually there instead of forcing a standard kit onto it.
Screen room installation
Some homeowners here just want the back patio usable in the evening without the bugs, not a full room. A screen room is lighter and asks less of the slab, so it's a good fit when the base is only fair.
Patio cover installation
Plenty of yards here start with bare concrete and nothing overhead. We build the cover with posts and footings sized so you can close it in later without tearing it out.
Pomona, CA properties and local conditions
Pomona has five historic districts and 27 historic landmarks, and a good number of other properties here are on the National Register, so a fair share of the houses we see have some age and character to them. A sunroom on a house like that should look like it came with it, so I check where your address sits before anything gets drawn, and we match the roofline, trim and window lines rather than bolting a kit to the back wall.
Out back, we mostly find patios and decks that were never meant to hold a room, and rooms added years ago that leak where they meet the house. Glass doesn't forgive a base that moves, so we sort out the base first.
Building a sunroom in Pomona: permits and what sets the price
Building permits in Pomona come from the city's Building and Safety Division, which also reviews plans and does the inspections, so it's the office that decides when we can start and when each stage can be closed up. We look up what your address needs, and when the job needs a permit, we handle the paperwork and work through the inspections with you. Business licenses run through the city as well, and we're licensed and fully insured. The price moves on what the room sits on, how big it is, glass or screen, the roof, and whether you'll use it all year, and the schedule moves on plan review and any foundation work, so your written estimate is where you see both for your house.
We come over from Hacienda Heights for Pomona jobs, and the same crew builds in West Covina and down in Fullerton. Most Pomona houses we see already have something out back, a slab, a cover or an old enclosure, so a lot of our work here starts with deciding what to keep and what has to go.

(626) 269-6285How it works when you call us about a Pomona sunroom
Call or send the form
You reach us by phone or the form, and we set a time for me to come out. It helps if you're home so we can talk about how you'll use the room.
I look, measure and ask
I check the slab or deck, take measurements and ask what the room is for. You get a written estimate that spells out what's included before you sign anything.
We handle the permit side
When the job needs a permit, we do the paperwork with the city and set up the inspections. Plan review comes before building, so it sets the start date more than we do.
We build and walk through
My crew and I build the room, foundation work first. When it's finished, I walk through it with you before we call it done.
Frequently asked questions
How much does it cost to build a sunroom in Pomona?
The biggest factors are what the room sits on and what kind of room you want, and you get your own figure in a written estimate after I've seen the site. A sound slab or deck keeps the cost down, while one that needs new footings adds to it. Full glass for year-round use costs more than a screen room, and size, roof style and any electrical work move it too.
How do I find out if my sunroom needs a permit in Pomona?
Ask the city's Building and Safety Division, which has Do I need a Permit? guidance on its forms page. The city's list of exempt work names things like fences up to 7 feet and low walls, not rooms, so don't read a sunroom into it. We check for your address and handle the paperwork when one is needed.
When can I visit Pomona Building and Safety in person?
Monday through Thursday, 7:30 a.m. to 6:00 p.m., at City Hall, 505 South Garey Avenue. City Hall is closed on Fridays, so don't plan a Friday trip. You can also call Building and Safety at 909-620-2371.
Can you build a sunroom on my existing patio slab in Pomona?
Often yes, if the slab is thick enough and has a footing, a deeper strip of concrete, along the edge where the walls will sit. A patio slab does a fine job holding up a grill, but nobody asked it to hold up a glass room, so I check before quoting. If it isn't up to it, we add footings or pour new.
How long does it take to get a sunroom built in Pomona?
Most of the wait usually comes before the build, while plans go through the city's review. After that, the schedule turns on how much foundation work your site needs, when the glass and panels arrive and when inspections can be booked. Your estimate lays out what applies to your job.
What causes a sunroom to leak where it meets the house?
Usually it's the joint between the sunroom roof and the house wall, where the flashing, the metal strip that turns water away, was skipped, cut short or pulled loose as the room settled. If the base under the room is sinking, it'll keep opening that joint back up. That's why we check what's underneath before we reseal anything.
About Pomona, CA
Pomona is a big city, and the houses change a lot from one part to the next, from older blocks near downtown to newer tracts farther out where the yards and slabs are different again. We see a mix of original patios, decks added later and rooms someone enclosed decades ago, much like the older streets we work on in La Puente.
That mix is why no two Pomona jobs start the same way. On an older house, the work is mostly fitting the room to what's there, and on a newer one it's mostly finding out what the slab can carry.
