Pomona: older houses beside newer tracts
Pomona has a lot of older housing. The city has several historic districts and landmarks, and plenty of properties here are on the National Register. Away from the older neighborhoods near downtown, you get newer tract homes, so in one week I might measure a back porch on a house that's been added onto a few times and a slab patio behind a stucco tract house. If your house is one of the older ones, we check what the city wants for your address before we start. We see a similar spread of houses next door in Chino and up in Upland.
That mix shapes the job. On an older house, the question is usually what the roofline and the old patio can carry. On a newer one, it's how cleanly we can tie into stucco and a roof that was never planned for a room. I'd rather sort that out at the estimate than halfway through the build.

Sunroom work we do in Pomona
Patio-to-sunroom conversion
A lot of Pomona backyards already have a slab patio, and turning it into a room makes sense when that slab can carry the walls. I check its edges and thickness at the estimate, and if it can't carry a room, we add footings instead of hoping it holds.
Patio cover installation
Older houses here often have a patio cover that's been patched for years and still drips where it meets the house. We flash new covers into the wall and pitch them so water runs off the low side, away from your back door.
Sunroom remodeling
Some of our calls are for rooms that went up fast, with caulk where flashing should be and trim hiding the gaps. We open up the bad spots and fix where the water goes, and we get the doors and windows closing right before anything gets covered again.
Sunroom construction
On houses that have been added onto a few times, the walls are rarely square and the rooflines don't line up, so the room has to be built to the house you have. Our own crew handles the sunroom construction from footings to roof, and I'm on the job with them.
Four season sunrooms
If you want a room you use like the rest of the house, a four season sunroom with insulated walls and roof is the one to build. We tie it into your house so it feels like part of it, not a porch with windows.
Screen room installation
Plenty of older Pomona yards have big trees, and a screen room keeps the leaves and bugs out while still letting air through. We set the roof pitch and gutters so debris washes off, because a clogged edge is where these rooms start to leak.
What working in Pomona involves
In Pomona, building permits come from the city's Building Safety Division, which also reviews plans and does the inspections, so a sunroom's schedule depends on plan review and inspection visits as much as on our crew. Before we start, we check what the city wants for your address. When a job needs a permit, we pull it and work with Building and Safety through the inspections, which check the work against the state building code as the city has amended it. Businesses also apply for their Pomona business license through the city, so it's a fair thing to ask about when you compare contractors.
The price depends mostly on the room itself. That means its size, whether it's a screened room or a fully closed four season room, the glass and roof panels you pick, and whether your patio or deck can carry the room or needs new footings. Tying into an older roofline usually takes more work than a newer one, and adding power or lights adds to the cost. I come out, measure and put the price in writing, so the number you see is for your house. We're based in Rancho Cucamonga and do the same work in Rialto and the other cities around us, and when something big is on at Fairplex, we plan deliveries around the traffic.

Sunroom ideas for Pomona homes
Sunroom questions from Pomona homeowners
Do I need a permit to add a sunroom in Pomona?
Check with the city first, because the answer for your address comes from Building and Safety. Its Do I need a Permit? guidance is on the city's Building and Safety forms page. The work the city lets skip a permit includes things like fences no taller than 7 feet and block walls no more than 2 feet high, so don't assume a room falls in the same group. If your job needs a permit, we pull it, as I covered above.
When can I visit Pomona Building and Safety in person?
Building and Safety takes walk-ins Monday through Thursday, 7:30 a.m. to 6:00 p.m., at City Hall, 505 South Garey Avenue. City Hall is closed on Fridays, so plan around that. You can also call the office at 909-620-2371.
How much does a sunroom cost in Pomona?
The cost depends on the room you choose and on what your house needs to carry it, so I give you a written price after I measure. The biggest differences come from size, a screened room versus a closed one, and whether the patio underneath needs new footings. The estimate is free, and you can book it at (909) 360-4006.
Can I turn my old patio cover into a sunroom in Pomona?
Sometimes, but a lot of older patio covers in Pomona were never built to carry walls and glass. I look at the posts, the beam and where the cover meets the house, and I'll tell you plainly whether we can build on it or should start fresh.
How long does it take to get a sunroom built in Pomona?
Most of the wait usually comes before we build. That covers the design, the permit if your job needs one and getting materials in. During the build, the city's inspection visits set the pace, and we schedule our crew around them.
What causes a patio enclosure to leak on an older Pomona house?
Most leaks come from where the room meets the house. Usually there's caulk where there should be flashing, or a roof with too little pitch for water to run off. On older houses, uneven walls make that joint harder to get right, so we flash it properly and leave it where you can see it instead of hiding it behind trim.
