Learn MoreReach out by phone or contact form and tell us what you have in mind. We will ask a few questions about your space and how you plan to use the room. No commitment needed - this first conversation is just about figuring out whether we are a good fit. We respond within 1 business day.
We visit your home, measure the space, and look at your existing foundation and yard access. You get a written proposal with a fixed price, a clear scope, and a realistic timeline. We also walk you through the permit process and any HOA considerations that apply to your neighborhood. No surprises after you sign.
Once permits are approved and the contract is signed, our crew handles everything - foundation, framing, glass, finishes, and city inspections. We keep you updated at each stage and call before spending anything outside the agreed scope. At the final walkthrough, you get permit documentation to keep in your home records.
We hold a current California Contractors State License Board (CSLB) license and carry general liability insurance on every project. You can verify our license before signing anything.
Every estimate is done in person at your home - not over the phone with a number we make up. You get a written proposal with a fixed price before any work begins.
We have been serving Pomona and the surrounding Inland Empire cities since 2015. We know local permit requirements, HOA processes, and what materials hold up in this climate.
We respond to every inquiry within 1 business day. Every project comes with a written timeline so you know what to expect and when - not a vague promise of "a few weeks."

They finished our sunroom addition in just under six weeks, which was exactly what they told us at the start. The glass they recommended keeps the room comfortable even on the hottest afternoons - we have been eating dinner out there all summer.
Maria T., Pomona - Sunroom additions
Our HOA had a lot of requirements for the patio enclosure, and the team handled all of it. They prepared the submission, responded to the association's questions, and we never had to get involved. The room turned out exactly the way we wanted.
James R., Ontario - Patio enclosures
I was nervous about the permit process because I had heard stories about delays. They were upfront about how long the city review would take, and they kept us posted the whole way through. No surprises, no extra charges.

Premier Pomona Sunrooms & Patios is based in Pomona, CA and serves 12 cities across the Inland Empire, including Ontario, Diamond Bar, Chino, and West Covina. Most of our customers are within a short drive of our office, which means we can typically schedule a same-week estimate and keep a regular crew on your project from start to finish.
Yes - significantly. Standard double-pane glass without a heat-blocking coating can turn a south- or west-facing sunroom into an oven by July. Low-emissivity glass reflects heat while still letting in natural light, and in Pomona's climate, it is the single most important specification you will choose. The U.S. Department of Energy has detailed guidance on window performance at energy.gov. Read the U.S. Department of Energy window performance guidance to understand the trade-offs.
Yes, every time. The City of Pomona requires a building permit for any room addition, including sunrooms and patio enclosures. Skipping the permit creates real legal and financial risk - unpermitted work can surface during escrow and cost you thousands to resolve. A licensed contractor pulls the permit before work begins, and a city inspector confirms the work is safe before the project closes.
Santa Ana winds blow through the Pomona Valley every fall and winter, with gusts that can exceed 50 mph during strong events. A properly built sunroom in this region is anchored to resist wind loads - not just designed for a calm spring day. Ask any contractor you consider how the structure is anchored to your home and what wind load specifications their framing meets.
Possibly. Many Pomona homes were built between the 1940s and 1970s, and some have older foundations, outdated electrical panels, or exterior walls that need reinforcement before a room addition can be attached. A thorough site assessment before you sign a contract is how you find this out - not mid-project when the crew is already on-site.
Pomona gets mild winters but brutal summers. A three season sunroom works well for spring and fall but can get uncomfortably hot without air conditioning in July. A four season room adds full insulation and a dedicated cooling system, making it usable on the hottest days. If you plan to use the room in the middle of summer, the four season option is worth the additional investment.
If your neighborhood has a homeowners association, you need written approval from the architectural review committee before your contractor can even apply for a city permit. HOAs commonly review exterior materials, roofline compatibility, and placement. Getting approval before you finalize your design - rather than after - is the one step that saves homeowners the most money and frustration.
Premier Pomona Sunrooms & Patios is a licensed and insured sunroom contractor company based in Pomona, CA, serving 12 cities across the Inland Empire since 2015. We hold a current California Contractors State License Board (CSLB) license, which is verified and publicly searchable at the CSLB website before any homeowner signs a contract. Over the years we have completed hundreds of sunroom additions, patio enclosures, and custom room projects across the eastern San Gabriel Valley and the western Inland Empire.

A three season room makes sense when you want to extend your outdoor time through spring and fall without paying for full climate control. In Pomona, that means a room that works well from October through May - and on cooler summer mornings. If you plan to use the space in July, consider the four season option instead.
A cracked or uneven slab is not a dealbreaker, but it needs to be addressed before an enclosure goes up on top of it. Your contractor should inspect the slab during the site assessment and include any repair costs in the written proposal. Discovering slab problems mid-project is one of the most common causes of unexpected costs.
It depends on how the room is classified. A fully conditioned, permitted sunroom that is connected to the home's heating and cooling system may count as conditioned square footage. An unheated three season room is typically listed separately. Your contractor and a local appraiser can clarify how your specific project will be classified.
The National Association of Home Builders publishes resources on room addition standards that are worth reviewing before your first contractor conversation. When you are ready to take the next step, call us at (909) 729-4374 or fill out our contact form.
Pomona is one of the larger cities in the eastern San Gabriel Valley, covering about 23 square miles with a population of over 150,000 residents. The city sits at the intersection of Los Angeles County and the Inland Empire, bordered by Ontario, Chino Hills, Diamond Bar, and Claremont. It is home to Cal Poly Pomona, one of the largest universities in the Cal State system, and the Fairplex, home of the Los Angeles County Fair - two landmarks that nearly every local resident knows.
A large share of Pomona's housing was built between the 1940s and 1970s, with many ranch-style and bungalow homes on modest lots across the city. The Lincoln Park neighborhood is particularly well known for its concentration of Victorian and Craftsman homes from the late 1800s and early 1900s. This older housing stock means sunroom and patio projects here often involve a site assessment of the existing foundation and exterior wall before design decisions are finalized - something we account for in every estimate we give. The region also experiences summer heat waves above 100 degrees Fahrenheit, Santa Ana wind events each fall, and periodic wildfire smoke from surrounding foothill areas, all of which shape how we design outdoor living spaces here.
Whether your home is near the Fairplex, out by Cal Poly, or in one of the older neighborhoods near downtown Pomona, Premier Pomona Sunrooms & Patios is a local contractor that knows what these homes need. We have worked in neighborhoods throughout the city and understand the permit process, the common HOA requirements, and the material choices that hold up in this specific climate.
