Generic kits never quite fit. We design each custom sunroom from scratch to match your Pomona home's roofline, exterior finish, and the way you actually want to use the space.
Custom sunrooms in Pomona are designed and built specifically for your home - not assembled from a pre-packaged kit - and most projects take eight to fourteen weeks from permit submission through final inspection, with the room sized, framed, and glazed to match your existing structure.
If your patio sits empty every summer because the heat drives you inside, or you need a dedicated home office that feels separate from the rest of the house, a custom sunroom solves both problems at once. Unlike a screen room or patio cover, a properly built sunroom is a real room - one you can use on a January morning and a July afternoon. Many Pomona homeowners pair a custom sunroom project with our sunroom construction service when they want a fully managed build from foundation to finish, or with sunroom design when they want to develop the layout and material plan before committing to a contractor.
Pomona's mix of mid-century homes, HOA neighborhoods, and intense summer heat means every project needs to be thought through carefully - and that starts with a site visit, not a brochure.
Pomona temperatures regularly climb past 95 degrees from May through September, and an uncovered or screen-only patio becomes uncomfortable by mid-morning. If your outdoor space sits empty for months every year, you are losing the full value of your property. A custom sunroom with the right glass lets you reclaim that space year-round.
Many Pomona homes built in the 1950s and 1960s have modest square footage that no longer fits a growing family. Moving up in the current market is expensive, and a custom sunroom adds a real, usable room without the cost and disruption of a full structural addition. It can serve as a home office, a playroom, or a place to entertain.
If you have an older aluminum patio cover or screen enclosure that lets in bugs, leaks in rain, or sags in places, that structure is already past its useful life. Replacing it with a proper custom sunroom gives you something more durable, more comfortable, and far more valuable - without starting from scratch in a bare yard.
A kit addition bolted onto the back of a mid-century Pomona home looks exactly like what it is. If resale value or curb appeal matters to you, the room needs to match your existing roofline, exterior materials, and proportions. That is only possible with a custom-designed build - not a pre-packaged solution.
We handle every part of a custom sunroom project: site assessment, design, permit submission, foundation work, framing, glass installation, electrical, and final inspection walkthrough. If your project involves a structural upgrade to an older Pomona home, we address that during the assessment phase so it does not become a mid-project surprise. Homeowners who want a detailed plan before committing to a build can start with our sunroom design service, where we work through layout, materials, and glass options together.
For homeowners who want a complete turnkey build managed from the first nail to the final inspection, our sunroom construction service covers the full process. We also offer standalone design consultations for homeowners who want to develop a plan before selecting a contractor - so you can make an informed decision without pressure.

Pomona's summer heat is real - temperatures regularly exceed 95 degrees from late May through September, and the sun angle in the eastern San Gabriel Valley makes afternoon heat intense. A custom sunroom built for this climate uses glass specifically rated to reduce heat gain, so the room stays comfortable without becoming an oven by 10 a.m. This is not a detail you can skip or resolve with a ceiling fan alone. Homeowners near Diamond Bar and throughout the western Inland Empire face the same summer heat challenges, and the glass and ventilation decisions we make at design time determine whether you actually use the room in July.
Pomona also has a large share of mid-century homes - many built in the 1940s through 1960s - and attaching any addition to these structures requires a contractor who understands what those older walls and rooflines involve. California's seismic requirements add another layer: every custom sunroom must be framed and anchored to withstand earthquake forces, which affects the foundation design and how the room ties into your home's existing structure. Homeowners in Chino Hills and other nearby communities face similar building code requirements, and a contractor familiar with the local permit process handles this correctly from the start. The California Contractors State License Board lets you verify any contractor's license in about two minutes - a step worth taking before signing anything.
We respond within one business day. During the first conversation we ask a few basic questions - where on your home you are thinking, how you plan to use the room, and roughly what budget range you have in mind - so the site visit is actually useful.
We come to your home, measure the space, and check the existing structure - the wall, roofline, and foundation. This visit typically takes one to two hours and is the best opportunity to share your ideas. You receive a written, itemized quote afterward with no obligation.
After you sign a contract, we submit plans to the City of Pomona's Building and Safety Division. Permit approval typically takes two to six weeks. If your neighborhood has an HOA, we submit the architectural review request at the same time so both run in parallel.
Once permits are approved, we handle foundation, framing, glass, electrical, and finishing. A city inspector signs off on the completed work. We walk you through the finished room, answer your questions, and make sure you have all permit paperwork for your records.
No obligation. We come to you, take measurements, and give you a written quote.
(909) 729-4969We specify glass rated for the solar heat gain conditions of Pomona's climate zone, not a one-size product used across different regions. This means the room you get is comfortable in July, not just in October.
Every project we build in Pomona goes through the full city permit and inspection process. You receive the final inspection sign-off for your records - protection that matters when you sell your home or file an insurance claim. The National Association of Home Builders recommends verifying that any contractor pulls permits in their own name - a sign they are licensed and accountable.
Before work starts you have a written, itemized estimate. We flag potential variables - like what might be found inside an older Pomona wall - before you sign, not after work is underway. The number you agree to is the number you pay.
We design each addition to align with your home's roofline, exterior materials, and proportions. Pomona has strict HOA rules in many neighborhoods, and a custom-matched design moves through architectural review more smoothly than a kit that clearly does not belong.
Every detail - from the foundation anchoring required by California seismic code to the glass rating that keeps the room livable in August - is addressed before the first board is cut. That is what separates a room you are proud of from one you have to explain.
