Orange Sunrooms & Patios builds patio enclosures, four season sunrooms, and custom screen rooms throughout Tustin - handling all city permits and responding within one business day.

Tustin properties - whether postwar tract homes or newer Tustin Legacy builds - commonly have exposed concrete patios that see intense summer sun and occasional Santa Ana wind damage. A professionally built patio enclosure turns that unused slab into a weather-protected room you can actually use throughout the year.
Tustin summers regularly climb above 90 degrees, and the city sits close enough to the inland heat corridor that even newer homes feel it. A four-season sunroom with insulated walls and a mini-split HVAC unit stays comfortable in July and in January, making it usable space for every month of the year.
Tustin evenings are pleasant for much of the year, but fall wind events and the warm inland air bring insects that make sitting outside less enjoyable. A screen room captures the outdoor air and natural light while keeping bugs and debris out, and it fits naturally on the covered patios common in Tustin neighborhoods.
Tustin has a strong mix of single-family homes on lots ranging from 5,000 to 8,000 square feet, with enough yard space for a meaningful room addition. A sunroom addition adds square footage that shows up on the listing when you sell, and with Tustin median home values above $700,000, the investment makes sense.
Tustin homes span a wide range of styles - Victorian and Craftsman in Old Town, postwar ranch houses in the established neighborhoods, and contemporary two-story homes in Tustin Legacy. A custom design matches the roofline, materials, and proportions of your specific house so the addition looks intentional.
Many Tustin homeowners want shade over their patio without a full enclosure. A solid patio cover - aluminum, wood, or insulated - blocks direct sun and lowers the temperature underneath enough to make the patio usable on summer afternoons, which is the main reason most Tustin backyards go unused from June through August.
Tustin is not a uniform city when it comes to housing. The Old Town area has some of the oldest residential properties in Orange County, with homes from the 1880s through the 1930s that have wood siding, older foundations, and construction methods that predate modern building codes. Adding a sunroom to a property like this requires a different approach than adding one to a 1970s ranch house or a 2010 Tustin Legacy home. Getting the structural connection right - and making sure it passes the City of Tustin Community Development Department inspection - depends on understanding the age and construction type of your specific property.
The clay soils common throughout Tustin and much of Orange County expand when wet and contract when dry. This seasonal movement is the main reason driveways crack, patios heave, and slab foundations develop gaps over time. A sunroom that is not designed with this soil behavior in mind can develop gaps at the connection point with the house, drafts, and drainage issues within a few rainy seasons. We engineer the foundation detail to account for this movement, which is what separates a sunroom that holds up for decades from one that needs repairs in year three.
Our crew works throughout Tustin regularly, and we understand the local conditions that affect sunroom contractor work here. Tustin sits in the middle of Orange County, bordered by Santa Ana, Irvine, and Orange, with the 5 and 55 freeways running through the city - which means we can reach any Tustin neighborhood quickly without a long drive. We are familiar with the city permit process and know how project timelines run for residential additions here.
From the Victorian-era homes along El Camino Real in Old Town Tustin to the newer developments built on the former Marine Corps Air Station site - now Tustin Legacy - we have worked on properties at both ends of the city's housing spectrum. The old blimp hangars visible from much of the Tustin plain are a useful landmark for describing where jobs are located, and we know the streets and neighborhoods on both sides of them. Tustin Marketplace and the commercial corridor along Red Hill Avenue mark the center of the city where many of the postwar ranch home neighborhoods sit.
We also serve nearby Santa Ana and Orange, both of which border Tustin directly. If your property is near a city line or you want a contractor who knows this part of central Orange County well, we cover all three cities.

(657) 391-1155Tustin is a city of about 80,000 people in the center of Orange County, with a housing stock that spans more than a century of construction. The Old Town Tustin historic district along El Camino Real contains Victorian and Craftsman-era homes built as far back as the 1880s, making it one of the older residential neighborhoods in the county. Most of the city's mid-20th century housing - single-story ranch houses with stucco exteriors and attached garages - fills the established neighborhoods between Old Town and the city's eastern edge. These properties typically sit on lots of 5,000 to 8,000 square feet with concrete patios and driveways that have been in place for 50 or more years.
The Tustin Legacy development on the former Marine Corps Air Station site has added a different type of housing to the city - larger two-story homes, planned communities with HOAs, and properties built between 2005 and the mid-2010s that are now reaching the age where first-generation maintenance and upgrades are coming due. The two enormous wooden blimp hangars left over from the former air station are still standing near the Tustin Legacy area and remain one of the most recognizable landmarks in the region. Neighboring Irvine to the south and Orange to the west border Tustin directly, and we serve all three communities.
