Compton Sunrooms & Patios builds patio enclosures, sunroom additions, and screen rooms for homeowners across Gardena, CA. We have served the South Bay since 2018 and handle all City of Gardena building permits from the application through the final inspection.

Gardena's older homes often have a concrete slab at the back that has been sitting open for decades. We enclose those existing pads with glass or screen panels, turning them into protected living space without disturbing your foundation or the rest of your home. A patio enclosure is one of the most cost-effective ways to add usable square footage to a postwar Gardena home.
Gardena lots are modest in size and mostly built out, so a traditional room addition can feel like a major undertaking. A sunroom addition uses the footprint of your backyard or side yard and delivers a bright, enclosed room without the disruption of full interior construction.
Gardena's warm evenings are pleasant, but insects can make outdoor sitting uncomfortable from spring through fall. A screen room gives you full ventilation and that outdoor feel while keeping the bugs out, which is a practical solution for the South Bay's warm-season nights.
Gardena summers are intense enough that a basic glass room will overheat quickly without the right glazing. Our four-season builds use insulated frames and low-e glass designed for Southern California's sun angles so the room is genuinely comfortable, not just functional in the cooler months.
Year-round UV exposure in Gardena degrades wood frames and exterior paint faster than most homeowners expect. Vinyl frames resist fading and cracking without painting or staining, which makes them a low-maintenance fit for homes in this part of Los Angeles County.
Many Gardena homeowners have a covered patio or aluminum shade structure that is past its useful life. Converting that existing structure into a finished sunroom uses the footprint you already have and avoids the cost of demolishing and rebuilding from scratch.
Most of Gardena's housing stock was built between the 1940s and 1960s, during the postwar suburban boom in the South Bay. These homes are typically one-story, wood-frame construction with stucco exteriors and concrete slab foundations. At 60 to 80 years old, many of the concrete pads have cracked and settled due to Gardena's clay-heavy soils, which expand when the winter rains arrive and shrink back down during the dry summer. That soil movement is the main reason a foundation check is not optional here - it is part of every estimate we produce. A contractor who skips this step is setting up a mid-project surprise.
Gardena's climate also shapes how every sunroom we build here gets designed. The city averages more than 280 sunny days per year, and summer afternoons regularly reach the upper 80s. A room built with standard glass will overheat by early afternoon, making it unusable for most of the year. We use glass that manages solar heat gain without blocking natural light, and we design ventilation into every enclosure so air moves through the space on warm evenings. Southern California's seismic requirements add another layer - any structure we attach to your home is anchored to handle lateral movement, which makes the room safer and the attachment to your house permanent, not just cosmetic.
Our crew works throughout Gardena regularly, and we understand the local conditions that affect sunroom and patio enclosure work here. The city is almost entirely built out - under 6 square miles with small lots packed closely together - which means access around the sides and backs of homes is limited. We plan every project around that reality, staging materials efficiently and working carefully around neighboring fences and property lines.
Gardena sits in the South Bay, bordered by Torrance to the south, Hawthorne to the west, and Compton to the east. The 110 and 91 freeways connect the city in every direction, which makes getting our crew and materials out here straightforward. We know the neighborhoods around Rowley Park on the south end, the streets along Vermont and Western Avenues through the center, and the older residential blocks near the Gardena Valley Japanese Cultural Institute. The housing stock throughout is remarkably consistent - postwar single-family homes on modest lots with concrete pads that have been sitting outside for decades.

Homeowners in Hawthorne to the west deal with very similar postwar housing conditions, and we serve that community regularly as well. If you are in Gardena or a neighboring South Bay city, you are in our active service area.
We ask a few quick questions about your home and your goals. You will hear back within one business day. No commitment is required at this stage.
We come to your Gardena home, look at the slab or foundation, measure the space, and walk through your options. A detailed written estimate follows within a few days. This is also where we address cost concerns - what is included, what is not, and what foundation prep, if any, is needed.
We prepare and submit the building permit application to the City of Gardena's Building and Safety Division. You do not need to visit any city offices. We keep you updated on the review status until approval comes through.
We complete the build, coordinate all required city inspections, and do a final walkthrough with you when the work is done. You receive the signed permit paperwork for your records.
We serve all of Gardena and respond within one business day. Tell us what you are working with and we will give you a straight answer - no pressure, no sales pitch.
(424) 447-1306Gardena is a city of about 60,000 people packed into under 6 square miles in the South Bay area of Los Angeles County. It is a fully built-out, established city with almost no undeveloped land left. The residential neighborhoods are dense and walkable, with a mix of single-family homes and small apartment buildings. Most of the housing stock dates from the 1940s to the 1960s - one-story, stucco-clad homes on small lots, typically 5,000 to 7,000 square feet. Many families have lived in Gardena for multiple generations, which means homes here have often passed through several rounds of repairs and updates. Gardena has historically been known for its large and long-established Japanese American community, centered in part around the Gardena Valley Japanese Cultural Institute.
