Quality Cypress Sunrooms & Patios has been serving Cerritos homeowners with patio cover installation, sunroom additions, enclosed patio rooms, and all season room conversions since 2015. Most Cerritos homes were built in the 1960s and 1970s, and we understand what aging concrete slabs, clay soil movement, and 50 years of Southern California sun mean for a patio enclosure project - so we plan for those conditions from day one.

Cerritos summers push temperatures into the 90s, and most homes here have a rear slab that faces full afternoon sun with no shade at all. Our patio cover installation service gives Cerritos homeowners a covered outdoor area that stays dry through winter rains and cool enough to use through the hottest months - and it doubles as the structural starting point for a full sunroom enclosure when you are ready to take that step.
Cerritos homeowners who want a year-round room - not just a covered slab - benefit from an insulated all season room that handles Southern California heat in summer and stays comfortable through the wet months. We assess the existing patio slab for clay soil settlement and tree root damage before framing begins, because aging Cerritos slabs need that check before any structure goes on top of them.
Most Cerritos ranch homes have a rear patio slab that has been in place since the 1960s and has plenty of usable footprint. An enclosed patio room uses that existing slab without expanding the foundation, which keeps the project within the city setback requirements and significantly reduces cost compared to a full room addition. The result is a weathertight room that feels like part of the house, not a tacked-on structure.
Cerritos home values regularly exceed $700,000, and adding permitted living square footage is one of the best ways to protect and grow that investment. For homes where the existing slab is too small, too compromised, or positioned poorly for a conversion, a sunroom addition built off the rear wall gives you a proper new room with its own foundation and connection to the existing structure.
Cerritos patio enclosures need to handle clay soil movement, mature tree roots pushing up against slab edges, and intense UV exposure that degrades lower-grade frame materials and sealants within a few seasons. We build patio enclosures with commercial-grade framing and sealants rated for Southern California conditions - not catalog-grade systems that look fine in the first year but start failing by year three.
Cerritos has some of the most comfortable spring and fall evenings in the region, but an open patio still brings insects, afternoon glare, and the occasional Santa Ana dust event. A screen room extends the usable season on your Cerritos patio without the permit complexity or cost of a full enclosure - and the framing we install is compatible with glass or polycarbonate panels if you want to upgrade later.
Cerritos was developed almost entirely between 1960 and 1980, which means most homes here are between 45 and 65 years old. The concrete slabs, stucco exteriors, and any original patio structures from that era have been sitting through decades of Southern California heat, clay soil movement, and Santa Ana wind events. Cerritos sits on clay-heavy soils that swell when rain comes and shrink when the ground dries out - that repeated expansion and contraction is why so many Cerritos driveways, walkways, and patio slabs have cracked and settled even when they were poured well. The mature trees planted when these neighborhoods were first developed have had 50-plus years to grow roots under those slabs, and that root pressure is a major reason enclosures built on unexamined Cerritos slabs develop frame and connection problems within a few years.
On top of the soil and slab challenges, Cerritos homeowners deal with some of the highest UV exposure in the country through the summer months, Santa Ana wind gusts each fall that stress every connection on an attached outdoor structure, and winter rains that pool against foundations and slab edges on clay soil that does not drain quickly. Any patio cover or sunroom enclosure built in Cerritos needs materials and installation methods that account for all three of those seasonal forces - not just meet minimum code on a mild afternoon.
Our crew works throughout Cerritos regularly, and we understand the local conditions that affect sunroom contractor work here. Permits for projects in Cerritos are issued by the City of Cerritos Community Development Department, which handles building and safety for this incorporated city directly - unlike neighboring Lakewood, which contracts those services through Los Angeles County. We pull permits through Cerritos City Hall and know the city staff, review timelines, and specific submittal requirements.
Cerritos is a well-maintained city with strong community identity - residents near the Cerritos Center for the Performing Arts and those further out along the Studebaker Road corridor near the Cerritos Auto Square all tend to be long-term homeowners who invest in keeping their properties in good shape. Most of our project work here is on the single-story ranch homes that fill the residential streets between 183rd Street and the Artesia and Norwalk borders.
We regularly work in neighboring Lakewood to the northwest, where the housing stock is even older but the project demands are very similar. Whether your home is near the performing arts center or out in the quieter streets toward the Norwalk border, we cover all of Cerritos.
Reach us by phone or through the contact form and describe what you have in mind. We respond to all Cerritos inquiries within one business day and schedule the on-site estimate at a time that works for your schedule.
We visit your Cerritos home, measure the space, and inspect the existing slab for clay soil settling and tree root damage - two issues that affect nearly every older Cerritos property. We explain exactly what we find and give you a written fixed-price estimate that includes any slab prep work needed before framing, so there are no surprises mid-project.
We prepare and submit the permit application to the City of Cerritos and manage any follow-up with city staff. Once the permit is approved, we schedule your installation dates and confirm materials and crew assignment in advance.
Our crew completes the installation - slab prep first if needed, then framing, roofing, glazing, and finishing. We walk through the completed project with you before we leave to confirm everything meets the agreed scope and that you are satisfied with the result.
We serve Cerritos homeowners with free on-site estimates, written fixed-price quotes, and no-pressure consultations. Reach us today and we will be back to you within one business day.
(657) 337-7008Cerritos is a mid-size suburban city of about 49,000 residents in the southeastern corner of Los Angeles County, incorporated in 1956 after being converted from Dairy Valley farmland into a planned residential community. The city developed rapidly through the 1960s and 1970s, and today almost all of its housing stock consists of single-family ranch and traditional tract homes on modest lots of 5,000 to 8,000 square feet. Cerritos is one of the more affluent suburbs in Los Angeles County, with median home values consistently above $700,000 and a high rate of long-term owner-occupancy. Many families have lived in the same home for 20 to 30 years, which means deferred maintenance is common but so is genuine investment in quality when homeowners finally decide to improve their properties. You can learn more about the city of Cerritos on Wikipedia.
The city sits near the junction of the 91, 605, and 5 freeways, which makes it easy to access from Long Beach, Anaheim, and greater Los Angeles. The Cerritos Center for the Performing Arts on Park Plaza Drive is the most recognized landmark in the city and has hosted major touring acts since 1993. The Cerritos Public Library, opened in 2002, is nationally known for its distinctive architecture. Cerritos is bordered by Norwalk to the north, Artesia to the east, Lakewood to the west, and Buena Park to the south - making it a natural hub for our crew working throughout this part of Los Angeles and Orange County. We also regularly serve homeowners in Anaheim to the southeast, where the housing mix is more varied but the outdoor enclosure needs are similar.
