Learn MoreReach out by phone or through our contact form. We ask a few quick questions - where on your home you want the room, roughly how large, and whether you have an HOA. No commitment, no pressure. We respond within 1 business day.
We come to your home, measure the space, assess the existing structure, and walk through your options in person. You leave with a clear picture of the project scope and a written proposal. No surprises, no ballpark guesses.

"They finished the sunroom addition ahead of the timeline we agreed on, which I did not expect. The permit process was handled completely on their end - I never had to make a single call to the city. The room has been our most-used space in the house since the day it was done."
Daniel K., Lakewood, CA - Sunroom additions
"I had been putting off the patio enclosure for two years because I was worried about HOA approval. They prepared all the drawings and submitted everything to the board for me. The HOA approved it in about three weeks, and the construction went smoothly. I wish I had done it sooner."
Mia T., Artesia, CA - Patio enclosures
"Our four-season room stays comfortable even on the hottest afternoons in July. They walked us through the glass options during the estimate and explained why the low-E glass mattered for our situation. That conversation alone showed us they knew what they were doing."
James R., Norwalk, CA - Four season sunrooms
We respond within 1 business day - no obligation, no pressure. After you submit, someone from our office will call to schedule a free on-site estimate at a time that works for you. The estimate is done in person at your property so we can give you an accurate number, not a guess.

Yes - any permanent sunroom or patio enclosure in California requires a building permit before work begins. Skipping this step creates serious problems at resale. The California Contractors State License Board explains your rights as a homeowner at cslb.ca.gov.
Cerritos averages over 280 sunny days per year, with winters that rarely drop below 45 degrees. That mild climate means a three-season room is genuinely usable for most of the year. A four-season room makes sense if you want guaranteed comfort on the coolest nights.
Low-emissivity glass blocks solar heat while letting natural light through. Without it, a glass room in Cerritos can become uncomfortably hot by noon in July. California's energy code also requires new conditioned spaces to use glazing that meets specific performance standards.
If your Cerritos home is in an HOA - and many are - you need written approval from the architectural review board before your contractor can pull a city permit. The HOA review is separate from the city process and can take two to six weeks on its own.
The Los Angeles Basin has clay-heavy soils that expand when wet and shrink when dry. Over time, that movement shifts foundations that are not engineered for it. The National Association of Home Builders at nahb.org provides guidance on what to ask your contractor about foundation design.
From first call to finished room, most homeowners in Cerritos should plan for eight to twelve weeks. Permit review adds three to six weeks before construction begins. HOA approval runs alongside - and adds more time if your association has a slow review cycle.

If your current patio cover or porch is aging and you are already thinking about repairs, the cost of a proper enclosure is often not far off. Get a replacement quote alongside the repair quote - you may be closer to a permanent upgrade than you think.
An unpermitted addition can block your home sale, trigger removal orders, or require expensive retrofitting to legalize. In California, buyers and lenders look closely at permit history. A permitted sunroom is an asset; an unpermitted one can be a liability.
Start at least three months before you want the room finished. Permit review in Cerritos typically takes several weeks, and HOA approval adds more time. The best time to call is before you are in a hurry - so the timeline works in your favor.
For guidance on residential energy efficiency standards that apply to new sunroom additions, the U.S. Department of Energy window and glazing guide is a useful starting point. Contact us and we will walk you through what it means for your specific project.
Cerritos is a mid-size suburban city of about 49,000 residents in the southeast corner of Los Angeles County, bordered by Artesia, Norwalk, and Lakewood. The city was incorporated in 1956 and developed rapidly through the 1960s and 1970s, which is why most homes here are now 50 to 60 years old. That housing stock creates consistent demand for sunroom additions, patio enclosures, and conversions - the original patios and slabs have aged, and many families want to get more out of their outdoor space without moving. More information about the city is available on the Cerritos, California Wikipedia page.
The city is known for a few standout community landmarks. The Cerritos Center for the Performing Arts is the most recognized address in the city, hosting Broadway shows and national touring acts since 1993. The Cerritos Public Library is known regionally for its architecture and the aquarium inside the building. And the Cerritos Auto Square along Studebaker Road is one of the largest dealership complexes in the country - a landmark nearly every resident knows. We serve homeowners throughout all of these neighborhoods, from the streets near the performing arts center to the quiet blocks along the Artesia and Norwalk borders.
Owner-occupancy in Cerritos runs well above 70 percent, and many families have lived in the same home for 20 or 30 years. Long-term homeowners tend to invest in their properties, and a sunroom addition is one of the most practical upgrades in a city where home values are high and square footage is at a premium. We understand what homes here need - the clay-heavy soils that shift with the seasons, the seismic requirements that govern every foundation, and the HOA rules that affect exterior additions in many Cerritos neighborhoods. More demographics are available from the U.S. Census Bureau quick facts for Cerritos.
