Learn MoreReach out by phone or through the contact form. We respond within 1 business day. This first conversation is about understanding your space and what you want to use it for - no commitment required. Tell us roughly how large the area is and we can give you a ballpark range before we ever visit.
We come to your home, measure the space, check the existing foundation or patio slab, and talk through your options. This visit is free and comes with no obligation. We look at sun orientation, the wall your room will attach to, and any HOA requirements that might shape the design. After the visit, you receive a written proposal with a clear price.
Once you approve the design, we submit the permit application to the City of Hawthorne on your behalf. When permits are approved, construction begins. We handle every phase - foundation, framing, glass, electrical, and final inspection. When the crew leaves, you do a full walkthrough so everything is right before we call it done.
We carry both general liability insurance and workers compensation coverage on every project. You can verify our California contractor license through the CSLB before signing anything - we encourage it.
We have worked on homes across the South Bay since 2019. We know Hawthorne's housing stock, the City's permit process, and what the marine air does to materials over time. That local knowledge saves you headaches.
You get a written estimate after a real site visit - not a number pulled from a website form. We measure your space, check your slab, and talk through your options before quoting a price. No pressure, no commitment required.
We pull every required permit through the City of Hawthorne and coordinate all city inspections. When the job is done, you have documentation that your addition is legal - which matters when you sell.

"They finished the permit process faster than I expected and the construction took about three weeks. I was worried about the room getting too hot because we face west, but they installed glass that actually keeps it comfortable. I sit out there every morning now."
Maria T., Hawthorne - Four Season Sunrooms
"Our old patio slab was cracked but they were able to work with it and save us the cost of a full pour. The screen room has been the best addition to our house - we eat dinner out there almost every night and the bugs are finally not an issue."
James R., Inglewood - Screen Room Installation
"I had an HOA and was nervous the whole project would fall apart over approvals. They handled all the paperwork, got HOA sign-off before submitting to the city, and the whole thing went smoothly. The enclosed patio looks like it was always part of the house."

Yes - more than almost any other decision. Low-emissivity glass reflects solar heat before it enters the room while still letting in light. In a sun-heavy climate like Hawthorne's, the difference between standard glass and low-e glass can be 15 to 20 degrees on a summer afternoon.
Hawthorne's mild coastal climate makes three-season rooms a strong value. Temperatures rarely drop below the mid-50s, so a non-climate-controlled room is usable for most of the year. A four-season room makes sense if you want full comfort during heat waves or the occasional cold January night.
An unpermitted addition can delay or derail a home sale. Buyers' lenders often require unpermitted work to be removed or legalized before closing - at your expense. The California Contractors State License Board recommends verifying your contractor's license and confirming they pull permits. Visit cslb.ca.gov to check any contractor's license status.
Coastal moisture and salt air accelerate rust on metal components. Aluminum framing with a powder-coat finish and vinyl window frames resist corrosion far better than bare steel. A contractor who has worked in the South Bay will specify materials suited to this environment.
If you already have a patio cover or older porch, have a contractor assess whether the structure can be upgraded before committing to a full teardown. Reusing an existing slab in good condition can significantly reduce project cost.
A properly insulated four-season room with the right glass can actually reduce heat gain in adjacent rooms by acting as a thermal buffer. The U.S. Department of Energy provides guidance on energy-efficient windows and room additions at energy.gov/energysaver - worth reading before finalizing your glass selection.

Learn more about our companyThe best time is when your outdoor space is clearly underused and you have a clear idea of how you would use a covered room. Projects started in fall often benefit from shorter permit wait times before the busy spring construction season.
Ask each contractor to use the same room dimensions and glass specifications in their bids. A low bid that uses standard glass instead of low-e glass is not comparable to a higher bid that includes proper heat management. The National Association of Home Builders publishes consumer guidance on comparing bids at nahb.org.
A clear scope of work, itemized materials and labor, a payment schedule tied to milestones, and confirmation that the contractor will pull all required permits. If a contract does not name the permit process explicitly, ask for it in writing before signing.

Hawthorne is a South Bay city in Los Angeles County with a population of around 88,000 people. The city sits just a few miles from Los Angeles International Airport and roughly four miles from the Pacific Ocean. It borders Inglewood, Lawndale, El Segundo, and Gardena. The combination of consistent sunshine and coastal marine air shapes what homeowners here need from any outdoor room addition - heat management and moisture resistance both matter.
Most homes in Hawthorne were built between the 1940s and 1970s during the postwar boom. The city is known as the birthplace of the Beach Boys and is home to SpaceX headquarters on Jack Northrop Avenue. Community gathering often happens at the Hawthorne Memorial Center, the city's main public venue. Median home values have risen sharply over the past decade, giving homeowners a strong reason to invest in improvements that protect and grow that value.
The marine layer that rolls in off the coast - especially during June Gloom - means patios and outdoor spaces are often damp and chilly for weeks at a stretch, even in what looks like summer. That coastal moisture also affects materials: salt air eats through bare metal faster than most homeowners expect, which is why we specify aluminum framing and vinyl components suited to this environment. Hawthorne Sunrooms & Patios has been building sunrooms and patio enclosures in Hawthorne since 2019 and understands what the local housing stock and climate demand. If your home is in the South Bay area, we can typically schedule a free on-site estimate within the same week.
