Redondo Beach Sunrooms & Patios installs patio covers, sunroom additions, and enclosed patio rooms for Lomita homeowners - including patio-to-sunroom conversions and screen room installations on the city's postwar ranch homes. We understand Lomita's South Bay clay soils, its aging concrete flatwork, and we have served the South Bay since 2020.

Lomita's afternoon sun hits south- and west-facing backyards hard from July through October, making an open concrete patio uncomfortable for hours at a time. A properly installed patio cover - whether solid insulated panels or an aluminum lattice - drops the temperature underneath and gives the backyard real daily usefulness. To see exactly what this type of project involves and what your options are, read more about patio cover installation.
Many of Lomita's single-family homes were built in the 1950s and 1960s with tight floor plans designed for smaller households - and those layouts feel cramped by today's standards. A sunroom addition off the back adds real enclosed square footage without the disruption of a full interior remodel, and on a stucco ranch home with a slab foundation the construction approach is well established and predictable.
Lomita's marine layer rolls in from the coast on many mornings, and when it lifts the afternoon sun takes over quickly. Enclosing an existing patio with glass or insulated panels gives you a sheltered outdoor-adjacent space you can use comfortably in both conditions - protected from the marine drizzle in the morning and shielded from direct sun in the afternoon - without the full cost of a climate-controlled addition.
Most Lomita ranch homes have a concrete patio slab poured decades ago that is now showing the settlement and cracking patterns that come with age on South Bay clay soils. Converting that existing slab into a proper sunroom means working with what is already there - assessing the concrete, addressing any leveling issues, and framing walls and a roof directly from the existing footprint - which is typically faster and less expensive than starting a new addition from scratch.
Lomita's mild South Bay climate - rarely too cold, almost never rainy from May through October - is well suited to a screened outdoor room for most of the year. A screen room on a Lomita ranch home's backyard keeps insects out and provides a sense of enclosure without blocking airflow, making it a practical, lower-cost alternative to a fully glazed enclosure for homeowners who want outdoor living without spending on a complete sunroom build.
Some Lomita homes have older enclosed porches or sunroom-style additions from the 1970s or 1980s that were built without permits or proper insulation. Remodeling that existing structure - replacing single-pane windows, repairing subfloor damage from water infiltration, adding insulation, and upgrading the electrical to current code - is often more cost-effective than demolishing it entirely and rebuilding from the ground up.
Lomita is one of the smallest independent cities in Los Angeles County - just 1.87 square miles - and nearly all of it is single-family residential. The housing stock was built primarily between 1940 and 1970, and at that age the concrete flatwork, original windows, and stucco exteriors on most homes are showing their years. These are the same postwar ranch homes and stucco bungalows you find across the South Bay, and the building conditions - modest lots, aging slabs, stucco finishes that need attention - are familiar territory for our crew. Contractors who are used to working in cities with newer housing stock will encounter patterns on Lomita properties that catch them off guard.
The soil under most Lomita homes is clay-heavy, and that clay expands and contracts with every wet and dry cycle the South Bay goes through. Patio slabs poured in the 1950s and 1960s have been moving with those cycles for decades, and cracking, settlement, and uneven surfaces are common on properties all over the city. When we assess a Lomita property for a patio cover or sunroom addition, we start with the slab - because a structure built on compromised concrete will show movement faster than one built on a stable base. The marine layer from the nearby coast adds another dimension: moisture that works quietly into stucco cracks and wood trim, accelerating the wear you would expect from a home of this age.
Our crew works throughout Lomita regularly, and we understand the local conditions that affect sunroom and patio cover work here. Permits for residential additions in Lomita go through Lomita City Hall, and because Lomita is its own independent municipality - not part of Los Angeles - it runs its own plan check and inspection process. We are familiar with how that process works, and submitting a complete application from the start is how we avoid the back-and-forth delays that slow down projects when a contractor is learning a new city's requirements mid-job.
Lomita sits just a few miles inland from the Port of Los Angeles and San Pedro. The main commercial spine is Western Avenue, and from there the residential streets fan out in a tight grid that puts most of the city within a short drive of one another. The Lomita Railroad Museum sits right in the middle of a residential neighborhood and is the landmark most longtime residents navigate by. Most of Lomita's streets are lined with the one-story ranch homes and bungalows we work on regularly, and the lot sizes - typically under 6,000 square feet - are the kind of compact South Bay lots our crew is used to working within.
We also serve homeowners in nearby Carson and Torrance, so if you know someone in either city who needs sunroom or patio work, we can help them too.
Reach out by phone or through our contact form and we will get back to you within one business day to schedule a visit. We will ask a few basic questions upfront - the size of your patio, what you want to build, and whether you have an HOA - so we arrive prepared.
We come to your home, measure the space, assess the existing slab condition, and walk you through what is realistic given your lot and budget. You will receive a written proposal with itemized costs - no vague estimates - so you know exactly what you are committing to before anything is signed.
Once you approve the proposal, we submit the permit application to Lomita City Hall and order materials in parallel so time is not wasted waiting. Permit review in Lomita typically takes two to four weeks, and we keep you updated throughout.
Our crew handles installation from start to finish and cleans up at the end of each workday. We schedule and manage the city inspection, and when the inspector signs off, your project is complete with a proper permit record attached to your property.
We serve all of Lomita and respond to every inquiry within one business day. No pressure, no commitment - just a straight conversation about what your home needs and what it will cost.
(424) 999-1971Lomita is a small, independent city in the South Bay area of Los Angeles County, covering just under 2 square miles and home to roughly 20,000 residents. It sits between Torrance to the north and west, Carson to the east, and Harbor City to the south. The city is almost entirely residential, built out during the postwar decades with single-story ranch homes and bungalows on modest lots that give the neighborhoods a quiet, established character. Many of the families here have been in Lomita for a generation or more, and the city has a strong reputation as a stable, family-oriented community in an area where housing prices have climbed significantly.
The best-known landmark in Lomita is the Lomita Railroad Museum, a small but well-regarded museum in the middle of a residential neighborhood that displays a restored 1902 steam locomotive and a replica Victorian-era train depot - the kind of thing that gives the city a distinct identity that other South Bay cities do not share. Western Avenue is the main commercial corridor, and from there the residential streets stretch out in the compact grid pattern typical of this part of the South Bay. Homeowners here know their neighbors and tend to take care of their properties. We also serve homeowners nearby in Gardena and Hawthorne if you have neighbors there who could use help with sunroom or patio work.
