Backyard patios and slabs across Lynwood
Most of our calls come from right here in Lynwood, from homeowners with a back patio, an old wood deck or a bare concrete slab that sits unused most of the year. The lots are fairly compact and a lot of these houses have been added onto over the years, so the space behind the house is often tighter than it looks and already has a cover, a step or an older addition we have to work around. We do the same work next door in South Gate, Compton and Paramount, and the backyards there raise the same questions.
That's why I start every Lynwood job by looking at what's already back there. Whether the slab or deck can carry a room sets much of the price, the schedule turns mostly on whether the job needs drawings and a permit before we start, and I'll put your own figure in a written estimate once I've seen the space.
Our services in Lynwood, CA
A lot of Lynwood backyards already have a concrete slab with an aluminum or wood cover over it, and that's often the easiest place to start a room. We check whether the slab is level and solid enough to carry walls, then tell you plainly whether we can build on it or need a new footing first.
When there's no slab worth keeping, or you want the room tied into the house under one roof, a full sunroom addition is usually the better choice. We build it from the footing up and match the roofline and siding so it looks like part of the house.
Many Lynwood houses run short on space for a growing family, so if you want a den, an office or a playroom you'll use every day, a four season room is the one I'd look at first. We build it with insulated walls and glass so you can heat and cool it like the rest of the house.
Some families just want the patio back without the bugs, and for that a screen room costs less and goes up faster than glass. We frame it so glass panels can go in later if you change your mind.
Plenty of the older patio covers we see around Lynwood are sagging or rotting at the posts, and they're too weak to become part of a room. We replace them with a solid cover that can stand on its own or carry walls later.
We also get calls about older enclosed patios and sunrooms that leak at the roof, fog between the panes or get too hot to sit in. We find what's failing first, then I'll tell you honestly whether fixing that part or rebuilding the room makes more sense.

How it works when you call us in Lynwood
Call or send the form
You call or fill out the form, and we set a time for me to come out to your house. It helps if you're home for that visit, because I want to hear how you plan to use the room.
I measure and listen
I look at the patio, deck or slab, take measurements and talk through which kind of room fits how you live. Then we write up an estimate that spells out what's in it, so you know what you're paying for before you sign anything.
We file, then we build
If the job needs a permit, we prepare the drawings, handle the application with the city and line up the inspections. Then our own crew, led by a lead installer, builds the room while I check in at each stage.
Walk the room together
When it's done, we walk through the room together and I show you how to look after it. That's the time to ask me anything about the glass, the screens or the roof.
Lynwood sunroom questions answered
How do I get a building permit for a sunroom in Lynwood?
You apply through the City of Lynwood's Building and Safety Division, which issues building permits and reviews plans for building, altering or repairing any structure in the city. Its list of permit types names things like water heaters, re-roofs, solar and electrical work but doesn't name sunrooms, so the division is the place to ask about your project. When a job needs a permit, we prepare the drawings and handle the application for you.
What building code does Lynwood check sunroom plans against?
The city checks plans against the California Building Code and the other laws and ordinances that apply, and its inspectors come out to the site to confirm the work meets them. We build to the approved drawings and line up each inspection so the job keeps moving.
Does my sunroom contractor need a California state license?
Yes, the state requires a current license from the Contractors State License Board for anyone who contracts for work that needs a building permit, uses employees, or takes on work worth $1,000 or more in labor and materials combined. The state's exception covers only small jobs under that amount with no permit and no employees, and a sunroom isn't one of those. We're licensed and insured.
When do I need a grading permit for a sunroom in Lynwood?
An undated city submittal document says a separate grading permit is required when the disturbed soil comes to 25 yards or more. A room on an existing slab usually moves far less than that, but new footings or a leveled yard can add up, so we figure the soil we'll move when we draw the plans. The same document says any work in the city right of way, the strip along the street, needs its own encroachment permit.
How do I check if my Lynwood address is in an earthquake hazard zone?
Type your address into EQ Zapp, the California Geological Survey's statewide map, and it shows whether your property lies in any of the state's mapped earthquake hazard zones. If you look it up before I come out, we can go over what it shows at the visit.
How much does a sunroom cost in Lynwood?
There's no honest single number, because the price follows the size of the room, the kind of room and how much of your backyard we can reuse. A screen room on a sound slab sits at the low end, and a four season room with insulated glass, new footings and electrical work sits at the high end. Drawings, permits and any soil work go in too, and your written estimate lists each one.
