Patio enclosures in Rossmoor CA - a covered patio that works as a real room
Bugs, debris or a cold evening keep you off your covered patio. We close it in so the space works as a room.

What does it take to enclose my covered patio in Rossmoor?
Patio enclosures in Rossmoor, CA close in the covered patio you already have with screen panels, glass or insulated walls, so the space under the cover becomes a room you can actually use.
Most people who call me already have a patio cover they like and a space under it they don't use as much as they'd hoped, because of bugs, leaves blowing in or a draft once the evening cools off. The price comes down to the size of the patio, whether your cover can stay as the roof, whether the slab needs leveling or extending, and what goes in the walls, since a simple screen room costs less than glass or insulated panels. The schedule turns on the same things, plus a permit when your job needs one, because any slab or roof work has to be finished before a wall goes up. I'll give you a figure for your own patio when I come out for the estimate.
How we build a patio enclosure
I start by asking how you want to use the room and writing the answers down, because open air with the bugs kept out and a closed room you can sit in on a cold night call for different walls. Then I look at what's already there, since your current cover and slab set the size of this job. I check whether the roof can stay as it is, and whether the slab is level and reaches far enough to carry the new walls, because a slab that slopes, has cracked or settled, or stops short of the cover's edge usually needs leveling, repair or extending first. Any of those fixes go in the estimate up front, so they don't turn up halfway through the job. Once you've picked screens, glass or insulated panels, our crew does the slab and roof work first, then frames the walls, sets the doors and windows or screens, finishes the trim and cleans up the site.
Some patios aren't a good fit for an enclosure. If your cover has to come off anyway, or you'd rather have a new room built from the slab up, that's sunroom construction, and I'll walk you through the difference. If you want a room shaped around your house and the way you'll use it, instead of walls added under an existing cover, look at our custom sunrooms.

I do every estimate myself
I come out to look at your patio and do the estimate myself, and our own crew does the building while I check the work along the way. The person who wrote down what you asked for is the one making sure you get it.
Planning first, since 2023
I started this business in Rossmoor in 2023 after growing up on my dad's jobs building patio rooms and enclosures, which is where I learned to measure twice and write everything down. Glass and insulation are easiest to get right before anything is built, so I'd rather spend extra time on the plan than fix things later.
Licensed and insured on every job
We're fully licensed and insured. That matters on an enclosure because our crew is working on your slab and against your house, and you shouldn't be the one exposed if something goes wrong.
Permits checked for your address
We find out which office covers your address before anything is drawn up, because homes in Rossmoor and the cities around us don't all go through the same permit office. When the work needs a permit, we take care of the application and meet the inspector.
On an enclosure, what matters most is starting from a cover and slab that can carry it. When you're ready, send us a few details about your patio or call (562) 488-9164, and I'll come take a look.

Patio enclosure styles to consider
Questions before you enclose your patio
What is the best way to choose between a screen room and insulated walls for a patio enclosure?
Pick screens if you mostly want to keep out bugs and debris and still feel a breeze, and pick glass or insulated walls if you want a room that holds back cold, heat and rain. Screens are usually the simpler project, while insulated panels with windows hold temperature better and give you more privacy. If you go with walls, an insulated roof panel upgrade can make the finished room far more comfortable, so I'll bring it up when we talk.
How much does a patio enclosure cost in Rossmoor?
Across the US, a new patio enclosure, screened or with walls and windows, usually costs about $50 to $350 per square foot. That's a national range, not our price, and the wide spread mostly comes from the wall type and whether the cover and slab need work. For a Rossmoor figure, the free on-site estimate prices your actual patio.
Who issues building permits for a patio enclosure in Rossmoor?
Orange County does, because Rossmoor is an unincorporated community and the county issues building permits for private property in its unincorporated areas. The county typically requires permits for residential improvements such as patios and decks, and its permitting service answers questions at (714) 667-8888 or OCPWPermitting@ocpw.ocgov.com. The county's forms list also has handouts on typical lattice and roofed patio covers if you want to read up on the cover you have, and we handle the application when your job needs one.
Can my lattice patio cover become the roof of an enclosed patio?
Usually not as it is. One seller's guide says lattice and open-slat covers can't serve as the roof of an enclosed room unless they're replaced or topped with solid panels, while a solid aluminum cover in good condition is a much better starting point. That's why the cover you have shapes the scope of the job, and why it's the first thing I look at.
What license does a contractor need to enclose a patio in California?
California's contractor licensing board says a C-27 contractor may contract and pull permits for non-watertight patio covers and outdoor decks. That guidance speaks to open covers, not walled rooms, so ask any contractor you're comparing which license they hold for a walled enclosure.
How do I take care of a patio enclosure after it's built?
Keep the door and window tracks clean, and keep the weep holes clear so water can drain out of the frame. One maker's care guide also says to use a pure silicone spray on the tracks rather than an oil-based lubricant.
