Back Patios
PATIO TO ROOM CONVERSION
Convert Your Back Patio Into a Real Room — Without a Real Addition Price Tag
Most Orange, CA homes already have the foundation of an additional room — it's the slab under your back patio. Enclosing that patio converts unused outdoor square footage into a finished, permitted indoor room: a breakfast room, home office, playroom, or sunroom. Done right, a backyard patio conversion adds the room your house has been missing for 50-70% less than a traditional stick-built addition, and the work wraps up in months instead of construction seasons.
We've been enclosing back patios in Orange for more than 30 years — from craftsman bungalows in Old Towne where the back patio sits under a deep roof overhang, to estate lots in Orange Park Acres where the patio runs the length of the house. Every project starts with a free in-home visit to evaluate your existing slab, footings, and cover (if you have one), then we talk through what kind of patio enclosure fits your house, neighborhood, and budget.

WAYS TO ENCLOSE YOUR PATIO
How to Convert a Back Patio Into a Room in Orange, CA
Five different patio conversion paths, depending on what your existing patio looks like and how you want to use the new room. Need help picking? Book a free in-home visit.
Enclose with Glass
Floor-to-ceiling glass walls turn your covered back patio into a fully enclosed, weatherproof room with full visibility to the yard. The most popular patio conversion in Orange.
Enclose with Screen
DuraScreen enclosure panels convert an open or covered back patio into a screened back porch — full breeze, zero bugs, lower cost than glass.
Enclose with Aluminum & Windows
Aluminum-frame walls with operable windows let you open or close the patio room as the weather changes — the most flexible back patio conversion.
Cover Then Enclose
No existing cover? We install an engineered Duralum patio cover first, then enclose under it. One contractor, one permit, one project.
Insulated Patio-to-Room Conversion
Insulated EPS roof panels paired with C-Thru wall systems turn a basic patio into a finished, climate-controlled room you can use 12 months a year.
Patio Refresh & Re-Enclose
Have a tired old enclosure already? We can strip it back, replace the glass and screens, and re-finish it as a modern patio room — without starting from zero.
WHY ENCLOSE YOUR BACK PATIO
Why Convert a Back Patio Instead of Building an Addition
Most Orange homeowners considering a back patio conversion are weighing it against a traditional room addition. Here's the math.
Use the Slab You Already Have
A traditional room addition starts with excavating, pouring a new foundation, and tying it to your existing structure. A patio conversion uses your existing slab, footings, and (often) cover — eliminating tens of thousands of dollars and weeks of work.
50-70% Less Than an Addition
Enclosing a back patio in Orange typically runs $15,000-$45,000+ depending on style and size. A comparable stick-built addition runs two to three times that. Same usable square footage, fraction of the cost.
Months, Not Construction Seasons
A back patio conversion finishes in a few months total — most of it permitting. A traditional addition can run six months to a year with your house torn open. With us, the on-site disruption is days to a few weeks.
Permitted, Warrantied, Real
A properly converted back patio is a permitted living-space addition, not a handyman project. It appears on title, it adds resale value, and it carries a transferable lifetime manufacturer warranty.
