Covina backyards ready for a real room
Covina is right next door to West Covina, where we're based, and its neighborhoods feel a lot like ours. Most streets are single-family houses with a backyard, with condos and townhomes mixed in here and there. The calls we get here usually come from homeowners with a patio or deck they hardly use and would like to live in.
It's the same kind of work we do over in Pomona, and it turns on what's already behind the house. An existing slab, cover or deck shapes the room more than anything else, so that's where I start.

Our services in Covina, CA
- Patio enclosures
Plenty of Covina backyards already have a slab and a cover, so enclosing the patio is often the most direct way to a room you'll actually use. We check that the slab and the cover can carry walls and glass before we plan on them, because shade was all they were built for.
- Patio-to-sunroom conversion
When you want more than an enclosure, we turn the patio into a full sunroom with its own roof tied into the house. Older slabs can slope or crack at the edges, so we look at how yours was poured before deciding whether to build on it or add new footings.
- Deck-to-sunroom conversion
A wood deck that's gone soft or loose is a common call, and a room on top asks a lot more of the framing than a barbecue does. I get under the deck to check the posts, footings and beams first, then we rebuild what needs it so the room sits on something solid.
- Custom sunrooms
Houses that have been added onto over the years tend to have rooflines that don't line up, and those are honestly the jobs I like most. We design the room around the roof you actually have, because a stock kit forced onto an odd roofline is where leaks start.
- Sunroom remodeling
Some of the older sunrooms and patio rooms we see have tired seals, foggy glass or a leak where the room meets the house. We open up that joint first, since it's usually the source, then replace panels, glass or roofing as needed.
- Screen room installation
Not everyone needs glass, and a screen room keeps the bugs out and the patio open for a lot less work than a full sunroom. We build it on your existing slab or cover when they're sound, and we can frame it with an eye to glassing it in later.
What Covina houses ask of a new sunroom
A lot of what we see on Covina houses is a concrete patio with an older cover, or a wood deck that's seen better days, and an owner who wants a real room out of it. A slab poured for a patio table wasn't poured for walls and windows, and an older cover was built to throw shade, not to keep a roof dry where it meets the house. So I start at that seam, where the new roof ties into the old one, because that's where small mistakes turn into leaks later. Then I check the slab edge, the deck framing and how water runs away from the house, and I'll tell you plainly if something needs a closer look before I can give you a straight answer.
If your new room adds square feet or changes the roofline, the City of Covina wants Planning approval before the project goes to Building & Safety. That's why we settle the design and the roof tie-in with you before anything gets submitted, so the plan doesn't bounce back.

Covina sunroom questions answered
How do I find out if my Covina address is in the city or the county?
Look it up on the city's address jurisdiction page, because Covina has 11 county pockets inside its borders where Los Angeles County handles planning and building instead of the city. A pocket address can still get Covina Water service, so your water bill won't settle it. In a pocket, LA County Public Works issues the permit, and it's the first thing I check when you send me your address.
Do I need a permit to build a sunroom in Covina?
Plan on it, because the city's Building & Safety Division issues permits for all new construction, and a new room on your house usually counts. The city hands out express permits over the counter for small jobs like a like-for-like re-roof, but says other work will likely need a building plan check, which is where a sunroom usually lands. When your project needs a permit, we take care of the paperwork and inspections with the city or county office that covers your address.
What licenses does a sunroom contractor need to work in Covina?
A contractor needs a California contractor's license from the Contractors State License Board, the state board that licenses and regulates construction here. To pull a Covina building permit, a contractor also shows the license pocket card with its classification, proof of workers' comp insurance, photo ID and a current City of Covina business license, and work in a county pocket needs a Los Angeles County business license. We're licensed and fully insured, so ask me about any of it when I come out.
How much can a contractor ask for as a down payment in California?
The state license board says a down payment is no more than $1,000 or 10 percent of the total contract price, whichever is less. After that, the contract should list each payment, tied to work done or materials delivered, so you're not paying far ahead of the job. The board applies these rules to all home improvement projects, sunrooms included.
How much does a sunroom cost in Covina?
The price comes down to the kind of room, its size and what it sits on, so I give you a number once I've seen your place. A screen room takes far less than an insulated glass room, a sound slab or deck saves work, and an odd roofline, new footings, electrical or a bigger plan review all add to it. Send us your address and what you have in mind, and we'll set up a time to look.
How long does it take to get a sunroom approved and built in Covina?
Much of the wait is on the approval side, and how long it runs depends on whether your address is city or county and how much review your design needs, starting with the Planning step I mentioned above. If you're in a condo and the room touches the building's exterior or common area, the permit also needs a letter of authorization signed by your HOA president, so it's worth starting that early. Once the permit is in hand, the build turns on the room type and what we find where the room meets the house.
