What goes into a custom sunroom in Long Beach?
Custom sunrooms in Long Beach are rooms we build onto your existing house, set on a slab or deck, and done well they give you a weather-tight room with a solid connection to the house.
Most people who call us have a patio, a deck or a back wall they barely use, and they want a real room there. The price mostly turns on the size of the room, whether your slab or deck can carry it or a new one has to go in first, and how much work the joint with your house takes. The schedule turns on that same base question plus the permit, and when the job needs one, we pull it and handle the paperwork with the city. I'll give you your own number in a written estimate once I've measured and looked at the base and the wall.
How we build a custom sunroom
On a custom room, the base and the spot where the room meets your wall matter most, so I check the slab or deck before we quote anything. If the base won't hold up, our crew digs out, packs the ground and pours a new slab before any of the room goes up. Then we set the room to the house and put the most care into slope, drainage and the seal at that joint, because one sunroom maker traces most leaks to poor drainage, too little roof slope, weak sealing, sloppy installation or a bad joint with the house. That's also the question I'd ask every company bidding your job, how they handle slope, drainage and the joint at your wall. Our promise on every room is simple. Your satisfaction, guaranteed.
If you're starting from bare ground and want the whole job run start to finish, that's our sunroom construction work. If there's already a room out back that leaks or doesn't fit how you live now, sunroom remodeling is usually the better place to start. Outlets, lights or heating and cooling in the new room need their own electrical and mechanical permits, so we plan those in from the start.
A new slab poured first
This suits a yard with no patio yet or an old slab that won't make a good base. The room is only as good as what it sits on, so starting fresh is often the safer call.
Building on your existing slab
This suits a slab that's still flat and solid, and it can save you the cost of a new pour. I confirm it at the estimate, so you're not finding out halfway through the job.
Building on a deck
This suits a house where the back door sits up off the ground and there's a deck already in good shape. We check the deck as closely as we would a slab before we plan the room on it.
Custom sunroom permits and address checks in Long Beach
Long Beach requires a building permit to build or change a structure, and the city only issues one to a contractor with a valid California State Contractor's License and an active Long Beach business license. Whether a sunroom gets reviewed as a patio or as an addition is the city's call, so we pull the permit and sort that out with them rather than guess. Before design starts, I also ask about your address. If your home is a landmark or sits in a historic district, the city wants a Certificate of Appropriateness before any work begins, even when no building permit is needed, and it treats an addition under 250 square feet as minor work and one over 250 as a major project, so room size matters there. If you're in the coastal zone, construction generally waits on a coastal development permit, and the city notes extra requirements may apply.
On jobs here we run into a lot of older patio slabs that have settled or cracked over the years, and back walls where an old patio cover was fastened on, so I look hard at both before we price anything. We see the same thing on jobs in Lakewood and Signal Hill, and we handle it the same way.
Why Long Beach homeowners call Long Beach Sunrooms & Patios for custom sunrooms
I come to every estimate
I come out to every estimate myself, and I sold sunrooms before I moved over to building them. You get straight answers at the first visit from the person who'll keep checking on your job.
The room we plan gets built
On the sales side I saw rooms sold one way and built another, so I keep the plan simple and make sure our crew builds the room we talked about. You know exactly what you're buying before anyone picks up a tool.
In business since 2021
We've been building rooms onto patios, decks and back walls for five years now. That's five years of learning where these jobs go wrong and planning around it before we start.
Fully licensed and insured
We're fully licensed and insured, and our crew lead and installers are on our team. It's worth asking anyone you compare whether they have employees, because Long Beach then requires proof of workers' comp when the permit is issued.
When you're ready, send us a request or call (562) 200-7450, and I'll come out and take a look.
Request a quoteGet a written estimate for your custom sunroom
We reply within one business day to set up a visit. I come out, measure and look at your slab or deck and the wall the room will join, and the visit is free with no obligation. After that, you get a written estimate.
What happens after you call about a custom sunroom?
Call or send a request
Call (562) 200-7450 or send the form, and we'll set a time for me to come out to your house. Mention where you want the room, so I know what to look at first.
I measure and check the base
I measure, look at the slab or deck and the wall the room will join, and we work through the big choices right there. Then you get a written estimate for the room we talked about, so you know what you'd be paying for before you decide anything.
We handle the permit paperwork
When the job needs a permit, we pull it and handle the paperwork with the city. Patio work can be reviewed over the counter, but an addition needs a full plan submission, so how the city sees your room shapes how long this step runs.
Our crew builds your room
Our crew lead and installers build the room we planned, and I check in on the job as it goes. When it's done, we walk it with you and clean up the site.
Frequently asked questions
How much does a custom sunroom cost in the Long Beach area?
A sunroom addition in the Los Angeles area usually costs about $23,000 to $66,000 per job, and that's a general area estimate, not our price. Where your room lands comes down to what I find at the visit, mainly the size, the base and the wall it joins. Your own figure comes in the written estimate.
Who issues sunroom permits in Long Beach?
Long Beach's Development Permit Center issues building permits for the city. A homeowner of a one- or two-family house may also pull their own permit if they qualify under the city's rules, but on our jobs we pull it and handle the paperwork.
Can I build a sunroom on my old patio slab?
Sometimes, if the slab is in like-new condition, which is what one sunroom maker's guide asks for, and that guide prefers a new slab or deck anyway. A slab with a lot of buckles or cracks won't do, because those can turn into leaks later, so a new slab goes in first. I check yours before we quote.
How much can a contractor ask for up front on a sunroom in California?
California's contractor board caps a down payment at $1,000 or 10 percent of the total contract price, whichever is less. After that, the contract lists each payment and ties it to work done or materials delivered, so you pay as the job moves along. You can read the rules on the Contractors State License Board site.
How do I take care of a sunroom so water keeps draining out?
Check the roof and gutters once a year, keep the door and window tracks clean, and keep the weep holes clear so water can drain, which is what one sunroom company's care guide suggests. The same guide says to use a pure silicone spray on the tracks instead of an oil-based lubricant, since oil tends to pull in dirt.
How do I know I'm hiring the right contractor to enclose my patio in California?
Make sure the contractor's license covers the work, because in California an awning contractor installs awnings and patio covers, and patio enclosures fall outside that license. If someone who mostly builds patio covers offers to close yours in, ask what license they'd be working under.
