Deck-to-sunroom conversion in Whittier CA - a room on a deck that can carry it
You've got a deck you only use a few months a year. We check what's under it, then turn it into a room you'll use.
Can I turn my deck into a sunroom in Whittier?
Often, yes. A deck-to-sunroom conversion in Whittier adds walls, windows and a roof to the deck you already have, so it becomes a room you can use through more of the year, as long as the deck underneath can carry the extra weight.
Most people who call about this like their deck but hardly use it, because the afternoon sun, the wind or the bugs chase them back inside. The price mostly comes down to the shape the deck is in, whether it's raised or close to the ground, how big the room is, and whether you plan to heat and cool it or just close it in. The schedule mostly depends on whether the deck needs work first and how long the permit takes with your city or county. We take care of the permit paperwork and meet the inspector, so that part isn't on you. I'll give you your own figure in a written estimate once I've seen the deck.

What deck-to-sunroom conversions look like
How we handle a deck-to-sunroom conversion
A deck built for open air wasn't made to hold walls and a roof, so before we plan anything I check the footings, the framing, how much weight it can take and where the water goes when it rains. If it needs beefing up, I'll tell you plainly and show you why, because the parts nobody sees, like what's under the room and the spot where it meets your house, are where this job is won or lost. Parts of Whittier sit in a very high fire hazard zone, and the State Fire Marshal's office sends owners to their city or county for the map of a specific address, so I check where yours falls before we plan the room. Once the deck is sound, our crew reinforces what needs it, frames the walls, sets the windows, ties the roof into the house so it sheds water, and cleans up when we're done. Does that order make sense? We fix the base first because everything after it depends on it.
Some people find out during the visit that they want something a little different. If you want to heat and cool the space and use it every month of the year, we'll talk through all season rooms, which are planned around that from the start. If you mostly want shelter from wind, sun and bugs without making it full living space, enclosed patio rooms can be the simpler way to get there.
Why Whittier homeowners call us to close in a deck
I measure your deck myself
I come out myself to look at the deck, measure it and talk it through with you, and I'm on site leading our own small crew when we build. You're not explaining your job to one person and then watching strangers build it.
Trained to build level and square
I learned under an old-school builder who made me tear out and redo anything that wasn't level and square, and I started this business in Whittier in 2021. That habit matters on a deck, because the room can only be as true as what it sits on.
Licensed and insured on this work
We're licensed and insured. A conversion ties into the structure of your house and gets inspected along the way, so you want the people doing it properly covered.
City address or county, checked early
We're based in Whittier and work city addresses and the unincorporated county areas around it, and those don't all go through the same office. We check your address early so we know who's handling it, and we keep you posted on where things stand.
On a deck job, it all starts with what's under the room, so start by showing me the deck. Send your address, a few photos, whether it's ground-level or raised, and about how old it is through our contact form, or call (562) 203-1022.
Get a written estimate for your deck conversion
Send the form and we'll reply within one business day to set up a visit. I come out myself, the on-site estimate is free and in writing, and there's no pressure to book.

What happens when you call about a deck conversion in Whittier?
Call or send the form
You reach us by phone or the form, and we get back to you to set up a time to come out. If you can, tell us whether the deck is raised and roughly how old it is.
I walk the deck with you
I look at the deck and the wall the room will join, then walk you through the room types and what each one means for how you'll use the space. Ask anything you want here, because this is where the choices get made.
You get it in writing
We put the estimate in writing so you can look it over at home without anyone standing over you. If the deck needs work first, it's spelled out there before you decide anything.
Permit, inspections, then the build
We find out which office handles your address and take care of the permit, and in Whittier you get a Job Card when the permit is issued and the job usually has several inspections along the way. Our own crew builds the room from start to finish, with me on site leading the work.
Deck-to-sunroom questions in Whittier
How do I know if my deck can hold a sunroom?
You find out by having what's under it looked at before anything gets planned. Ground-level patios often make a stronger starting point because of their solid base, while raised decks may need added structural work, and how much depends on the deck's age and how it was first built. One sunroom maker's installer training says the room has to sit on a deck that's level, square and built to code, which is why I never skip that look.
How much does a deck-to-sunroom conversion cost around Los Angeles?
A fully insulated, year-round sunroom in the Los Angeles area usually costs about $19,000 to $79,000 per project. That's the going rate for a finished room you can use in every season, not our price. Where yours lands depends a lot on what the deck needs before the room goes on, and I'll show you that in the written estimate.
Do I need a permit to turn my deck into a sunroom in Whittier?
Yes, Whittier requires building permits to build, enlarge, alter, improve or convert a building, and closing in a deck falls under that. In the city, a project goes to the city's planning staff first, then the plans go to Building & Safety for review. If your home is in unincorporated LA County, LA County Public Works issues the permit instead of the city.
Can I apply for the sunroom permit myself in Whittier?
Yes, Whittier issues permits to owners of residential property as well as to licensed contractors, and an owner can also name an agent with a notarized letter. If you go that way, you can call the city at (562) 567-9320 and ask for a Planner. If you hire someone, ask for their state license number, since the city's permit form adds a contractor by that number and you can look it up on the California State License Board website.
Does a heated and cooled sunroom count as an addition in California?
Yes, the state's energy guidance counts heating and cooling a space that wasn't heated or cooled before as an addition, and it uses a conditioned sunroom as its example. So if you plan to run heat or air conditioning out there, the room should be planned as an addition from the start. Tell me at the visit how you'll use it, so we plan it the right way the first time.
How do I take care of a sunroom after it's built?
Have the roof and gutters looked over once a year, which is what one sunroom company's guide suggests. Those are the places water finds its way in first, so a yearly look catches small problems before they get bigger.
