Sunroom construction in Whittier CA - a room built level on a sound base
Got a patio, slab or deck you only use half the year? We build a sunroom there that fits how you'll actually use it.
What goes into building a sunroom in Whittier?
Sunroom construction in Whittier means building a room onto your house with walls whose openings are filled with glass or clear plastic, so a patio, slab or deck becomes space you can use more of the year. Depending on the type, the room is either sealed off from the house or open to it, and that one choice shapes most of what follows.
Most people who call me have a patio or deck they only use on nice afternoons, so the first thing I'll ask is how you plan to use the room. The price mostly turns on the room type you pick, its size, the glass that type calls for, whether your slab or deck can carry it and any wiring you want inside. The schedule turns mostly on permit review and on how much base work your site needs, which is why I'd rather sort both out before you sign. If shade is all you're after, a patio cover may do the job with a lot less building. Either way, the visit ends with a written estimate you can read over at home.

Examples of sunroom construction
How we handle sunroom construction, start to finish
I start with the slab or deck and the wall the room will join, because buckles and cracks in an old base can turn into leaks down the road, and the spot where the room meets the house is where a job is won or lost. Then we settle the room type with you and keep the room type, the windows and the base lined up from the first drawing, since changing one later means changing the others. Once the permit is through, our crew does the base work, sets the frame level and square, ties the room into the house and seals that joint, puts in the glass and any wiring you planned, and cleans up before the final inspection.
Some homeowners already have a room out back that leaks or feels dated, and for that we do sunroom remodeling so you aren't paying to start over. If you want fresh air without the bugs and don't need glass at all, screen room installation is a lighter job that still needs the same sound base.
Why Whittier homeowners call Sunscape Whittier Sunrooms & Patios for sunroom construction
I measure and plan it myself
I come out to look at the job, measure and talk it through with you, and I'm on site leading our own small crew once building starts. You deal with the same person from the first walk-through to the last inspection.
Licensed and insured in California
We're licensed and insured, and the Contractors State License Board is the state office that licenses and regulates contractors here. That matters on an addition, because you're letting someone tie a new room into the structure of your house.
Taught to build level and square
I learned under an old-school builder who made me tear out anything that wasn't level and square, and I started this business in Whittier in 2021 on that rule. A room that starts out true is a room where the glass fits and the joints seal.
City or county, permits handled
Addresses around Whittier fall to either the city or unincorporated LA County, and we take care of the permit paperwork for whichever office has yours and meet the inspector at each visit. We'll keep you posted on where things stand, so you're never chasing anyone for an answer.
On a sunroom, the base and the joint at the house wall decide how the room holds up, so that's where I want both of us looking first. Set up a visit and we'll start there.

I come out myself, look at your patio, slab or deck and the wall the room will join, and take measurements. Then I walk you through the room types and what each one means for how you'll use the space.
Read the estimate at home
We put the estimate in writing so you can look it over at home without anyone at your elbow. It lays out the room type, the glass and any base work, so you can see what's driving the price before you decide.
We permit it and build it
We find out which office handles your address, take care of the permit side and meet the inspector, and you'll hear from us as it moves along. Then our own crew builds the room from start to finish, with me on site.
Sunroom construction questions from Whittier
How much does sunroom construction cost in the Los Angeles area?
A sunroom addition in the Los Angeles area usually costs about $23,000 to $66,000 per job, and that's the going range in the area, not a quote from us. Where yours lands comes down mostly to the room type, the size, the glass and whether the slab or deck needs work first. The written estimate from the site visit gives you your own number.
How do I decide if my sunroom should be heated or cooled?
Go heated or cooled if you want the room open to the house and in use every day, and go with a sealed-off, unheated room if it's for mild-weather use. The national sunroom standard treats those as two different rooms, and the heated or cooled one needs glass rated for air leaks, water entry and heat performance, so this choice sets your windows. California's Energy Code also covers additions to existing homes, which is one more reason I pin the room type down before anything gets drawn. If you're torn, I'll usually steer you to the heated or cooled room, because that's the one people end up using.
What is the best way to tell if my patio slab can hold a sunroom?
Have it looked at in person, because one sunroom maker's guide says an existing slab or deck should be in like-new condition and that numerous buckles or cracks make it unsuitable. Cracks matter for more than looks, since they can lead to leaks later on. If yours doesn't pass, the base work goes into the estimate, and photos sent with the form help me know what to look for before I come out.
Do I need a permit to build a sunroom in Whittier?
Yes, Whittier requires a building permit to build, enlarge, alter or convert any building, so adding a sunroom to your house needs one, and most plumbing and electrical work inside it does too. The city's Planning Services looks at the project first, before the plans go to Building & Safety plan review, so planning sits at the front of the schedule. Homes in the Earlham, Hadley-Greenleaf, Central Park or College Hills historic districts also follow their district's own ordinance along with the city-wide historic resources ordinance. Properties in unincorporated LA County get their permit from LA County Public Works instead.
How much can a contractor ask for up front on a sunroom in California?
In California, the down payment on a home improvement job can't be more than $1,000 or 10 percent of the contract price, whichever is less. There's no exception for special-order materials, so a sunroom built from special-order parts falls under the same cap.
Does a sunroom contract in California have to be in writing?
Yes, California requires a written contract for any home improvement project over $500, and any changes to it have to be in writing too. The contract also has to tell you about your right to cancel, so ask about that part before you sign.
Work that goes with sunroom construction
Sunroom remodeling
When an older sunroom leaks, feels dated or no longer fits how you live, a remodel can keep the parts that are still sound.
Screen room installation
When bugs are the real problem and you don't need glass, a screen room opens up the patio with far less building.
