Sunroom additions in West Covina, CA - a bright room that ties into your house
Your patio sits empty most of the year because it's too hot, too buggy or too exposed. We build a room there you'll use.
What goes into adding a sunroom to a West Covina house?
A sunroom addition in West Covina is a new room built onto your house. It can be a bright, simple room with no heating or cooling, or one that works like any other room in your home. Either way, you get a spot for morning coffee, plants or the kids that's out of the wind and bugs and still full of light.
Most people who call me have a patio or deck they'd use a lot more if it had walls and a roof, and if yours is already a covered slab, our patio-to-sunroom conversion work starts from what's there. The price mostly moves with the size of the room, whether it's heated or cooled and opens to the house, what it sits on, and how tricky your roofline is to tie into. The schedule usually turns on the city's plan review and on any checks your deck or patio needs first, and you'll get a figure for your own room from an on-site estimate.
How we build a sunroom addition
The first thing I want to know is how you'll use the room and whether it opens to the house, so that's where we start, and we work out where it sits in your yard before anyone draws a line. Then I look hard at where it meets your house, the wall, the eaves and the roofline, because an odd roof or an older patio changes how we tie in, and I'd rather go find out what's under the stucco than guess. Once the plan's set and any permit is in hand, our crew gets the base ready, frames the room, ties the new roof into your house and flashes that joint so water runs off it, then sets the glass and doors, seals everything up and cleans up after ourselves.
The biggest choice after that is how much of the year you want to use it. A four season sunroom is heated and cooled so it works in August and January alike, while a three season sunroom skips the heating and cooling for a lighter build you'll use from spring into fall.
Why West Covina homeowners call West Covina Sunrooms & Patios for sunroom additions
The owner looks at your job
I'm the one who comes out to look at your yard, and our small crew does the build with me on site. So the person who planned how the room ties in is standing there when it gets built.
Careful where it meets your house
Since I started this business in 2023, the jobs I like best are odd rooflines, older patios and tired decks, and the joint between your house and the new room gets more of my time than anything else. That's where small mistakes turn into big ones, and if I can't tell what's in there until we open it up, I'll tell you so.
Sized for West Covina's yard rules
We're based in West Covina and work in the cities around it, and here the city wants 60 percent of the required rear yard kept open, with limits on floor area and building coverage for additions in single-family zones. We check your lot against those before we pick a size, so we're not sketching a room the city won't allow.
Licensed and fully insured, easy to check
We're licensed and fully insured. Before you sign with anyone, you can check a contractor's license status with the Contractors State License Board online or by calling 1-800-321-CSLB.

A look at sunroom additions
Questions before you book a sunroom addition
How do I decide between a heated sunroom and an unheated one?
Start with whether you want the room open to the rest of your house, because a room that opens to your home is essentially a regular room addition, while the simpler sunroom types have no heating or cooling at all. There's a middle option too, a room with its own heating or cooling where your existing doors and windows stay in place to keep it sealed off from the house. State energy guidance treats adding heating or cooling to a space that had none as an addition, so we settle this early, since it decides which energy rules your project falls under.
Can a sunroom go on my existing deck in West Covina?
Usually yes, but the deck will typically need added beams, posts or footings to carry the weight of a room. A local structural engineer can tell you whether your deck is up to it, so we get that answer before we design anything, and our deck-to-sunroom conversion page covers that job in more detail.
How much does a sunroom addition cost near West Covina?
A sunroom addition in the Los Angeles area usually costs about $25,000 to $65,000 for the whole job. Where yours lands depends mostly on the size, whether it's heated or cooled, and what it sits on, and your own figure comes from the estimate after I've seen the spot.
Who reviews sunroom plans in West Covina?
The city's Building Division handles plan review, permits and inspections for private projects in West Covina, and it takes applications and plans through its online permit portal rather than by email. When your project needs a permit, we take care of the paperwork and inspections with the city or county office that covers your address, so you're not uploading plans yourself.
How much can a contractor ask for up front on a sunroom in California?
Under the state licensing board's rules, a home improvement down payment should stay within 10 percent of the contract price or $1,000, whichever is less. Any home improvement job over $500 in combined labor and materials also needs a written contract, so have one in hand before work starts.
How do I take care of sunroom doors and windows?
Keep the door and window tracks clean, and one maker's guide says to use pure silicone spray on them instead of an oil-based lubricant. The same guide says to keep the weep holes, the small drain openings, clear so water can get out.
Other sunroom work to consider
- Four season sunrooms
If you want the room comfortable on the hottest and coldest days and open to the rest of the house, this is the one to look at.
- Three season sunrooms
For a lighter, unheated room you'll use from spring into fall, this keeps the build and the budget simpler.
