Homes and backyards across Placentia
Placentia is mostly single-family neighborhoods, and most of the backyards we walk into already have something to work with, like a concrete patio, an older patio cover or a low wood deck. The calls we get here usually come from people who like that space but can't use it the way they want. We're based in Placentia and do the same work next door in Fullerton and Yorba Linda, but a lot of our time is spent right here in town.
What's already out back shapes the job more than anything else. A slab poured for patio chairs or a deck built close to the ground wasn't always meant to carry walls and a roof, and on older houses the joint where the new room meets the wall and roof takes careful work to keep it dry.
Our services in Placentia, CA
Plenty of Placentia homes have yard to spare but no room left inside, so a sunroom addition adds a real room tied into your walls and roof. We plan the footing and the roof joint first, because those are what keep the room solid and dry.
A lot of patios here are slabs poured years ago for a table and a grill, not for walls and a roof. We check the slab for cracks, thickness and drainage before enclosing it, and add footings where it can't carry the room on its own.
Some decks around town are sound, and some have posts and joists that were never sized to hold a roof. We open up the framing to see what's really there, then reinforce or rebuild the base before the room goes on.
If you want to sit in the room on a summer afternoon and a winter evening, it needs insulated walls, better glass and usually heating and cooling. I go over that against a three-season room at the start, because it's the choice that changes the build the most.
Sometimes shade is all a backyard needs, and a patio cover gives you that without walls or glass. We attach it so water runs away from your house, and if you think you'll want walls someday, we can plan for that now.
Older sunrooms and patio enclosures around here often leak where they meet the house or get too hot to use. We track down where the water or heat is getting in and fix the roof joint, glass or panels instead of covering the problem up.

How it works when you call us in Placentia
Call or send the form
You call (657) 226-2045 or fill out the form, and we get back to you to set up a visit. It helps if you're home for it so we can talk about how you want to use the room.
I look at the spot
I come out myself, look at the slab, deck or yard and where the room would meet your house, and ask how you plan to use it. After that you get the plan and the estimate in writing.
We handle the permit paperwork
We pull the permit and bring in drawings from a licensed architect or engineer when the city asks for them, and the city reviews the plans once planning and zoning clearance is done. If you're in an HOA, tell us early so their sign-off doesn't hold up the start.
We build and walk through
Our own crew does the build, I run it, and we meet the city inspector on site. When it's finished, I walk through the room with you.
Placentia sunroom questions answered
Do I need a permit to add a sunroom in Placentia?
A sunroom built onto your house is a room addition, and the City of Placentia lists room additions among the projects that need plans submitted for review. The city's Building Division reviews those plans after planning and zoning clearance is in place. We take care of that paperwork as part of the job.
Does a sunroom contractor need a license in California?
Yes, anyone who contracts for work that needs a building permit must hold a current license from the Contractors State License Board, and so does anyone using employees or taking on work of $1,000 or more in labor and materials combined. Placentia also requires an annual city business license, and its number is needed to pull a building permit. We're licensed and insured, and you can check any contractor with the board before you hire.
How much does a sunroom cost in Placentia?
The price turns mostly on the type of room and what it sits on. A four-season room with insulated walls, better glass and heating and cooling costs more than a three-season room, and a slab or deck that needs new footings or reinforcing adds to it, as do size, how the roof ties into your house and any drawings the city asks for. The schedule turns mostly on the city's plan review and on what we find once an old slab or deck is opened up, and I put your own numbers in writing after the visit.
How do I turn my patio into a sunroom in Placentia?
Start by finding out whether your patio slab can carry walls and a roof, because a slab poured for outdoor furniture wasn't always built to hold a room. I look at its condition, how it drains and where the room would join the house, though some things only show once we open it up. From there it's drawn and permitted like any room addition before we build.
Which building code applies to sunroom plans in Placentia right now?
Plans going into review now have to meet the 2025 California building codes, which apply to plans the city accepted for review on or after January 1, 2026. If you had sunroom plans drawn up before then, have them checked against the current codes before they're submitted, and I'm glad to go over them at the estimate.
What causes a sunroom to leak where it meets the house?
Most leaks start at the joint where the sunroom roof ties into the house, when the flashing that turns water away from that seam isn't lapped and sealed right. That joint and what the room sits on are the two things I watch closest on every build, because they're what you'd be living with if they were done wrong.
