About Seal Beach, CA
Seal Beach is our home city, and a lot of different houses fit into this short stretch of coast. Near the water you see older cottages and rebuilt two-story homes on narrow lots, close to the neighbors on both sides. Further from the beach the streets run more to single-story stucco houses with a concrete patio out back that's been there as long as the house. It has a lot in common with Long Beach on one side and Huntington Beach on the other, but the lots here tend to feel tighter.
On a tight lot the new room often takes up most of the backyard. That's why where it meets the house, where its roof sends the water and how much light it takes from the rooms behind it matter more here than the style of the windows.
Services in Seal Beach, CA
Sunroom additions
Plenty of Seal Beach houses have a back room or patio that's already doing more than it was built for, and a sunroom addition turns that spot into a real room. We tie the new roof and walls into your house the way any addition should be, because that joint is where leaks usually start.
Patio enclosures
Most patios we see here are an older concrete slab with a cover over it that gets used a few months a year. We check that slab before we enclose it, so the new walls sit on something that won't crack or settle under them.
Patio cover installation
When the yard is small, a patio cover is sometimes a better answer than a full room, because it keeps the space open and the house behind it bright. We fasten it to the house so it carries its load properly and sends rainwater away from your wall and your neighbor's.
Four season sunrooms
If you want a room you'll use every evening of the year, a four season sunroom is insulated, heated and built like the rest of the house. It costs more than an unheated room, so I'll walk you through that choice before you sign, and then the decision is really yours.
Three season sunrooms
A three season sunroom is the unheated version, glass and screens on a lighter frame, and a lot of owners here pick it for a reading spot or a place to eat outside. It's easier on the budget, and I'll tell you up front what it would take to heat it later if you change your mind.
Deck-to-sunroom conversion
Raised decks off a back door are common on the two-story houses near the water, and owners often want to close them in. A deck built for chairs and a grill usually isn't framed to carry walls and a roof, so we open it up and check the framing and footings first.
Working in Seal Beach: permits, licenses and what moves the price
In Seal Beach, building permits go through the Building Official in the city's Community Development Department, and that office also approves the inspections along the way, so a sunroom usually moves forward one approved inspection at a time. Under the city's proposed building code, a permit lapses if work doesn't start within a year of being issued, or if a year goes by without an approved inspection, so I don't pull one until we're ready to build. Before you hire anyone, ask to see their California contractor license. We're fully licensed and insured, and we find out what the city and any coastal review will ask for, pull the permits and set up the inspections, so you're not chasing paperwork.
The price here mostly comes down to the size of the room, whether it's heated, how much glass you want, and what the slab and the house wall need before we build on them. The schedule depends more on permits and any coastal review than on the build itself. I'll lay out your options in a written estimate after I've seen the space. We do the same work in nearby cities like Westminster and Cypress, and in others around Seal Beach.
Seal Beach, CA properties and local conditions
A lot of houses here have stucco walls, and many have had a few rounds of patching over the years. Adding a room means cutting into that stucco carefully, flashing the joint so water runs out instead of in, and patching it back to match. You won't see that work once the room is finished, and it's where I spend the most time, because a sloppy tie-in is usually what leaks years later.
Lots near the water are tight, with neighbors close on both sides, so we plan the roof drainage, the height and the side walls before we start, and we keep the shared fence and the side yard clear while we work.

What happens after you call us in Seal Beach
Call or send the form
Tell us a little about the house and the patio or deck, and we'll find a time for me to come out. It helps if you're home for that visit, since you're the one who'll be using the room.
I come out and sketch
I look at the house, the patio or deck and how you want to use the room, and I sketch the options with you right there. You get a written estimate before anything is signed, so you know the number before you decide.
We handle permits and build
We pull the permits the job calls for and set up the city's inspections, and my crew and I build the room together. I'm on site working, not just stopping by to check.
Walk the finished room
When it's done, I walk through the room with you and show you how to look after the windows, screens and seals. Your satisfaction, guaranteed.
Frequently asked questions
Does my deck or patio cover need a permit in Seal Beach?
Under the city's proposed building code, a deck needs no building permit if it's 30 inches or less above the ground, isn't built over a basement or a story below, and isn't part of an accessible route. A detached one-story shade structure needs none up to 120 square feet and 12 feet tall, but a cover attached to your house or a room built on a deck isn't on that list. Skipping a permit doesn't make work that breaks the code acceptable, so we check what your project needs before we build.
When does a contractor need a state license in California?
Under the Contractors State License Board's rules, a contractor needs a license when labor and materials on one or more contracts add up to $1,000 or more, when the job needs a building permit, or when they bring on other workers. Splitting a bigger job into pieces under $1,000 doesn't get around that rule. We're fully licensed and insured, and you should ask to see any contractor's license before you sign.
How much of a down payment can a contractor ask for in California?
The state licensing board's guidance says a contractor can't ask for or accept a down payment of more than $1,000 or 10 percent of the total contract price, whichever is less. The board says that applies to all home improvement projects. If someone wants more than that up front, ask why before you sign anything.
How do I check if my Seal Beach home is in a tsunami hazard area?
You can type your address into the California Geological Survey's Tsunami Hazard Area map for Orange County, which the Seal Beach Police Department shared with residents. It shows whether your property falls inside the hazard area and is meant for evacuation planning, so it's worth a look whether or not you're adding a room.
How much does a sunroom cost in Seal Beach?
The cost of a sunroom in Seal Beach mostly comes down to its size, whether it's heated, how much glass it has, and what the slab and the house wall need before we build on them. An unheated room on a solid patio slab costs less, and a heated room that needs new footings and electrical work costs more. I'll give you a written estimate once I've seen your space.
What is the best way to turn a patio into a sunroom in Seal Beach?
Start with the slab and the wall the room will tie into, because those decide what you can build before style even comes up. We check whether the patio slab can carry walls and a roof, decide with you whether the room will be heated or unheated, then flash and seal the joint to the house so water stays out. After that, picking windows and finishes is the easy part.
