Sunroom additions
A room built onto the back of the house with its own roof tied into yours, a good fit for Laguna Niguel homes where the patio gets too much sun to use.
Apex Mission Viejo Sunrooms and Patios is a sunroom contractor building sunrooms, patio enclosures, screen rooms and patio covers for Laguna Niguel homes, turning patios and decks you hardly use into rooms you'll sit in every week.

Laguna Niguel is a short drive from our base in Mission Viejo, and the backyards here are hard on a room. Summers bring long hot, dry stretches, and Santa Ana winds can reach 70 mph or more, so glass that cuts the heat and a roof tied down hard to the house matter more here than extra square footage. Plenty of yards step down a slope, too, so we build on raised decks about as often as slabs, much like we do in Aliso Viejo and Laguna Hills.
What moves the price is the room type, from a screen room up to a four season room with insulated glass and its own heating and cooling, then the size, how the roof ties into the house, any power you want and what the slab or deck needs first. The schedule mostly turns on city plan check and your HOA's review, covered in the questions below, and your written estimate puts a figure on your room.
If your house was built after 1989, ask the city's Building Division for its original plans, because the city may have copies, and they show us how the back wall was framed before we tie a room into it.
Since 2013 I've come out to size up every yard myself, and our own crew does the build, so the person who told you what fits is the one answering for it.
A sunroom is only as good as the slab or deck it sits on, so if yours needs work I'll tell you up front, not after the walls go up.
I'd rather build the room you'll sit in every week than the biggest one we could sell you, so we start from how you plan to use it.
A room built onto the back of the house with its own roof tied into yours, a good fit for Laguna Niguel homes where the patio gets too much sun to use.
Insulated walls, glass and a heated and cooled space you can use through hot dry summers and cooler winter nights, framed and finished like a real room of the house.
Glass walls without full insulation or heating and cooling, a lighter and less costly room that works most of the year here and keeps wind and dust off your furniture.
We close in an existing covered patio with glass or screen panels, which usually costs less than a new room, once we confirm the cover and slab can carry it.
Rooms shaped to an odd corner, a sloped yard or a view down the hill, with the roof line, glass layout and doors drawn around your house instead of a catalog.
Our own crew handles the build from footings or base prep through framing, glass, roof and trim, so one team answers for how the whole room comes together.
Older sunrooms tend to run hot or leak at the roof. We replace tired glass, roof panels and seals, or rework the room so you'll want to use it again.
A screened room keeps bugs and leaves out while letting the evening breeze through, a lower-cost choice when you mostly want shade and fresh air on the patio.
Most calls we get start with a slab out back that nobody uses. We check its thickness and condition first, then build a room on it you'll sit in.
Raised decks on sloped lots usually weren't built to carry walls and a roof, so we look over the posts, beams and footings and reinforce them before we build.
An insulated room with the glass, heating and cooling to stay comfortable on the hottest afternoons, worth it if you want a family room or office, not just a porch.
We wall in a patio with short solid walls, windows and doors, giving you a sheltered room off the kitchen without the full cost of an addition.
A glass-roofed room for the most light, good for plants or a view, though on hot Laguna Niguel afternoons we'll talk you through tinted glass and shading first.
A solid or lattice cover puts shade over the slab you already have, and we anchor it firmly to the house and posts so it holds up on windy days.
On the first visit I'll tell you what kind of room makes sense for your yard, then we draw the plans the city reviews before anything gets built.
Vinyl frames don't rust or need paint and hold up well in dry heat, a practical, lower-upkeep pick for a three or four season room on your house.
Send the form and we'll reply within one business day to set up a visit. I come out, measure and look over your slab or deck, then we send a written estimate, free and with no obligation.
I measure your space in person instead of pricing off photos, because the slope, the base and where the roof meets the house all change what the room takes.
You get the estimate in writing, so you can look it over at home, line it up against others and ask us about anything before you decide.
If the city or your HOA needs a signature, an approval or anything else from you, we tell you early so it doesn't hold up the start.
Here's what Laguna Niguel homeowners usually ask us about permits, plan review, licensing and fire zones before adding a sunroom.
Yes, a sunroom built onto your house is an addition, and the city's Building & Safety Division issues permits for additions and remodels. The city reviews the plans for structure, earthquake safety and fire protection before work starts, and inspectors visit during the build to check it against those plans. We file the permit and book the inspections for you.
The city says plan check takes 10 business days on a first submittal and 5 business days on a resubmittal. Before the city can issue the permit, your HOA and agencies such as Moulton Niguel Water District or the Orange County Fire Authority may need to review the plans, so we get those moving early.
Yes, the Contractors State License Board requires a license when a job needs a building permit, uses any additional workers or totals $1,000 or more in labor and materials, with a few exemptions the board lists. A sunroom clears that bar easily, so ask any contractor you're considering for theirs. We're licensed and insured.
No, the city says there's no business license needed in Laguna Niguel. That puts the weight on the state contractor license and the building permit, so those are the two things worth checking before you hire anyone to build a sunroom on your house.
It can. CAL FIRE's map rates parts of Laguna Niguel Very High, High or Moderate, the city requires defensible space, a cleared area around buildings, on properties in those zones, and it says new buildings there are to use fire-resistive features. We look at how that applies to your lot when we plan the room and pick materials.
We're based in Mission Viejo and work across the Orange County cities around it. These are the ones with their own page, so if yours isn't listed, call or send the form and ask.
Call (949) 619-8191 or send the form now, since the HOA and city reviews come before any building and the clock starts when we file.
