What is a solarium, and is it the right room for your house?

Solarium installation in Fountain Valley means building a fully enclosed room onto your house, with all-weather windows and its own heating and cooling, so you have a room you can sit in comfortably in all four seasons and not just on mild days.

Most people who ask me about a solarium have a patio or an older enclosure they only use when the weather is kind. The first choice is the room type, because a three-season room or enclosed patio is generally not heated or cooled and has screens or uninsulated windows, so it suits seasonal use, while a solarium is the room you pick when you want comfort all year. The price moves with the size of the room, whether your slab is sound or needs repair or a new foundation, the heating and air conditioning, and how much insulation goes into the windows, walls, floor and roof. I'd ask you to settle that insulation before we begin, since one cost guide notes it goes in far more easily during the build and adding it later can often cost more. The schedule mostly turns on the city's plan review and on any slab repair we find, and the written estimate I send spells out each of these choices for your room.

How do you know your patio is ready to become a solarium?

  • Patio sits empty most months

    You walk past the patio more often than you sit on it, because it's too chilly in the evening, too bright at midday or full of bugs. That usually means the space needs walls, glass and climate control to earn its keep, and every season you wait is another one you don't use it.

  • Sunroom too hot or too cold

    An older enclosure that bakes in summer and chills in winter is usually a seasonal room with no heating or cooling and uninsulated glass. Waiting won't change that, and it leaves you keeping up a room you rarely open the door to.

  • Puddles or buckling at the slab

    Water standing along the edge of the patio after rain or sprinklers, or concrete that has heaved up, tells me the base needs attention before anything is built on it. It's far easier to fix a slab while it's open to the sky than after a glass room sits on top of it.

  • Patio cover installation

    If part of the yard should stay open to the air, a solid cover beside the solarium gives you shade for the grill or the table without closing it in.

  • Sunroom design

    Working out the room's size, glass, roof and doors on paper first keeps you from paying for more room than you'll actually use.

How we handle solarium installation

On a solarium job I start underneath. I check that the slab sits above the yard and sheds water away from the room, and we repair real damage before any glass goes up rather than after, because a room is only as sound as what it stands on. Once the base is right, our crew frames the room and ties it to your house, puts in the insulated walls, roof and floor you chose, sets the all-weather windows and doors, and brings heating and cooling into the room before we finish the trim and clean up the site.

Some yards need more than the room itself. If you'd like covered outdoor space next to the solarium, we can take on patio cover installation as part of the same project, and if you're still deciding on size and layout, our sunroom design work settles those questions before anything is ordered.

  • Solarium on your existing slab

    This suits a patio slab that sits above the yard and is free of real damage, because building on what you already have usually keeps the cost down. We repair what needs it first, then build.

  • Solarium on a new foundation

    This suits a bare yard, or a slab too low or too damaged to be worth saving. It costs more, but it gives a larger room a base made for it from the start.

Why Fountain Valley homeowners call Fountain Valley Sunrooms & Patios for a solarium

  • The owner measures and builds

    I come out to measure and look over every job myself, and I work on site alongside our crew through the build. Any question you have during the work goes to the person who wrote your estimate.

  • Your lot checked against city limits

    In Fountain Valley, a single story, attached addition can come within 10 feet of the rear property line only if it's no wider than half the lot, and the rear yard has to keep 1,000 square feet of open space. Buildings can also cover no more than 60% of the lot, or 50% on lots of 10,000 square feet or more, so I check your lot against both before we settle on a size.

  • Fully licensed and insured

    We're fully licensed and insured. Please feel free to ask for proof before you sign, as you should with anyone building onto your house.

  • Honest advice on room size

    I started this business in Fountain Valley in 2023 after years on sunroom and patio jobs, and I'd rather build the room you'll use than the biggest one you can afford. If a seasonal enclosure fits the way you live, I'll tell you so.

A solarium is only as good as what it stands on, so that's where I'll look first. Please request your visit or call (657) 329-2023, and thank you for considering us.

What happens after you call about a solarium in Fountain Valley?

  1. Call or send a message

    Call (657) 329-2023 or use the form, and we'll set up a time for me to visit. We take calls weekdays from 8 AM to 10 PM and weekends from 6 AM to 9 PM.

  2. I measure and check the base

    I measure, look at the slab or deck the room will stand on and ask how you plan to use the room. You then get a written estimate in plain words covering the room size, any slab repair, the insulation and the heating and cooling, so you know exactly what's included.

  3. We file the permit paperwork

    If you go ahead, we prepare the plans and upload them to the city's Permit Center online for plan review, sending paper plans separately when the Fire Department needs to review them. We'll tell you early if we need anything from you, such as HOA approval.

  4. We build and walk it together

    I'm on site with our crew through the build, and we meet the city inspector when the work calls for it. When the room is finished, we walk through it with you before we leave.

Common questions

  • How much does a solarium cost in the Fountain Valley area?

    A sunroom in Orange County usually costs about $20,000 to $120,000 per project, and that's the area's going range rather than our price. Larger rooms that need a foundation and heating and air conditioning land toward the top of it. Your written estimate gives the figure for your own room.

  • Do I need a permit for a solarium in Fountain Valley?

    Most likely, so plan for one and check with the city's Building Division if you'd like to be sure. Fountain Valley's building official issues permits to build, enlarge or alter any structure, and the city's list of work that doesn't need a permit names sheds and awnings but not solariums. When your room needs one, the filing is part of our job.

  • How do I know if my patio slab can hold a solarium?

    Check that the slab sits higher than the ground around it and has no large buckling, since those two things usually decide it. Duralum, a sunroom maker, says in its guide that the slab must sit above the surrounding ground because standing water can get into the tracks and the room, and that small hairline cracks are fine while large buckling needs repair first. I check both on the estimate visit and put any repair in writing before the room goes up.

  • Can you build a solarium on a wooden deck?

    Often you can, as long as the deck and its footings can carry the room all the way down to the ground. The industry's sunroom specification calls for every sunroom, on a concrete slab or a wood deck, to carry its forces in an unbroken path to the foundation, so I look under the deck before we plan anything. Our deck-to-sunroom conversion page explains that work in more detail.

  • Does a solarium count as living space?

    Under the industry's sunroom specification, a heated or cooled room that opens to your house counts as habitable, conditioned space. That means its windows have to meet requirements for keeping out air and water and for heat control, which is a large part of what sets a solarium apart from a seasonal enclosure.

  • How do I take care of a solarium once it's built?

    Look over the roof and gutters once a year and keep the door and window tracks clean, and that covers most of it. One maker's construction guide suggests that yearly check, keeping foot traffic on the roof to what's needed, and cleaning tracks with pure silicone spray, since oil-based lubricants tend to attract dirt. It also says to keep the weep holes, the small drain openings, clear so water drains properly.
