All season rooms in Norco CA - a room you can use every month of the year
Your patio sits empty most of the year. We build a sealed, comfortable room off your house that you'll sit in any month.

Do you need an all season room, or will a simpler sunroom do?
An all season room is a fully enclosed room with all weather windows and its own heating and cooling, so you can use it any month of the year. We build all season rooms in Norco, CA for homeowners who want a real room off the house, not a porch they use a few weekends a year.
Most people who call me have a patio, a deck or a tired old enclosure that sits empty most of the year, and the first question is whether you really need heat and air or whether a three season sunroom fits how you'll use it. The price moves with the size, whether the room needs a new foundation and whether you add heating and air conditioning, since bigger rooms with a foundation and heat and air cost the most. The schedule turns mostly on the design and on any permit and inspections, and the written estimate I give you spells out what's included and what isn't.
How we build an all season room
I start by asking how you'll use the room, because if you'll only sit out there in spring and fall, I'd rather build you something simpler than charge you for heat and air you won't run. If you do want it year round, the insulation and the roof edge go into the first drawing, since insulated windows, walls, floor and roof are much easier to put in during the build and adding them later often costs more. Then our crew sets the footings or gets the slab ready, frames the walls and roof, sets the windows and doors, insulates, ties the room into the house and finishes the inside, with the heating and cooling going in as part of the build. We seal the base where the room meets the ground, because a room that lets water in at the bottom is money wasted.
If you'd like your patio closed in more simply, take a look at our enclosed patio rooms. If you want glass overhead as well as on the walls, we also do solarium installation, and the same planning for insulation and sun applies there.
What changes an all season room job in Norco
Once a room is heated or cooled and opens to your house, California treats it as an addition, because the state's guidance counts any change that adds conditioned floor area and volume as one. The state Energy Code then sets energy, water and indoor air quality requirements for that addition, and a design can meet them with methods already known to be efficient or with a performance approach that allows more freedom if the room comes out just as efficient overall. Your city or county building office decides whether your job needs a permit, and when it does, we put the application together, deal with that office and set up the inspections.
Suncrest Norco Sunrooms & Patios is based in Norco and builds all over the cities around it, and most jobs here start with a back patio, a deck or an old enclosure someone wants to get more out of. We get the same kinds of houses and the same request on jobs in Corona and Eastvale, so the planning works the same way.

Questions before you build an all season room
How much does an all season room cost near Norco, CA?
A sunroom in nearby Riverside usually costs about $95 to $130 per square foot, and that's the going rate in the area, not a price from us. Where your room lands depends on the choices above, and your written estimate gives you the figure for your own room.
What is the difference between an all season room and a three season room?
An all season room has heating, cooling and all weather windows, while a three season room generally has no heating or cooling and uses uninsulated windows or screens. If you'd only use the room in mild weather, a three season room usually costs less and does the job, and I'll tell you so.
Does a sunroom closed off from the house count as living space?
Under the industry sunroom standard, a heated or cooled room open to the house counts as habitable, and one shut off from the house with its own heating or cooling control does not. That standard is industry guidance, and local building and fire code agencies can set different rules that win where the two disagree.
How do I keep summer sun from overheating a sunroom?
Roof overhangs can block direct summer sun from the windows while still letting the lower winter sun in. That's why the roof edge goes into the first drawing on our rooms, along with where the windows sit.
How do I keep sunroom windows and doors sliding smoothly?
One maker's care guide says to keep door and window tracks clean, inside and out, and to use a pure silicone spray so they run smoothly. The same guide warns against oil-based lubricant, because it tends to attract dirt.
Can I turn my existing patio into an all season room in Norco?
Often, yes, if the slab and the wall of the house can carry a fully enclosed, insulated room. I check the slab and where it meets the house on the first visit, and if it won't hold up, we plan new footings instead. Our patio-to-sunroom conversion page covers that job in more detail.
Why Norco homeowners call Suncrest Norco Sunrooms & Patios for all season rooms
I measure, our crew builds
I come out myself to look at the spot and measure, and our own crew does the build. The person who measured your wall is the person you call with questions, not a salesperson who's moved on.
Licensed in California, fully insured
We're licensed and fully insured. A room open to the house can mean new footings or a cut into a load bearing wall, and the state licensing board bars a residential remodeling contractor from contracting for that kind of structural change, so it's worth asking any builder what their license covers.
