How do you know it's time for a room you can use all year?
Room sits empty half the year
Your glass room or enclosed patio gets used on mild evenings, and nobody goes out there in July or January. That usually means it has glass but no insulation or heating and cooling, so every year you wait is another year of paying for space you can't use.
Stains where it meets the house
Water marks on the ceiling or wall where the room joins your house usually mean the roof wasn't tied in and flashed right. If you leave it, water works into the framing of the house itself, and that repair costs more than the room.
Cracked slab or sagging roof
A slab that's cracking or a roof line that dips usually means the room sits on something that wasn't built to carry it. Waiting lets doors and windows start to bind and glass seals fail, and those get worse every season.
Is a four-season sunroom right for your Chino home?
Four season sunrooms in Chino, CA are glass rooms built as part of your house, with insulation, electrical and heating and cooling, so you can use them in every season and not only the mild months. We're based in Chino and build them in the cities around it.
Most people who call us have a patio, slab or deck out back and want a room they'll actually sit in when it's hot or cold. Before anything gets sold, I tell you straight what your slab, deck or patio cover can handle, because a room you live in all year asks more of what's under it. The price moves with the size of the room, the materials and the foundation, and the schedule mostly turns on that groundwork and the city's plan review, which we handle as a fully licensed and insured builder. Your written estimate spells out what we'd build and what it sits on, so you see your own number before you decide.
Details to note before an estimate
- Rough room size you have in mind
- Slab, deck or patio it would sit on
- Whether it opens into the house
- How you plan to use the room
How we build a four-season sunroom
A room you use all year has to act like part of the house, so the first thing I settle with you is whether it opens to the house or stays closed off. That choice sets the rest of the plan. Then I look at what the room will sit on and tell you whether it can carry it or needs new footings. Our crew builds the floor, frames the walls and roof, insulates them, wires the room and puts in the heating and cooling. The part I watch hardest is where the roof ties into your house and where the water goes, because that's where a nice-looking room starts to leak.
If the room is mostly for spring and fall evenings, a three season sunroom may be all you need. If you just want to close in the patio you already have, take a look at our patio enclosures.
Other ways to add a room out back

Call and set a visit
You call or send the form, and we set a time for me to come out. I look at the space, measure it and ask how you plan to use the room.
Get your written estimate
You get a written estimate that spells out what we'd build and what it sits on. If your slab or deck can't carry the room, it says so before you sign anything.
We handle the city side
Once you sign, we check with the city's building office about your address and take care of the paperwork it asks for. We keep you posted as it moves along.
Build and walk the room
My lead installer runs our own crew on site while the room goes up. When it's done, I walk the finished room with you.
Questions before you book a four-season sunroom
How much does a four-season sunroom cost in Chino?
Across the US, adding a four-season sunroom usually costs about $200 to $400 per square foot. That's a national figure for the market, not our price for your house. For a Chino number, I come out and write up your estimate on site.
What's the difference between a four-season and a three-season sunroom?
A three-season sunroom is enclosed in glass too, but it has no insulation or heating and cooling, so it's comfortable only when the weather is. Pick the four-season build if you want the room comfortable year-round.
How do I decide whether my sunroom should open to the house?
Start with how you'll use it, because one industry sunroom spec treats a room that opens to the house and is heated or cooled as regular living space. A room closed off from the house runs on its own separate heating or cooling control instead. Settle it before design starts, since everything else follows from it.
What is the best foundation for a four-season sunroom?
A site-built sunroom needs a proper building foundation, while a prefab kit can attach to an existing wooden deck or patio as long as the surface is level. Which one you pick decides how much groundwork the job needs, and I'll tell you straight whether what you have now can carry the room.
Which Chino office handles building permits for a sunroom?
The Chino Building Division issues building permits, takes in plans for review and sends inspectors to check the work against city code. In Chino the city's design criteria call for a soils report, a study of the ground under the building, the state energy standards for walls, windows and doors depend on the city's climate zone, and zoning limits how tall and how big a structure can be. We take care of that paperwork for you.
What license does a contractor need to build a sunroom with a roof in California?
California's contractor licensing board says a B general building contractor may take on roofing when it's part of a larger job, such as a room addition. Ask whoever bids your sunroom what license they hold. We're fully licensed and insured.
