How do you know your patio needs a three-season room?
Patio empty by afternoon
You've got a covered patio, but nobody's out there once the afternoon sun swings around. That usually means the space needs walls and planned shade, not just a roof, and every summer you wait is another one where that space goes to waste.
Dust and bugs on everything
The furniture needs wiping before anyone sits down, and the bugs show up at dusk. An open patio can't keep any of that out, so the longer it goes, the more cushions, grills and screens you end up replacing.
Stains where cover meets house
Look for dark streaks on the stucco or fascia right under the patio cover. That's usually water getting past the spot where the cover ties into the house, and if it keeps going, the wood rots and enclosing over it later just traps the problem.
Is a three-season sunroom the right fit for your Chino home?
A three-season sunroom in Chino, CA is a ready-made wall and roof system we add to the back of your house, with glass walls and no heat or air. It gives you extra living space out of the dust, bugs and wind that works for most of the year, as long as it's planned around summer sun.
Most people who call us have a slab or patio cover out back they barely use, and they want a real room there without building a full addition. The price mostly moves on the size, what the room sits on, and how much glass you want and where, while the schedule moves on the city's plan review and any work the base needs first. We're fully licensed and insured, and we check with the city's Building Division about your address and handle the paperwork it asks for. Your own figure comes from the written estimate after I've been out to see the space.
Details to note before an estimate
- Rough size of the room you want
- Existing slab, deck or patio cover
- Which way the back of the house faces
- How you plan to use the room
How we build your three-season sunroom
I start with what the room will sit on, because a slab that's cracked, out of level or too thin decides the job before the glass does. Then we lay out the room and settle the glass and shade together, since summer sun is the big question in a room with no heat or air, and I'll steer you away from more east and west glass than you need. My lead installer and our own crew set the frame on the base, stand the wall and door panels, then put the roof on and tie it into the house so water runs off and away instead of down your stucco. We clean up as we go, so you're not left with a yard full of scraps.
If your patio cover is sound and you'd rather close in what you have, patio enclosures can be the simpler route. When the space has an odd shape or you want something a standard system won't give you, we build custom sunrooms too.
Other ways to add room out back
Patio enclosures
Walls and windows added under the patio cover you already have, when its roof and posts are still in good shape.
Custom sunrooms
A room drawn around your house and lot, for layouts and looks a ready-made system won't fit.
What happens when you call about a three-season sunroom in Chino?
Call or send the form
You call (909) 413-6398 or fill out the form, and we set a time for me to come see the space. Evenings and weekends work too, since we answer seven days a week.
I come out and measure
I come out myself, measure, look at what the room will sit on and ask how you plan to use it. That tells me which way the glass should face and how much shade the room needs.
You get a written estimate
It spells out what we'd build and what it sits on, so you can see where the money goes before you sign anything. If the slab or cover needs work first, it's written in there, not sprung on you later.
We build and walk through
Once you sign, we handle the city side and my lead installer runs our own crew on the build. When it's done, I walk the finished room with you.
Questions before you book a three-season sunroom
How much does a three-season sunroom cost near Chino, CA?
A three-season room added to an existing structural base, like a sound slab or deck, usually costs about $100 to $150 per square foot with installation labor, going by prices in nearby Ontario and San Bernardino. Those per-foot figures leave out insulation, extending heating or cooling, plumbing and pulling permits, so each of those adds to the total. Your own number comes from the written estimate after I've seen what the room sits on.
What's the difference between a three-season and an all-season sunroom?
A three-season room has single-pane windows, and an all-season room has insulated walls and windows. If insulation is what you're after, you're really shopping for an all-season room, and I'd rather tell you that up front than sell you the wrong one.
How do I keep a sunroom from overheating in Chino summers?
Block the sun before it hits the glass, with overhangs or a porch roof, movable awnings, shutters, plants that shade the east and west windows, and less glass on those two sides. One trade group's design guide also warns that sloped glass overhead can overheat a room, while upright glass costs less and is easier to keep from overheating. If you still want glass overhead, plan on more design work and a higher price.
How do I know if my patio slab can hold a sunroom?
Have it looked at before anything's ordered, and find out whether it's a post-tension slab before anyone cuts or breaks it. Another city's building handout warns that cutting a tendon, one of the steel cables inside that kind of slab, can be very dangerous and expensive to repair. I check the base at the estimate, so you'll know before you sign.
Does living in a Chino fire zone change what I can build?
It can if your lot is in the high zone. A newer map rates some areas in southern Chino, including parts of The Preserve and Prado Dam, as Very High, High or Moderate fire hazard severity zones, and the Chino Valley Fire District says new construction or additions in the high zone have to meet building standards for the wildland urban interface, where homes meet open land. Moderate-zone properties currently have no legal requirements, but the city's zoning rules still limit where a structure can go on your lot and how tall and big it can be.
What are three-season sunroom roofs made of?
Most three-season sunroom roofs are insulated aluminum panels, and thicker panels hold more insulation and can span farther. Some sunrooms now use polycarbonate roof systems instead, and one maker describes its sunroom materials, mostly aluminum with some vinyl and fiberglass, as maintenance-free.
