How do you know it's time for an all season room?
Patio empty most months
You've got a cover and a slab out back, but nobody sits there when it's hot, cold or windy. Usually the space is fine and what's missing is walls, glass and a way to heat and cool it, and every year you wait is another year of a patio you don't use.
Old enclosure too hot
An older screen or glass enclosure that turns into an oven by mid-afternoon usually wasn't built to be heated and cooled, so the door just stays shut. Fans and a window unit rarely fix that, and the longer it sits, the more it turns into storage.
Stains where it meets the house
Water marks on the ceiling or siding where your patio cover meets the house usually mean the flashing, the metal that turns water away from that joint, is failing. Left alone, that water gets into framing you can't see, and building a room over it only hides the problem.
What is an all season room, and what does it take in Chino?
An all season room is a sunroom built to be used in every season. In Chino, CA we build them as one-story rooms attached to your house with a lot of glass in the walls, and we plan the heating and cooling up front so you can sit in it any month of the year.
Most people who call us already have a slab, a deck or a patio cover out back and want a room they'll actually use. Often that's a patio-to-sunroom conversion, but first I need to see what the room will sit on and how the roof will tie into the house, because those two things move the price and the schedule more than the glass does. After that, the size, the windows and roof you pick, how the room gets heated and cooled and how long the city takes with the plans all play a part. Your written estimate spells out what we'd build and what it sits on, so you know where the money goes before you decide.
Details to note before an estimate
- Rough size of the room you want
- Existing slab, deck or patio cover
- How you plan to use the room
- Your current heating and cooling system
How we build an all season room
I start under the room. I look at your slab or deck and tell you straight whether it can carry a glass room or needs new footings, because a room is only as good as what it sits on. Next comes heating and cooling. Your air system was sized for the house you have now, so we plan how the new room gets heated and cooled before we build, instead of hoping the old system keeps up. Then my lead installer runs our own crew on site, setting the frame, tying the roof into the house, flashing that joint so water runs away from it and closing in the walls and glass. We won't hang a roof off a wall that can't carry it or skip flashing to save a day, because a pretty room that leaks or sags isn't worth the glass in it.
Not everyone needs a full year-round room. If you mostly want walls around the patio you already sit on, enclosed patio rooms usually do the job with less to heat and cool. If you want glass overhead and as much light as you can get, solarium installation gives you that, but a glass roof takes more work to keep comfortable. For a room you'll use every day, I usually lean toward a solid roof for that reason.
Other rooms we build out back
Enclosed patio rooms
A good fit when you want shelter from wind and bugs on the patio you already have and don't need it fully climate controlled.
Solarium installation
For the most light possible, with glass overhead as well as on the walls, and a cooling plan to match.
What happens when you call about an all season room in Chino?
Call and set a visit
You call or send the form, and I come out to see the space and measure it. I'll ask how you plan to use the room, because that decides the glass, the roof and the heating and cooling.
Get a written estimate
You get a written estimate that spells out what we'd build and what it sits on. If the slab needs work or the room needs its own heating and cooling, you'll see it there, not halfway through the job.
We build, then walk it
Once you sign, we handle the city side and my crew builds the room. When it's done, I walk the finished room with you.
Questions before you add an all season room
How much does an all season room cost?
Across the US, a four-season sunroom, which is the same thing as an all season room, usually costs about $120 to $175 per square foot in total. That's a national figure, not our price. The size, the glass and roof you pick, what the room sits on and how it's heated and cooled move your number, and your estimate spells out what we'd build and what it sits on.
Will my central air keep up with a new all season room?
Often it won't, because most central systems are sized for the house as it was built, and one sunroom builder notes that adding a room can push the system past what it can handle and leave the whole house warmer. If the room does share your system, state energy guidance says the extended ducts have to meet duct insulation and leakage requirements, so that work becomes part of the job. I'll go over both routes with you before anything is drawn.
How do I know if a sunroom builder's license covers structural work?
Ask the builder directly, because California doesn't let a residential remodeling contractor contract for structural changes to load-bearing parts of a house, such as footings, foundations, load-bearing walls and the roof structure. An all season room usually ties into your walls or roof, so that question matters on this job. We're fully licensed and insured, and I'll show you where the room ties in when I'm out.
How much can a contractor ask for up front on a sunroom in California?
On a home improvement job in California, a contractor can ask for a down payment of no more than $1,000 or 10 percent of the contract price, whichever is less. Any later payment has to be listed clearly in the contract and based on work already done or materials delivered to your house. Ask to see that schedule before you sign, so you're never paying far ahead of the work.
How do I get a permit for an all season room in Chino?
We handle it. Chino's Development Services Department processes building permit requests, and we check with the city about your address, take care of the paperwork it asks for and keep you posted as it moves. For room additions, the city's checklist asks for a plot plan drawn to scale showing your lot, how far existing buildings sit from the lot lines and the new room, plus plans showing the insulation in the walls, ceiling and any raised floor meets the state energy code.
Do fire zone rules apply to an all season room in south Chino?
They can, because the city's fire hazard map put some areas in southern Chino, including parts of The Preserve and Prado Dam, into Very High, High or Moderate fire hazard zones. The Chino Valley Fire District says additions in its Very High or High zones must meet building standards for homes that border wildland, while the Moderate zone currently has no legal requirements. We check your address before we design, so the room is drawn to the rules that apply to it.
