How do you know it's time for a custom sunroom?
Patio too hot to use
You have a patio out back, but by midday the sun makes it miserable and nobody goes out there. That usually means the space is already there and just needs walls, glass and a roof that keep the heat in check, so waiting means another summer of space you're not using.
Stains where roof meets house
Water marks or peeling paint where an old room or patio cover joins the house usually mean the joint was never sealed or sloped right. Left alone, that water works into the framing and the house wall, and the repair grows every rainy season.
Standard sizes don't fit
Your roofline, an odd corner or a sloped yard doesn't match the stock sizes you've priced out. Forcing a kit into that space leaves gaps and awkward roof joints that leak, so it's better to build to your measurements from the start.
What goes into a custom sunroom in Chino?
A custom sunroom in Chino, CA is a room we build onto your house to your measurements, set on a base that can carry it and fitted with windows, siding, roofing and electrical access. The big choice up front is three-season or four-season, because that decides whether the room gets heating and cooling at all.
Most people who call us have a patio, slab or deck out back and want it to work as a real room, and I'd rather tell you straight what that base can handle before anything gets sold. The price moves with the size, the room type and how much work the base needs, and the schedule turns mostly on that base work and the city's review. Your own number comes from the estimate, because I measure, look at what the room will sit on and write up what we'd build. We're based in Chino and work in the cities around it.
Details to note before an estimate
- Rough size of the room you want
- Three-season or four-season use
- Slab, deck or bare ground underneath
- Cracks or settling in the slab
- How you'll use the room day to day
How we build a custom sunroom
I start with what the room sits on, because custom starts there and a nice room on a weak base will sag. I check the slab, deck or ground, and if it can't carry the room, I tell you what it needs before we ever talk about windows. Next we settle insulation for the windows, walls, floor and roof in the design, since it's much easier to put in during the build and adding it later can often cost more. The roof matters most, because on a midsummer day a square foot of roof takes in roughly three to four times the sun of a north- or south-facing wall. Then our crew frames the room, ties the roof into your house with a slope that sends water away from it, and fits the windows, siding, roofing and electrical access.
Sometimes the job is a little different from a new room we design with you. If you already have the layout settled and just need it built right, our sunroom construction work covers the framing, roof and finish. If you have an older room that leaks, runs hot or feels dated, sunroom remodeling can fix the base, the roof joint or the windows without tearing the whole thing down.
Other sunroom work we do
Sunroom construction
When your plan is already set and you need a crew to put up the frame, roof and glass the right way.
Sunroom remodeling
For a room you already have that's leaking at the house, baking in summer or just not getting used.
What happens after you call about a custom sunroom?
Call and set a visit
You call or send the form, and we set a time for me to come out. Mention anything you already know, like the room type you're leaning toward or whether it would sit on a deck.
I measure and write it up
I come out myself, measure the space, check what the room will sit on and ask how you plan to use it. You get a written estimate that spells out what we'd build and what it sits on, so the base work isn't a surprise later.
We handle the city side
Once you sign, we take care of the city side, so you're not running paperwork back and forth yourself. We keep you posted until it clears.
Build it and walk it
My lead installer runs our own crew on site through the build. When it's done, I walk the finished room with you and we go over the roof joint and where the water goes.
Questions before you book a custom sunroom
What does a custom sunroom cost near Chino?
A three-season sunroom, installed, usually runs about $100 to $150 per square foot in San Bernardino County. That common figure leaves out insulation, extending heating or cooling, plumbing and permits, and larger rooms that need a foundation and have heating and air conditioning land at the higher end. Your written estimate shows what your room would actually need.
What is the difference between a three-season and a four-season sunroom?
A four-season room is fully enclosed, heated and cooled, with all-weather windows, while a three-season room isn't heated or cooled and uses uninsulated windows or screens. That choice decides whether the room has temperature control at all, so I ask how you'll use it before we pick one.
Can a sunroom go on my existing deck?
Often it can, but a deck typically needs extra beams, posts or footings to carry the added weight of a sunroom. Plan that upgrade into your budget from the start, and I'll tell you what your deck needs once I've looked underneath it.
Who handles sunroom permits in Chino?
In Chino, the city's Development Services Department processes building and planning permit requests, and the city posts plan submittal steps for room additions. We check with the city's building office about your address, take care of the paperwork it asks for and keep you posted as it moves along.
How do I keep a sunroom from leaking?
Ask your installer how they handle drainage, roof slope, sealing and the joint with the house, because one maker's guide says leaks usually start there. Those are the parts I watch closest, and one maker's owner guide also suggests checking the roof and gutters once a year and staying off the roof unless you need to be up there.
How do I check a sunroom contractor in California?
A contractor in California has to keep a $25,000 contractor's bond on file with the Contractors State License Board. State rules also say any change to a home improvement contract has to be in writing, legible and easy to understand, and has to tell you of your right to cancel. We're fully licensed and insured, and we're glad to walk you through how we work.
