Request an estimateWhat goes into building a sunroom in Montclair?
Sunroom construction in Montclair adds an enclosed room with windows or screens to your house, anything from a heated and cooled four-season room to a simple screened porch, so you get real use out of the space behind your home.
Most people who call Solcraft Montclair Sunrooms & Patios have a covered patio, a deck or an old slab out back that gets used a few weekends a year, and they want a room they'll actually sit in. The price moves with the room type, the size, how much glass and insulation go in and what the room sits on, because a deck or slab that can't carry the weight needs work before the walls go up. The schedule mostly turns on the city's plan review and any engineering the base needs, and the estimate is where your own figure comes from. We're based in Montclair and build in Ontario, Pomona, Upland, Chino and the other cities around it.
How we handle sunroom construction, start to finish
I start by measuring the space and checking what the room will sit on, then we settle the room type, the insulation and the floor before anything gets drawn, because those are the choices that are hard to undo once the walls are up. From there we prepare the plans, and once any permit is in hand our crew lead takes over and stays on your job from start to finish, so one person knows every detail. The crew fixes or builds the base first, frames the walls and roof, sets the windows or screens, finishes the inside and hauls the mess away.
If you already have a sunroom that's leaking, baking or just worn out, sunroom remodeling usually makes more sense than tearing it down and starting over. And if all you want is shade and evenings without bugs, screen room installation is a simpler build that skips most of the insulation questions.
Sunroom construction in Montclair, from permit to plans
When a sunroom needs a permit here, Montclair City Hall issues it, and most permits are handled in person over the counter. A licensed contractor, the property owner or an agent for either can pull it, and for a room addition the city says a qualified draftperson can usually draw the plans, while larger projects may need plans signed by a California licensed architect or engineer. We prepare the plans, handle the city paperwork and keep you posted on where it stands, and I'll tell you at the estimate who's pulling the permit.
Most of what we build on in Montclair is a covered patio on a concrete slab or a wood deck that's taken years of sun, and either one gets checked before we plan walls on it. We see the same mix on jobs in Ontario and Upland, and the hot summers are why we talk hard about glass and roof insulation on any room you plan to use in July.

Frequently asked questions
How much does a sunroom cost in Montclair, CA?
A three-season room added to an existing structural base usually costs about $100 to $150 per square foot in San Bernardino County, installation labor included. A four-season room, or a base that needs work first, usually runs higher. One local price report leaves out insulation, extending heating or cooling, plumbing and permits, so ask any contractor whether their quote covers those.
What is the difference between a three season and four season sunroom?
A four-season room is enclosed, heated and cooled, with all-weather windows, while a three-season room isn't heated or cooled and uses uninsulated windows or screens. The choice comes down to how much comfort control you want. If you'll mostly use it spring and fall, I'd rather not have you paying to heat and cool a room you use like a porch.
Can a sunroom be built on my existing deck?
Often it can, but a deck under a new sunroom will typically need added beams, posts or footings to carry the extra weight. A local structural engineer can tell whether your deck is suitable, so that check comes first before we plan the room.
How long does it take to get a sunroom permit in Montclair?
During normal building activity, the city's first plan review takes about two weeks, and each review after revisions takes about another week. The city may also ask for structural calculations at plan check, so we get the engineering ready early and build that wait into the schedule before we set a start date.
Is it better to insulate a sunroom during construction or add it later?
During construction, because highly insulated windows and insulated walls, floors and roof are much easier to install while the room is being built. Adding them later can often cost more, which is why we settle insulation while we're planning the room.
What is the best way to keep a sunroom cool in summer?
Shade the glass from the outside. One sunroom builder's guide says exterior shades, like awnings or exterior roller shades, work better than interior shades because they stop the sun before it gets through the glass. Pair that with the insulation choices above and the room stays usable on hot afternoons.
