Request an estimateWhat does a custom sunroom in Montclair involve?
A custom sunroom in Montclair is an enclosed room we design and build onto your house. It can be anything from a screened porch to a heated and cooled room that works much like a regular addition, sized and laid out for the way you'll use it.
Most of our calls come from homeowners with a covered patio, a slab or a deck who want more out of it, and some of those jobs end up as a straight patio-to-sunroom conversion. The price moves with the size of the room, whether it needs a foundation, whether it's heated and cooled, and what it has to sit on. The schedule depends on how quickly we settle the design and how long the city's plan review takes. The on-site estimate is where you get a number for your own room.
How we build a custom sunroom
Custom means we start from your house and the way you'll use the room, not from a catalog. I measure, look at what the room will sit on and how it ties into your roofline, and sketch it out with you before we price it. That's when we settle the big choices, because insulated windows and insulation in the walls, floor and roof are much easier to put in while the room goes up, and adding them later often costs more. Once the plans are approved, our crew gets the base ready, frames the room, sets the roof and windows, and cleans up before we walk through it with you.
If you already know the layout and just need it built, our sunroom construction work covers everything from framing through finish. If you've got a sunroom that's drafty, dated or just not working for you, sunroom remodeling is often a better place to start than a new room.
Building a custom sunroom in Montclair
Most building permits in Montclair are pulled in person, over the counter at City Hall. A licensed contractor, you as the owner or an agent for either can pull one. When your room needs a permit, we prepare the plans, handle the city paperwork and keep you posted on where it stands, and we'll tell you at the estimate who's pulling it. At plan check, the city can ask for structural and energy calculations for additions from someone licensed by the state. We line those up from the start, because every revision round adds another review to your schedule.
Most of the backyards we see in Montclair already have a covered patio, a slab or a deck, and what's under it decides a lot of the job, so I check it before we draw anything. We're based in Montclair and see the same setups on jobs in Ontario, Upland and the other cities around it.

Frequently asked questions
How much does a custom sunroom cost near Montclair?
A sunroom in the San Bernardino area usually costs about $95 to $195 per square foot, and that's the regional market range, not our price. Larger rooms that need a foundation and have heating and air conditioning land at the high end. One San Bernardino price report for a three-season room leaves out insulation, extending heating or cooling, plumbing and permits, so ask what each bid includes. Your own number comes from the on-site estimate.
What is the difference between a three-season and a four-season sunroom?
A four-season room is heated and cooled and has all-weather windows, while a three-season room generally isn't heated or cooled and has uninsulated windows or screens. That choice decides when you can use the room and what goes into building it. If you want a room you'll use every month, I'd go four-season. If it's mostly for evenings and weekends, three-season keeps you from paying for heating and cooling you won't use.
Can a sunroom go on my existing deck?
It can, but a deck will typically need extra beams, posts or footings to carry the weight of a new sunroom, so plan for that in your budget. The National Sunroom Association advises asking a local structural engineer whether your deck is suitable. I'll look at the framing at the estimate, and our deck-to-sunroom conversion page covers that job in more detail.
How long does plan review take in Montclair?
When the city is at normal volume, Montclair's first plan review takes about 2 weeks, and each review after that takes about 1 week. Every round of revisions adds time before work can start, which is why we try to get the drawings complete the first time.
Can I draw my own plans for a patio cover or small addition in Montclair?
Yes, for very small projects that don't need engineering, such as patio covers and one-story wood frame additions, the city lets owners prepare their own drawings. They have to be clear, drawn to scale and include the details needed for approval. If your room needs engineering, we prepare the plans as part of the job.
How do I get an accurate price on a custom sunroom in Montclair?
Call us at (909) 738-1507 or send the form with the rough size of the room, the type you want and whether it sits on a deck, a slab or an existing patio. I'll come out, measure and look at what's underneath, so the price is based on your actual space.
