Patio-to-sunroom conversion in Montclair CA - a room you'll actually use

Most of my calls come from people with a covered patio that's too hot in summer and too chilly on winter nights to sit in, and they want more out of it. The price mostly comes down to the size of the room, whether we can build on your slab and cover as they are, whether you want screens or insulated glass, and whether the room gets heating and cooling. If shade and a screen are all you're after, a simpler patio enclosure may be plenty. The schedule turns on the plans, the city's plan check and inspections, and what we find in your slab, and you'll get a figure for your own patio once I've measured it at the estimate.

I start by measuring the patio and looking at the slab, the cover and where they meet the house, then we settle the big choices with you up front, like screens or windows, insulation and what's under the floor, because I'd rather get those right now than fix them later. Before anyone cuts into the slab, we find out what's inside it, since some slabs have steel cables under tension that are dangerous and costly to hit. Then we firm up the base where the walls need it, frame the walls and roof, tie the room into the house, set the windows and doors, and finish and clean up so you're left with a room and not a job site.

If your outdoor space is a raised wood deck instead of a slab, a deck-to-sunroom conversion works much the same way but starts with the deck framing. And if you already know you want a room you can heat and cool year round, take a look at our all season rooms, because that choice shapes everything from the glass to the roof.

In Montclair, the city's building division issues building permits, checks the plans and inspects the work on site, so they're the ones who decide whether your conversion needs a permit. I won't guess at that for your job before I've seen it, and the city is the place to ask. When a job does need a permit, 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 it. We're based in Montclair and work in Pomona, Chino and the other cities around it too.

Most patios we see here are concrete slabs off the back of the house, often with a cover already over them, and summers are hot enough that people want to know how the room will feel in August before anything else. We see the same setups on jobs in Ontario and Upland, so we talk through glass, shade and cooling at the estimate instead of after the walls are up.
