Four season sunrooms in Montclair CA - a room you can use every month of the year

Most people who call us already have a covered patio or a deck and want a real room out of it, one they'll sit in during the hot months and the cold ones, not just on nice weekends. The price moves mostly with the size of the room, the materials you pick and what it sits on, because an older slab or deck may need work before it can carry insulated walls and glass. The schedule turns on how fast the big choices get made and how long the city takes with the plans. At the estimate I'll measure, look at your foundation and your heating and cooling, and give you a number for your own room.

I start with your heating and cooling, because the big question on a room you'll use all year is whether your system can take on the extra space. I look at it on the first visit, and we plan around what we find before the design is set, whether that means tying into your ducts or giving the room its own unit. We settle the insulation and what goes under the floor at the same time, since those are the costly things to change once the walls are up. Then we draw the plans, and our crew builds the room from the foundation and framing through the glass, wiring and trim, and we clean up before we hand it over.

Not everyone needs a room that's heated and cooled. If you mostly want the space from spring through fall, a three season sunroom skips the insulation and HVAC and costs less to build. And if you just want to close in what you have against bugs, dust and wind, patio enclosures do that without turning the patio into a full room.

The City of Montclair issues the building permit, and for a room addition it wants three sets of detailed plans showing the framing, electrical, mechanical and plumbing, along with energy compliance forms. Those energy forms carry real weight on a four-season room, because California's Energy Code sets efficiency rules for additions, and its standards for the walls, roof, windows and doors depend on the climate zone your house sits in. When a job needs a permit, we prepare the plans and the forms, handle the city paperwork and keep you posted on where it stands.

A lot of the Montclair homes we see have a covered patio on an older slab that usually wasn't poured with a closed-in room in mind, so I check its condition and edges before we plan anything on top of it. We run into the same patios and slabs on jobs in Ontario and Upland.
