Vinyl sunrooms in Montclair CA - a room that fits the way you'll use it

Most people who call us already have a covered patio or a deck and want more out of it, and the first thing I'll ask is how you plan to use the room, because whether it gets heating and cooling decides a lot of what follows. That choice, the size of the room and whether it can sit on the base you have or needs a new foundation move the price most, while the schedule mostly turns on city plan review and inspections when a permit is needed. Starting from a slab under a patio cover is the kind of patio-to-sunroom conversion we do most, and when I come out to measure we'll go over those choices for your space.

We start by measuring the space and looking at what's under it, and then I show you how a vinyl room would sit on your house, where it meets the wall and the roofline and where the doors land, so you can picture it before you commit. Next we settle the big choices, like insulation and the floor, because those are much harder to change once the walls are up. Once the plans and any permit are in hand, our crew builds the room, and before we leave we walk you through a simple yearly check of the roof, gutters and door tracks so you know what to keep an eye on.

If you'd like the room to open straight into the house and live like part of it, that's the work we do as sunroom additions. If you know you'll use it every month and want it heated and cooled, our four season sunrooms are planned around that from the start.

Montclair's building staff issue building permits, check plans and inspect the work on site, and most submittals need drawings plus structural and energy calculations. When your room needs a permit, we prepare those plans, handle the city paperwork and keep you posted on where it stands. Plan review takes about two weeks when the city's building activity is normal, and about a week for each later review after revisions, which is often the longest wait before the build starts. Inspections are booked through the city's request line, and a request in before 5 p.m. gets the next day, but the city is closed every Friday, so one made on Thursday lands on Monday.

We're based in Montclair and work in Ontario, Pomona, Upland, Chino and the other cities around it, and most of what we see is a covered patio or deck behind the house, often with a slab already poured. We see the same setups on jobs in Ontario and Upland, so we look closely at how the room meets the house and what's under it before we draw anything.
