Request an estimateWhat is an all season room, and is it right for my patio?
An all season room in Montclair is a sunroom with enclosed walls, all weather windows and its own heating and cooling, so you get a room joined to your house that you can use in every season instead of an enclosed porch.
Most of our calls come from people with a covered patio or a deck that only gets used part of the time, and an all season room turns that space into one you'll use like any other room in the house, often as a patio-to-sunroom conversion. The price moves with the room's size, whether your slab or deck can carry the room or needs a new foundation, the windows and insulation, and the heating and cooling. The schedule turns mostly on the plans, the city's review and how early you settle the big choices, and the estimate is where you get a number for your own space.
How we build an all season room
First we help you decide whether the room opens up to the house or stays closed off with its own heating and cooling, since that one choice shapes the walls, the doorway and how the room is heated and cooled. Then we pin down the windows and the insulation for the walls, floor and roof, because they go in far more easily while the room is going up than they do later, when adding them usually costs more. Once the plans are approved, our crew gets the floor ready, frames the walls and roof, sets the windows, puts in the insulation and the heating and cooling, and cleans up before the final inspection.
Not every patio needs a full all season room. An enclosed patio room closes in the space you already use, and solarium installation puts glass overhead as well as along the walls.
Planning an all season room build in Montclair
If your all season room needs a building permit, the City of Montclair lets a properly licensed state contractor, the owner or an agent for either one pull it. 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. For a room addition, the city says plans can usually be drawn by a qualified person such as a draftsperson, though larger projects may need a California licensed architect or engineer to prepare and sign them. Inspections are booked for the next day only when they're requested before 5:00 p.m. the day before, and since the city is closed every Friday, a Thursday request lands on Monday, so we plan the build around that. California's Energy Code also sets energy efficiency rules for additions, which is one more reason we settle the windows and insulation before anything goes up.
Around Montclair we mostly meet covered patios and backyard decks on houses people already live in, so a good part of the job is working out what the existing slab or deck can carry. We do the same work in Ontario, Upland and the other cities around us.
Why call us for an all season room
I measure before we plan
I come out myself to look at the job and measure, and our crew lead runs the build with our installers. That way the room we talked through in your yard is the room the crew builds.
Licensed and fully insured
We work licensed and fully insured on every all season room we build. Ask to see both when I come out, before you sign anything.
Patios into rooms since 2017
I started this business in Montclair in 2017, and turning patios, decks and slabs into rooms people use is what we're best known for. We've usually seen what's under an old patio before we ever open yours up.
Plans ready for Montclair's review
The city normally wants a site plan, floor plan, elevations and structural, electrical, plumbing, mechanical and energy calculations with a permit, and we prepare them. A complete set going in helps avoid extra rounds of review before your build can start.

Frequently asked questions
How much does an all season room cost in Montclair?
A sunroom in the San Bernardino area usually costs about $16,000 to $115,000 per project, and that's the area's usual range, not our price. Larger rooms that need a foundation and have heating and air conditioning fall toward the higher end, and an all season room always includes the heating and cooling. Your own number comes from the estimate, once I've seen your space.
How do I choose between a four season and a three season sunroom?
Pick a four season room if you want a heated and cooled space with all weather windows, and a three season room if an enclosed porch with uninsulated windows or screens will do. An all season room is the four season kind. I'll ask how you plan to use it, because I'd rather you not pay for heating and cooling you won't use.
Should my all season room open to the house or be closed off?
Open it to the house if you want it to live like part of your home, and close it off with its own heating and cooling if you want a separate room you can shut. One national industry sunroom specification calls a heated or cooled room open to the house habitable and one closed off with its own heating or cooling non-habitable, so the choice also decides which of those classes your room falls in. That's why we settle it before anything else.
How long does plan review take for a sunroom in Montclair?
Plan review in Montclair takes about 2 weeks during normal building activity, and each later review takes about 1 week, according to the city. We build those weeks into your start date so you know when the crew can realistically begin.
What is the best frame material for an all season room?
There's no single best frame, but one San Diego builder says an aluminum frame for a four season room needs a thermal break, a nonconductive strip that stops heat moving through the frame and keeps condensation from forming inside. The same builder says wood and vinyl frames resist heat transfer on their own. We'll talk through which frame suits your room at the estimate.
What license does a contractor need to build a sunroom in California?
California's contractor licensing board defines a general building contractor's main business as structures that shelter and enclose people or property and take at least two unrelated building trades to build. An all season room encloses people and usually takes framing, windows, insulation and heating and cooling work, so it fits that description. Ask us about our license when I come out.
Other rooms we build
Enclosed patio rooms
A good fit if you want your patio closed in and usable without committing to a fully heated and cooled room.
Solarium installation
Worth a look if you want glass in the roof as well as the walls, so the room fills with light from above.
