Sunroom Additions in Bloomington CA - A Bright Room Built Onto Your Home
Patio or deck sitting unused? We add a glass-walled room that ties into your house, with heating and cooling if you want it.
What goes into adding a sunroom in Bloomington?
A sunroom addition in Bloomington, CA is a one-story room built onto your house with glass covering more than 40 percent of its walls and roof, so you get the light of being outside with a roof over your head. At Brightspan Bloomington Sunrooms & Patios, we're based in Bloomington and build these rooms in many of the cities around it.
Most people who call us have a patio, a deck or a tired old sunroom they never use, and they want a room they will. The price moves most with the size of the room, whether it needs a new foundation and whether it gets heating and cooling, because a bigger room that's conditioned year-round takes more to build. The schedule usually turns on the permit, which we take care of, and your estimate gives you the figure for your own room.
- Licensed and fully insured.
- Free estimates at your property.

What a sunroom addition can look like
How we build a sunroom addition
Before anything else, I work out where the room joins your house and whether it gets heating and cooling, because nearly every other choice follows from those two. Where it joins decides how the new roof ties into yours and what the room sits on, whether that's your slab, your deck or a new foundation. Heating and cooling decide the windows, how much insulation goes in and what goes on the plans. From there our crew sets the base, frames the walls and roof, puts in the glass and finishes the inside.
That second question is really a choice between two kinds of room. If you want a space you'll use like any other room in the house, that's a four season sunroom. If you'd rather keep it simpler and lighter on cost, a three season sunroom is often the better fit, and I'll tell you straight which one suits how you plan to use it.
Why Bloomington homeowners call Brightspan Bloomington Sunrooms & Patios for sunroom additions
I do every estimate myself
I come out to look at your house and write up the estimate, and our own crew does the building while I check the work as it goes. You deal with the same person from the first visit on, so what you asked for doesn't get lost on the way to the crew.
Licensed and fully insured for additions
We're licensed and fully insured. A sunroom is a real addition to your house, not a small repair, so that protection matters while a crew is working on it.
Rooms sized to county setbacks
San Bernardino County requires open space at the front, sides and rear of every structure, and the zoning district sets how much, whether or not a permit is needed. I measure where the room would sit before we talk sizes, so the room you plan is one that fits your lot.
Every choice explained, since 2017
We've been in business since 2017, and we're known for walking through each choice before anything gets built. I'd rather answer the same question twice at your kitchen table than have you wonder later why the room was built the way it was.
Satisfaction guaranteed on every job. When you're ready, call (909) 275-7071 or send us a message with the room size you picture, whether you want heating and cooling, and a few photos of where the room would attach to the house.

What happens after you call about a sunroom addition?
Call or send a message
Reach us at (909) 275-7071 or through the form, and we'll set a visit that works for you. We answer Monday through Friday from 6 AM to 9 PM, and weekends from 8 AM to 10 PM.
I look at your house
I come out, look at the slab or deck and where the room would join the house, and we talk through how you want to use the space. Then I write up your estimate from what we talked through, so the price matches the room you actually want.
We handle the permit paperwork
Once you're ready, we check whether the county or your city handles your address and take care of the permit paperwork with that office. The county asks owners to have every permit in hand before work starts, so building begins once that's done.
Our crew builds the room
Our own crew does the building, and I keep an eye on each stage as it goes up. If you want to know why something is being built a certain way, I'm the one you ask.
Questions about sunroom additions in Bloomington
How much does a sunroom addition cost near Bloomington, CA?
A sunroom in the San Bernardino area usually costs about $95 to $195 per square foot, going by cost guides for the city of San Bernardino. One of those reports prices a three-season room on an existing base to include labor, windows, siding, roofing, fixtures and electrical access, but not insulation, heating or cooling, plumbing or permits. So when you compare prices, check what each one leaves out, and your estimate from us gives you the figure for your own room.
Do I need a permit to add a sunroom in Bloomington?
Plan on needing one, and settle it before any work starts. The county's Building and Safety Office issues permits to build or alter any building, and its list names additions and enclosed patios, though not sunrooms by name. Permits come from the local office or the county's EZ Online Permitting website, and the plan set includes a plot plan, foundation, floor, framing and roof plans, plus energy information with heating and cooling calculations, which we put together as part of the permit step.
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 isn't heated or cooled and uses uninsulated windows or screens. That's usually the first decision on a sunroom, because it sets the windows, the insulation and much of the price. If you'll use the room every day, I'd lean four-season, and if it's mostly for evenings and weekends, three-season is often plenty.
Can an unlicensed handyman build a sunroom in California?
Not if the job needs a permit. State rules let an unlicensed person take a minor job only up to $1,000, and only when the job needs no permit and they have no employees. Since the county's permit list names additions and enclosed patios, plan on a licensed contractor for a sunroom.
What is the best way to insulate a sunroom?
Build the insulation in from the start. Insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is going up, and adding them later can often cost more. The state's Energy Code also sets energy efficiency requirements for additions, which is why I'd rather settle the windows and insulation at the design stage than after.
How do I build a sunroom on my existing patio slab?
Start by checking whether it's a post-tension slab, one with steel cables pulled tight inside the concrete, before anyone cuts or breaks it. A Milpitas city handout advises that check because cutting one of those cables can be very dangerous and expensive to repair. When I come out, the slab is one of the first things I look at, since it decides whether the room can sit on it or needs a new foundation.
Other rooms to consider with a sunroom addition
Four season sunrooms
Pick this when you want the new room heated and cooled so you use it the same way you use your living room.
Three season sunrooms
A simpler room without heating or cooling, a good match when you mainly want light, shade and a place out of the bugs.
