Custom sunrooms in Bloomington CA - a room built around how you'll use it
A patio or deck that sits empty most of the year can become a sunroom sized, glazed and closed in for the way you live.

What goes into a custom sunroom in Bloomington?
A custom sunroom in Bloomington, CA is a room we add to your house and build around how you'll use it. It can be anything from a fully enclosed room that's heated and cooled to a patio closed in with screens only.
Most people who call us have a patio that bakes in the afternoon, a deck nobody sits on or an old sunroom that never got used much, and if yours is that old room, our sunroom remodeling work may be the better place to start. The price moves mostly with size, whether the room needs its own foundation and whether you want heating and air conditioning, because the bigger, fully closed rooms with all three sit at the top end. The schedule mostly turns on the permit and on whether an existing deck needs checking before we build on it. Once I've seen your house, I'll write up an estimate with a figure for your own room.

How we build a custom sunroom
I start by asking how you'll use the room through the year, because that answer decides the size, the glass and how closed in the room should be. If you want it comfortable in July and in January, that points to a four-season room, with all-weather windows and heating and cooling. A three-season room has uninsulated windows or screens and no heating or cooling, and a screened porch has no windows at all, so neither one will hold a steady temperature. Once you've picked, we settle the insulation in the walls, floor and roof and how well insulated the windows are before anything gets built, since adding those later can often cost more than doing it during the build. From there our crew gets the base ready, frames the room, ties it into the house where the two meet, sets the roof and glass, and cleans up when we're done.
If you're starting from bare ground and want the whole job handled, our sunroom construction work covers the build from the slab up. If you already have a sunroom that's worth keeping but runs too hot or looks worn, sunroom remodeling lets us rework what's there.
Why Bloomington homeowners call Brightspan for a custom sunroom

Running sunroom jobs since 2017
I spent years running another sunroom builder's jobs before I started this business in Bloomington in 2017. I'll tell you straight out when a choice isn't a good idea for your house, and I'm happy to explain it twice.
Licensed and fully insured, ask us
We're licensed and fully insured. The Contractors State License Board licenses California's builders, so you can ask any contractor which license they hold and check it with the board.
Setbacks worked out before design
San Bernardino County sets how close any structure can sit to your front, side and rear lines based on your zoning, and those setbacks apply whether or not a permit is needed. We factor them into the room's size on the first visit, so you aren't planning a room that won't fit the lot.
What matters most on this job is getting the type and the insulation right before anything gets built. Call (909) 275-7071 or send us a few details with the type you have in mind, a rough size and whether it would sit on a deck.

What happens after you call about a custom sunroom?
Call or send us a message
Call (909) 275-7071 or use the form, and tell us the type of room you're picturing, a rough size and whether it would sit on a deck. We'll set a time for me to come by.
I look at your house
I look at the slab or deck and where the room would join the house, and we talk through how you'll use the space. Then I write up an estimate that lays out the size, glass, insulation and price for your room.
We handle the permit paperwork
We confirm whether the county or your city handles your address and take care of the permit paperwork when the job calls for one. The county reviews the plans before building starts, so that review sets when we can begin.
Our crew builds, I check
Our own crew builds the room while I keep an eye on each stage. The county generally wants an inspection before finished work gets covered up, so we plan the build around those visits.
Custom sunroom questions
How much does a custom sunroom cost near Bloomington, CA?
A sunroom in the San Bernardino area usually costs about $16,000 to $115,000 per project. That's the area's going rate, not our price, and where yours lands depends mostly on the size, the foundation and the heating and cooling. I'll put a figure on your own room at the estimate.
Can a sunroom be built on my existing deck?
Sometimes, if the deck is strong enough to carry it. One maker's guide notes that many decks aren't built for that extra weight, so it says a local engineer or a qualified contractor should look at the deck first. I'll look at yours on the first visit and tell you plainly if it isn't a good idea.
Do I need a permit for a sunroom in Bloomington, CA?
Check with San Bernardino County's Building and Safety office, which issues permits for additions like a room addition. Its list names enclosed patios but doesn't name sunrooms, so ask about your project and confirm that office handles your address.
How much can a sunroom contractor ask for up front in California?
A contractor can't ask for a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. The state licensing board also says later payments have to be listed in the contract and match work done or materials delivered, so read that part before you sign.
What is the difference between a sunroom, a solarium and a conservatory?
Solarium and conservatory are other names for a four-season room, the kind that's fully glassed and heated and cooled, and an enclosed patio generally counts as a three-season room. The names matter less than how closed in you want it, so tell me how you'll use the space and we'll start there.
How do I take care of a sunroom so it lasts?
One maker's care guide suggests checking the roof and gutters once a year and keeping the weep holes, the small drain slots along the bottom of the frame, clear so water can get out. The same guide suggests keeping door and window tracks clean, using a pure silicone spray so they slide smoothly, and staying off the roof unless you have to be up there.
