Patio-to-sunroom conversion in Bloomington CA - a room you'll actually use
Your patio sits empty most of the year. We close it in with windows or screens and build a room you'll use.
What does it take to turn my patio into a sunroom?
A patio-to-sunroom conversion in Bloomington, CA encloses the patio you already have with windows or screens, often on your existing slab and under your existing roof structure. You end up with a real room, left unheated or heated and cooled.
Most people who call us have a slab and a cover out back that only gets used a few weekends a year, and they want a room they'll sit in. The biggest choice is three-season or four-season, because a larger room with a foundation, heating and air conditioning sits at the high end of local prices. The price usually comes down when the room is small, sits on the slab you have, uses lightweight windows or screens, skips heating and cooling and keeps the roof structure that's already there. The schedule turns mostly on the permit, the county's inspections and how much the room needs. I'll go over all of it at your house and write up an estimate for the room we settle on.

How we handle a patio-to-sunroom conversion
I start by measuring how far your slab runs past the house wall, because when it sticks out 4 inches or more, walls set in line with the house leave a ledge that lets water in and isn't safe to leave. We plan the new walls around that edge so no ledge is left outside to catch water. Then we check whether the roof structure over the patio can carry the room or needs to be built new. Our crew frames the walls, sets the windows or screens you picked and closes in the roof, with any insulation you chose going in while the walls are still open. We finish with the doors and trim and clean up so the room's ready to furnish.
Not every job starts from a slab. If your outdoor space is a wood deck, a deck-to-sunroom conversion follows the same thinking on a different base. If you want the room comfortable in July and January alike, we'd steer you toward one of our all season rooms.

The owner does your estimate
I come out to every estimate myself, and our own crew builds the room while I check the work as it goes. You talk to the person who answers for the job, not a salesperson who hands it off.
In business since 2017
I learned this trade running another builder's jobs before starting this business in Bloomington in 2017. Many of the houses we see around here already have a slab and a patio cover out back, which is often a good start for this job.
Licensed and fully insured
We're licensed and fully insured. Enclosing a patio pulls in framing, glass, roofing and often wiring, and state law treats work on a room for people that uses two or more unrelated trades as general building work, so it's fair to ask anyone you're comparing how they're licensed.
Every choice explained before building
I'd rather spend extra time on your questions at the start than have you wonder later why something was built the way it was. That's how you end up with the room you wanted, and it's why we offer satisfaction guaranteed on every job.
Most of what matters on this job gets decided before anything is built. Have a few photos of your patio, rough measurements and an idea of three-season or four-season ready, then call (909) 275-7071 or send us a message.

What happens after you call about a patio sunroom in Bloomington?
Tell us about your patio
Call (909) 275-7071 or use the form and tell us how you'd like to use the space. Photos and rough measurements help me come out prepared.
I look at the patio
I come out myself, look at the slab and where the room would join the house, and we talk through how you'll use the space. Then I write up an estimate for the room we land on, so you know what you'd be getting before anything's built.
We line up the permit
Before work starts we confirm whether the county or your city handles your address and take care of the permit paperwork with that office. The county asks for permits in hand before work begins, so nothing gets built ahead of them.
Our crew builds the room
Our crew does the building while I keep an eye on each stage. The county generally wants an inspection before finished work gets covered up, so the schedule has inspection stops built in.
Patio sunroom questions from Bloomington
How much does it cost to turn a patio into a sunroom near Bloomington, CA?
A sunroom in the San Bernardino area usually costs about $100 to $190 per square foot. One local cost guide's figure covers labor, standard-grade windows, siding, roofing, fixtures and electrical access, but not insulation, extending your heating or cooling, plumbing or permits. When you compare estimates, ask what each one includes.
Do I need a permit to enclose my patio in Bloomington?
Usually, yes, because the county's permit list names enclosed patios, patio covers and additions, and permits come from the county's Building and Safety office or its EZ Online Permitting website. Any electrical, plumbing or heating and cooling work needs its own county permits too. Your zoning district also sets how far the room has to stay from the front, side and rear property lines, whether a permit's needed or not.
Is a three-season or four-season sunroom better for year-round use?
A four-season room is the one built for year-round use, because it's heated and cooled and has all-weather windows. A three-season room has no heating or cooling and uses uninsulated windows or screens, so it costs less but runs hot or cold with the weather. If you picture using it every month, I'd go four-season, and if it's for mild mornings and evenings, three-season is money honestly saved.
Can I add insulation to a sunroom after it's built?
You can, but insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is being built, and adding them later can often cost more. That's why I like to settle the insulation question in the first plan, even if you're leaning toward a lighter room.
What causes a damp spot on a sunroom floor built on a patio slab?
It's often water soaked into the concrete outside the room, when the slab is bigger than the room. In that case flashing to control water may not be practical, so the channel the walls sit in gets sealed straight to the slab, and moisture outside can show up as a passing damp spot inside, which one sunroom maker says isn't a structural issue. If your slab runs well past where the walls will go, bring it up at the estimate.
How do I take care of my sunroom roof?
One maker's homeowner guide suggests inspecting the sunroom roof and gutters once a year and keeping activity on the roof to what's needed. If something looks off, call (909) 275-7071 and we'll talk it through.
