Enclosed patio rooms in Bloomington CA - a room built on a slab that's ready for it
Got a concrete patio you barely use because of sun, dust or bugs? We close it in so it becomes a room you'll actually use.

Can my patio be turned into an enclosed room?
An enclosed patio room in Bloomington, CA is a three-season room built on the patio slab you already have, with windows, siding, a roof, fixtures and electrical access, so the space you barely use becomes a room you can sit in most of the year.
Most people who call us have a patio out back that's too sunny, dusty or buggy to enjoy, and they want a room they'll use. The price mostly moves with the size of the room, whether the slab needs work before anything goes on it, and how finished you want the inside. The schedule mostly turns on the permit review and inspections. If all you're after is keeping bugs out, a screen room may be enough. The estimate I write up after seeing your patio gives you the figure for your own house.

How we build an enclosed patio room
So much of this job depends on the slab, so I start there. I check how it sits against the yard and look for cracks or heaving before I price the room, because a slab that's too low or buckled has to be dealt with first. Once the plan and the permit are set, our crew frames the walls and roof, ties the room into the house, sets the windows and doors, and puts on the siding and roofing. We bring in electrical access for lights and outlets, clean up as we go and walk the finished room with you.
Some patios call for a different room or a smaller first step. If you want a glass roof and as much light as you can get, solarium installation may suit you better, though all that glass lets in more heat. If your budget or your slab isn't ready for a full room yet, patio cover installation gives you shade now, and the room can come later.
Why Bloomington homeowners call Brightspan for enclosed patio rooms
I come out and explain it
I do every estimate visit myself and go over each choice until you know what you're getting. Our own crew does the building, and I check the work as it goes.
In business since 2017
Before that, I spent years running another sunroom builder's jobs and learning the trade from the slab up. That's why I look at your concrete before we talk about windows.
Licensed and fully insured
Brightspan is licensed and fully insured, so you're covered while our crew works at your house. We stand behind the room with one promise, satisfaction guaranteed on every job.
Room placed inside your setbacks
County rules say building setbacks have to be kept whether a permit is needed or not, so even a small room has limits on where it can sit. We lay out the room with those lines in mind before you settle on a size.
The slab decides most of this job, so start with a look at yours. Have the patio's size, a few photos of the slab and any cracks, and your address ready when you call or send us a message.

We take care of the permit
We check whether the County or your city handles your address and do the permit paperwork. The County's process runs through plan review, the permit, inspections as the work goes and final approval with a Certificate of Occupancy, so we build those steps into your schedule from the start.
Our crew builds the room
Our crew builds while I keep an eye on each stage, and the inspector checks the work along the way. Once final approval comes through, the room is yours to use.
Enclosed patio room questions in Bloomington
Is my patio slab ready for an enclosed patio room?
It usually is if it sits higher than the yard around it and has nothing worse than hairline cracks. One enclosure maker's guide says the foundation must sit above the surrounding ground, because the window tracks have weep holes, small drain openings, and standing water can get into the room. The same guide accepts hairline cracks but says large buckling needs repair first, so if your slab sits level with the yard or has heaved, that fix goes into the plan and the price.
Do I need a permit for an enclosed patio in Bloomington, CA?
Plan on one, because San Bernardino County Building and Safety issues permits for enclosed patios and patio covers, and you get it from that office or the County's EZ Online Permitting site before work starts. The County also requires a Residential Accessory permit with approved plans for accessory structures over 120 square feet, so a larger room goes through plan review first. If you're not sure which permit fits your address, ask County Building and Safety at (909) 387-8311.
How much does an enclosed patio room cost in Bloomington?
A three-season room on an existing base, with labor included, usually costs about $100 to $140 per square foot in San Bernardino. That usual price doesn't cover insulation, extending heating or cooling, plumbing or pulling permits, so each of those adds to the total, and so does any slab repair. Your estimate gives you the price for your own patio.
Should I get an enclosed patio room or a four season sunroom?
Go with an enclosed patio room if you'll use it in spring, fall and on mild evenings, and pick a four season sunroom if you want it to work year round as part of the house. An enclosed patio room keeps out sun, wind and bugs, but it isn't built to be heated and cooled like your living room. If you're torn, I'll lay out both when I see your patio.
How do I take care of an enclosed patio room once it's built?
One sunroom maker's guide suggests checking the roof and gutters once a year, keeping the door and window tracks clean and keeping the weep holes clear so water drains. It also recommends pure silicone spray on doors and windows, because oil-based lubricants attract dirt.
What causes fog on the inside of sunroom windows?
Fog on the inside of the glass comes from too much moisture in the room, according to one sunroom maker's guide. It shows up most often when the seasons change. If it keeps coming back, mention it when you call and we'll talk it through.
