Older homes and patios across San Bernardino
San Bernardino is down the Cajon Pass from us in Oak Hills, and the work there looks different from the High Desert. Most of the houses we walk are older single-story stucco homes on regular city lots, with a concrete patio out back and often an aluminum cover that's seen better days, though we get calls from newer tracts too. We also work right next door in Muscoy, and the same crew that builds rooms up in Apple Valley makes the drive down the hill.
Price moves with the size of the room, the glass and roof panels you pick, any wiring for lights and outlets, and whether the base needs work first. The schedule turns mostly on the city's permit and on getting materials in, and your estimate spells out what's in your number. On these older houses I check the slab and the house wall first, because a room is only as solid as what it sits on and what it ties into.
Our services in San Bernardino, CA
Most San Bernardino calls start with a slab out back that hardly gets used, and turning that patio into a sunroom is usually the most direct way to get a real room out of it. We check that the slab is level and sound first, and if it isn't, we tell you what has to change before we build on it.
A lot of older homes here still have the original aluminum cover, sagging in the middle or leaking where it meets the house. We take it down and put up a new cover tied properly into the wall and pitched so water runs off instead of back toward your house.
Some houses come with a room a past owner closed in years ago, now drafty, with cloudy windows and a roof that drips at the seams. We reseal it, swap out the worn panels and windows, and fix the drainage so the room is usable again without starting over.
On a smaller city lot, a screen room gets you an outdoor space that keeps bugs and leaves out without the cost of a fully glassed room. We build it on your existing slab or a new one, with screens set up so they're easy to clean and replace.
When you want a room you'll use like the rest of the house, with lights, outlets and a comfortable feel most of the year, that's a four season room with insulated walls and roof. We match the roof line and the stucco so it reads as part of the house, not something bolted on later.
Where there's no patio to build on, or the one there is too small, we pour a new base and add the room from the ground up. Older stucco needs care where the new roof meets it, so we tie in with flashing, a metal strip that keeps water out of that seam, before the walls go up.

How it works when you call us from San Bernardino
Call or send us a request
You call (760) 490-0317 or use the form, and we set a time for me to come out to your house in San Bernardino. Try to be home for that visit, because questions get answered best standing on the patio together.
I measure and check the base
I measure, look at the slab and the house wall, and keep answering questions until the plan makes sense to you. Then I write up an estimate that spells out what's in it and read it back with you, so you know exactly what you're paying for before we start.
We pull permits and build
Once you say yes, we line up the permit with the city and order materials, and that permit step is usually what sets the start date. Our installers build the room with me checking in along the way, and the city inspects at the points it calls for.
We walk the room together
When it's done, we walk the finished room with you, open every door and window and show you how the roof drains. Looking after it mostly means keeping the tracks and drains clear, and the room is backed by our satisfaction guarantee.
San Bernardino sunroom questions
Do I need a permit to build a sunroom in San Bernardino?
Usually, yes, because the city's Building and Safety Division issues permits for all structural, electrical and plumbing work with only a few minor exceptions, and a sunroom is structural work. The small exemptions the city lists cover things like detached sheds and low, detached decks that don't serve a door, not a room attached to your house. When we build the room, we pull the permit and set up the inspections for you.
Can a homeowner pull their own building permit in San Bernardino?
In most cases, yes, for work on a one or two-family house or a structure that goes with it, as long as you live there or plan to, show proof of residence and do the work yourself. You also sign a statement that you won't employ anyone in a way covered by California workers' comp laws. If we're the ones building it, the permit is ours to pull.
Does a contractor based outside San Bernardino need a city business license?
Yes, anyone doing business in San Bernardino needs a city registration certificate unless a state or federal law exempts them, and contractors based outside the city may be charged a flat rate for it. When a permit is issued, the contractor also shows proof of the right state license, a current city business license and, if they have employees, workers' comp insurance. We're licensed and insured, and it's fair to ask any contractor you're considering to show you theirs.
What affects the cost of a sunroom on an older San Bernardino house?
On older houses, the biggest swings come from what's already there: a cracked or uneven slab, an old patio cover that has to come down, and stucco that needs care where the new roof ties in. Wiring for lights and outlets adds to it, and so do plans the city asks for on a bigger room. I write each of those out on the estimate so you can see where the money goes.
Do I need a permit to fix up an old sunroom in San Bernardino?
Not for finish work alone, since the city doesn't require a building permit for painting, papering, tile, carpet, cabinets or countertops. Any electrical or plumbing done along with it still needs one. Replacing roof panels, walls or framing is structural work, so that part falls back under the permit rules above.
How do I know if my sunroom needs plans from an architect or engineer in San Bernardino?
The city settles that at plan review, because more complex projects need plans and specifications checked against code before a permit is issued, and in certain cases those plans have to come from a California registered architect or engineer. I can usually tell at the estimate whether your room is headed that way. If I don't know yet, I'll find out before I write anything up.
