Barstow homes and the patios behind them
Barstow homes run from older single-story stucco houses to newer tract homes on the edges of the city, and most have a concrete patio or a wood deck out back that takes the full afternoon sun. The calls we get from here sound a lot like the ones from Lucerne Valley and Piñon Hills. People want to close in that patio or deck, or fix up an older room so they can use it more of the year.
Plenty of those patios were poured to hold a light cover and some chairs, not glass walls and a roof, so what your new room will sit on is usually the first thing we talk about here.

Our services in Barstow, CA
- Four season sunrooms
Barstow summers run hot and winter nights get cold, so a room you want to use in both July and January needs insulated walls and roof, the right glass and a plan for heating and cooling. We settle all of that with you before anything is ordered, because changing it after the walls go up costs more.
- Patio-to-sunroom conversion
A lot of homes here already have a concrete patio out back, and closing it in is often the most direct way to add a room. We check the slab's thickness, edges and slope first, since a slab poured for a light cover may need new footings under the walls.
- Deck-to-sunroom conversion
Wood decks out here take a beating from sun and dry wind, and the posts and beams under them were sized for people and chairs, not glass walls and a roof. For a deck-to-sunroom conversion we open up the framing to see what's there, then reinforce it or rebuild the base before the room goes on.
- Patio cover installation
When you mainly want shade on a patio that faces the afternoon sun, a solid or insulated patio cover is often a better buy than a full room. We set the posts on proper footings and tie the cover to the house and posts with the wind on open desert lots in mind.
- Sunroom remodeling
Older sunrooms here often have single-pane glass and thin roof panels that turn them into an oven by midday. We swap in better glass, roof panels and insulation so the room you already have becomes one you'll actually sit in.
- Patio enclosures
Blowing dust and sand are a big reason people here close in a patio, so they can sit outside without sweeping it every morning. We pay close attention to the seals at the base and around each window, since that's where dust finds its way in.
What Barstow's desert ground asks of a sunroom
Sandy and caliche soils like Barstow's are less able to carry a building than soil in the wetter, more built-up parts of California. Caliche is a hard, cement-like layer under the sand, and the ground can change from one corner of a yard to another. So I look at the ground as well as the slab, and if it won't carry walls and a roof as it is, new footings go into the plan from the start rather than turning up halfway through the job.
The other thing a Barstow room has to handle is the sun. A west-facing room with the wrong glass can get hotter than the yard by mid-afternoon and then lose its heat fast on a cold desert night, so we settle glass, roof panels, insulation and how you'll heat and cool the room with you before any of it is ordered.

Sunroom and patio enclosure ideas
Barstow sunroom questions answered
Do I need a permit to build a sunroom in Barstow?
The city's Building and Safety Division issues building permits in Barstow, so it's the office that tells us what your sunroom needs. Its process generally runs through permit processing, plan review and inspections. We check with that office for your address and take care of the permit paperwork the job needs.
Which building code does a sunroom in Barstow have to meet?
Plans submitted to the city for review have to be designed under the 2022 California Building Codes. The Building and Safety Division enforces those state codes along with the city's own Municipal Code on homes and commercial buildings, so a room added to your house is held to both.
How do I submit sunroom permit plans to the City of Barstow?
Barstow asks for application forms and plans in hard copy with original, wet signatures, and a Waste Management Plan Application goes in with each applicable building permit application. The forms are on the city's building forms page, and city offices are open Monday through Thursday and closed Fridays, which matters when paper has to go in by hand. We put that package together as part of the permit paperwork.
What causes flash floods in Barstow, and can they affect a sunroom?
Flash floods are common in Barstow because the desert soil can't soak up even a moderate rain quickly, and the city says flooding happens a few times each year. For a sunroom, that means we look at where water runs across your lot and plan the base and floor edge so runoff moves away from the room instead of pooling against it.
How much does a sunroom cost in Barstow, CA?
A Barstow sunroom's price comes down mostly to its size, whether it's a three season or four season room, the glass and roof panels you pick and how much work the base needs on this sandy ground. Heating and cooling, electrical work and rebuilding an old deck or slab can move it a lot, while the schedule usually turns on permit review and when the glass and panels arrive. I'll give you your own figure once I've measured and looked at what the room will sit on.
Is there a Barstow business license for out-of-town contractors?
Yes, the City of Barstow offers a separate Business License Application for out-of-town businesses, apart from the one for businesses in the city. It's a fair question to put to any contractor coming in from another city, us included, since we're based in Adelanto. We're licensed and fully insured, and our work is backed by our satisfaction guarantee.
