Sunroom construction in Loma Linda CA - a room built right the first time
Have a covered patio or slab that sits empty most of the year? We'll turn it into a room you'll actually use.

What does it take to build a sunroom in Loma Linda?
Sunroom construction in Loma Linda means building an enclosed room with windows or screens onto your house. It can be anything from a heated and cooled four-season room to a screened porch, so you get space you can use when the yard is too hot or too buggy to enjoy.
Most people who call us have a covered patio, a slab or a deck they already like, and they want to use it in July and in January. The room type sets most of the budget, because a heated and cooled room on a real foundation costs more than a three-season room or a screened one, and size, glass and how the room ties into your roof move it from there. The schedule mostly turns on the city's plan check and inspections, and on whether there's structural work at the house. If your patio is already covered, a patio-to-sunroom conversion can often build on what's there, and the written estimate I give you after the visit puts your own room in numbers.
How we handle sunroom construction
I start by looking at what the room will sit on, because a slab or deck that can't carry walls and a roof is something you want to know before anything gets ordered. Then we settle the room type and the insulation with you, since insulated windows and insulation in the walls, floor and roof go in far easier during the build than after it. When the room ties into your roof or a bearing wall, I tell you up front what structural work that takes and how we'll handle it. From there our crew builds in order, footings or foundation first, then framing and the roof tie-in, then windows, insulation, wiring and finish, and we plan summer shade along with the glass.
Not every room has to start from scratch. If you already have a sunroom that leaks, runs hot or feels worn out, sunroom remodeling often costs less than tearing it down, and if you mostly want to sit outside without the bugs, screen room installation gets you there with a lighter build.
Sunroom construction rules and conditions in Loma Linda
In Loma Linda, the city's Building and Safety Division plan-checks all proposed construction projects, additions included, before it issues a building permit. It also inspects additions and structural alterations in the field and issues the electrical and mechanical permits. When your room needs a permit, we put the plans and paperwork together, file with the city and meet the inspector at each inspection. We also check whether your lot sits in one of the city's Moderate, High or Very High fire hazard zones on the updated CAL FIRE maps, because related building and fire safety requirements apply there, and when a parcel falls in more than one zone, the stricter one covers the whole lot.
We're based in Loma Linda and build in the cities around it. Most rooms here go behind single-story houses on an existing slab or covered patio, and the long, hot summers make the glass and shade plan as important as the framing. We see the same kind of yards and the same summer heat on jobs in Redlands and Yucaipa, and we build there the same way.
How a sunroom build works
Call or send the form
You reach us at (909) 515-5048 or through the form, and we set a time for me to come out. Let us know if you're starting from a slab, a deck or a covered patio.
I come out and measure
I come out myself to measure, look at the slab or deck and hear what you want the room for. You get a clear recommendation and a written estimate, so you know what the room involves and what it costs before you decide.
We file and build in order
We take care of the permit paperwork, then our crew builds stage by stage so each one is ready when the inspector comes. That way an inspection doesn't hold up the next step.
Walk the finished room together
When it's done, I walk the finished room with you. We go over how the windows, doors and shades work and anything you should keep an eye on.

Send the form and we'll reply within one business day to set up a visit. I come out myself to measure and look at what the room will sit on. The estimate is free and done at your property, with no pressure and no obligation.
Questions before you build a sunroom
How much does sunroom construction cost in Loma Linda?
In nearby Riverside, sunroom construction usually costs about $17,000 to $120,000 per project. Where you land mostly comes down to the room type and its size, as covered above. The written estimate from my visit gives you the number for your room.
What is the difference between a three-season and a four-season sunroom?
A four-season room is heated and cooled and has all-weather windows, while a three-season room has uninsulated windows or screens. One industry specification counts an enclosed room that's heated or cooled and open to the house as living space, with windows and doors that resist air and water leaks. If you want to sit in it on summer afternoons here, I'd go four-season.
How do I keep a sunroom from overheating in the summer?
Plan shade and airflow along with the glass. In one research study, a glassed-in room on a house cut winter heating needs but overheated badly in summer, and shades inside the room plus airing it out at night kept that down. We work out where the shades go and how the room vents before the windows are ordered.
Which direction should a sunroom face?
South gets the most winter heat, and the same study found that more glass compared with solid wall added to that benefit. That glass also brings in summer heat, so if your room faces south, I'd keep some solid wall and plan for shades from the start.
Who do I ask about permits for a sunroom in Loma Linda?
The city's Building and Safety Division plan-checks and permits the work, as described above. The Planning Division answers zoning, land use and permit questions and reviews residential projects, so it's a good place to ask about your own lot before we start.
How do I take care of a sunroom once it's built?
One maker's guide suggests checking the roof and gutters once a year, cleaning the door and window tracks and keeping the weep holes, the small openings that let water drain, clear. It also suggests a pure silicone spray for sticky doors and windows, since oil-based lubricants tend to pull in dirt.
Why Loma Linda homeowners call Loma Linda Sunrooms & Patios to build a sunroom
I look at every job myself
I come out to measure and check the slab or deck on every job, and our own crew does the building. Nothing gets lost between what we talked about at the estimate and what goes up.
A plain no on day one
I started this business in 2021 after years away from building, and I came back to do it properly or not at all. If your deck or slab can't hold the room you want, I'll tell you on the first visit and show you what will work.
Licensed, insured and clear on structure
We're fully licensed and insured. In California, a Class B general building license covers jobs that need two or more unrelated trades, while a remodeling contractor can't contract for changes to footings, foundations, bearing walls or roof structures. When a room ties into your house, ask any contractor which license they hold.
On a sunroom, the work that matters most is what you stop seeing once it's finished, the footing, the roof tie-in and the insulation. Book a visit and I'll tell you what your slab or deck can hold.
Other work that goes with a sunroom
Sunroom remodeling
For an existing sunroom that leaks, runs hot or no longer fits the way you use it.
Screen room installation
For a lighter, screened space when keeping bugs out matters more than heating and cooling.
Tell us the sunroom you have in mind
Call (909) 515-5048 or send the form with the room type you want, a rough size and whether your lot sits in a fire hazard zone, so I show up ready to give you a real answer.
