Vinyl sunrooms in Loma Linda CA - a bright room built for how you'll use it
Your patio gets too much sun and dust to use most days. We enclose it in vinyl and glass so it becomes a real room.

What goes into a vinyl sunroom in Loma Linda?
A vinyl sunroom in Loma Linda is a room of windows framed in vinyl, a PVC plastic, built on the slab, deck or foundation you already have. You get an enclosed space you can heat and cool or leave to the season, depending on the room type you pick.
Most people who call us have a covered patio, a slab or a deck they hardly use because it's too hot or too dusty, and a vinyl room is often the simplest way to make it space you'd actually sit in, which is really a patio-to-sunroom conversion at heart. The price moves with the size of the room, the room type, how much insulation and glass you put in, and whether your base can carry the room or needs a new foundation, so a large room with a new foundation and heating and cooling sits at the top end. The schedule mostly turns on whether the base needs work first and how long the city takes to review the plans. Once I've seen your house, I'll give you a written estimate with your own figure.
How we build a vinyl sunroom
I start with the base you've got, because a vinyl sunroom sits on an existing structure and I'd rather tell you no on the first visit than build a room your slab or deck can't hold. Then we settle the room type, the windows and the insulation in the walls, floor and roof before anything gets built, since those go in much more easily during construction and adding them later often costs more. Our crew preps the base, sets the vinyl frame and window walls, puts the roof on, finishes the trim and cleans up. We follow the room maker's installation instructions as written the whole way, because many makers tie their warranty to a proper install, and one maker gives owners who install or arrange their own installation no labor warranty at all.
If you want the room to read as a true part of the house, with its own foundation and roofline, that's one of our sunroom additions. If you plan to use it every month of the year, we can build the vinyl room as one of our four season sunrooms and size the heating and cooling to match.
Building a vinyl sunroom in Loma Linda
Loma Linda's building office plan-checks every proposed construction project, additions to existing homes included, before it issues a building permit, so your sunroom starts with drawn plans, and we put those together for you. If your lot sits inside one of the city's mapped fire hazard zones, the room falls under the building standards and fire safety requirements that come with that zone. The city doesn't send letters telling homeowners whether they're in or near a High Fire Severity Zone, so check your address on the city's fire map before we design. The walls, windows and doors also have to meet California's efficiency standards for the climate zone your house sits in, which is one more reason we settle insulation and glass with you up front.
Most of what we enclose here is a covered patio on a slab or an older deck, and the afternoon sun is usually why nobody sits out there. We're based in Loma Linda and build in the cities around it, and we see the same patios and decks on jobs in Redlands and Riverside.
How a vinyl sunroom job goes
Call and set a visit
You call or send the form, and we set a time for me to come out. Have a rough idea of what you'll use the room for, because that decides most of what follows.
Measure and check the base
I measure, look over the slab or deck and listen to what you want from the room. You get a clear recommendation on room type, glass and insulation, plus a written estimate, so you know what's in the price before you decide anything.
Permit first, then the build
We take care of the permit paperwork, and building starts once the city has checked the plans and issued the permit. Our crew builds in order so each stage is ready when the inspector comes.
Walk the finished room
When it's done, I walk the room with you and open every door and window together. Anything you want to ask about, you ask me right there.

Get a written estimate for your vinyl sunroom
Send the form and we'll reply within one business day to set a time for me to come out. I'll measure, look at your slab or deck and give you a recommendation and a written estimate. The estimate is free and done at your property, with no pressure and no obligation.
Questions before you book a vinyl sunroom
How much does a vinyl sunroom cost near Loma Linda?
A sunroom in nearby San Bernardino usually costs about $100 to $190 per square foot, which is the going rate in the area and not our price. Where your room lands in that range depends on what I find at your house, and the written estimate gives you your own figure.
What should a sunroom estimate in Loma Linda include?
Ask whether each estimate includes insulation, heating and cooling, plumbing and the permit, because one San Bernardino price for a three-season room left all four out. Go through each quote line by line before you compare totals, or the cheapest one may just be the emptiest.
What is the difference between a three-season and four-season sunroom?
A four-season room is generally fully enclosed, heated and cooled, with all-weather windows, while a three-season room generally isn't heated or cooled. A screened porch has screens only, so the type you pick decides whether you get glass and temperature control at all. If you plan to sit in it on summer afternoons here, I'd go four-season.
Is vinyl a good frame material for a sunroom?
Yes, for comfort it's a good choice. Vinyl frames conduct heat much less than metal frames and about as much as wood, so less heat moves through the frame and the room stays more comfortable.
What is the best glass for a sunroom in a sunny place like Loma Linda?
Glass with a selective low-E coating, a thin layer that controls the sun's heat while staying clear, is usually the best fit. It matters most in sunny areas where you don't want tinted or mirrored glass blocking the view you built the room for.
How do I take care of a vinyl sunroom?
One maker's guide suggests checking the roof and gutters once a year and keeping the door and window tracks clean, inside and out. It also suggests a pure silicone spray on doors and windows instead of an oil-based lubricant.
