Sunroom remodeling in Loma Linda CA - a forgotten room turned into one you use
Your sunroom runs hot, lets in drafts or just holds boxes. We fix the glass, insulation or frame so you actually use it.

Is my old sunroom worth remodeling?
Sunroom remodeling in Loma Linda reworks the glassed or screened room already on your house. Often that means turning a room with plain windows or screens into one that's heated, cooled and fitted with all weather windows, so it's comfortable for more of the year.
Most of the rooms we're called about were built as a simple enclosure and slowly became storage because nobody wanted to sit in them. The price moves with the room's size, whether you want it heated and cooled, how much of the frame and glass we can keep, and whether the base needs work, while the schedule turns on the permit review and on whether we're refitting the room or rebuilding it. If you already know you want it heated and cooled all year, our four season sunrooms page covers that build in more detail, and the written estimate gives you the plan and the figure for your own room.
What our sunroom remodeling includes
We start with what's there, the base, the frame, the roof and the glass, and I'll tell you plainly whether new glass and insulation will fix it or a rebuild makes more sense. Then we settle what the room is going to be, a simpler enclosure or a heated and cooled room, because that choice decides the windows, the insulation and the heating and cooling. If the floor has to be cut for a footing or a line, we check first whether it's a post-tension slab, one with steel cables under tension inside it, because cutting one of those cables is dangerous and expensive to repair. After that our crew takes out what's failing, repairs or replaces the framing, puts in the new windows and insulation, finishes the inside and cleans up. I'd rather tell you on the first visit that your base won't hold what you want than build a room that gives you trouble later.
Sometimes the right answer isn't a full enclosure. If you'd rather have the breeze back, we can take out tired glass panels and set you up with a proper screened room through our screen room installation work. And if your sunroom is really a covered slab with panels hung around it, the job is closer to a patio-to-sunroom conversion, where we build the room from the base up.
Sunroom remodeling rules and conditions in Loma Linda
Loma Linda's Building and Safety Division plan-checks all proposed construction, alterations to existing buildings included, before it issues building, plumbing, electrical and mechanical permits, so expect a remodel that changes the glass, framing or wiring to go through that review. When yours needs a permit, we draw up the plans and file them for you. The city also keeps fire hazard severity zone maps marking Moderate, High and Very High zones, and related building standards apply inside them. If your parcel falls in more than one zone, the city applies the highest one to the whole lot, and the City Clerk's office has the map on request. We look up your zone before we draw the plans, since it decides which of those standards apply to your room.
California's Energy Code sets efficiency requirements for additions and alterations to existing buildings, so new windows and insulation in a remodel have to meet it, and we choose them with that in mind. Most of what we're asked to redo is an older patio enclosure or screen room that was never meant to be lived in, and we see the same kind of rooms on jobs in Redlands and Yucaipa.
How a sunroom remodel works
Call or send the form
Call (909) 515-5048 or use the form and tell us a little about the room. We'll set a time for me to come out.
I look at the room myself
I measure, check the slab or deck and the frame, and ask what you want the room for, because that decides whether it needs heating and cooling. You get a clear recommendation and a written estimate that spells out the scope and the price.
We handle permits and build
We take care of the permit paperwork with the city's building office, then our crew builds in order so each stage is ready when the inspector comes. Nothing has to be torn back open just to show the inspector what's inside a wall.
Walk the finished room together
When the work's done, I walk the room with you and go over the windows, doors and anything else you want to check. If something isn't right, that's when you tell me.

Find out whether your sunroom needs a refit or a rebuild
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 the room, and the estimate at your property is free. There's no pressure and no obligation to go ahead.
Questions before you book a sunroom remodel
What is the difference between a three season and a four season sunroom?
A four season room is heated, cooled and fitted with all weather windows, while a three season room isn't heated or cooled and uses plain windows or screens. If the room is open to the house and built to be heated or cooled, a sunroom industry specification treats it as living space, so its windows have to meet requirements for air leaks, water leaks and thermal performance. The right choice comes down to how you plan to use the room.
How much does a sunroom remodel cost near Loma Linda?
As a guide, adding a three-season sunroom to an existing base, labor included, usually costs about $100 to $140 per square foot in the San Bernardino area. Larger rooms that need a foundation and heating and air conditioning land at the higher end of local prices, and a remodel moves with how much of the old room we can keep. The written estimate gives you the number for your room.
How do I keep a glass sunroom from getting too hot?
Start with the glass, because one glazing maker says low solar gain glass carries a thin clear coating that reflects part of the sun's energy while keeping the natural light. The same maker's advice is to keep sun off the glass with outside shade like a pergola, an overhang or louvers, so it's worth planning the shade along with the windows.
How do I add insulation to an old sunroom?
Usually by opening up the walls, floor and roof during the remodel and pairing the insulation with highly insulated windows. Those features are much easier to put in while the room is being built or rebuilt, and adding them later often costs more, so we settle them at the start.
What kind of contractor license does a sunroom remodel need in California?
In California, a general building contractor takes on work that needs two or more unrelated trades, and a glazing contractor installs glass, frames, panels, sashes and doors in any structure. A remodel that touches framing, insulation and glass usually involves more than one trade, so ask any contractor which classification they hold and check it with the state licensing board.
What should a sunroom remodel quote in Loma Linda include?
Ask whether the price covers insulation, extended heating or cooling, plumbing and permits, since at least one local price guide leaves those out of its per-foot figures. A quote that names each of them makes it easier to compare contractors fairly.
Why Loma Linda homeowners call Loma Linda Sunrooms & Patios for a remodel
I come out to every job
I measure and look at the room myself before you get a number, and our own crew does the building. The person who sized up your room is the one you talk to while it's being built.
In business since 2021
I built patio covers and sunrooms when I was younger and came back to the trade to start this business five years ago. Turning old patios, decks and unused rooms into space people use is what we're best known for.
Licensed and insured on every job
We're fully licensed and insured. A remodel opens up framing, glass and often wiring on your house, so that coverage matters while the room is apart.
Plans ready for Loma Linda's review
We draw the plans with your parcel's fire zone already checked, so they go to the city's plan check complete. That keeps a missing detail from sending them back and pushing your start.
On a remodel, the choices that cost the most to change later are made before any glass comes out, so that's where I'd start. Book a visit and I'll come take a look.
Other work that ties into a remodel
Screen room installation
A good fit if you'd rather have fresh air and shade than a closed-in room with heating and cooling.
Patio-to-sunroom conversion
For a covered slab with panels around it that needs a real room built from the base up.
Book a look at your old sunroom
We take calls until 10 PM on weekdays and 11 PM on weekends, so call (909) 515-5048 with the room's size, what it is now and whether you want it heated and cooled.
