Sunroom remodeling in Highland CA - a room that's comfortable to sit in again
Too hot in summer, foggy in winter or just sitting unused? We'll rework your sunroom so it becomes a room you actually use.

What's involved in remodeling a sunroom in Highland?
Sunroom remodeling in Highland, CA is reworking the room you already have, a sunroom or enclosed patio room with glass on much of its walls and roof, so it's comfortable for the way you want to use it. The main decision is how fully the room is enclosed, insulated, heated and cooled, and most of the other choices follow from that one.
Usually the room is there but nobody sits in it, because it bakes in the afternoon, feels cold all winter or the roof has seen better days. Some owners just want it usable in mild weather, and others want a true four-season room they can heat and cool. The price moves with the room's size, whether it'll be heated and cooled, and how much of the roof, floor and base we can keep. The schedule mostly depends on the plans and permit, and on whether your design needs an engineer's input. Highland's permit list covers renovations, roof repairs, and electrical and heating or cooling work, but it doesn't name sunrooms, so we check with the city for your address and prepare and file the plans and permit paperwork when your job calls for it. Your own figure comes from the estimate.
What happens when you call us about a sunroom remodel?
Call or send a message
Call (909) 737-1119 or use the form, and we'll set a time for me to come out to your house. Tell us a little about the room so I know what to look for.
I look over the room
I measure and check the house, the base and how you want to use the room, and I'll ask a lot of questions along the way. You get a written estimate that spells out what's in it and what isn't, so you know exactly what the price covers.
We handle plans and permits
Once you say go, we prepare the plans and file the paperwork with the office that covers your address, and Highland Building & Safety asks for 1 to 3 business days to check a submission, though most are processed the same day. If your design goes past the city's standard handouts, it needs more design or engineering from a design professional first, which adds time.
Our crew builds the room
Our own crew does the building, and we bring in licensed trade partners when the room needs wiring or heating and cooling. When it's finished, we walk the room with you.
How we handle a sunroom remodel
On a remodel I start with what's already there, the roof, the floor, the base it sits on and how it joins the house, and I tell you plainly what's worth keeping and what's holding the room back. A thin metal patio roof or a bare concrete slab is often why a room runs too hot or too cold, so if that's the trouble, we replace the roof or build an insulated floor over the slab before we get to the parts you'll notice. Then we rework the walls and windows to suit the room type you pick, tie everything into the house so water and drafts stay out, and plan how air moves through the room so it doesn't get stuffy or fog up. I care most about the parts you won't see once it's done, and if a spot is tricky I'd rather take the extra time to work it out than cover it up and hope.
Sometimes what you have isn't a room yet. If it's still an open covered patio, closing it in is a patio-to-sunroom conversion, and the same questions about the roof and floor apply. If you'd rather keep the breeze and just keep the bugs out, screen room installation may suit you better than a full remodel.
Get a written estimate for your sunroom remodel
We reply to every call and message within one business day to set a time for me to come out. The on-site estimate is free and comes with no obligation, and you'll get it in writing with everything the room would include.
Sunroom remodel questions from Highland owners
What's the difference between a three-season and a four-season sunroom?
A four-season room is generally heated and cooled and has all-weather windows, while a three-season room isn't heated or cooled and uses uninsulated windows or screens. Deciding whether you want heating and cooling comes first, because it sets the windows and the type of room, so it's one of the first things I'll ask you.
How much does it cost to remodel a sunroom in Highland, CA?
Adding a three-season sunroom onto an existing base in the San Bernardino area usually costs about $100 to $140 per square foot, installed, and larger rooms that need a foundation and heating and air conditioning sit toward the high end. Some local prices leave out insulation, extending heating or cooling, plumbing and permits, so ask what each quote covers. Our estimate lists what's in it and what isn't.
What causes sunroom windows to fog up in winter?
Moisture in the warm air inside condenses when it meets cold glass, and a tightly insulated room that's mostly windows is likely to do it in winter. The same room can get uncomfortably hot without air moving through it, which is why we plan for airflow as part of the remodel.
Is it better to insulate a sunroom during a remodel or later?
During the remodel, because insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is being built, and adding them later can often cost more. If you think you'll want to use the room through winter or summer heat, now is the time to decide.
What license should a sunroom contractor in California have?
In California, anyone who builds or alters a structure needs a license from the Contractors State License Board when the job needs a building permit, uses employees or costs $1,000 or more in labor and materials, and a sunroom remodel will almost always pass that mark. The class matters too, since the board's awning class covers awnings and patio covers but not patio enclosures, so ask which class a contractor holds. We're licensed and fully insured.
How do I take care of a sunroom after it's remodeled?
One sunroom maker's guide suggests checking the roof and gutters once a year and keeping the door and window tracks clean. The same guide says to keep the weep holes, the small drain openings, clear so water can drain out properly.
