What goes into adding a sunroom to a Redlands house?
A sunroom addition in Redlands is a glass-walled room we build onto your house, on a slab, a deck or a new foundation, so you get usable space with daylight and a view of the yard.
Most people who call us have a covered patio they'd like to close in or a bare slab off the back, and they want a room they'll really use. The biggest thing that moves the price is whether you want a heated and cooled room for every month or a lighter one for mild weather. After that comes the size, whether we can build on what's already there or need a new foundation, and how much glass goes in the roof. The schedule mostly turns on what the base and the house wall turn out to need and on the permit paperwork, and the written estimate after my visit spells out what's in your price and what isn't.
How do you know it's time to add a sunroom?
Patio sits empty all summer
You've got a covered patio, but nobody's out there between June and September, or after dark when the bugs come out. That usually means shade alone isn't enough, and every year you wait is another season of paying for space you don't use.
The house feels a room short
The home office lives on the dining table, or the kids have nowhere to spread out. A sunroom off the back is often the simplest way to add living space, and putting it off usually just means more furniture squeezed into the rooms you have.
Old enclosure that leaks or sticks
You see water stains at the house wall, sliders that drag, or a roof that's started to dip. That usually points to a weak tie-in or a base that wasn't built to carry the room, and the damage spreads into the house the longer it goes.
How we build a sunroom addition
The first thing I ask is whether you want a room you'll use every month of the year or a lighter space for mild weather, because that answer sets the windows and most of the budget. Then I look at what will hold the room up, meaning the slab, the deck or the ground where a new foundation would go, and the house wall the roof ties into, and I'll tell you plainly if something needs a closer look. We plan the roof with summer heat in mind, since in our summers the roof is where most of the heat comes in. Once you've signed off, our crew builds the base, frames the room, ties the roof into the house so water runs off instead of in, sets the windows, seals the door and window tracks and cleans up.
Four season room for daily use
This suits you if the room will be a den, an office or a place to eat that you'll use every month. It costs more up front, and if you're on the fence I'd lean this way, because a room you can't sit in during August usually ends up as storage.
Three season room for mild weather
This suits you if you want a bright spot for spring and fall and mild evenings and don't need it heated or cooled. It costs less and is a good fit when the budget is tight or the house already has the living space you need.

We get back to you within one business day, and I'm usually the one who calls. The estimate is free, done at your house and carries no obligation, and I'll come out to measure and talk through how you plan to use the room.
(909) 488-7044Planning a sunroom addition in Redlands near fire hazard areas
It's worth knowing early whether your lot sits in a fire hazard zone, because that belongs in the plan from the start, not halfway through the build. A local report on the new Cal Fire maps says southern and eastern Redlands, including San Timoteo Canyon, Live Oak Canyon and the Crafton Hills area, remain in the Very High fire hazard category, and newer zones now reach into North Redlands. If your address falls in one of them, bring it up at the first visit, since the permits the building office asks for on our jobs are ours to sort out. The questions below cover how to check your address.
We're based in Redlands and work in many of the cities around it in San Bernardino and Riverside counties. Sloped backyards and long afternoon sun on back patios come up on jobs in Mentone and Yucaipa as often as they do here, and we plan the base and the roof for them the same way.
What happens after you call about a sunroom addition?
Call or send the form
You call (909) 488-7044 or send the form, and we get back to you to set up a visit. I'm usually the one who answers the phone.
I measure and look closely
I come out to measure, check the base and the house wall, and ask how you plan to use the room. Have a sense of heated or unheated in mind, since that's where the plan starts.
Go over the written estimate
You get a written estimate that lists what's in it and what isn't, so you know what you're paying for before anything is built. We sort out the paperwork with the building office before the build begins.
Build, check in, walk through
Our crew lead runs the build day to day, and I stop by as it goes to check the parts that get covered up. When it's done, we walk the finished room together.
Frequently asked questions
What's the difference between a three season and a four season sunroom?
A four season room is generally heated and cooled with all-weather windows, while a three season room generally isn't and uses uninsulated windows or screens. The first is built to stay comfortable through every season, and the second works more like an enclosed porch. A heated and cooled room also falls under California's Energy Code, which sets energy requirements for additions to existing homes, so we plan its windows and insulation around it.
How much does a sunroom addition cost in Redlands?
A sunroom in the San Bernardino and Riverside area usually costs about $95 to $200 per square foot. Larger rooms that need a foundation and have heating and air conditioning sit toward the high end, and one San Bernardino estimate for a three season room on an existing base left out insulation, extending heating or cooling, plumbing and permits. Your written estimate from us lists what's in your price, so you can compare it fairly.
Who pulls the permits for a sunroom addition in California?
California's contractor board says a home improvement contract must state in writing who will get the necessary permits. Any home improvement job over $500 also needs a written contract with a completion date, and the down payment can't be more than $1,000 or 10 percent of the contract price, whichever is less. On our jobs, the contract says in writing that we're handling the permits the building office asks for, whether that office is a city or the county.
How do I check if my Redlands address is in a fire hazard zone?
You can look up your address on the fire department's interactive map, which shows the newly designated zones in North Redlands. Do it before you settle on a design, and if your lot comes back in a zone, tell me at the first visit so it's part of the plan.
What is the best way to make a sunroom comfortable year-round?
Decide how warm or cool you want the room before work starts, because insulated windows and wall, floor and roof insulation are much easier to put in during the build and can often cost more to add later. That's why we settle the room type at the first visit instead of after the frame is up.
What makes a room a sunroom instead of a regular addition?
One California city's building handout describes a sunroom as a one-story structure attached to the house with glass making up more than 40% of its outer walls and roof. That much glass is what gives the room its light, and it's also why the window and roof choices carry so much of how the room feels.
