What does it take to build a sunroom in Colton?
Sunroom construction in Colton means building an enclosed room onto your house. It can be anything from a screened porch with screens only to a four-season room that's heated and cooled, so you get real use out of the space behind your house.
Most of our calls come from people with a patio, a deck or an older room that isn't getting much use, and the first question is how close the new room should feel to the rest of your house. The price moves with that room type, the size, whether you want heating and cooling, how much insulation goes in, and whether your slab or deck can carry the room or needs a new foundation. The schedule turns on how much design work your room needs and on the city's plan review and inspections. When I come out, you get a written estimate built on your own room, so you aren't guessing from someone else's numbers.
How we handle sunroom construction, start to finish
How the new roof ties into your house is one of the first things I look at, and we settle it before the rest of the design is drawn, because one sunroom maker's installer training says the fascia board, the trim board along your roof edge, is rarely able to hold the added load of an attached roof. Next we pick the room type and the insulation together, since insulated windows, walls, floor and roof go in much more easily while the room is being built and adding them later can often cost more. Then our crew preps the base, sets the frame and roof, puts in the windows or screens and doors, and finishes the trim and cleanup.
Not every project needs a new room. If you already have one that leaks, bakes or just sits empty, sunroom remodeling may make more sense than starting over, and if you mostly want shade and fresh air without the bugs, screen room installation is the simpler job.
Three-season room
A three-season room usually has no heating or cooling and uses uninsulated windows or screens, so it stays close to the weather outside. It suits you if you want a sheltered spot for mild mornings and evenings and don't need it to feel like part of the house.
Four-season room
A four-season room has all-weather windows and is heated and cooled, so it feels much like the rest of your house. It suits you if you want to use the room every month of the year, as a family room, an office or a place to eat.
Sunroom construction in Colton and the cities around it
In Colton, plan check, permits and inspections for building construction go through the city's Building and Safety office, which checks the work against the state building codes and the city's own ordinances. That means a room attached to your house gets reviewed on paper before we build and looked at again on site while we do. When your project needs a permit, we confirm which building office covers your address, prepare the plans, handle the paperwork and set up the inspections, so you don't have to learn the process to get your room built.
We're based in Colton and work in cities all around it, and we see a lot of the same houses on jobs in San Bernardino and Redlands, often a single-story home with an older concrete patio out back. Before a room goes on a slab like that, I check whether it can carry the weight or needs a new footing, and if your city isn't listed on our site, just ask.

Before I draw a room here, I go through the city's plan check requirements for room additions and its patio cover standard, both posted on the city's building forms page. You can read them too before plans are drawn, so nothing on your plans comes as a surprise.

Frequently asked questions
How much does a sunroom cost near Colton?
A three-season sunroom added to an existing base in nearby San Bernardino usually costs about $100 to $140 per square foot, labor included. That's what the work goes for in the area, not our price, and larger rooms that need a foundation plus heating and air conditioning cost more. One San Bernardino price covers windows, siding, roofing, fixtures and electrical access but leaves out insulation, extending heating or cooling, plumbing and pulling permits, so ask what any number includes before you compare.
Should I build a three-season or four-season sunroom in Colton?
If you want to use the room through the summer heat and on cold evenings, I'd lean toward a four-season room, because a three-season room usually has no heating or cooling and stays close to the weather outside. A three-season room makes sense when you mainly want a sheltered spot on mild days. Whichever you pick, settle it before the plans are drawn, since that's when the insulation decision gets made.
What license does a sunroom builder need in California?
The state license board says a "B" General Building contractor may contract for a project that includes roofing, such as a room addition, while a roofing job contracted on its own goes to a C-39 roofing contractor. The board also has a glazing license class that covers installing glass, frames, panels, sashes and doors, so it's fair to ask who will handle the glass on your room.
What is the best way to pick windows for a sunroom in Colton?
Compare the solar heat gain coefficient, the rating that shows how well a window resists the sun's heat, because a lower rating helps keep the room cooler in summer. Ask for that rating on every window you're quoted, since in a room that's mostly glass it makes a big difference on a July afternoon.
Does a heated sunroom count as part of the house?
An industry sunroom specification treats a room with enclosed walls that's heated or cooled and open to the house as habitable, conditioned space, the kind of room you live in. Under that specification, its windows meet requirements for keeping out air and water and for thermal performance.
How do I take care of a sunroom roof?
One sunroom company's guide suggests an inspection of the roof and gutters every year and staying off the sunroom roof unless there's a real need. Keeping the gutters clear of leaves before the rains come helps the water run off the way it was meant to.
