What goes into a custom sunroom in Colton?
A custom sunroom in Colton, CA is a room built onto your house over a patio or porch, with its wall openings filled with glass or clear plastic, and sized and finished around the way you'll use it.
Most people who call me have a patio, a deck or an older room that isn't getting much use, and they want a space they'll actually sit in. When that's a bare slab out back, a patio-to-sunroom conversion is where a lot of these jobs start. The price moves mostly with the size of the room, whether it needs a new foundation, whether it's a three-season room or a four-season room you heat and cool, and what glass, insulation and shade go into it. The schedule usually turns on permits and inspections more than on the building itself, and your written estimate gives you the figure for your own room.
How we plan and build a custom sunroom
I start by asking how you'll use the room, because that decides whether you need a three-season or four-season room and how much glass makes sense. 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, so we settle that before anything is framed. We plan shade with you early too, whether that's blinds, outside shades or part of the roof made solid, so the frame is built ready to carry it. Then our crew sets the base, frames the room, ties it into the house, puts in the glass and roof, and finishes and cleans up.
Some jobs need more than a room on an existing slab. When you're starting from bare ground or need a new foundation, that's sunroom construction, and when you already have a room that runs hot, leaks or just isn't working, sunroom remodeling can often fix it without starting over.
Three-season room
A three-season room isn't heated or cooled and uses uninsulated windows or screens. It suits you if the room is mainly for mornings and evenings in spring and fall and you'd rather keep the build simpler.
Four-season room
A four-season room is fully enclosed, heated and cooled, and has all-weather windows. It suits you if you want to use it through summer heat and winter evenings like any other room in the house, and it's the room where insulation matters most.
Building a custom sunroom in Colton
In Colton, the city's Building and Safety office handles plan check, where the city reviews the drawings, along with permits and inspections for building construction. Permit applications go through the city's eTRAKit portal, which also shows inspection statuses and takes payments in one place, so you can follow along. Whether your particular room needs a permit isn't something I'll guess at from here. We confirm which building office covers your address, and when your project needs a permit, we prepare the plans, handle the paperwork and set up the inspections.
Most of what we see around Colton is patios that bake in the afternoon sun and older rooms that get too hot to use by midsummer, which is why glass and shade come up in our first conversation. We see the same thing on jobs in San Bernardino and Redlands, and we work in cities all around Colton, so if yours isn't listed, just ask.

Based in Colton since 2013
We started this company in Colton in 2013 and have been building and remodeling sunrooms, patio rooms and covers ever since. We know how a glass room holds heat through a summer here, so we plan the room around it.
Licensed and insured in California
The state contractor licensing board describes a general building contractor as one who builds structures that shelter and enclose people or property using at least two unrelated trades, and a sunroom usually fits that description. We're licensed and insured, which is worth asking any contractor about before they build onto your house.
The choice that matters most on this job is three-season or four-season, because it sets the windows, the insulation and the budget for everything else. Send us a message or call (909) 679-6010 and we'll talk it through.

Frequently asked questions
How much does a custom sunroom cost in the Colton area?
A sunroom in the San Bernardino area usually costs about $100 to $200 per square foot, and that's the going rate around here, not a quote from us. Larger rooms that need a foundation and have heating and air conditioning land at the higher end of that range. Your written estimate gives you the number for your own room.
What does a sunroom price per square foot usually leave out?
It can leave out more than people expect, since one price guide's per-foot figure for a three-season room doesn't include insulation, extending your heating or cooling, plumbing or permits. When you compare quotes, check whether those are in or out, because they can change the total quite a bit.
How do I keep a sunroom from getting too hot in Colton?
The two biggest things are the glass and the shade. Clear glass lets most of the sun's heat into a room, so ask which glass your sunroom will use, and plan the shade before framing, the way we do, so the room is built to carry it.
Does California's energy code affect how a sunroom is built?
It can, because the state's Energy Code sets standards for a building's walls and roof and for its windows and doors, and those standards depend on the climate zone the house is in. That matters most on a four-season room you'll heat and cool, so it's part of what we look at when we draw up the plans.
Can you build a sunroom on my existing patio slab?
Sometimes, once the slab has been checked. A Milpitas city handout advises finding out whether a slab is post-tension, with tensioned cables called tendons inside it, before anyone cuts or breaks it, because cutting a tendon can be very dangerous and expensive to repair. I look at your slab when I come out for the estimate.
What is the best way to take care of a sunroom roof?
Check the roof and gutters once a year and stay off the roof unless you really need to be up there, which is what one sunroom maker suggests. Catching a clogged gutter early is a lot easier than chasing a leak later.
