Three season sunrooms in Loma Linda CA - a bright room that stays comfortable
A covered patio you skip because of wind or bugs becomes a bright, closed-in room you'll use most of the year.
What is a three season sunroom, and is it right for my patio?
A three season sunroom in Loma Linda is an enclosed room with glass or clear panels in its openings, built onto your house but kept off your home's heating and cooling, so you get a bright, sheltered space without paying to condition another room.
Most people who call us have a covered patio, a slab or a deck they hardly use because of the wind, the dust or the bugs, and they want it closed in without adding another room to cool. The price moves with the size of the room, whether your slab or deck can carry it as is, the glass you pick and whether you want lights, outlets or insulation, and the schedule turns mostly on the city's review and on what I find under the base. If you're picturing a room you'll heat and cool all year, I'll point you to a four season sunroom instead, and either way the written estimate puts your own figure and my recommendation on paper.
What we do on a three season sunroom
A three season room has no heating or cooling of its own, so before anything else I talk honestly with you about how the sun will hit it and when the hot hours fall. From there we plan the overhangs and the glass together, deciding which walls get afternoon sun and how much clear glass each side should carry. Then our crew prepares the base, sets footings where the room needs them, frames the walls and roof, puts in the glass or panels, finishes the trim and cleans up before I walk it with you.
Some homeowners only need the sides closed in under a cover they already have, and that's a patio enclosure, usually the lighter job. If your house calls for an odd shape, a taller roof or a room that ties into the roofline in an unusual way, we design it as one of our custom sunrooms.
Three season sunroom permits and conditions in Loma Linda
Loma Linda's Building and Safety Division issues building permits, which most buildings and structures need, and it plan-checks proposed projects, additions to existing buildings included, before a permit goes out. Its list of examples names fences, walls, antennas and pools but says nothing about sunrooms, so that list doesn't settle whether a three season room needs one. That's a question for the division, and we ask it before we draw anything so you know where your job stands.
Most of the calls we get around Loma Linda are for covered patios on an older slab, often off a family room or kitchen, with a west or south side that takes the afternoon sun hard. That sun is the main thing I plan around, and we see the same patios on jobs in Redlands and Riverside.
How a three season sunroom gets built
Call us or send the form
Call (909) 515-5048 or use the form, and we'll set a time for me to come see the space. We take calls seven days a week.
I measure and check the base
I come out myself to measure, look at the slab or deck and hear what you want the room for. You get a clear recommendation and a written estimate that shows what's included and what would add to the price.
We file and the city reviews
When your room needs a permit, we put together the plans and paperwork and file them with the city's building office. Simple projects like patio covers are often checked on the spot at City Hall, but complex ones take 15 to 30 working days, so leave room in your schedule in case the city treats your room as complex.
We build, then walk through
Our crew builds the room in order so each stage is ready when the inspector comes. When it's done, I walk the finished room with you.
Get a written estimate for your three season room
We reply within one business day, and the estimate is free, done at your property, with no pressure and no obligation. Once you send the form, we call to set a time, and I come out myself to measure and look at your slab or deck.
Questions before you book a three season sunroom
How much does a three season sunroom cost near Loma Linda?
A three season room added to an existing base, labor included, usually runs about $95 to $140 per square foot in the San Bernardino area, which makes a good starting point for Loma Linda. That usual price covers standard-grade windows, siding, roofing, fixtures and electrical access, while insulation, extending your heating or cooling, plumbing and permits add to it. Your written estimate shows where your room lands.
Will a three season sunroom get too hot in the summer?
It can, so the sun has to be planned for before the glass is picked. Research from warm-climate countries notes that sunlight turning into heat inside a glassed room can lower comfort and raise the need for cooling, and a three season room has no cooling of its own. Roof overhangs can block direct summer sun from the windows while still letting the lower winter sun in, which is why I look at your patio's exposure first.
What is the best way to choose between a three season and a four season sunroom?
Pick a three season room if you want it closed off from the house and its heating and cooling, and a four season room if you want it open to the house and conditioned. The sunroom industry treats the three season type as space that isn't meant for everyday living, so if you'll use it every day all year, the four season room is the better fit.
Who can pull a building permit for a sunroom in Loma Linda?
The city says state law lets a licensed contractor or the property owner get the building permit. A friend or relative can apply with a letter of authorization from the owner. When your room needs a permit, we file it ourselves.
How do I know if my patio slab or deck can hold a sunroom?
Have it looked at before anything is designed, because the base has to carry the walls and roof of the new room, and I check it on the first visit. If a concrete slab might need cutting for footings, one California city's guidance advises finding out first whether it's a post-tension slab, which has steel cables under tension inside it, before anyone saws or breaks it. If your base can't hold the room, I'll tell you then rather than sell you something it can't carry.
Can I add lights and outlets to a three season sunroom in Loma Linda?
Yes, and most people want at least lights and a couple of outlets. In Loma Linda, electrical, plumbing or mechanical work on the plans needs its own permit, separate from the building permit, so tell me early and we'll include it in the filing.
Why Loma Linda homeowners call Loma Linda Sunrooms & Patios for three season rooms
I come out to every job
I look at every job myself, and our own crew does the building. The person who measured your slab is the one answering for the room.
Back building sunrooms since 2021
I built patio covers and sunrooms when I was younger, then came back to the trade and started this business in 2021. Five years in, turning old patios and decks into rooms people use is still most of what we do.
Fully licensed and insured crew
We're fully licensed and insured. That protects you and your property while our crew is working on your house.
Ready for each Loma Linda inspection
Loma Linda inspects a stage whenever the next one will cover it, like footings before the concrete goes in and open walls before insulation and finish go on. We schedule the work around those visits and I meet the inspector, so nothing has to be torn open to be checked.
Getting the base and the sun right before we build is what makes a three season room worth having, so set up a visit and I'll come take a look.
Other ways to close in your patio
Patio enclosures
If your patio cover is already solid, closing in just the sides may give you the shelter you want with less work.
Custom sunrooms
When a standard room won't fit your roofline or lot, we draw one up to suit the house.
Book a visit for your three season room
